Terax is a lightweight open-source terminal (ADE) built on Tauri 2 + Rust and React 19. A native PTY backend with a WebGL renderer, an agentic AI side-panel that runs against your own keys or fully local models, plus a code editor, file explorer, source control with a git graph, and a web preview pane built in. About 7-8 MB on disk. No telemetry. No account. Latest installers are on the Releases page. Terax auto-updates from there. 1. Open Settings -> AI. 2. Pick a provider and paste your API key. For local inference, point Terax at your LM Studio / MLX / Ollama endpoint. 3. Keys are written to the OS keychain via keyring. They never touch disk or localStorage.

Install
Latest installers are on the Releases page. Terax auto-updates from there.
Windows notes
- On first launch Windows shows "Windows protected your PC" because Terax isn't code-signed yet. Click More info then Run anyway.
- Default shell detection:
pwsh.exe(PowerShell 7+) ->powershell.exe(Windows PowerShell 5.1) ->cmd.exe. - WSL is a first-class workspace environment, not a wrapped subprocess.
Linux notes
- Arch / AUR:
yay -S terax-bin(orparu, etc.). Tracks the latest release. - AppImage: needs FUSE. Without it:
./Terax_*.AppImage --appimage-extract-and-run. On Wayland with rendering glitches, tryWEBKIT_DISABLE_DMABUF_RENDERER=1. Otherwise the.deb/.rpmpackages link against the system GTK stack and tend to be smoother.
Configure AI
- Open Settings -> AI.
- Pick a provider and paste your API key. For local inference, point Terax at your LM Studio / MLX / Ollama endpoint.
- Keys are written to the OS keychain via
keyring. They never touch disk or localStorage.

Recordly
Recordly is your open-source screen recorder and editor for walkthroughs, demos, product videos, and more. Accepting PRs.

MiMo Code
MiMoCode is a terminal-native AI coding assistant. It can read and write code, run commands, manage Git, and use a persistent memory system to keep a deep understanding of your project across sessions while continuously improving itself. MiMo Auto is built in as a free-for-limited-time channel, so you can start with zero configuration. MiMoCode also supports connecting to any mainstream LLM provider API. The first launch guides you through configuration automatically. Supported options:

Kami
Kami (紙, かみ) means paper in Japanese: the surface where a finished idea lands. AI can produce documents better than most humans do manually. The missing piece is not capability but constraint: without a design system, every session drifts into generic gray and inconsistent layouts. Kami fills that gap: one constraint language, nine templates, simple enough for agents to run reliably, strict enough that every output is something you actually want to ship. English and Chinese are first-class; Japanese and Korean work via best-effort CJK paths with visual QA before delivery. Part of a trilogy: Kaku (書く) writes code, Waza (技) drills habits, Kami (紙) delivers documents.
