Introducing Devin Apps

Devin added Apps, a way to turn something you describe into a private web app your team opens from a link. The apps are hosted on Devin's cloud computer, so they can reach your existing MCPs, integrations, and codebase. You can build with your own internal stack and components or start from a built-in template, such as a metrics dashboard, project status page, or review queue.

To make one, open Apps in the sidebar, describe what it should do, and click Build with Devin. Devin starts a session, asks any questions in its first message, then builds the app and puts it online. It shows up on the Apps page right away with its URL and a Building status until the first version is live. You can also ask for an app from any session, or have Devin publish a browser preview it already showed you.

Each app has a stable URL, and everyone who opens it has to sign in to Devin. Apps are never public. Share lets you limit access to people you add, your organization, or your whole enterprise. To change an app, click Edit in session and tell Devin what to update. Each change is a new version listed under Deployments, the URL stays the same, and if a new version fails to start, the previous one keeps serving. An automation can also refresh an app on a schedule or redeploy it when a branch changes.

Apps run on a single machine that sleeps when nobody is using it and wakes when someone opens the app, so the first load after a sleep can take a few seconds. Billing is based on how long the machine is awake. Any stack that serves HTTP on a port works, and an app can use SQLite or Postgres on the same machine or call the Devin API. Devin says it fits internal tools and dashboards, not high-traffic production services.
