Cognition launches Devin Apps to host private internal web tools

Cognition introduced Devin Apps on 13 November 2026, one day after upgrading Devin Teams with SWE-2 sessions, enabling engineering teams to build, host and share private web applications directly from Devin’s cloud computer without configuring third-party hosting. From the Apps sidebar or any active session (including promoting an existing session browser preview), users describe a tool or pick a template for metrics dashboards, status pages or review queues, and Devin serves a production build at a stable preview.devinapps.com URL.

Devin-authenticated sharing, snapshot sleep billing and safe rollbacks

Every visitor must sign in to Devin, as Apps are never public; creators restrict access to named people, an organisation or a whole enterprise, and organisation admins can pin core Apps for everyone.

Because each App runs on Devin’s own VM with access to local SQLite or PostgreSQL databases, uploaded files, repository context, MCP servers and the Devin API, any framework serving HTTP on a port works. Teams ship changes via Edit in session or scheduled and branch-triggered automations while keeping the previous deployment online if an update fails to start, and memory snapshots put idle VMs to sleep so compute bills only while awake.

Technical details

URL pattern and visibility

Stable preview.devinapps.com subdomains; strictly private behind mandatory Devin sign-in

Runtime and data storage

Single-VM production HTTP build with on-machine SQLite, PostgreSQL, file uploads, MCPs and Devin API

Compute lifecycle and billing

Memory-snapshot hibernation when idle; wakes on visit in a few seconds and bills awake duration only

Update and rollback model

Edit in session, scheduled refreshes or branch deploys; prior version keeps serving if a build fails

Release details & context

Single-machine capacity boundaries and full-stack staging previews

Cognition’s product guide notes that each Devin App runs on a single machine rather than an auto-scaling cluster, making it suited to internal admin panels, approval queues, scheduled metrics boards and clickable full-stack staging copies (frontend, backend, database and background workers) rather than high-traffic public services.

Renaming an App never alters its assigned preview.devinapps.com hostname, and Devin verifies functionality against a development server in a browser preview before compiling and serving the production build.

Common questions

Can a Devin App be shared publicly on the open web without requiring viewers to log in?

No, Devin Apps are strictly private and require every visitor to sign in to Devin within the creator’s invited user, organisation or enterprise scope.

Does a Devin App consume compute credits continuously overnight when no teammates have it open?

No, memory snapshots hibernate the underlying machine while idle and wake it on the next visit, billing compute only for the time the machine stays awake.
