Use case overview

A reviewer had Devin set up a project, write code, install dependencies, test endpoints and add error handling in about 4 minutes on a simple task.

Reported experience

  1. What they did

    On day one of a week-long review, the reviewer gave Devin a plain-English prompt for a Node.js Express API with GET, POST and DELETE user endpoints and in-memory storage. Devin ran in its own sandbox with a browser, terminal and editor. It set up the project, wrote the code, installed dependencies, tested the endpoints with curl and added basic error handling.

  2. How it went

    It finished in about 4 minutes, against the reviewer's estimate of 5 minutes by hand. The reviewer says Devin's advantage is small on tasks this simple, and that it was slower than doing the work yourself on other tasks.

  3. Worth knowing

    Devin was priced at $500/month on the Teams plan, which the reviewer found hard to justify for solo work, and its output still needs review.

Example prompts

Try with Devin
Set up a new project called [name] in [language/framework] with an endpoint that [does X], installing the needed dependencies. Write the code, test the endpoint with sample requests, and add error handling for [invalid input or missing data]. Finish by showing me how to run it and the test results.
