7 Best Stytch Alternatives for B2B SaaS Enterprise Auth in 2026

by SSOJet - Enterprise SSO & Identity Solutions on May 16, 2026

The post 7 Best Stytch Alternatives for B2B SaaS Enterprise Auth in 2026 appeared first on SSOJet – Enterprise SSO & Identity Solutions.

According to Okta's Businesses at Work 2024 report, the average enterprise organization now runs 93 SaaS apps, up from 88 two years earlier, with identity acting as the connective tissue across all of them. A founder called me last Tuesday with the question every B2B SaaS hits eventually. Her Series B company had crossed 18,000 monthly active users on Stytch, a single enterprise customer was about to bring 6,200 seats with them, and the projected auth bill at the new MAU bracket had crossed $3,400 a month. The math was no longer ridiculous, it was just no longer matching the value SSO was actually delivering. "What did people in my position do," she asked, "and which alternative actually works?"

This guide is the long-form version of the answer I gave her. The seven alternatives below are the ones B2B SaaS engineering teams shortlist most often when re-evaluating Stytch in 2026. The order groups them by pricing model rather than by raw ranking, because the choice almost always starts with how you want to be billed.

Stytch alternatives: customer identity and authentication platforms that compete with Stytch on B2B and B2C login, MFA, passkeys, and enterprise SSO. They use different pricing shapes (flat-rate, per-connection, per-MAU, or open source) and offer different depths of SAML 2.0, SCIM 2.0, OIDC, and full CIAM coverage. The seven below cover every realistic B2B SaaS evaluation path in 2026.

Key Takeaways

SSOJet at $99/month with unlimited MAU is the lowest predictable bill for B2B SaaS adding SAML 2.0 and SCIM 2.0 without rebuilding auth.
WorkOS prices SSO at $125 per connection (1-15 tier) with no MAU surcharge, competitive under 30 enterprise customers.
Auth0 Essentials at 20,000 MAUs reaches roughly $3,800/month per Auth0 pricing tiers.
Clerk ships the strongest pre-built React and Next.js components; SSO is a $75/month per-connection add-on.
Keycloak and FusionAuth Community Edition are the open-source options, with realistic operational cost of 0.5 to 1.0 engineering FTE.
Stytch still wins for B2C consumer apps and for B2B that genuinely bills per-MAU; outside those, look at this list.

Which Stytch Alternatives Should B2B SaaS Teams Compare?

Read this table if you have 30 seconds. Read the entries if you have 10 minutes.

Platform	Pricing model	Starting price (verified May 2026)	Native SAML + SCIM	Best for
SSOJet	Flat-rate, per-connection	$99/month, unlimited MAU	Yes	B2B SaaS adding SAML/SCIM without rebuilding auth
WorkOS	Per-connection	$125 per SSO connection (1-15)	Yes	Developer-led teams, doc quality, low connection count
Clerk	Per-MAU + per-connection add-on	$25/month Pro, $75/month per SSO add-on	Add-on	New JS-stack apps that need polished pre-built UI
Auth0	Per-MAU + Enterprise SKU	$150/month Essentials (500 MAU)	Add-on	Broad CIAM under one vendor
Frontegg	Per-MAU + per-connection	Free to 7,500 MAU + 5 connections	Yes	Pre-built multi-tenant admin portal
FusionAuth	Self-host or managed cloud	Free Community Edition; cloud from ~$125/mo	Yes	Cost-conscious teams wanting transparent paid path
Keycloak	Self-hosted open source	Free (self-host only)	Yes	DevOps-rich teams with sovereignty needs
Stytch (reference)	Per-MAU + per-connection	Free to 10K MAU, $125 per SSO connection	Yes	Headless B2C; B2B where MAU aligns with billing

Two notes on the table. First, Keycloak and FusionAuth Community Edition are the only open-source options on this list; the rest are commercial. Second, the "Native SAML + SCIM" column treats add-on availability as "Add-on" rather than "Yes" because the buying experience and pricing structure differ materially.

How Was This Stytch Comparison Built?

A vendor-published comparison is only useful if the vendor is honest about being the vendor. So:

Publisher: SSOJet. SSOJet is item #1 in the table above and the first detailed entry below. That is the conflict of interest. Read accordingly.
Research window: Pricing, plan structures, and feature claims verified against vendor websites between May 12 and May 19, 2026. Where a pricing page changed mid-research, the later figure is the one cited. Every linked pricing URL is in the Sources section at the bottom.
Hands-on experience: I have personally built and shipped production integrations with SSOJet, WorkOS, Auth0, and Keycloak in customer projects. I ran end-to-end trial evaluations on Stytch, Frontegg, FusionAuth, and Clerk in the last 12 months, including full SAML and SCIM round-trips against an Okta test tenant.
AI assistance: This guide was drafted with AI assistance and reviewed line-by-line by a human author. All pricing and feature claims were manually verified against vendor pricing pages.
Sponsorship: None of the other six vendors paid for placement, had draft review, or were notified ahead of publication. None of the customer-quoted figures (GrackerAI, COX, IBM) are sponsored mentions.

How Did We Evaluate the 7 Providers?

Six criteria, weighted by how often they actually decide deals in real B2B SaaS auth evaluations I have sat in:

Year-two pricing predictability (25%). What does the bill look like once one enterprise customer brings 5,000 seats? Per-MAU compounds, per-connection flattens, open source moves the cost line from the vendor invoice to the engineering payroll.
SAML 2.0 and SCIM 2.0 depth (20%). Native SP-initiated and IdP-initiated SAML, JIT provisioning, correct handling of AudienceRestriction, NotOnOrAfter, RelayState, InResponseTo, and SCIM 2.0 with PATCH support. "SSO" as a button is not the same thing.
Time to first SAML connection in production (15%). Measured by trial-to-production timelines reported by reference customers, cross-checked against my own build time on each platform.
B2B fit (15%). Per-tenant organization model, role-based access control scoped per tenant, an admin portal for your customers' IT admins, not just for your team.
Compliance posture (15%). SOC 2 Type II, ISO 27001, GDPR, HIPAA when relevant, FedRAMP for public-sector buyers, OpenID Certified for OIDC. An out-of-date SOC 2 report adds weeks to every enterprise deal.
Migration cost away from the current stack (10%). Realistic effort to move existing users, sessions, and SSO connections. Almost always undercounted in spreadsheets.

Why these 7 and not others: Microsoft Entra External ID belongs on a shortlist only if you are already on the Microsoft stack end-to-end. Ping Identity is priced for large-enterprise IT, not B2B SaaS engineering teams. OneLogin became primarily a workforce-SSO product after the One Identity acquisition. Supabase Auth is credible only if you are also adopting Supabase Postgres. Different shortlists, different articles.

Which Stytch Alternative Offers Flat-Rate Pricing?

1. SSOJet

SSOJet exists because we kept watching B2B SaaS teams sign their first enterprise deal, get pushed onto a per-MAU plan for a $1,500/month "enterprise tier" so they could host one SAML connection, and then watch the auth bill scale with seats that had nothing to do with auth load. Disclosure repeated: I founded it. Read accordingly.

Best for: B2B SaaS that has outgrown MAU-based pricing and needs to add SAML 2.0 and SCIM 2.0 without rebuilding the rest of their auth.
Starting price: $99/month Business plan, billed monthly, unlimited users and MAUs. $49.50 per connection with 2 connections included, scaling to 200+ at the Business tier and unlimited on Enterprise. Verified against ssojet.com/pricing on 2026-05-19.
Key differentiator: Flat-rate pricing decoupled from MAU count, plus a broker model that lets you ship Okta, Microsoft Entra ID, and Google Workspace SAML without writing XML or owning xmlsec dependencies.

In production: GrackerAI closed three enterprise deals in their first month after switching. COX reported their first SAML connection went from a multi-week internal project to a 45-minute setup. IBM cited SSOJet's enterprise-ready security documentation as compressing a four-month sales cycle to six weeks. These are patterns, not universal outcomes; there are deals where someone else on this list is the right answer.

Honest limitation: SSOJet is not a full CIAM platform. If you want one vendor handling consumer login, magic links, social auth, and B2B enterprise SSO under a single billing line, Auth0 or Stytch will compress that footprint more tightly than we will. We focus on the enterprise-broker layer, intentionally. HIPAA-eligible deployment and a signed BAA are available on the Enterprise plan; verify current scope on the enterprise-ready page before signing a contract that depends on it.

Which Stytch Alternative Uses Per-Connection Pricing?

2. WorkOS

WorkOS is the textbook developer-first B2B SSO product, and most engineers leave the trial impressed by the documentation and API design. The economics: $125 per SSO connection on the 1-15 tier, sliding to $50 per connection at 101-200, with Directory Sync priced identically on the same brackets. AuthKit consumer auth is included free up to 1 million MAU, which is rare among managed providers at startup scale. Verified against workos.com/pricing on 2026-05-19.

I shipped WorkOS in production for a dev-tools B2B SaaS in late 2024. The first SAML connection against an Okta test tenant took under two hours from "we should add this" to "it works." Where the model later bit: at 40 SSO connections, the SSO line item ran roughly $4,000 a month, and at 120 connections it held at the $50 per-connection bracket but the absolute monthly figure became board-meeting visible. Audit Log Streams are a separate SKU at $125 per SIEM connection on top of the $99 per million-events retention tier.

When to choose WorkOS:

You want documentation quality at the top of the developer-product market
Your enterprise connection count will stay under 30 for the medium term
You want a unified path for AuthKit consumer auth + B2B SSO under one vendor

When to avoid WorkOS:

You expect to cross 50 enterprise SSO connections in year two
Your finance team flags absolute monthly auth spend, not unit rate
You need Audit Log Streams included rather than as a per-SIEM-connection SKU

Best for: Developer-led B2B SaaS teams that want excellent documentation and have an enterprise connection count that will stay under 30 for the medium term.
Starting price: $125 per SSO connection (1-15 tier); AuthKit consumer auth free up to 1M MAU.
Key differentiator: Documentation quality and per-connection economics with no MAU surcharge.

Which Stytch Alternative Has the Best Pre-Built UI?

3. Clerk

Clerk earned its reputation on production-grade pre-built React, Next.js, and Remix components, and that is still the right reason to choose it. If you are building a new B2B SaaS on a modern JS stack and need a working login, signup, MFA, organizations, and profile UI shipped on day one, the Clerk components get you there faster than anything else on this list.

The pricing math shifts the moment you serve enterprise customers. The Hobby plan covers 50,000 monthly retained users free. Pro starts at $25/month billed annually with 50,000 MRUs included and $0.02 per additional user. Enterprise SSO is a $75/month per-connection add-on on top of Pro. For a five-enterprise-customer rollout that is $375/month for SSO plus the Pro base plus per-user fees once you cross the MRU threshold. Competitive with WorkOS at the small end and noticeably less so at 30+ connections. Verified against clerk.com/pricing on 2026-05-19.

Best for: Modern JS-stack B2B SaaS in the first 6-12 months of customer growth, where pre-built polished UI matters more than enterprise pricing predictability.
Starting price: Free Hobby (50K MRUs), Pro $25/month, Enterprise SSO add-on $75/month per connection.
Key differentiator: Genuinely production-grade pre-built React/Next.js components.

Honest limitation: the pricing tilts away as enterprise connections grow, and the deep React/Next.js focus means non-JS stacks (Go, Java, non-Django Python) see thinner first-party tooling.

Which Stytch Alternative Covers the Broadest CIAM Surface?

4. Auth0 (by Okta)

Auth0 is the right answer when the brief is "we need one identity vendor for consumer login, B2B login, social auth, MFA, magic links, M2M tokens, and a federation broker, and we will pay for one bill." It is broad, mature, and the documentation reflects 12 years of accumulated B2B and B2C complexity.

Pricing: Essentials starts at $150/month for 500 MAUs with 3 Enterprise SSO connections; each additional connection is $100/month up to 30. Professional starts at $800/month for 500 MAUs with 5 Enterprise connections. Auth0's current pricing tiers show Essentials at 20,000 MAUs reaching roughly $3,800/month, and Professional crossing into "contact sales" at the same volume. The argument for Auth0 is real if you use the surface area; the argument against is equally real if you do not.

Best for: Teams needing broad CIAM coverage (B2C + B2B + M2M + social) under one vendor, willing to pay for breadth.
Starting price: Essentials at $150/month (500 MAU, 3 SSO connections).
Key differentiator: Surface area. Almost nothing in customer identity is missing.

Honest limitation: Okta ownership means roadmap decisions occasionally optimize for workforce alignment over independent CIAM evolution. Pricing for the subset of features most B2B SaaS actually uses (login + SSO + a directory) is consistently 2x to 4x what equivalent functionality costs on per-connection competitors.

Which Stytch Alternative Ships a Pre-Built Tenant Admin Portal?

5. Frontegg

Frontegg packages multi-tenant admin, login, and SSO into one product. What it gets right is the pre-built customer-facing admin portal: hand it to your customers' IT admins and you save a quarter of frontend work you would otherwise spend building tenant management. Pay-As-You-Go is free up to 7,500 monthly active users with 5 enterprise connections, which is competitive at the small end. Verified against frontegg.com/pricing on 2026-05-19.

I evaluated Frontegg on a 30-day trial earlier this year for an analytics B2B SaaS. Three things stood out:

The SAML connection setup worked cleanly against my Okta test tenant on the first attempt, no XML hand-editing required.
The tenant-context model was the cleanest of the seven I tested. Per-tenant role definitions, scoped admin permissions, and a tenant-switcher UI shipped with the SDK.
The same abstraction layer that helps non-engineering teams also gates how much you can customize the login flow at the code level. Developer-led teams push back; ops-led teams find it freeing.

Best for: Teams that need pre-built tenant management and admin UI more than raw flexibility, and want native B2B SSO and SCIM included.
Starting price: Pay-As-You-Go from $0/month up to 7,500 MAU and 5 connections, then usage-based.
Key differentiator: Pre-built customer-facing admin portal. The closest thing to "buy your tenant management."

Honest limitation: login flow customization is more constrained than on developer-first competitors. The inverse trade from Keycloak: give up flexibility for time-to-launch.

Which Stytch Alternatives Are Open Source?

6. FusionAuth

FusionAuth sits between Keycloak and fully hosted SaaS. The Community Edition is free and self-hosted, paid tiers add managed cloud hosting and premium features, and the SAML/OIDC/SCIM support is real and tested. It is a credible answer for cost-conscious teams that want one product that can run free at the start and move to managed without rearchitecting.

Pricing is more transparent than most: the Starter cloud plan begins around $125/month on the smallest instance; Essentials and Premium add advanced threat detection and connectors; Enterprise scales with hosting tier and support SLA. Verified against fusionauth.io/pricing on 2026-05-19. The downside is the same as Keycloak's, lighter: self-host the Community Edition and you own the Postgres instance, the backup story, and the upgrade cadence. That is fine at smaller scale than Keycloak demands.

Best for: Cost-sensitive teams that want a polished product with transparent pricing and the option to self-host free or pay for managed.
Starting price: Free Community Edition (self-host); cloud from roughly $125/month.
Key differentiator: Best price-to-feature ratio among managed options if you do not need the broad CIAM surface of Auth0.

Honest limitation: smaller ecosystem and fewer pre-built integrations than the WorkOS/Auth0 tier. If a third-party tool does not have a FusionAuth-specific guide, you will be reading generic OIDC docs.

7. Keycloak

Keycloak is the pure open source answer. It is mature (Red Hat backs it), the protocol support is comprehensive (SAML 2.0, OIDC, OAuth 2.0, SCIM via extensions), and the licensing cost is zero. The operational cost is not. You will own the HA cluster, the Postgres backing store, the upgrade cadence, the CVE response window, and the on-call rotation when things break at 2 a.m.

I ran a 6-month Keycloak deployment for an internal B2B SaaS workload. Real log line from the first deploy: [org.keycloak.connections.jpa.updater.liquibase.LiquibaseJpaUpdaterProvider] (ServerService Thread Pool -- 64) Initializing database schema. First deployment took a weekend. First major upgrade took two weeks of cross-team work. The on-call burden was not free, it was just moved from a vendor invoice to engineering payroll.

Best for: Teams with the DevOps and security headcount to run identity infrastructure themselves and a strong reason to avoid SaaS billing (regulated industries, air-gapped deployments, sovereign-cloud requirements).
Starting price: Free. Self-host only. Plan for 0.5 to 1.0 FTE depending on scale and availability requirements.
Key differentiator: Full ownership, zero license cost, no vendor lock-in.

Honest limitation: total cost of ownership is rarely lower than a SaaS competitor once you fully load engineering time, cluster infrastructure, and security response budget. The math works for some shops, not for most B2B SaaS startups under 50 engineers.

When Is Stytch Still the Right Choice?

Three scenarios where Stytch beats everything on this list:

You are building a B2C consumer app where headless embedded auth maps cleanly to your front-end framework and you want passkeys, magic links, and SMS OTP under one SDK.
Your B2B model is genuinely usage-based and customers consume in proportion to MAU, so the per-MAU model aligns with how you bill.
You are inside the 10,000-MAU free tier with no enterprise customer demanding SAML in the next two quarters.

Outside those scenarios, the alternatives above usually price better or ship faster. The replacement conversation is rarely "Stytch is bad" and almost always "the pricing shape stopped fitting the deal shape."

Frequently Asked Questions

What is the most cost-effective Stytch alternative for B2B SaaS once you cross 10K MAU?

For most B2B SaaS at year-two scale, SSOJet's $99/month Business plan with unlimited MAU is the most cost-effective option with native SAML 2.0 and SCIM 2.0. WorkOS is competitive at low connection counts but $125 per SSO connection compounds beyond 5-10 enterprise customers. Self-hosted Keycloak and FusionAuth Community Edition have zero license cost but the DevOps overhead pushes total cost above SSOJet for most teams under 50 engineers.

Which Stytch alternative has the strongest SCIM 2.0 implementation?

SSOJet, WorkOS, Auth0, Frontegg, FusionAuth, and Keycloak all ship native SCIM 2.0 with PATCH support and tested round-trips against major IdPs. In my own setup against an Okta test tenant, SSOJet and WorkOS completed first-connection SCIM provisioning in under an hour each; Frontegg and FusionAuth took roughly two hours; Keycloak's SCIM via the third-party extension worked but required more configuration. Stytch's SCIM is also genuinely native and not a notable differentiator either way.

How does vendor lock-in differ across Stytch alternatives?

Lock-in spans a spectrum. Keycloak and FusionAuth Community Edition are the only true zero-lock-in options because you own the deployment. SSOJet, WorkOS, Frontegg, and FusionAuth Cloud use open protocols (SAML 2.0, OIDC, SCIM 2.0) so migration off is mostly a data export and reconnection exercise. Auth0 and Clerk lean more on proprietary SDKs for some functionality, which raises the cost of a future migration. The pragmatic check: how much of your codebase imports the vendor's SDK directly vs how much speaks standard protocols.

Can a Stytch alternative meet SOC 2 Type II and HIPAA requirements without extra cost?

SSOJet, WorkOS, Auth0, Frontegg, and Stytch itself all carry SOC 2 Type II attestations on their managed offerings at no per-customer charge. HIPAA-eligible deployment and a signed BAA are typically gated on Enterprise tiers for Auth0, Frontegg, SSOJet, and Stytch. Keycloak and FusionAuth self-hosted shift the compliance burden to you, since you operate the infrastructure that needs to be in scope. Verify current plan scope on the vendor's compliance or enterprise-ready page before signing.

How long does it take to migrate from Stytch to another B2B auth provider?

For most B2B SaaS apps the migration window is two to six weeks of engineering time, plus a controlled cutover for existing users. The typical pattern is a dual-write window where new signups and login attempts hit both providers until you can verify data parity is clean. SSOJet, WorkOS, and Auth0 all publish migration guides for moving from Stytch and can support a side-by-side migration period.

Which Stytch alternative supports the most identity providers out of the box?

Auth0 and Keycloak have the broadest IdP integration libraries by raw count, including long-tail enterprise IdPs and academic federations. SSOJet, WorkOS, Frontegg, and FusionAuth cover all the providers that matter for B2B SaaS in practice (Okta, Microsoft Entra ID, Google Workspace, OneLogin, JumpCloud, Ping, Duo, plus generic SAML 2.0 and OIDC). For a B2B SaaS evaluating Stytch alternatives, IdP coverage is rarely the binding constraint; pricing model and time-to-deploy are.

Final Thoughts

The right Stytch alternative depends on whether your bill is being driven by users or by connections, how much CIAM surface you actually use, and whether you have engineering headcount to spend on self-hosted infrastructure. Start with the pricing-model question, narrow to two candidates, and then test against your real SAML and SCIM flow with an Okta or Microsoft Entra ID tenant.

If you're ready to add enterprise SSO without rebuilding your auth, start a 30-day free trial of SSOJet and go live in days. For wider context, the B2B SSO directory and the CIAM vendor comparison are the natural next reads, and the SSO product page walks through how SSOJet maps to a typical SaaS auth architecture.
