Before you commit
Verify each agent's licensing to confirm full free usage without hidden commercial restrictions. Check self-hosting requirements like local compute needs or dependencies before deployment. Review community activity via upvotes to gauge ongoing support and updates. Test for integration limits with your existing tools or data sources. Confirm no unexpected paid tiers if your usage scales beyond personal projects.
