Unbiased AI Harness

Coding work is split across terminals, browsers, diffs, and desktop apps. Unbiased AI Harness brings it into one macOS workspace, powered by Pareto, an AI coding model that can read, change, and run code.

Install the latest release

The installer downloads the current release, checks its published SHA-256 checksum when available, installs Unbiased.app in Applications, and clears its one-time quarantine flag.

Prefer to inspect everything first? Read the installer source or use the latest release.

What lands on your Mac

One application contains the interface, the Pareto engine, and the macOS Accessibility bridge. It adds a focused agent workspace without replacing your editor or terminal.

Workspace

Projects, isolated worktrees, source review, a terminal, and a browser in one desktop application.

Pareto

The engine ships in the application bundle. Sign in with a browser or connect an existing Unbiased API key.

Computer control

macOS asks you before granting Accessibility access. You can inspect or revoke that permission in System Settings.

First run

The application is ad-hoc signed rather than Apple-notarized, as documented in the public installer. The installer handles the quarantine flag; a manually downloaded DMG requires right-clicking the app and choosing Open once.

  1. Launch Unbiased from Applications.
  2. Sign in with your browser or provide an Unbiased API key when the app asks.
  3. Grant Accessibility permission only when you want the harness to control another Mac application.

Hand the install to your agent

Ask any web-enabled agent to read the installation runbook. It checks compatibility, explains every system change, asks before installing, and verifies the application afterward.

Open source, end to end

The desktop client, bundled engine, Accessibility bridge, installer, release checksums, contribution rules, and security policies are public.
