A terminal-first ADE for the coding agents you already use

Open your projects, run agents like Claude Code, Codex and opencode in real terminals, and keep git — worktrees, diffs and pull requests — in view without leaving the window.

Install Source on GitHub

curl -fsSL https://raw.githubusercontent.com/omartelo/lich/main/install.sh | sh

Linux one-liner — detects your distro, verifies the checksum, installs the native package.

Four Claude Code sessions side by side on one wall, each in its own git worktree — the sidebar lists them with their branch and diff badge, and the footer shows the model, the plan and the branch

Why lich

A single static Go binary that opens its UI in its own embedded Chromium (CEF) on Linux, Windows and Apple Silicon. No Electron, no webview toolkit.

Run the agent you already have

Claude Code, Codex, opencode, oh-my-pi and Crush are first-class — point lich at each binary once, pick the default, or choose per session.

Keep a real terminal

Real PTY-backed shells rendered on the GPU — searchable scrollback that survives a page reload. The footer follows cd and names the branch — and, for a Claude session, the model and the context window in use.

Put one session to work for another

Hand a task to another card and its own agent writes the answer back, whatever runs in either end — through MCP tools handed at spawn, or the lich command from any shell, --json included.

Branch off a worktree without the setup

Spin one up from any base branch, seeded with your gitignored .env* files, a dev-server port of its own and your per-project setup script — before the agent starts.

Review the diff where you read it

A diff dock beside a live file tree. Right-click a selection to comment against those lines; the batch lands in the session as one prompt, unsent.

Ship the pull request from here

List them with GitHub's own qualifiers, check one out into its own worktree, review it inline and merge it — with the methods the base branch actually accepts.

A look around

The review dock with two comments written against lines of the diff — Comments written on the diff, handed to the session as one prompt.

The pull request list with author, age and check status, narrowed by a filter box — The repository's pull requests, filtered by GitHub's own qualifiers.

A pending review comment sitting inline under the lines it is about — A review written on the diff itself — each comment pending until you submit them together.

Settings, Appearance: bundled themes beside an imported pack showing its repository and version — A theme pack installed from a git repository, updated in place.

Install

Manual per-distro packages, the Linux tarball and the Windows portable zip live in INSTALL.md.

Everything runs on your machine

No account, no sign-in, no telemetry. The backend is a token-authenticated loopback listener, and nothing leaves localhost except the update check — a version ping to GitHub Releases. Your workspace lives in SQLite under your config directory.
