fastframe egui on rails

The small crates behind ZapFast, Spotifast, Solco, TonePush and Chat with Work Desktop. Everything a native egui app needs besides its own interface, extracted from apps that already ship it.

Get started

What is fastframe?

GitHub

🔤

Text that looks native

Follows the desktop’s hinting and antialiasing, bundles Inter with tabular figures, and finds installed fonts for every script Inter lacks.

fastframe-text

🎨

Themes people can edit

JSON palettes loaded off the interface thread, eight shared palettes, light and dark pairs that follow the system, and live Omarchy theme following with a reveal from the middle of the window.

fastframe-theme

🪟

Runs without a window

A tray item on every platform, a headless loop around eframe that brings the window back on demand, and windows rescued from off-screen.

fastframe-shell

🔄

Updates that roll back

Self-update from GitHub releases or signed HTTPS feeds, package-manager detection, and a helper that restores the previous version if the new one does not start.

fastframe-update

🌍

Translations built in

gettext catalogs compiled into the binary at build time. No libintl, no PO parsing at run time, English as the fallback.

fastframe-i18n

🔒

Private by default

Logs made for bug reports, with private targets rewritten and panic payloads never written. No telemetry, no hosted services, nothing that phones home.

Native text, in both themes

The font specimen is a real egui window with synthetic text. Try the default interface face or load a validated local font, with the same weight roles and script fallbacks.
