A database proxy that captures every write in a private in-memory delta — leaving your source database exactly as you found it.
Reads pass through to your real database in real time. Writes are captured in VirtualDB's private delta and never forwarded to the source. The moment a VirtualDB instance exits, the delta is gone.
Every developer, CI run, or AI agent runs their own VirtualDB instance with its own private delta. No shared schemas to migrate, no test databases to provision, no teardown scripts to maintain.
VirtualDB sits in front of your existing database server. Your data doesn't move, your schema doesn't change, and your application connection string changes by exactly one hostname.
VirtualDB speaks the native wire protocol of your database. Any client, ORM, or query builder that already works with your database works with VirtualDB — no SDK, no code changes.
Plugins are out-of-process executables that communicate over JSON-RPC 2.0 on Unix sockets. Intercept, inspect, or modify queries at well-defined pipeline points without touching VirtualDB's core.
The MySQL driver is the first implementation and is available today as a pre-built Linux/amd64 binary. Postgres and additional drivers are on the roadmap.
