Autonomous AI software engineer for your issue tracker
Engineering teams who want to close tickets autonomously by assigning them to an AI agent

Good Fit If You're...
Engineering team that wants to close tickets without context-switching
Assign a GitHub issue or Jira ticket to Cosine, continue other work, and review the resulting PR. It plans the implementation, codes it, runs tests, and opens the PR — fully async.
Startup that wants Devin-level automation at a lower price
At $20/mo for Hobby (20 tasks), Cosine offers autonomous ticket resolution at a fraction of Devin's Teams plan. For startups with well-defined tickets, the ROI is immediate.
Automating repetitive bug fixes and maintenance work
Test failures, dependency upgrades, linting issues — well-scoped, recurring tasks that slow engineering teams. Assign them to Cosine and let engineers focus on architecture and product.
Validating autonomous agents before a larger commitment
The free tier of 80 tasks lets you run a real evaluation of autonomous coding — assign actual tickets from your backlog and judge the output before paying.

Strengths & Limitations
Strengths
- +Integrates directly with GitHub, Jira, and Linear — picks up and resolves tickets autonomously
- +72% on SWE-Lancer benchmark — strong real-world coding performance vs. Devin and Codex
- +Generous free tier — 80 tasks with no credit card required
- +Trains on data modeling how engineers reason — not just code completion patterns
Limitations
- -Async-only — no real-time IDE copilot mode
- -Newer and less proven in large enterprise codebases than Devin
- -Credit limits on Hobby tier can constrain teams with high ticket volume
- -No standalone IDE — requires existing GitHub/Jira/Linear workflow
