The short version
OpenClaw is one of the most popular open-source projects of the past year for good reason. It's an agent that actually does things, it runs on your own hardware, and you can shape it however you like. The trade-off is that you're also its operator and its security team.
Crevio is hosted, and it's built for one job, running an online business. The agent comes with a store, a checkout, a customer list, and an inbox to work in, plus managed integrations and approval steps for anything risky.
Which one should you pick?
If you enjoy running your own stack and want a personal agent across your chat apps, OpenClaw is a great project. If you want an agent that sells, follows up, and reports while you do something else, and you'd rather not maintain a server to get it, start with Crevio.
