Astela

A desktop browser for Windows, macOS and Linux, built on Chromium through Electron. Start-up time and memory stay within budgets that every change is measured against. There is no telemetry, no ads, no sponsored tiles, no news feed and no account.

Download 0.1.0-beta.4

All packages and verification

In place

• Packages for Windows (NSIS installer, MSI), macOS (disk image) and Linux (AppImage, deb, rpm), for x64 and arm64. Every format is installed and started in CI on every change.
• Signed updates with delta downloads. After two failed starts, the previous version comes back on its own. deb and rpm packages update through APT and DNF repositories.
• Policies from the Windows registry, macOS configuration profiles and JSON files on Linux, read before the first window opens.
• Budgets for start-up time, memory, CPU and bundle size, measured against a bare Electron app on all three systems for every change. See performance.
• Security fixes from Electron ship in a patch release within 72 hours, critical ones within 24 hours.

Planned for 0.1.0

• Workspaces, tab bars on any side of the window, tab groups and layout presets.
• Themes with an editor, three density levels, custom shortcuts and a searchable settings page.
• History, bookmarks, downloads, session restore and private windows.

The roadmap lists every milestone; the architecture explains how the browser is built. The source code is on

GitHub under the MPL-2.0.
