    HAR
    August 2026

    An open-source, agent-agnostic CLI and MCP server that turns repositories into isolated worktrees for multi-agent coding fleets.

    Mission Control
    August 2026

    A local dashboard for real-time observability of every repository, agent slot, run, validation, and artifact across projects.

    Market Position

    OS Factory positions its products as open-source, portable alternatives to vendor-locked agent sandboxes, focusing on 'zero vendor lock-in' and deterministic verification that remains in the user's repository.
