OpenClaw is free, open source, self-hosted, and one of the most-starred projects on GitHub for good reason. It is genuinely private and genuinely yours. If those are your deciding factors, use it — we would rather you know that on this page than discover it after a migration. What follows is what tends to break when one assistant becomes several agents doing real work.
Two techniques showed up on GitHub, turned out to work, and are now plugins in our catalog: one shortens output without touching code or error text, the other makes the model reach for the smallest correct solution. On a self-hosted setup, adopting either means reading a stranger's repo, understanding it, and re-engineering your own prompts and pipeline. Here it is one click, sandboxed, and everyone's agents get better at once. In a field moving weekly, that difference compounds faster than any single feature.
Create an account, add your model key, and write your first agent's soul. The rest of the crew can arrive in one click.
