Pricing, DX, and feature comparison of Auth0, Clerk, and Supabase Auth for indie hackers building MVPs in 2026.
You need auth in your app. You don’t want to spend a week setting it up. The three names that keep coming up are Auth0, Clerk, and Supabase Auth — but they target very different use cases and budgets.
Here’s what actually matters when you’re building an MVP and need to ship fast.
## Pricing: The Numbers That Matter
This is where most indie hackers start, and for good reason. Auth costs scale with your user count, and picking the wrong provider can turn a $0/month line item into a $500/month bill overnight.
Provider
Free Tier (as of July 2026)
Cost After Free Tier
Cost at 100K users
**Supabase Auth**
50,000 MAUs
$0.00325/MAU
~$163/mo
**Clerk**
50,000 MRUs
$0.02/MRU (Pro from $25/mo)
~$1,000/mo
**Auth0**
25,000 MAUs
Essentials from $35/mo (500 MAUs), ~$700/mo at 10K
Enterprise (custom)
Supabase still gives you the most room at scale, but the gap has narrowed: Clerk raised its free tier from 10K to 50,000 MRUs in February 2026 (an MRU only counts users who return 24h+ after signup, so it stretches further than a raw MAU cap). Auth0’s free tier is now 25,000 MAUs — generous on paper, but it lacks MFA and RBAC, and the jump to paid plans is steep.
## Developer Experience
### Clerk
Clerk was built for React and Next.js. You get drop-in components like ``, ``, and `` that work immediately with zero custom styling required. The setup is fast — most developers go from zero to working auth in under 15 minutes.
Clerk also handles user management UI out of the box. Your users get a profile page, session management, and multi-factor authentication without you writing any of that code.
The trade-off: Clerk is tightly coupled to its own ecosystem. If you’re not using React or Next.js, the experience isn’t as smooth.
### Supabase Auth
Supabase Auth is part of the broader Supabase platform. If you’re already using Supabase for your database (Postgres), real-time subscriptions, or storage, adding auth is a single function call. Row Level Security (RLS) policies tie directly into your auth users, so database permissions and authentication live in the same system.
The setup requires more manual work than Clerk — you’ll build your own login forms and manage the auth state yourself. But if you’re using Supabase for your backend anyway, adding auth costs nothing extra and keeps your stack simple. If you _don’t_ have a Supabase backend — say, a purely static site — see our [Supabase Auth alternative for static sites](https://beag.io/blog/supabase-auth-alternative-static-sites/) for why adopting the whole platform just for login rarely makes sense.
### Auth0
Auth0 is enterprise-grade authentication. It supports every identity protocol (SAML, OIDC, LDAP), has pre-built integrations with hundreds of enterprise tools, and handles compliance requirements like SOC 2 and HIPAA.
For indie hackers, this is almost always overkill. The dashboard is complex, the documentation assumes enterprise knowledge, and simple tasks require more configuration than they should. Auth0 makes sense when your customers require SSO or you’re selling to large companies. For a side project or early MVP, it adds unnecessary complexity — we’ve written up the [best Auth0 alternatives for indie hackers](https://beag.io/blog/auth0-alternative-indie-hackers/) with current pricing.

The biggest differentiator: Clerk gives you the UI, Supabase gives you the backend, and Auth0 gives you enterprise compliance. Pick based on what you need most.
## When to Pick Each One
### Pick Clerk if:
- You’re building with React or Next.js
- You want pre-built auth UI that looks good out of the box
- You need user management features (profile editing, session management) without building them
- You’ll stay under 50K returning users for a while, or the per-user cost is acceptable for your business model
- You plan to add Stripe payments later — Clerk pairs well with separate payment providers
### Pick Supabase Auth if:
- You’re already using Supabase (or planning to) for your database
- You want the cheapest option at scale
- You’re comfortable building your own auth UI
- You need Row Level Security for your database
- You want the option to self-host your entire auth stack later
- Budget is a primary concern and you’re pre-revenue
### Pick Auth0 if:
- Your customers require enterprise SSO (SAML/LDAP)
- You’re building B2B software for large companies
- Compliance certifications (SOC 2, HIPAA) are a hard requirement
- You have the budget to support enterprise-tier pricing
For most indie hackers building MVPs, the real choice is between Clerk and Supabase Auth. Auth0 enters the picture only when enterprise requirements force your hand.
## What About Beag?
If you want auth and Stripe payments handled together — without configuring either one separately — [Beag](https://beag.io/) bundles both into a single integration. Drop in auth, attach a payment plan, and start charging users in minutes instead of days. It’s built specifically for developers who want to ship fast and not spend a week wiring up authentication and payment boilerplate.

## FAQ
### Is Clerk free for small projects?
Yes. As of July 2026, Clerk offers 50,000 monthly retained users (MRUs) for free — raised from 10,000 in February 2026. After that, you pay $0.02 per additional MRU. For most MVPs and early-stage products, the free tier is enough to validate your idea before paying anything.
### Can I migrate from one auth provider to another later?
It’s possible but painful. Auth providers store user credentials (hashed passwords, OAuth tokens), and migrating that data requires export/import workflows that vary by provider. Supabase and Auth0 both support user migration APIs. Clerk offers import tools as well. Plan to spend a few days on any migration.
### Does Supabase Auth work without using Supabase’s database?
Technically yes — you can use Supabase Auth standalone. But the biggest advantage of Supabase Auth is its native integration with Postgres and Row Level Security. Using it without the database removes its main selling point. If you don’t need Supabase’s database, Clerk is likely a better fit.
### Which auth provider is best for a Next.js SaaS?
Clerk has the smoothest integration with Next.js, including App Router support, middleware-based auth, and server component compatibility. Supabase Auth also works well with Next.js through the `@supabase/ssr` package but requires more manual setup. Both are solid choices — Clerk for convenience, Supabase for cost savings at scale.
