ReadySet

Readyset is a realtime SQL caching engine for Postgres and MySQL. It sits between applications and the database as a wire-compatible proxy, automatically caching the results of costly SELECT queries and keeping them up to date from the database replication stream with no application code changes or manual invalidation. Written in Rust and available as open source (BSL 1.1), a self-managed Private deployment, and a fully managed Readyset Cloud offering on AWS, it also ships Readyset AI — an MCP server plus the rdst diagnostics CLI — so AI assistants and developers can inspect caches, analyze slow queries, and deploy caches directly. Backed by Amplify Partners and Index Ventures.

ReadySet is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, Database, Caching, and SQL.

ReadySet’s developer surface includes documentation, getting-started guide, engineering blog, pricing, signup flow, support, changelog, and 13 more developer resources.
