Review Bun?

Reviewers mostly praise Bun for cutting JavaScript tooling down to one fast runtime. Makers of OpenCutAI say install times fell sharply and hot reloads stayed near instant in a large monorepo, while the makers of OpenFlags credit its built-in runtime, build tools, and SQLite support for leaner infrastructure. The makers of IgnitionRAG also highlight native TypeScript, testing, env handling, and faster cold starts. There is no meaningful critical feedback here, so the picture is narrowly positive and founder-led.
