Flue is a TypeScript framework for building the next generation of agents | Hacker News

Flue, a new TypeScript framework for AI agents, was introduced on Hacker News.

Discussion quickly focused on its missing tests, maturity, and how it differs from Mastra, pi.dev, and Cloudflare-style tooling.

Some commenters questioned whether agent apps need framework APIs at all, arguing prompts and generated code may be a better fit.

The thread reflects both momentum around agent-building frameworks and skepticism in a crowded AI tooling market.
