A free model is included so you can install and see the harness work on everyday coding tasks within minutes. When you're ready for heavier work, bring your own keys and run Claude, GPT, Gemini, or any model you already pay for.

Help & resources

Will this slow my developers down?

The opposite. In practice, security runs at generation time, so code arrives clean on the first pass: fewer review loops, no scan-fix-regenerate cycle, no rework tickets.

What's the difference between a coding harness and a coding agent?

An agent writes code. A harness runs the agent inside a loop you define: policies applied before generation, verification after, and a sandbox around every action. Symbiotic Code is the harness; the models are whichever you pick.

Does it work on code my team writes by hand?

Yes. The IDE plugin, PR apps, and CI integration scan and fix any code in the repo, not just what the agent produced.

What happens to my CLAUDE.md, skills, and MCP servers?

They carry over as-is. Most developers are productive within a few minutes.
