Your CLIs run locally. No API keys required.
Each agent's sign-in, step by step, is in the docs.
01 · Parallel agents, a git worktree per task
Make a git worktree for each task and the agents you start in it work on their own branch, so two agents on the same repo never touch the same files. Run a refactor and a bug fix at once and merge them on your own schedule.
02 · Code review by a second agent
Pick a reviewer, and its findings land in the chat while the work is still uncommitted. They wait there until you press Ask agent to fix, which sends them to the agent. Nothing merges on its own.
Runs on your own agent accounts. No second subscription, no bot on your pull requests.
03 · Multiple accounts and usage limits
Point each agent at a different login. When one hits its limit, Offrun moves the chat to a login that still has room and says so. Send your message again and the new login picks up the whole conversation. Out of logins, it offers another agent.
The workspace
Project memory
Offrun keeps repo-wide conventions in one place and each agent's own goal, plan, and dead ends in another. Agents read that context at the start and write back to it as they go, so the fourth session knows what the first one already tried.
Stored as plain files in your project folder. Open them, edit them, commit them.
Preview
What the chat made, diffs with line numbers, rendered markdown and tables, flowcharts, images, PDFs, and a small browser with an address bar, all beside the conversation that produced them.
Dictation
Hold a key and speak your prompt. Offrun transcribes on-device, keeps your identifiers spelled the way your code spells them, and drops clean text wherever your cursor is.
Transcription runs entirely on your Mac. Nothing recorded, nothing uploaded. Needs Apple silicon and macOS 26.
Privacy and security
Dictation turns speech into text on this Mac, and no recording is kept. Choose agy as the speech engine and your voice goes to Google.
Chats, memory and worktrees are folders in your repo, under .offrun and .worktrees. We keep no copy.
Each agent signs in as you, so your code goes from this Mac to Anthropic, OpenAI, Google or xAI. Offrun has no server in that path and never handles your keys.
Pricing
Bring your own agent subscriptions. Everything Offrun adds around them is free.

Every feature, no seats to count, no card.
Your agents can find an email, file a GitHub issue, or post to Slack. You choose which chats use each account.
FAQ
Offrun is a free Mac app for running coding agents side by side. Claude Code, Codex, Antigravity, Grok Build and Muse Code run on the accounts you already have, and git worktrees keep their work apart. You see who is working and who needs you. A second agent can review a diff before you accept it.
No. It runs them. You keep your own accounts and subscriptions, and Offrun gives them somewhere to live together.
Yes. Add each login in Settings, then Agents. When one hits its usage limit, the chat moves to the next and says so, and you send your message again. How multiple accounts work
Yes, at the same time. Give each agent its own git worktree and branch, so they never edit the same files, and one can review the other's diff. Using them together
Yes. When an agent changes files, its answer ends with a card listing each file and its added and removed lines. Open diff shows every file from that turn in a Changes tab beside the chat.
Yes. Offrun runs agy, the Antigravity CLI, signed in with your Google account, next to Claude Code and Codex. Running agents in parallel
Both run agents in git worktrees on your Mac, on your own subscriptions. Conductor builds in pull requests, checks and team features. Offrun is built around several logins per agent for usage limits, a reviewer you pick from your own agent accounts, and Antigravity, Grok Build and Muse Code next to Claude Code and Codex, and it is free. The full comparison
No. Your code goes from your Mac to whichever provider you are signed into, under your own account. Offrun has no server in that path and never handles your keys.
Yes. Turn off Share crash and error reports in Settings, under General. The privacy policy says what a report contains.
Offrun's servers pass it between your Mac and Composio without keeping it. They count actions, not content. For apps you connect with an API key and the MCP apps, Composio, which runs the connections, keeps only a record that an action ran, not what was sent or returned. For apps that use Composio's own sign-in, such as Gmail, Google Calendar, Slack and GitHub, it keeps a log of each action for up to one year, which can include what was sent and returned. Offrun keeps the last 128 actions only while it is open, and forgets them when it quits. The privacy policy has the details.
Only within what you allow. Before you connect an account, you choose what agents can do in it: read, create, change, or delete and cancel, either by kind or action by action. Within those, they act without asking each time, so turn on only what you want them to do. You can change it anytime.
One of your own agent accounts. In the model picker, open the Reviewer tab, turn it on and pick a model.
No. It reads the diff and posts what it found. Every decision after that is yours.
In your project folder, under .offrun. Offrun adds that folder to git's local exclude list, so it never ends up in a commit by accident.
Not by default. Apple's on-device speech engine turns your voice into text on your Mac, with nothing to download. It needs Apple silicon and macOS 26. If agy is installed, Settings, then Dictation, also offers it as the speech engine, and agy sends your voice to Google.
A Mac running macOS 14 Sonoma or later, Apple Silicon or Intel, and at least one agent CLI you already use. Dictation needs Apple silicon and macOS 26.
