Offrun
Manage every coding agent from one workspace
About Offrun
Offrun is a free macOS app for developers who run several AI coding agents at once. It puts Claude Code, Codex, AGY (Google's Antigravity CLI), Grok Build and Muse Code side by side in one workspace and shows which agent is working, which one is waiting on you, and how much of each account's session and weekly limit is left. It addresses a specific problem of agent-heavy work: once you have three or four agents going in different terminals, it becomes hard to see who needs an answer, who is stepping on whose files, and when a subscription is about to run out.
Offrun does not replace the agents. It runs the CLIs you already have on your Mac, signed in as you, so prompts and code go straight from your machine to Anthropic, OpenAI, Google or xAI on your own login, and Offrun never handles your keys or passwords. Chats, memory and worktrees are stored as folders inside your repository. Offrun is made by Founderly, Inc., requires macOS 14 or later, and its pricing page states that every feature is free and unlimited with no card; you bring your own agent subscriptions.
- •Install Offrun and drag it to Applications.
- •Connect your coding harness accounts under Settings, then Agents. You can add more than one account per harness, for example a work and a personal Claude login.
- •Start an agent by picking a project and giving it a task. Each agent gets its own git worktree, so two agents on the same repository never touch the same files.
- •Watch the Home view for agents that are working, waiting on you or have an unread answer, review the diffs and previews beside each chat, and merge branches on your own schedule.
- •Parallel agents, one worktree each - Every agent in a project works on its own branch and worktree, so a refactor and a bug fix can run at the same time without conflicts.
- •Usage and limits view - Shows each connected account's session and weekly usage and when it resets, across Claude, Codex and Gemini-based agents.
- •Project memory - Keeps repo-wide conventions plus each agent's plan and recorded dead ends as plain files that agents read at the start and write back to, so later sessions know what earlier ones tried.
- •Preview panel - Shows diffs with line numbers, rendered markdown and tables, flowcharts, images, PDFs and a small browser beside the conversation that produced them.
- •Peer review - Lets one agent review another agent's work before you merge it.
- •On-device dictation - Hold a key and speak a prompt; transcription runs on the Mac, keeps code identifiers spelled correctly, and nothing is recorded or uploaded (needs Apple silicon and macOS 26).
Offrun is for developers who already pay for one or more coding agent subscriptions and want to run them in parallel on a Mac without juggling terminals. It suits solo builders who split work across Claude Code and Codex, people with several accounts for the same harness, and small teams who want agents isolated in worktrees with memory kept in the repo. Because Offrun has no server in the prompt path, it also fits developers who do not want a third party to see their code or credentials.
