What is OpenHarness?
OpenHarness is an open-source platform for building with coding agents. You can use Claude Code, Codex and other agents to make software, design parts and circuit boards, explore data, and create videos — all with domain tools, live viewers and sessions that persist across every machine you own. It includes a desktop app and an optional Harness device for following your agent, answering questions and speaking new tasks from your desk. The app, firmware, schematics, PCB layouts and enclosure CAD files are all open source.

Pros: what OpenHarness does well
- Combines software and open-hardware into one agent-building platform
- Supports Claude Code, Codex and other coding agents in domain-specific harnesses
- Sessions persist across machines you own
- Firmware, schematics, PCB layouts and enclosure CAD are all open source
Cons: where it falls short
- Advanced setup; hardware angle needs compatible gear
- Still early and ambitious in scope
- Best suited for builders comfortable with agents and maker tools
Who OpenHarness is for
Developers, makers and teams who want coding agents to do real work across software, hardware, design and media in persistent, self-owned environments.
Who can skip it
Users looking for a simple plug-and-play chat assistant or pure SaaS tool without any setup.
