Before you commit
Verify the pricing text explicitly states lifetime or one-time with no hidden renewal clauses. Confirm whether the agent runs fully locally or requires any cloud dependency that could add future costs. Check platform limits such as device count, update access, or feature caps that may appear after purchase. Review self-host requirements and hardware needs before committing, especially for local-first tools.
