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).

Scott Lanoue - CoMail
This week we're joined by Scott Lanoue, the creator of CoMail, a cooperative email service built on the AT Protocol.Getting a self-hosted mail server to actually land in the inbox is a months-long slog of warming IPs and building domain reputation, so CoMail pools that reputation across everyone sending through a shared relay. We talk about how atproto identity lets CoMail vend out trust instead of spam scores, what it means to store your mail in your own PDS with spaces, and why a co-op might be a better shape than a startup for a protocol with no moats. https://comail.at/ https://scottlanoue.com/ https://bsky.app/profile/scottlanoue.com https://tangled.org/scottlanoue.com/atmosphere-mail
