Supabase
An open-source Postgres backend with auth, storage and edge functions.
NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the dev tools job, so this one still earns its $25/mo.
- A named launch, not a vibe named, unlinked
- AI app builders generate schemas but still need somewhere to put them. Anthropic, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 3 of 3 listed replacements have a usable free tier: Firebase, Neon and Convex.
- What the call is worth $300/yr
- $25/mo at the entry paid tier — $300 a year per seat.

The backstory
Supabase is the default backend of the vibe-coding era because every AI builder — Lovable, Bolt, v0 — plugs into it by name. Models write the schema and the queries; the database, the auth sessions and the row-level security policies still have to run somewhere durable.
