Open Source — Self-host or try hosted

A lightweight client
for Gmail.

Full-featured webmail comes with calendar sidebars, embedded chat, and hundreds of megabytes of JavaScript. LowFat strips all that away and keeps just the core — read, write, search, done. An open-source, server-rendered client that stays out of your way.

Why LowFat

Less is more. By design.

No calendar widget. No Meet popup. No Chat sidebar. Just the email features you actually use, running on minimal code.

⚡

Server-Side Rendered

HTML is rendered on Cloudflare's edge network. Your browser receives lean, ready-to-display pages instead of megabytes of JS.

🧳

Low Memory Footprint

No embedded Meet, no bundled Chat, no add-on panels. Fewer features means far less code in your browser. Leave it open all day.

🌏

Edge-Deployed

Runs on Cloudflare Workers across 300+ cities worldwide. Sub-50ms response times no matter where you are.

🔒

Privacy First

Your credentials stay encrypted in secure KV storage. No analytics, no tracking, no ads. Zero data harvesting.

🎨

Dark Mode

Automatic dark mode that follows your system preference. Easy on the eyes, day and night.

📱

Responsive
