Factory

AI software engineering agents (Droids) for enterprise development.

Factory relies on Fireworks AI for reliable inference and day-zero access to newly released open models for its coding agents. Because its Droids run inside customer environments with tight data controls, it deploys LangSmith self-hosted for observability, exporting traces to CloudWatch and using the Feedback API to close the loop from a Droid's comment back to the prompt behind it.
