Sinatra vs Devin, OpenHands, and Factory

Sinatra is an autonomous coding agent you hand a GitHub or Linear issue like a teammate. Label the issue on GitHub or assign it in Linear, and it opens a branch, writes the code, runs your tests, and ships a reviewed PR. It's model-agnostic (bring your own key), passes your LLM cost through with no markup, and is a flat $20 per member. Here's how it compares.

1. Factory supports BYOK in their CLI only, not their web/mobile droids.
2. Sinatra passes LLM token costs through at provider rates with zero markup. Devin and Factory bundle LLM into seat or credit pricing; OpenHands also offers at-cost usage.
3. Every Sinatra tier publishes a price. Devin, OpenHands, and Factory all gate their enterprise tiers behind "contact sales".
4. Submit a review that requests changes and Sinatra reworks and pushes the follow-up commit autonomously, with no re-trigger or mention needed. OpenHands and Factory require an @openhands / @droid mention to act on PR feedback. Devin auto-responds to PR comments only while its session is unarchived.
5. Label a GitHub issue and Sinatra runs the whole loop on it. The label ships with the GitHub App install. OpenHands Cloud offers a comparable label/mention trigger. Factory requires installing their droid-action workflow and an API key per repo; Devin doesn't document a GitHub-issue trigger.
