How to choose
Prioritize RepoIndex for pure analysis of large repos and free-claude-code or Abralo for generation workflows. Watch daily limits on freemium options like NexusAI before they force upgrades. Avoid agents whose jobs only mention monitoring or unrelated automation even if listed as free. Test open-source ones first for local control and no usage caps.
