Clerk alternatives: which complaint each one actually fixes
Clerk's 2026 pricing raised the free tier, added per-organization metering to the B2B add-on and left the UI lock-in alone. Which alternative fixes which complaint, and where BuildBase fits.
In short
Clerk raised its 2026 free tier but left the real complaints standing: a B2B bill that grows with every customer org past 100, and UI components wired deep enough into your app that leaving means a rewrite. WorkOS, Supabase, SuperTokens and Kinde each fix one specifically; this covers which and where BuildBase fits.
Clerk raised its free tier to 50,000 monthly retained users this year. Every "Clerk alternatives" post written before that update is now arguing against a version of Clerk that does not exist anymore - which means the shortlist most people are reading is answering the wrong complaint.
The one-paragraph answer
If your complaint is what Clerk charges for B2B organizations, look at WorkOS - AuthKit is free to the first million monthly active users, and enterprise features are priced per connection, so you pay for the enterprise customers you have rather than for every customer org you sign up. If your complaint is that Clerk's prebuilt UI components and middleware are wired too deep into your app to leave easily, SuperTokens is the direct answer, because the same code runs self-hosted. If you want auth bundled with the Postgres database you are probably already running, that is Supabase. If you want the most generous free tier with billing and B2B orgs already included, that is Kinde. And if the real gap was never just auth - if it was auth plus billing plus workflows plus RBAC all needing to agree with each other - BuildBase replaces more of the stack at once, though it does not ship SSO or the UI kit Clerk is known for.
What actually changed
Most "Clerk alternatives" content still argues from the old pricing shape: a low free-user ceiling that made Clerk feel expensive the moment a product got real traction. That argument does not hold anymore. As of our last check on Clerk's own pricing (verified 24 September 2026, see the full breakdown), the free Hobby plan covers 50,000 monthly retained users, Pro is $25 a month and Business $300 a month, all three carrying the same 50,000 included before overage kicks in at $0.02 per extra user.
What changed for B2B is the part that actually drives people to look elsewhere. The enhanced B2B add-on is still $100 a month ($85 billed annually), now covering all of your applications, and Clerk also meters organizations: 100 monthly retained organizations are included per app, and each one after that is $1 a month. A team serving five customer orgs pays the add-on and nothing more; a team serving five hundred pays the add-on plus about $400 a month. Enterprise connections are billed on top of both - one included on Pro and Business, $75 a month each for the next fourteen, then $60, less at higher volume. And Clerk's UI components and session middleware are genuinely good, which is exactly why they are hard to leave - the sign-in flow, the org switcher, the session handling are all wired into your app in a way a simple SDK swap does not undo.
Where each alternative fits
WorkOS - the B2B organizations tax. WorkOS unbundles "enterprise readiness" from the core product. AuthKit is free for the first 1M monthly active users, then $2,500 a month per additional million, and the enterprise pieces are metered as you turn them on: SSO and directory sync are each $125 per connection per month for the first 15, sliding to $100 at 16-30, $80 at 31-50 and $65 at 51-100, with custom pricing past that, and audit log streaming is $125 a month per SIEM connection. The shape is the point. You pay for the enterprise customers you actually have, where Clerk charges for every customer organization past the first 100, enterprise or not.
Supabase - "I already have Postgres." Supabase treats auth as one feature of a full backend: database, storage, realtime and edge functions on the same plan. The free plan covers 50,000 monthly active users, Pro is $25 a month with 100,000 included and $0.00325 per MAU after that, and Team is $599 with the same allowance. If the appeal of leaving Clerk is consolidating onto infrastructure you already run rather than adding another point vendor, this is the shape that fits, and it is open enough to self-host if that matters later. If Postgres itself is not the settled part yet, the Supabase alternatives roundup is worth reading before you commit to it as the destination.
SuperTokens - the lock-in complaint, directly. SuperTokens' core is open source. The managed cloud and the self-hosted version run the same code, so choosing the managed option now does not forfeit the option to self-host later if the pricing or the relationship stops working. Managed cloud is free to 5,000 MAUs and $0.02 per MAU beyond that; self-hosting the core carries no MAU ceiling and no licence cost. Read the add-on line before you assume self-hosting is free, though: MFA is $0.01 per MAU and account linking $0.005 per MAU, each with a $100 monthly minimum, which is a real floor at small scale. This is the pick for the reader whose actual objection to Clerk is "I do not want my auth logic living inside someone else's components again."
Kinde - the generous-free-tier pick. Kinde's free plan includes 10,500 MAUs, B2B organizations and subscription billing, rather than charging a separate add-on for either, which is a direct answer to Clerk's organizations charges. It takes a cut of each transaction if you bill customers through it: 0.7% on Free and Pro, 0.6% on Plus and 0.5% on Scale. Paid plans are Pro at $25, Plus at $75 and Scale at $250, all with the same 10,500 MAUs included. The unbundled-SSO claim holds up on Kinde's own page: enterprise connections are capped at one on Free and Pro, then unlimited at no additional cost from Plus ($75) upward. That is the sharpest single contrast in this post, because on Clerk every connection after the first is billed on its own, from $75 a month. See Kinde vs BuildBase for how it compares to a bundled SDK rather than to Clerk specifically.
| Feature | BuildBase | Clerk |
|---|---|---|
| Scope | 20 modules: auth, billing, workflows, RBAC, one instance | Auth and user management, billing via your own Stripe account |
| B2B organizations | Included | $100/mo enhanced B2B add-on, plus $1/mo per organization past 100 per app |
| Enterprise SSO / SAML | Not available | 1 connection included on Pro and Business, then from $75/mo each |
| Prebuilt UI components | Not a focus - bring your own UI against the SDK | Extensive prebuilt React/Next.js components |
| Framework support | Next.js, Vite, React Router / Remix, TanStack Start, Express, NestJS, Fastify, Hono, Astro | Next.js, React, Vue, Nuxt, Expo/React Native, and more |
Where Clerk wins
Clerk's prebuilt UI components are the best in this category, and that is not a small thing. The sign-in and sign-up flows, the org switcher, the user profile screen - they drop into a Next.js app in minutes and look finished immediately, which is a real head start every one of the alternatives in this post, BuildBase included, asks you to build more of yourself. If fastest time-to-first-login is what you are optimizing for and you are not yet running into the organizations pricing or the lock-in it creates, Clerk is still a genuinely good choice, and this post is not an argument that everyone should leave.
How to actually decide
Match the alternative to the complaint you actually have, not the one everyone else is writing about. If it is cost at your current B2B shape, price out WorkOS vs BuildBase side by side with WorkOS's own connection-based model. If it is "I don't want to be locked into anyone's components again," SuperTokens' open-source core solves that more directly than any hosted vendor can. If the honest answer is that auth was never the only piece you were short - that billing and workspaces and workflow automation were always going to be separate purchases too - Clerk vs BuildBase and Supabase vs BuildBase cover that comparison from two different starting points, Clerk's and Supabase's.
Every figure above was read off each vendor's own pricing page and verified 24 September 2026: clerk.com/pricing, workos.com/pricing, supabase.com/pricing, supertokens.com/pricing and kinde.com/pricing. Auth pricing moves faster than most software pricing, and Clerk's own 2026 change is the proof, so check the source page before you commit a budget to any of these.
