Run Claude Code, Codex and Pi side by side on your Mac. Every turn ends in a checkpoint, every command waits for your say, and any session can move to the cloud and back.
Written in Rust on GPUI, the GPU-drawn interface framework behind Zed.
Turns that change code end in a checkpoint you can compare or return to.
On this Mac, in a cloud sandbox, or on a machine you enroll.
Credentials live in macOS Keychain, never inside agent workspaces.
One window for every agent you run, with the plan, the questions, the commands and the saved history in the same place.
Agents lay out a plan before they touch code and stop to ask when the choice is yours. Commands wait for Allow or Deny, right in the thread.
When a turn changes code, GetBranchIt saves the files and the conversation together. Step back through checkpoints, compare any two, and see exactly what changed.
Run a session on this Mac, in a cloud sandbox, or on a Mac or Linux machine you enroll. Move it mid-task: the session brings its files, history and conversation, and only one place writes at a time.
Extensions are written in TypeScript and drawn by the app itself, with the same icons, fonts and theme as everything else. Dock one beside a session, pin a few together, or let one fill the window.
Each one reads the live session through the same typed SDK. Loading your own extensions isn't available yet.
import { defineExtension } from "@getbranchit/extensions";export default defineExtension({ id: "pulse", title: "Pulse", setup(api) { // Runs again whenever the live session changes. api.view((ui, { session }) => { if (session === null) return; ui.row({ gap: 8 }, () => { ui.stat("Turns", String(session.turns.length)); ui.stat("Tool calls", String(session.tools.length)); }); }); },});Delta One and Graphite, each in light and dark, following your Mac.
Seven interface and seven code fonts, from IBM Plex Sans and Inter to Lilex, JetBrains Mono and Paper Mono.
Center the conversation, set its width, and size prose and code separately.
Search on ⌘K, checkpoints on ⌘2, and a shortcut for every panel.
Add MCP servers and secrets once in Settings. Every tool call asks first.
Sign in to Claude, Codex or Pi and pick the model for each session.
The getbranchit CLI gives any agent with a shell the same sessions and checkpoints as the app: 64 commands, JSON in and out, with schemas and dry runs built in.
getbranchit commands; getbranchit sessions --project PROJECT_ID; getbranchit start-agent --input agent.json --wait; getbranchit submit --input turn.json --wait; getbranchit history --input history.json
Each session has exactly one place that can write to it. Moving a session fences the old place out first, so two copies never overwrite each other.
A checkpoint is reported only after it is durably stored. Every operation has an ID, so a retry returns the original result instead of a duplicate.
Agents ask before commands run. Review saved diffs and publish with your normal Git workflow.
Your GitHub access and connection credentials stay in macOS Keychain and trusted services. Agent workspaces never receive them.
We invite developers in small waves, starting with people who already ship with more than one agent.
