Drdroid vs Sherlocks Ai (2026)
Two AI SRE agents with real free tiers, which is rare in this lane, differing on openness against memory.
Doctor Droid is MIT licensed and free to self host, with an investigation knowledge graph, PlayBooks automation and an AlertOps Slack bot for triage and root cause. Sherlocks correlates observability signals for incident response and outage prevention with institutional memory that accumulates, free for thirty investigations a month then from 500 dollars, documenting 10 of 14 against 9. Own the code, or let the system learn your environment.
Choose Drdroid if
- MIT licensed and self hostable is a requirement rather than a preference.
- PlayBooks automation lets you encode what your team already knows how to do.
- You want no ceiling on investigation volume, which a free tier count imposes.
Choose Sherlocks Ai if
- Institutional memory is the value: the agent should know your systems better each month.
- Documented coverage is broader and outage prevention is in scope, not just response.
- Thirty free investigations a month is enough to prove it before you pay.
