Factory

Factory positions itself as an agent-native platform where "Droids" handle entire feature lifecycles, not just code generation. The pitch is compelling: you write a spec in Linear or Slack, a Droid picks it up, writes code in your IDE, opens a PR, and iterates on feedback. In practice, it's closer to a very opinionated CI/CD pipeline with LLM glue than a true autonomous agent. I tested Factory on a mid-sized TypeScript service. The Slack integration is genuinely useful: you can assign a Droid to a Linear ticket, and it'll draft an implementation plan before touching code. That planning step matters. Too many coding agents jump straight to code and produce plausible-looking garbage. Factory's Droids at least show their reasoning, which makes it easier to course-correct early. Where it shines: incident response. Factory's CLI can ingest logs, trace through your codebase, and propose fixes with surprising accuracy. I used it during a production outage involving a misconfigured Redis cache. The Droid identified the issue in under two minutes and generated a hotfix PR. That's faster than I could have managed alone, even knowing the codebase. Failure modes are predictable. Droids struggle with ambiguous specs. If your Linear ticket says "improve performance," expect a lot of back-and-forth or a generic solution. They also can't navigate complex legacy codebases well. Factory works best on greenfield projects or well-structured monorepos. The VSCode extension occasionally conflicts with other AI tools, particularly Cursor or GitHub Copilot, which is frustrating if you're already invested in those ecosystems. Compared to Devin or Sweep, Factory is less autonomous but more integrated. Devin gives you a sandboxed agent that works independently; Factory embeds into your existing workflow. That's a trade-off. You get less magic, but also fewer surprises. The enterprise pricing model is opaque, which is annoying. No public tiers, no self-serve trial. You have to talk to sales, which suggests this is aimed at teams with budget, not solo developers. The spec-writing feature is underrated. Factory can turn a vague Slack thread into a structured Linear ticket with acceptance criteria. It's not perfect, but it's faster than doing it manually, and it forces clarity before code gets written.
