Devin
The most powerful coding tool I've used. Investigates, plans, builds, pushes PRs, resolves merge conflicts — autonomously.
What I use it for
Pricing
Currently on free year via Lenny's Product Pass. Planning to keep after.
Where it shines
- Reads the entire project before touching anything. Investigation, then plan, then execution. The right order.
- Multi-agent sessions run in parallel — one thread investigating, another on requirements, a third implementing.
- Pushes PRs directly. Merge conflicts? It sees them in the repo and fixes them without asking.
- Large refactors, UI redesigns, bug hunts across multiple files. This is where Devin earns its keep.
Where it struggles
- Overkill for surgical edits. Claude Code and Codex are faster when you know exactly what to change.
- Can over-investigate simple tasks. Sometimes you just need a line changed, not a research project.
Notes
Got access through Lenny's Product Pass. Planning to keep permanently. Devin handles the complex multi-area work — Claude Code gets the targeted features, Codex fills gaps, but when something touches multiple areas of a codebase, Devin is the tool. It compounds. The more context it builds about your project, the better it gets.
How to try it
Connect a GitHub repo and give it a complex multi-file issue. The investigation phase alone will show you the difference.
