Instant

Instant builds a real-time backend platform designed for the AI era of app development. The team started with a deep research essay on database architecture in 2021, open-sourced the platform in 2024 to 1,000+ Hacker News upvotes, and has since grown to handle 10,000+ concurrent connections and 1,000+ queries per second in production. Backed by Y Combinator and SV Angel, Instant combines a triple-store database, declarative permissions, built-in auth, and file storage into a single coherent package that modern LLMs can use natively.
