Trade-offPer-user pricing grows with you; users live in Clerk, not your database.

Choose Supabase if

Cost as you grow

Both cost $0 up to 50k MAU; from 100k MAU Supabase costs less ($25 vs $1,025); and still does at 1M MAU ($2,950 vs $17,225). They're different kinds of tool — hosted service and bundled with your backend — so the prices don't buy the same thing.

What makers say

Makers on using it for authentication, from Product Hunt and Starter Story interviews, each linked to the source. Products with a page of their own and fuller notes first.

On Clerk
The team loves Clerk for its intuitive interface, seamless integration, and efficient management of administrative tasks, allowing them to focus on building groundbreaking solutions.
Garple, the makerSep 2026 ↗
We used Clerk for account management. Building an authentication infrastructure from scratch is challenging, but by using Clerk’s abstracted API, we were able to simplify this process.
Hanabi.rest, the makerSep 2026 ↗
Nobody wants to worry about authentication or build their own system. Clerk allowed me to simply integrate them into my project and immediately feel confident in the security of my site.

On Supabase
Our real-time database and auth backbone. Supabase’s hosted PostgreSQL and Edge Functions give us version control, user management, and lightning-fast reads/writes out of the box.
Snapdeck, the makerSep 2026 ↗
Supabase is CatDoes' backend. We use their database, auth, storage, and real-time features. A platform like CatDoes requires a stable and scalable backend, and Supabase is providing that!
CatDoes, the makerSep 2026 ↗
Supabase makes backend work a breeze with instant APIs and real-time sync. We skip building auth and complex DB setups, letting us launch features faster and focus on what really matters.

Loved and watch-outs

Themes that recur in makers' words and Hacker News comments, each linked to what it summarises.

Clerk
Most loved
  • Sign-up, sign-in, sessions and social login get wired in an afternoon instead of a sprint. PHPH 2
  • Organizations, roles and billing come built in, covering multi-tenant B2B apps without custom identity work. PHPH 2
  • Prebuilt UI components, including profile and settings pages, look polished out of the box. PH
Watch-outs
  • Outsourcing auth means a Clerk outage or account problem locks your users out, and the dependency is hard to reverse. HNHN 2HN 3HN 4
  • Costs climb with SSO, MFA, passkeys and branding removal, and some switched to cheaper open-source options. HNHN 2HN 3HN 4
On Product Hunt: 5.0★, 112 reviews · mentioned most: easy integration, comprehensive solution, free tier
Supabase
Most loved
  • One project covers Postgres, auth, storage and realtime, so a solo founder ships without stitching vendors or hiring a backend team. PHPH 2PH 3PH 4
  • It is real Postgres with SQL, row-level security and pgvector rather than a proprietary store. PHPH 2PH 3PH 4
  • Open source and self-hostable, which reduces vendor lock-in. PHPH 2HNPH 3
Watch-outs
  • Row-level security policies are hard to get right, so many apps end up exposing data publicly. HNHN 2HN 3HN 4
  • Reliability has been shaky for some, and it is not really built for self-hosting in practice. HN
  • Per-project billing adds up for developers running many small side projects. HN
