Bitig is a terminal emulator built from scratch for Windows 11 on native ConPTY and xterm.js. Fully local, zero telemetry, no account — and it does the reading of your output for you: ports, stack traces, secrets, history.
winget install Bitig.Bitig
Win+~
AI Ctrl+I
Bitig exists to close the gaps left by Windows Terminal on one side and cloud-account terminals on the other.
No cloud dependency, no telemetry, no sign-in. Every setting, theme, snippet and history entry lives as plain JSON under %APPDATA%/Bitig/.
Real Windows 11 ConPTY sessions through node-pty, rendered by xterm.js with GPU acceleration — a rendering pipeline that stays smooth under a firehose of output.
Every feature is one chord away, every chord is rebindable, and a command palette covers the rest. Splits, tabs and the Quake HUD keep your hands where they are.
The terminal reads its own output: clickable port badges, stack traces that jump into your editor, masked secrets, parametric runbooks and a local AI assistant.
Six things you feel within the first ten minutes of using Bitig as your daily shell.
The most likely command appears as ghost text behind your cursor as you type. Press Tab to take all of it, Ctrl+→ to take it word by word.
package.json scripts, Makefile targets and the current folder.Stop scrolling back to find the URL your dev server printed.
:3000 and :5173 are detected in the output stream and pinned to the status bar as clickable badges.file:line reference in an error opens at that exact line in VS Code, Cursor or Windsurf.API keys, JWTs and AWS or GitHub credentials are masked on screen the moment they are printed, so a screen share or a stream never leaks them.
Ctrl+I opens an assistant backed by Ollama (Llama 3, Mistral, Qwen) or your own OpenAI / Anthropic key. It drafts commands and explains stack traces; nothing runs until you press Enter.
Ctrl+Shift+B turns a multi-step sequence into a parametric runbook with typed inputs and a live preview. Plain JSON, easy to share with the team.
Infinitely nested splits, each with its own shell and working directory. Win+~ drops a Quake console from the top edge; Alt+Shift+I types into every pane at once.
Every panel is designed to be read at a glance and dismissed with one key.
Tabs, split panes, port badges and the live status bar.
Ghost text for npm scripts, git and directory paths.
Fuzzy search over actions, tabs, profiles and themes.
Port sniffer, smart links and Secret Shield together.
Local models through Ollama, or bring your own key.
Parametric, local, shareable as plain JSON.
Horizontal and vertical splits with draggable dividers.
Built-in palettes plus any JSON theme you drop in.
Manifest-based extensions inside a Node vm sandbox.
Measured on the three things that made it worth building: privacy, engine and developer tooling.
