Cosine vs Devin
Cosine and Devin are the two most capable commercial async coding agents, and they both start at the same price. The differences are in focus and transparency. Cosine is tightly integrated with issue trackers — GitHub Issues, Jira, and Linear — and publishes strong benchmark numbers (72% on SWE-Lancer). Devin has a broader 'AI software engineer' ambition, comes with Windsurf IDE access, and has more brand recognition, but is less transparent about success rates on real-world tasks. For teams that want to automate their existing ticket workflow, Cosine is the sharper tool. For teams that want a more general-purpose autonomous engineer, Devin has more surface area.
Cosine
Choose if: You want to automate ticket resolution directly from GitHub Issues, Jira, or Linear, with strong published benchmark performance and a generous no-credit-card free trial.
Autonomous AI software engineer for your issue tracker
Devin
Choose if: You want a broader autonomous AI software engineer that can handle diverse engineering tasks, comes with Windsurf IDE access, and is from the more established brand in this space.

Cosine: 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
Devin: Strengths & Limitations
Strengths
- +Fully autonomous — can plan, code, debug, and deploy independently
- +Handles complex multi-step engineering tasks
- +Can learn codebases and work with existing repos
- +Includes Windsurf IDE access (Cognition acquired Codeium)
Limitations
- -Can go off track on ambiguous tasks without clear specs
- -Slower than manual coding for simple tasks
- -Opaque process — harder to guide mid-task than copilot-style tools
- -Teams plan at $80/mo adds up for larger organizations
Which One Should You Pick?
Cosine is best for: Engineering teams who want to close tickets autonomously by assigning them to an AI agent.
Devin is best for: Engineering teams that want to delegate entire tasks to an AI agent.
