About Offrun

Offrun is an innovative Mac application designed specifically for developers who want to leverage multiple AI coding agents simultaneously while maintaining a seamless and efficient workflow. Unlike typical AI coding tools that require API keys and cloud-based services, Offrun operates entirely on your local Mac environment, ensuring complete privacy and security by running all AI processes locally. It orchestrates multiple popular AI coding agents—such as Claude Code and Codex—by isolating each one within its own git worktree, thereby preventing any conflict between concurrent development tasks.

One of Offrun's standout features is its peer review system, where a secondary AI agent reviews code diffs and provides thoughtful feedback before any code is merged, enhancing code quality without automating merges prematurely. It also stores project memory as plain files, including coding conventions, plans, and dead ends, which agents use to recall prior work and context for more coherent assistance. The rich chat interface supports various content formats and includes an on-device dictation system, enabling private and accurate voice commands without sending data off your machine. Overall, Offrun enhances developer productivity by integrating powerful AI coding support directly into local development workflows with a strong emphasis on privacy and ease of use.

Use Cases

A software engineer concurrently debugging multiple modules can assign separate AI agents to distinct git worktrees, enabling simultaneous bug fixes without merge conflicts.
A development team utilizes Offrun's peer review system where a second AI agent critiques draft code before human review, improving code quality and reducing manual review load.
A freelance developer managing API usage across multiple AI agent accounts avoids service interruptions by seamlessly switching between accounts when limits are reached, maintaining continuous productivity.
A developer working on long-term projects benefits from Offrun’s project memory feature, which preserves coding conventions and previous failed attempts, allowing AI agents to provide consistent and informed suggestions over time.
A privacy-conscious developer uses Offrun's local execution and on-device speech transcription to securely dictate code instructions without exposing sensitive project data to external servers.
A startup integrates Offrun into their CLI-based workflow to run multiple AI coding assistants side-by-side without altering existing toolchains or needing API key management.
A developer experimenting with refactoring and feature development runs agents independently to work on separate branches concurrently, merging changes manually when ready.

Key Features

Runs multiple AI coding agents in parallel with isolated git worktrees
Local execution without API keys to ensure privacy and security
Multiple agent accounts to handle usage limits without interruption
AI-assisted code review by a second agent before changes merge
Project memory storage for conventions, plans, and failed attempts saved as plain files

Pricing

Offrun is offered as a free application with all primary features included at no cost. There are no charges for unlimited agents, projects, on-device dictation, or scheduling. Users must bring their own AI agent subscriptions (e.g., Claude, Codex) for which Offrun acts as a management and orchestration layer. The tool itself does not charge subscription fees or usage fees, and there are no seat-count limitations or payment requirements for core functionality. This free model enables developers to leverage their existing AI service subscriptions while benefiting from Offrun’s enhanced local features and workspace management.

Pros & Cons

Pros

+ Runs multiple AI coding agents in parallel with isolated git worktrees to prevent task conflicts and streamline concurrent development.
+ Operates fully locally on Mac, so no API keys are required and code and prompts never leave the developer's machine, enhancing privacy and security.
+ Supports multiple agent accounts to bypass API usage limits seamlessly without interrupting coding sessions.
+ Features a built-in peer review system by a secondary AI agent that reviews code diffs before any merges, improving code quality without unwanted automation.
+ Includes project memory stored as plain files that capture coding conventions, plans, and dead ends for contextual continuity across sessions.
+ Rich chat interface supports displaying code diffs, markdown, tables, images, and more for an enhanced AI conversation experience.
+ On-device dictation offers private voice input without sending data to external servers, specifically optimized for Apple Silicon and macOS 26.

Cons

- Currently available only for Mac, limiting access for developers on Windows or Linux platforms.
- Requires users to have existing subscriptions/accounts for AI coding agents like Claude or Codex, which may entail separate costs.
- The complexity of managing multiple agents and accounts may introduce a learning curve for developers unfamiliar with git worktrees or AI agent orchestration.
- The peer review is AI-based and does not eliminate the need for human code review, so developers must still oversee merges and final approval.

Frequently Asked Questions

Does Offrun require internet access to function?

While Offrun runs AI agents locally on your Mac, you still need internet access for the AI providers (like Claude or Codex) to process your prompts, as those services operate remotely. However, Offrun itself does not send or store your code on its own servers.

Can I use Offrun on operating systems other than macOS?

Offrun is currently designed exclusively for Mac running Apple Silicon and macOS 26 or later, leveraging macOS-specific features like on-device dictation. There is no official support for Windows or Linux at this time.

Do I need API keys to use AI agents with Offrun?

No, Offrun does not require you to enter API keys. You sign into your AI coding agent accounts directly within Offrun, and the processes run under your credentials locally, ensuring your keys remain private and are not handled by Offrun servers.

How does Offrun handle multiple AI accounts and usage limits?

Offrun allows you to connect multiple AI agent accounts. If one account hits its usage limit, Offrun automatically switches the conversation to another logged-in account so you can continue working seamlessly without interruption.

Is the AI code review automatic or manual?

The AI code review agent reviews your code diffs and gives feedback within the chat interface but does not merge any changes automatically. You retain manual control over merges ensuring full oversight of code integration.

What kind of project memory does Offrun maintain?

Offrun stores conventions, plans, and dead-end attempts as plain markdown or text files within your project folder. This enables AI agents to recall prior work contextually, improving accuracy and reducing repetition over multiple sessions.
