Factory
Autonomous AI 'droids' that handle full software engineering tasks.
What it is
Factory ships specialized droids — Code Droid, Reliability Droid, Tutorial Droid — that own narrower slices of engineering work than Devin attempts. The bet is that focused agents beat generalists.
Notes from using it
Factory's specialization bet — multiple narrower agents (Code Droid, Reliability Droid, Tutorial Droid) instead of one generalist — has produced consistently good results on the focused tasks each droid is built for. The premise that focused agents beat generalists at task quality holds up in practice.
The Code Droid in particular handles well-scoped engineering tasks better than Devin on the same input in many head-to-heads operators have run. The Reliability Droid catches issues in flight that human reviewers miss. The total surface of what Factory does is narrower than Devin's autonomous-engineer pitch, but the depth on each slice is real.
The enterprise-only motion limits who can evaluate Factory. There's no self-serve pilot, no try-it-yourself path. For engineering teams running serious AI-driven development at scale, that's a fair friction; for everyone else, it locks Factory out of the comparison until the team is ready to engage on procurement terms.
Where it shines
- Specialization tends to beat generalist autonomy at task quality.
- Strong eval-driven culture inside the company.
Where it falls down
- Smaller surface than Devin or Cursor.
- Enterprise-only sales motion.

If you're trying to put AI behind any of these functions, Factory is worth a look:
- AI for Code Review — PR review, refactor suggestions, test generation, on-call triage.
