A quiet place for your email.
A minimal, fast desktop client for Gmail. No clutter. No ads. No noise. Just your inbox, cached locally, ready the moment you open it.
v1.0.0 — Free and open source under MIT
Every decision was made to remove friction. No tabs. No chat widgets. No promotions sidebar.
Your inbox syncs to a local SQLite database. Open the app — your emails are already there. No spinners. No waiting.
Emails render in a centered 680px column with generous line height and system serif. Finally, an email client that respects the craft of reading.
Radius only reads your inbox. No send, no delete, no archive. Your OAuth scope is minimal. Your trust is maximal.
Background incremental sync via Gmail's history API. New emails appear without a manual refresh. The cache stays warm.
OAuth tokens live in your system keychain, not a config file. HTML email bodies are sanitized before they ever reach the renderer.
Virtualized lists handle 10,000+ emails without breaking a sweat. Built with @tanstack/react-virtual and disciplined rendering.
Three steps from install to inbox. No configuration files. No server to run.
One-click OAuth with PKCE. We request read-only access. You approve. That's it.
Radius fetches your inbox and stores it locally. A progress bar shows the way. For a thousand emails, this takes under a minute.
From now on, Radius opens instantly. Background sync keeps you current. No waiting. No loading states. Just email.
“Speed is the feature. Silence is the interface.”
We built Radius because existing email clients treat your attention as inventory to be sold. Ads in the sidebar. Promotions in your primary tab. Chat widgets sliding over your draft. Every pixel is a negotiation.
Radius does less, better. One account. One inbox. One beautiful reader. If you need a power tool, this isn't it. If you need a quiet place to read your email — welcome.
Radius is MIT licensed. The entire stack — from the sync engine to the renderer — is plain TypeScript. No hidden binaries. No telemetry. No dependencies you can't audit.
