Vibe Coding with Devin
The fully autonomous AI software engineer — assign a task, get a finished implementation.
What is Devin?
Devin by Cognition Labs is a fully autonomous AI software engineer. Unlike coding assistants that help you write code, Devin works independently — it reads documentation, plans implementations, writes code, debugs issues, and deploys applications. All on its own.
You interact with Devin through a Slack-like interface. Assign it a task — "build a rank tracker app" — and it spins up its own development environment, browses the web for docs, writes the code, tests it, and delivers a working result. You review and approve.
Builders use Devin for tasks they'd normally assign to a junior engineer. It handles the implementation while you focus on architecture, product decisions, and review.
Why Devin + YepAPI?
Fully autonomous
Devin plans, codes, tests, and deploys on its own. You review the result.
Browses docs
Devin reads YepAPI documentation itself — no need to paste llms.txt manually.
End-to-end delivery
From task assignment to working deployment. Devin handles the entire loop.
Devin takes autonomy to the extreme. Point it at YepAPI's docs and assign it a task: "Build a web scraping dashboard with export to CSV." Devin reads the API documentation, sets up the project, writes the integration code, builds the UI, tests everything, and delivers a working app. You just review.
This is the ultimate vibe coding workflow — you think about what to build, not how to build it. Devin handles the technical implementation while you focus on the product. It's like having a junior engineer who works 24/7 and never asks for clarification.

Frequently asked questions
Very. Devin sets up its own dev environment, browses the web, reads documentation, writes code, runs tests, and deploys. It can take a YepAPI integration task from zero to deployed app without any intermediate prompts from you.
Yes. Devin excels at tasks that would normally take a junior engineer a day or two. Multi-endpoint integrations, error handling, data transformation, UI building — it handles the full scope.
Codex works in a sandbox and delivers code/PRs. Devin goes further — it browses the web, reads external docs, sets up environments, and can deploy. Devin is more autonomous; Codex is more contained. Both work well with YepAPI.
