The terminal-first IDE. Built in Rust. GPU-rendered. Fast AF.
Your agents live in tabs. Your tabs are isolated worlds. Drag one out and it's a window.
No Electron. No web views pretending to be an app. One Metal drawable, all the way down.
Important
twarp is an independent community fork of the open-source Warp terminal. It is not affiliated with, endorsed by, or supported by Warp (warp.dev). "Warp" is a trademark of its respective owner; twarp uses the name only to describe its origin as a fork. Do not report twarp bugs upstream — file issues here. For the official product, go to warp.dev.
Every IDE bolted an AI into a sidebar. twarp did the opposite: it took the fastest terminal codebase ever open-sourced, ripped the built-in AI out by the roots, and rebuilt the whole app around the agent you already pay for — the claude CLI, running locally, on your subscription.
Type claude in any tab. It doesn't scroll by as text — it opens as a full native chat pane: streaming responses, tool cards, diffs, plan rendering, permission prompts, session resume after a crash. The terminal is the IDE. The agent is the workflow. And the whole thing renders like a video game because it is rendered like a video game.
🧊 Tab isolation is the whole game. Every tab is a sealed world: its own shell, its own working directory, its own Claude session, its own color. Red tab = prod. Green tab = local. Purple tab = the agent refactoring a worktree while you work in the next tab over. Run multiple Claude sessions side by side — one per tab, one per pane, zero crosstalk. This is what multi-agent work actually looks like when the UI was built for it instead of retrofitted.
🪟 Drag a tab out — it's a window. Chrome-style tabs, for real: grab one, tear it off, drop it on your other monitor. Drag it back into another window's tab strip. Your agent session, your shell, your scrollback — all of it moves with the tab. Try that in a terminal multiplexer.
🦀 Rust + Metal, no Electron tax. VS Code is a browser wearing a trench coat. cmux is web tech in a native frame. twarp is a Cargo workspace of 60+ crates drawing every pixel through its own GPU UI framework — text rendering, scrolling, and input latency in the same class as Zed, except the terminal is the first-class citizen, not a panel under the editor.
⌨️ Terminal-first, not terminal-included. Zed and VS Code are editors that ship a terminal in the basement. twarp inverts it: you live in the shell, and the IDE surfaces come to you — a VS Code-style Open Changes panel (stage hunks, commit, push without leaving the terminal), markdown rendered in place, and a file editor with LSP go-to-definition rolling out now.
🕶️ Your agent can see what you see. The built-in browser pane exposes its live DOM, console, and network to your Claude session over MCP — the agent debugs the exact tab you're looking at, not a headless clone. And the computer-control overlay lets a session drive the whole Mac in a screenshot → action loop, with a glow border so you always know when it's live.
🔒 No middleman on your AI. No LLM client in the app. No AI billing. No cloud sync of your conversations. twarp renders your local claude process — your keys, your subscription, your machine. The fork's first act was deleting every line that phoned an LLM from inside the terminal.
- 🤖 Claude Code pane — native streaming chat UI over the local
claudeCLI, with raw-CLI toggle, MCP server viewer, and post-crash session resume - 🌐 Agent-debuggable browser — WKWebView pane wired to your Claude session via MCP
- 🖱️ Computer control — Claude sees and drives the Mac, with visible capture indicator
- 🎨 Tab colors on keystrokes —
⌘⌥1..8, instant visual context isolation - 🔀 Chrome-style tab tear-off — tabs → windows → tabs, drag both ways
- 📝 Open Changes panel — VS Code-grade git staging, diffs, commit & push, in-terminal
- ⚡ Custom command shortcuts — bind one keystroke to "new tab, type
claude, enter, run my slash command" - 📄 Markdown rendered by default —
.mdfiles display, not dump - 🍎 macOS-native feel — macOS-style sidebar, theme-following panels, all emulated in the GPU framework
Shipping next: the full IDE pivot — file editor with LSP go-to-definition, git blame, project-wide search & replace, and a multi-provider agent settings page. Live status: roadmap/ROADMAP.md.

- Tracks
warpdotdev/warpby selective cherry-pick — perf, rendering, and fixes come across; AI commits are skipped. Forked fromwarpdotdev/warp@d0f045c0(2026-04-28). - twarp doesn't use Warp's brand assets, doesn't touch Warp's cloud AI services, and doesn't misrepresent itself as Warp.

Inherited from Warp unchanged: the UI framework crates (twarpui_core, twarpui) are MIT; everything else is AGPL v3. The complete corresponding source for every twarp build is this repository.
twarp exists because the Warp team built an outrageously good terminal and open-sourced it — the Rust codebase, the custom Metal UI framework, the terminal emulation are theirs. Shout-outs down the stack: Tokio, Alacritty, NuShell, Hyper, Smol.
