| Benchmarks | Not published | Not published |
| Best for | Delegated issue work, async PR generation, engineering throughput | Research, benchmarking, and academic SWE-bench experiments |
Devin is proprietary and best for delegated issue work, async pr generation, engineering throughput. Cognition's autonomous cloud agent. Assign issues or tasks; Devin works asynchronously — creating branches, writing code, running tests, and opening PRs. Self-serve plans use token quotas (March 2026); Enterprise uses ACUs.
SWE-agent is open source and best for research, benchmarking, and academic swe-bench experiments. Princeton NLP's research agent that helped pioneer the SWE-bench methodology. A benchmarking and research tool rather than a polished production agent.
Both tools are part of the 2026 AI coding agent landscape. The right choice depends on whether you need a cloud autonomous agent or a cloud autonomous agent, your budget, and which models you prefer. See the full list of coding agents on our coding agents page to compare more options.
