For Claude Code vibe coding, the most convenient and popular options are:
Supabase
This is the go-to choice for most vibe coders. It gives you a full Postgres database with instant REST and GraphQL APIs, auth, storage, and real-time subscriptions out of the box. The free tier is generous, and Claude can easily generate the SQL schemas and client code. You just create a project, grab your connection string, and you’re off.
SQLite (local/embedded)
For quick prototypes or tools that don’t need a server, SQLite is unbeatable. No setup required — just a file. Claude Code can spin up a working database in seconds with better-sqlite3 or Drizzle ORM. Great for CLI tools, local apps, or anything you want to ship as a single binary.
Turso (libSQL)
If you want SQLite but with edge deployment and sync capabilities, Turso is gaining traction. It’s essentially hosted SQLite with a generous free tier and works well for read-heavy apps that need low latency globally.
Neon
Serverless Postgres that scales to zero — you only pay when you use it. Nice if you prefer Postgres semantics but want the convenience of serverless. The branching feature is handy for testing schema changes.
Cloudflare D1
If you’re already deploying to Cloudflare Workers, D1 integrates seamlessly. SQLite at the edge with automatic replication.
The vibe coder default is Supabase — it has the best balance of power, convenience, and Claude-friendliness. You can describe what you want in plain English, Claude generates the migrations and client code, and Supabase handles auth/storage/realtime without extra configuration.
