Where Devin Fits in Your Workflow
Optional reading: go deeper
Devin slots directly into the software development lifecycle your team already runs, taking on the heavy lifting at every stage instead of asking you to adopt a new process.
| Stage | What Devin does |
|---|---|
| Scoping & planning | Browse the auto-generated DeepWiki and ask questions about the codebase before work starts; generate implementation plans for tickets. |
| Development | Delegate a task and Devin writes the code on its own VM. |
| Code review | Devin Review acts as an independent second reviewer on every PR, whether a human or Devin authored it. |
| Testing | Devin runs your test suite, and where your org has computer use enabled, it can spin up the app and test it in a real browser. |
| Deployment | Devin works within your existing CI/CD: it pushes branches and PRs, and your pipelines and approvals stay exactly as they are. |
Is Devin here to replace me? No. Devin takes the work you have been putting off and frees your time for the work that matters: architecture, judgment, and what actually ships. It never merges to main without going through the same PR process as everyone else on your team, so the control points your team trusts stay intact.
The Plan-Act-Verify loop
Underneath every effective Devin workflow is the same three-beat process.
- Plan. Explore and scope before executing. Use Ask Devin to understand the code, then turn on Plan mode to scope the task. Devin analyzes the codebase, produces an implementation plan, and generates a context-rich prompt you can review before it writes a line of code. One common pattern is to explore locally, then execute in the cloud.
- Act. Hand off to an agent session. Devin works autonomously, editing, testing, and iterating on its own machine.
- Verify. Devin reviews its own PR diff, can test its changes end-to-end, and produces an annotated recording. Then you, the human engineer, do the final review.
The loop keeps you in control while Devin does the legwork: you decide what to build and whether to ship it, and Devin handles the steps in between.
