devtools.fm: Developer Tools, Open Source, Software Development
Andrew Lisowski, Justin Bennett
A podcast about developer tools and the people who make them. Join us as we embark on a journey to explore modern developer tooling and interview the people who make it possible.
We love talking to the creators front-end frameworks (React, Solid, Svelte, Vue, Angular, etc), JavaScript and TypeScript runtimes (Node, Deno, Bun), Languages (Unison, Elixor, Rust, Zig), web tech (WASM, Web Containers, WebGPU, WebGL), database providers (Turso, Planetscale, Supabase, EdgeDB), and platforms (SST, AWS, Vercel, Netlify, Fly.io).
