Devin AI vs OpenDevin vs SWE-agent
Agents that take an issue and try to produce a working patch, rather than autocompleting while you type.
All 3 checked against the vendor's own pricing page · checked Sep 2026
These tools sit in different categories in our directory, which reflects where each is strongest rather than a filing error.
Which should you pick?
Devin is the commercial product with the most polish and the highest price. OpenDevin, now OpenHands, is the open reimplementation of that idea, and is where to go if you want to run this yourself or see how it works. SWE-agent came out of Princeton research and is the most honest about its own benchmark numbers, which makes it the best starting point for evaluating whether the category works for your codebase at all. Treat all three as assistants that open pull requests, not as replacements for the review that follows.
