Windows uses WebView2. Linux packages are built on Ubuntu 22.04 and require a compatible host with WebKitGTK 4.1; AppImage compatibility varies by distribution. The Debian package is about 2.3 MB before system dependencies; the portable AppImage is about 80 MB. See the README for setup and limitations.
Preview status
All automated checks and installer builds passed on GitHub, including native tests on Windows, macOS, and Linux and editor tests in Chromium and WebKit. A native Mac launch was also verified locally. This is an early preview; manual installer testing across the supported operating systems remains a release-hardening task.
The packages are not trusted-publisher signed or notarized. Mac packages use ad-hoc signing, and Windows packages are unsigned, so downloaded installers may trigger OS security prompts. Build from source if you prefer.
This version edits one UTF-8 file at a time, up to 5 MB. OS “Open with” associations, folder workspaces, and tabs are not yet included. Raw HTML is shown as text and remote images are blocked by default. The app does not execute document code.
