Supabase replaces 3 paid apps
One open-source tool, 3 subscriptions it can stand in for. Each pairing below is curated and verified by hand, with the honest catch spelled out. No votes, no pay-to-list.
LizenzApache-2.0
Plattformenyour machine or their cloud
InstallationHosted Supabase project, or the official Docker Compose stack; `supabase start` runs the local stack
DatenRelational data, auth records, and platform metadata live in PostgreSQL; Realtime consumes the Postgres replication stream; object data lives in the configured storage backend with metadata in Postgres; edge-function and migration source stays in project files. Supabase Cloud stores and operates the managed copy.
EinrichtungSelf-hosting is not 'just Postgres': the Compose stack needs many secrets and services, plus SMTP, object storage, TLS, backups, observability, and coordinated upgrades.

Database, functions, realtime, files, and auth in one self-hosted stack; SQL replaces Convex's document model.
the catchSupabase replaces Convex's document/function runtime with PostgreSQL, SQL migrations, row-level security, and separate services, so the application architecture must be rewritten rather than simply moved.
the verdict →all Convex alternatives →
The actual Postgres, Auth, Storage, Realtime, Functions, and API stack; free software, decidedly non-free operations.
the catchThe self-hosted Supabase stack is the real product, but Pro's managed backups, upgrades, observability, support, scaling, and globally operated edge services become the user's problem.
the verdict →all Supabase Pro alternatives →
A local, self-hosted backend with emulators-by-Docker: database, auth, storage, realtime, functions, and APIs.
the catchSupabase is the broadest substitute, but Firebase still has the tighter mobile SDK, offline sync, Analytics, Crashlytics, Cloud Messaging, Remote Config, and Google-service integration.
