Managing a remote server usually means juggling a terminal, an SFTP client, a text editor, and a pile of ssh -L commands. Termlet puts them in one lightweight native window: connect once, then browse files, edit them in place, and tunnel ports without leaving the app.
Built with Wails v2 (Go) and React 19 + TypeScript, so it ships as a small native binary instead of an Electron bundle.
- SSH terminal and profiles: save servers, use passwords, private keys (with passphrases), or your SSH agent. Host keys are verified, with a warning when a key changes.
- Multi-tab remote terminal: true line-based stream emulator with multi-tab concurrency, multi-line command continuation (
\& Shift+Enter), tab renaming, tab duplication, and draggable drawer resizing. - SFTP file browser: browse, create, rename, delete, and upload files on the remote host with bi-directional terminal CWD sync.
- Remote code editor: CodeMirror 6 with syntax highlighting, multiple tabs, 14 themes, and Ctrl+S to save straight to the server. Binary files are detected and not opened.
- Local port forwarding (
ssh -L): create, start, and stop tunnels from a dedicated view. Forwards are saved with the profile, with one-click "open in browser" and presets for common services (HTTP, Vite, PostgreSQL, MySQL, Redis, Traefik). - Auto-update: checks GitHub Releases and installs updates in place (
.deb,.rpm, Windows installer, or portable binary). - Polished UI: frameless window, resizable sidebar and terminal drawer, light and dark themes, and readable error messages with troubleshooting hints.
