Paste your SQL schema and slow query—no DB credentials needed. IndexDoctor spins up an in-memory Postgres sandbox on Google Cloud Run, compares real Before/After EXPLAIN plans, applies the ESR rule, and outputs Raw SQL, Drizzle ORM, and Prisma indexes.

How did you use Cloud Run for this launch?

Maker

IndexDoctor is packaged and deployed directly on Google Cloud Run as a unified, stateless Node.js 22 + Hono container serving both our React SPA and our diagnostic API. Instead of connecting to an external database or relying purely on LLM guesses, each request spins up an isolated, ephemeral in-memory PostgreSQL engine (PGlite WASM) directly inside the Cloud Run container's memory space. Cloud Run executes the user's DDL, simulates production table statistics, captures the baseline EXPLAIN (FORMAT JSON) plan, calls Gemini model to synthesize an ESR-optimized index, applies the CREATE INDEX migration inside the container sandbox, and re-runs EXPLAIN to mathematically verify the planner cost reduction before tearing down the sandbox.
