Suggest a change- If you need enterprise SSO and SCIM directory sync for business customers and want the most generous free tier while you're small, choose WorkOS. AuthKit is free for the first 1 million monthly active users, and SSO and directory sync are priced per connection instead of bundled into one expensive add-on tier.
- If you want an established, Okta-backed platform with clear separate B2C and B2B pricing tracks and can absorb a higher bill for that stability, choose Auth0. it's owned by Okta, publishes a free tier of 25,000 monthly active users, and gives you dedicated B2C and B2B tiers instead of one generic plan.
- If you want a hosted login UI plus deep B2B organization hierarchies and fine-grained entitlements bundled into one free tier, choose Frontegg. its free Pay as you go plan already includes 5 SSO/SCIM connections and unlimited organizations, features Clerk sells as separate paid add-ons.
- If you'd rather call an API and build your own login screens than drop in someone else's prebuilt components, choose Stytch. it's built API-first for teams that want full control of the UI, with a free tier covering 10,000 monthly active users and native support for passkeys and OAuth CIMD.
- If you want to self-host auth and keep user data on your own infrastructure instead of depending on any hosted vendor, choose SuperTokens. the core auth system is open source and free to self-host with no user cap, unlike every other option here which only runs as a hosted service.
- If you're already shipping with Clerk's prebuilt components and haven't hit real monthly-retained-user cost pain yet, choose stay on Clerk. its free Hobby tier covers 50,000 monthly retained users, and its prebuilt UI components still get you to a working login screen faster than any option here.
Clerk is a fast way to add login, signup, and account management to a Next.js or React app without building those screens yourself. Teams start looking elsewhere for one of two reasons: the bill grows fast once real users show up, since Clerk charges per monthly retained user and treats B2B auth, admin tools, and billing as separate paid add-ons, or they need enterprise identity features like SCIM directory sync that Clerk doesn't fully cover on its own.
The five tools below all do the same core job as Clerk: handle login, signup, sessions, and user management so you don't write that code yourself. They split mainly on how much of the UI they build for you versus how much you build yourself, and on how they price growth as your user count climbs.

Why teams switch from Clerk
Costs climb fast as monthly retained users grow
Pro and Business both include 50,000 MRUs before overage kicks in at $0.02 per extra MRU, and a developer who moved from Clerk to Better Auth said Clerk's pricing "got a bit out of hand for side projects."
B2B features, admin tools, and billing are all separate paid add-ons
Broader B2B authentication costs $100/month, admin impersonation costs $100/month, and built-in billing costs 0.7% of billing volume on top of Stripe's own fees, all on top of the base plan.
Enterprise plan is quote-only and requires annual billing
Teams that outgrow the published Business tier have to talk to sales and commit to annual billing to get an Enterprise quote.
The best Clerk alternatives, ranked
WorkOS is the strongest fit for teams whose main complaint about Clerk is cost once they need B2B features. AuthKit, its hosted login and user management product, is free for the first 1 million monthly active users, a large jump up from Clerk's 50,000 monthly retained user free tier. Where Clerk bundles B2B auth into a $100/month add-on, WorkOS prices SSO and SCIM directory sync per identity provider connection, starting at $125/connection and dropping to $65/connection once you pass 50 connections. That per-connection model means the bill tracks how many enterprise customers you've actually signed, not a flat add-on fee. The tradeoff is that pricing is split across several metered line items, monthly active users, connections, audit log retention, so there's no single number to budget against the way there is with Clerk's tiers.
Pros
- + Core login and user management is free up to 1M monthly active users, so most apps pay nothing until they have real scale
- + SSO and directory sync pricing scales down per connection as you add more enterprise customers, up to 48% off once you reach 51-100 connections
- + AuthKit gives you a hosted, customizable login page so you don't have to design and maintain your own auth screens
Cons
- – Pricing is split across many separate metered items (MAUs, SSO connections, directory sync connections, audit log streams and retention, Radar checks, custom domain), so there's no single number that tells you what you'll pay
- – Each SSO connection still costs $125/month at low volume, which adds up fast if you sign many small enterprise customers who each bring their own identity provider
Auth0, now sold under Okta, is the safest choice for teams that want an established vendor with a long track record rather than a newer entrant. Its free plan covers 25,000 monthly active users with real features like SSO and SCIM, and it splits pricing into separate B2C and B2B tracks so a consumer app and a multi-tenant SaaS product aren't priced the same way. That clarity comes at a cost: at 10,000 monthly active users, B2C Essentials runs $700/month and B2B Essentials runs $2,100/month, both well above what Clerk charges at similar volume. Extra SSO connections and Enterprise MFA are separate paid add-ons on top of that. Auth0 makes sense when you value Okta's infrastructure and support over the lowest possible bill, and can accept that crossing the top published tier pushes you into quote-only Enterprise pricing.
Pros
- + Free plan covers up to 25,000 monthly active users with real features (SSO, SCIM), not just a stripped-down trial
- + Separate B2C and B2B tracks match pricing to how the app is actually used
- + Backed by Okta's infrastructure, with published uptime and attack-blocking numbers
Cons
- – Per-MAU pricing gets expensive fast once you cross a few thousand users, especially on the B2B track
- – Several needed pieces (extra SSO connections, MFA, AI Agents) are separate paid add-ons, not included in the base tiers
Frontegg
Frontegg looks closest to Clerk's actual shape: a hosted login UI plus B2B features like organizations and SSO, aimed at SaaS teams rather than pure consumer apps. Its free Pay as you go plan covers 7,500 monthly active users and includes 5 enterprise SSO/SCIM connections and unlimited organizations, features Clerk only unlocks through separate paid add-ons. Frontegg also bundles fine-grained entitlements and authorization tooling into the same product, plus newer identity features for AI agents through AgentLink and FrontMCP. The catch is that Frontegg only publishes two plans, free and quote-only Enterprise, so there's no visible middle tier or published overage rate once you outgrow the free allotment. Teams that want to see exact pricing at scale before committing will need a sales call, something Clerk mostly avoids until you reach its own Enterprise tier.
Pros
- + Free tier covers a real amount of usage: 7,500 monthly active users and 5 SSO/SCIM connections
- + B2B features like organizations, hierarchies, and entitlements are built in, not bolted-on add-ons
- + Covers machine-to-machine and AI agent identity use cases beyond plain end-user login
Cons
- – No published price past the free tier. Overage rates for extra MAUs and connections aren't on the pricing page, so you can't estimate cost at scale without a sales call
- – Only two named plans, so there's no visible middle tier between free and custom Enterprise pricing
Stytch fits teams whose issue with Clerk isn't price but control: it's built API-first, so you call its endpoints or use its components on top of your own frontend rather than dropping in a component library. The free tier covers 10,000 monthly active users with SSO, RBAC, and sessions included, and its B2B product ships an admin portal your customers can use to manage their own SSO and SCIM setup. Stytch also supports newer methods like passkeys and OAuth CIMD ahead of some competitors. The real tradeoff shows up past the free tier: the core per-MAU overage rate isn't published, only two specific add-on fees are, SSO/SCIM connections at $125/month and fraud fingerprints at $0.005 each, so you can't fully budget without a sales conversation. Twilio's October 2025 acquisition also adds some uncertainty about where pricing goes next.
Pros
- + Free tier covers 10,000 MAU with core features like SSO, RBAC, and sessions, not a crippled trial
- + Clean, well-documented API with SDKs for most major frameworks
- + B2B product handles multi-tenant SSO/SCIM and org management out of the box, which most competitors bolt on later
Cons
- – The real cost past the free tier isn't public. You only see two specific overage fees (SSO/SCIM connections, fraud fingerprints); the core per-MAU rate requires a sales conversation
- – Extra SSO/SCIM connections cost $125/connection/month, which adds up fast if you sell to many enterprise customers each needing their own connection
SuperTokens is the pick for teams that want to leave the hosted-vendor model behind entirely, something none of Clerk, Auth0, WorkOS, Stytch, or Frontegg let you do. You can self-host the open source core with no monthly active user cap at all, paying nothing unless you turn on add-ons like MFA or account linking, each billed per MAU with a $100/month minimum. There's also a managed cloud option, free up to 5,000 MAU, if you'd rather not run the servers yourself but still want the open source code underneath. The backend SDKs for Node, Python, and Go are well regarded, though the docs' recipe-based structure and the React SDK have both drawn criticism from developers. SuperTokens is not the pick if you want Clerk's level of prebuilt UI polish out of the box.
Pros
- + Core auth is genuinely free to self-host with no MAU limit, not just a trial
- + Node.js SDK is solid and most functions can be overridden for custom flows
- + Managed cloud free tier (5,000 MAU) is generous for early-stage products
Cons
- – MFA, account linking, and extra dashboard users are billed separately per MAU with a $100/month minimum each, so real cost adds up fast once you need more than basic login
- – Docs are built around a "recipes" abstraction that developers on Hacker News describe as confusing to search and navigate
Clerk alternatives: FAQ
What is the best free Clerk alternative?+
WorkOS has the most generous free tier of this group. AuthKit is free for the first 1 million monthly active users, compared to Clerk's 50,000 monthly retained users.
Is there a Clerk alternative I can self-host?+
Yes. SuperTokens is open source and free to self-host with no user cap, letting you keep user data on your own infrastructure instead of depending on a hosted vendor.
Which Clerk alternative is best for B2B SaaS that needs SSO and SCIM?+
WorkOS and Frontegg both build SSO and SCIM directory sync into their core product rather than treating it as an afterthought. WorkOS prices connections individually with volume discounts, while Frontegg bundles 5 connections into its free tier.
Why do teams leave Clerk?+
Cost is the most common reason. Clerk's per-monthly-retained-user pricing climbs quickly once an app has real usage, and B2B auth, admin tools, and billing are all separate paid add-ons on top of the base plan.
