The short version
Hermes Agent is a remarkable open-source project. It improves its own skills, remembers what you've worked on, and reaches you on more chat apps than almost anything else. The trade-off is that you're also its operator, choosing the models, hosting it, and keeping it secure.
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 approvals built around the actions that matter to a business.
Which one should you pick?
If you enjoy running your own stack and want a personal agent that's entirely yours, Hermes is a great choice. If you want an agent that sells, follows up, and reports while you do something else, start with Crevio.
