LowFat is an open-source Gmail client that strips away everything you don't need — no Meet, no Chat, no Tasks sidebar. Just read, write, search, done. Server-rendered on Cloudflare's edge (300+ cities, <50ms). Self-host or use the hosted version.
Hi PH! 👋 I built LowFat Apps because I run 5 Gmail tabs at once for multiple accounts. That alone was eating 1GB+ of memory.
LowFat brought that down to ~300MB. If you're on a MacBook with 8GB RAM, you'll feel the difference immediately.
So I stripped it down to the essentials:
→ Read, write, search — that's it
→ Server-rendered HTML (with preact)
→ ~60MB memory, deployed on Cloudflare Workers
→ Fully open source (MIT)
I still use Gmail when I need filters or advanced settings.
LowFat is for the other 90% of the time.
Happy to answer any questions! 🥬
