🌙 Hey Product Hunt — Ethan here, builder of LunarFS! The origin story is pretty simple: I was watching Theo's video where he ran through a list of things he wished existed but didn't have time to build — and "Dropbox for devs" was one of them. That hit home immediately, because I was hitting the exact same wall. The problem: I work in parallel across a lot of environments — spinning up new workspaces, switching contexts, running multiple AI coding agents at once. Every time, I'd either wait forever for a full clone/copy, or lose track of files between environments. It was death by a thousand cuts. So I built LunarFS: ⚡ Fork a full workspace in milliseconds, not seconds — lunar ws fork forked the entire Linux kernel (94k+ files) in 13ms vs. 7.4s for git worktree add, with zero bytes copied 🧬 Content-addressed (BLAKE3) — files are stored once and hydrate lazily on first read, so spinning up a new workspace is basically instant 🔄 Cross-machine sync — push/pull workspaces between machines without a full re-clone 🤖 Built with AI agent workflows in mind — perfect for running multiple coding agents in parallel without juggling clones Why open source: This solves a problem I know other devs and agent-builders have, not just me. Engine is AGPL-3.0, clients are Apache-2.0 — so you can build on top of it freely. Self-hosting is free forever. If you'd rather not run your own store, we're also building a hosted version — you can join the waitlist at lunarfs.com 🚀 Huge thanks to Theo for the spark on this one, and to everyone who tested early builds with me 🙏 Would love your feedback, bug reports, and feature requests — and if you've been fighting the same parallel-workspace pain, I'd love to hear how you're solving it today! PS — if anyone knows Theo, slide him this link lol. Been a fan of his for years, would mean a lot if this ever crossed his desk 😄
