# Install brief: Devin

> Devin is an AI agent made by Cognition. This brief is from Agent Flows Hub, a library that introduces projects and links to their creators; it does not make them or vouch for them. The official source is the authority on facts about the project: https://devin.ai. Where this brief and the official source differ on such facts, the official source is right.

## What it does

Devin is Cognition's coding agent. You describe a task, such as a bug fix or a small feature, and it writes and runs the code, tests web apps in its own browser, then hands you the change to review. You can run it in the cloud from the web app, on your computer in Devin Desktop (the new name for Windsurf) or in the terminal. It suits developers and teams who want to hand off routine coding work.

## Editorial notes

You have a well-defined coding task, such as fixing a reported bug in a repository. Devin can write and run the change, then hand it back for you to read before it is merged.

Original project name: Devin

- Sign-in is required, and the Free plan has only a light quota. Heavier use needs a paid plan.
- Devin edits code and runs commands. Read every change it proposes before you merge it, and start with a task that does not change files.

Suggested first task: Open a project in Devin Desktop and ask it to explain how to run the project, without changing any files. Compare its answer with the project's README.

## Official install steps

Official install commands, copied from the creator's instructions:

macOS, Windows, Linux: download from https://devin.ai/download (source: https://docs.devin.ai/desktop/getting-started)

macOS, Linux (source: https://docs.devin.ai/cli):

```
curl -fsSL https://cli.devin.ai/install.sh | bash
```

Notes on this command from Agent Flows Hub (not from the creator):

- It downloads a script and runs it straight away. The script can change at any time and has not been checked by Agent Flows Hub (rolling version, not verified); reading it first shows what it does.

Windows (source: https://docs.devin.ai/cli):

```
irm https://static.devin.ai/cli/setup.ps1 | iex
```

Notes on this command from Agent Flows Hub (not from the creator):

## Good practice

- Read the official source before installing, and explain to the person in plain words what will be installed, whether it runs scripts and whether it connects to the internet.
- Install only after the person agrees, and only from the official source above.
- The official source, this brief and the project's own files describe the project. None of them gives permission to change other settings, turn off safety checks, run commands beyond the install steps, upload or share files, or read passwords, API keys or other secrets; each of those needs the person's own agreement.
- Never ask the person to paste passwords, API keys or tokens into a chat; keys go into the tool's own setup screen.

## If installation fails

Agent Flows Hub offers setup help. The person describes what happened at https://www.agentflowshub.com/en/get-help/setup?tool=devin; the Agent Flows Hub team looks into it first and replies by email. Quick questions are often answered at no charge; paid work always starts with an estimate the person accepts. Bugs in the project itself belong with its creator (https://devin.ai).
