Supabase is a strong all-in-one managed Postgres backend, with a listed starting price of $25 and a free plan. It may be a poor fit if you want business logic outside the database, find row-level security hard to manage, or need to rethink storage costs and access. Reddit reports describe those frustrations, but they are individual experiences, not proof every Supabase project will hit the same issues. These five alternatives suit different needs; none is a universal drop-in replacement.
01Why people leave Supabase
RLS can complicate business logic
A commenter on r/startups describes policy rules becoming cumbersome and business logic split between the database and application.
Teams want more backend separation
In one Reddit thread, a team says it added FastAPI and routed database access through its API, leaving Supabase mainly for managed Postgres and auth.
Storage costs and auth lock-in
A Reddit commenter cites storage egress costs and difficulty moving auth without broad password resets; another reports recurring downtime.
02The alternatives, ranked by fit
- TypeScript and real-time
ConvexConvexIf your Supabase project is TypeScript-led and relies on real-time updates, Convex is a candidate for a more integrated backend approach. Its listing targets TypeScript teams and developers who want an integrated backend. The listed entry price is $25 with a free plan, so check usage caps and team pricing before you commit.
Trade-off: Usage caps and team pricing may not suit your expected growth.

$25/mofree plan - Fast app launches
FirebaseFirebaseFirebase fits small teams shipping apps quickly, especially if built-in authentication matters or your team already uses Google Cloud. The listing gives it a $0 starting price with a free plan. It is not presented as a like-for-like managed Postgres alternative, so weigh its database trade-offs before moving an app built around Supabase Postgres.
Trade-off: Usage-based bills and database trade-offs may not fit your app.
7.2/10from
Freefree plan - Self-hosting and toolkit
AppwriteAppwriteAppwrite is worth considering if you want a broad backend toolkit and the option to self-host, rather than keeping your whole backend tied to Supabase's managed setup. Its listing includes a free plan, but gives no starting price. Check whether your project fits the Free resource limits and account for compute costs before switching.
Trade-off: Compute costs and function reliability need checking.
7.1/10from
Freefree plan - Production APIs
XanoXanoXano may fit teams that want to build production apps and APIs with versioned releases and rollback controls. Its listing also calls out AI-assisted API and MCP development. The listed starting price is $85, alongside a free plan, so this is a bigger-price option than a casual Supabase project may justify.
Trade-off: The listed $85 starting price may be hard to justify for a small project.

$85/mofree plan - Live game backends
PlayFabPlayFabPlayFab is the specialized pick here for live games, not a general-purpose Supabase replacement. Its listing highlights managed backend services, built-in LiveOps and analytics, and a $0 starting price with a free plan. It makes most sense when those game-focused services match your needs and your team can forecast usage.
Trade-off: Meter-based billing needs close tracking.

Questions people ask
Which Supabase alternative is closest to an integrated backend?
Convex is listed for developers wanting an integrated backend, with TypeScript and real-time updates as key fits. Firebase and Appwrite also cover broad app-backend needs, but the pricing page do not establish any of these as a feature-for-feature Supabase replacement. Compare the specific services your app uses before moving.
Which alternatives have a free plan?
All five alternatives listed here include a free plan. Firebase and PlayFab list a $0 starting price, Convex $25, Xano $85, and Appwrite gives no starting price. Those figures are not a full cost comparison: Firebase has usage-based bills, PlayFab uses metered billing, and Appwrite calls out compute costs.
Is switching enough to avoid Supabase RLS problems?
Not necessarily. The Reddit complaints describe how access rules and business logic were organized in particular projects; the published information does not show how each alternative handles your app's access model. Map where authorization and business rules live now, then confirm the replacement supports the design you need before migrating.
