Redlamp: free and open-source Lightroom alternative, full feature parity, macOS native

I've been quietly working on Redlamp – a free and open-source alternative to Adobe Lightroom, aiming for full feature parity, no fluff, and performance-conscious.

I'm fully aware just how ambitious an undertaking like this is, but in 2026 with the advances of frontier models, this is genuinely attainable. But not without help and a community to back it.

This is where you can help – there's already a huge amount done, but testing and user feedback are the main priorities right now. And this is where you come in – download it, test drive it, tell me what's not working, what's broken, what's half-baked. Anything and everything (just keep it civil, please!).

Head out to https://redlamp.app, download it and give it a test drive.

Redlamp is still in pre-alpha stage so expect rough edges.

Thanks for reading!
