OpenClaw
Open-source agent by Open-source project. Free (plus AI model costs) as of November 2026.
Technical people who want a private, always-on agent in their own chat apps.
OpenClaw is the most powerful agent here for people willing to set it up: it lives in your chat apps, remembers everything locally, and acts on its own schedule. It's free, but you pay your AI provider. And you're giving an AI real access to your computer and accounts, so it needs care and some technical comfort.
