Is Supabase still worth recommending?

Answers are split. Some founders report no problems and value the free tier, auth and open source base. Others describe billing surprises on idle projects, regret over rewriting a commercial app on it, and intermittent outages serious enough to force a move. Several say it works well for validating an idea and gets harder to justify once pricing grows with usage.

Are row level security mistakes a real risk?

Several developers treat this as the main hazard. One left a table publicly readable over a weekend after forgetting to switch the policy on. Another dislikes the pattern of letting browsers query data directly and warns that a single misconfigured rule can expose everything. If you choose this route, plan to audit the policies on every table.

Should you move from Supabase to Convex or plain Postgres?

People who moved to Convex say it replaced a shaky realtime setup and gave them a full backend framework. One developer tried it and hit limits fast, and another saw a short production stall on the free plan. Those leaving for plain Postgres cite control and predictable pricing, and some keep Neon or Turso in the mix for low cost early projects.

Neon

5 mentions: 2 positive, 0 mixed, 0 negative, 3 no opinion

Founders use it as managed Postgres, and one picked it because an idle project costs nothing.

Positive: Uses it for Postgres during the dev and startup phase and sees it as worthwhile under load. r/startups thread, Oct 2026

Positive: Runs most projects on it now. r/SaaS thread, Jun 2026

Firebase

3 mentions: 0 positive, 1 mixed, 0 negative, 2 no opinion

Developers use its auth for simple sign in, and one reports having to build roles by hand.

Mixed: Works well enough until you need roles, since the lack of an organisation concept means writing permissions by hand. r/SaaS thread, Sep 2026

Supabase

33 mentions: 4 positive, 5 mixed, 9 negative, 15 no opinion

Builders like how fast it gets a project running, while the complaints center on billing surprises, row level security mistakes and outages.

Positive: Names it as the fallback at larger scale if Neon stops fitting. r/startups thread, Oct 2026
Negative: Was billed for idle projects after upgrading, could not get a refund or real escalation, and plans to leave. r/SaaS thread, Nov 2026
Mixed: Says it got a project moving fast, then found only the database was in use and bills grew hard to predict. r/indiehackers thread, Jul 2026
Positive: Runs Postgres and auth on it for a sizeable audience and reports it working well at low cost. r/SaaS thread, Sep 2026
Negative: Was caught out by egress charges and prefers a VPS with managed backups. r/SaaS thread, Oct 2026

Frequently asked questions

Which backend or auth platform does Reddit recommend most?

Convex had the strongest showing in the 37 posts and comments we read from 3 subreddits, with 3 positive mentions, 0 mixed and 2 negative, out of 5 in all, as of November 2026. These counts reflect one sample of Reddit opinion, so weigh them alongside your own needs.

Can Supabase handle my complete backend?

Commenters in these threads say it covers database, auth, storage and functions for a small product, and that it suits an early launch well. Several warn that costs and security setup need attention as you grow, especially row level security on each table and usage based billing across projects.

Does anyone pay for Supabase, and are the paid features worth it?

One founder found the upgrade added charges for idle projects and could not get them refunded, so they plan to leave. Another says the per project price adds up across client environments. Those who stay describe it as a fast way to start, so count your active projects before upgrading.

What do founders pick for SaaS login and auth?

Developers in the threads named Firebase Auth, Supabase Auth, Clerk, Auth0 and Auth.js. One Firebase user said it works until you need roles and organisations, then you end up writing permission logic yourself. One team skipped providers entirely to carry tenant and role data in each request.
