Cognition launches Devin Apps: describe a tool in chat and Devin builds and hosts it
Cognition launched Devin Apps on November 13: describe an internal tool in chat and Devin builds and hosts it as a live, private web app on its own cloud computer, at a stable URL gated by Devin login. It is built for internal tools and dashboards, not high-traffic production — and no pricing has been disclosed.

The News
Cognition launched Devin Apps on November 13, turning its coding agent Devin into a builder and host of small web apps. The idea is simple: a user describes an internal tool in chat, and Devin builds it and hosts it as a live, private web app on Devin's own cloud computer.
The apps live at a stable URL, but that URL only works when you are logged in to Devin — the app is never public. That design choice defines what Devin Apps is for: internal tools, dashboards and preview environments, the small apps a team builds for itself, rather than high-traffic production sites where thousands of strangers arrive at once.
Under the hood, the apps run on memory snapshots — saved states of the app that Devin can wake up on demand — and hibernate when idle. Billing follows awake time: you pay for the time the app is actually running, not for the time it sits unused. No pricing has been disclosed.
The launch was announced by Cognition on November 13 and covered by two independent writeups, all consistent on the date, the features and the private-only scope. Devin is one of the best-known AI coding agents — software that writes software — and Devin Apps extends it from writing code to running the finished product.
Cognition itself is private, so there is no stock to buy. The tickers on this story are read-throughs: Microsoft, whose GitHub Copilot is the leading coding assistant, and Alphabet, whose Google Antigravity is its rival agent product. Microsoft closed Friday at $523.88, up 0.17%; Alphabet closed at $295.77, down 0.98%.
Describe a tool in chat and Devin builds it, hosts it and keeps it private — the coding agent just became the IT department.
Why It Matters
Devin Apps matters because it closes the loop. Until now, a coding agent wrote code and handed it back to you — and you still had to find somewhere to run it. By hosting the app itself, Devin removes the deployment step entirely: describe the tool, get a live URL, share it with your team. For the internal tools that every company needs but nobody wants to maintain, that is a real saving.
The private-by-default design is the clever part. Internal tools hold company data, so making them public by accident is a genuine risk. Gating every app behind Devin login removes that risk by construction, and hibernation billing — pay only for awake time — matches how internal tools are actually used: in bursts, then ignored for days.
The competitive picture is nuanced. Microsoft's GitHub Copilot and Google's Antigravity are the incumbents in coding agents, and both are backed by companies with enormous distribution. Devin is a small private challenger. But Devin Apps is a differentiated move: neither rival hosts private internal apps as a product, and if teams start living inside Devin for their tools, switching costs grow.
The limits are honest ones. No pricing, a gradual rollout and an explicit warning that this is not for high-traffic production mean the product is a convenience today, not a platform yet. The test will be whether teams build real tools on it — and whether Cognition charges for them in a way that scales.
Analyst's Take
Our call is Bullish. Devin Apps is a small launch with a big idea inside it: the coding agent stops being a tool you ask for code and becomes the place where the finished app lives. Private-by-default hosting, hibernation billing and a stable URL solve the exact frictions that stop teams building internal tools — and internal tools are a huge, underserved market.
The read-through for Microsoft and Alphabet is neutral. GitHub Copilot and Google Antigravity both compete in coding agents, so a more capable Devin is competitive pressure — but Devin Apps targets internal tools, not the production apps where Copilot and Antigravity make their money, and Cognition is a small private company against two giants. That is why both are tagged mixed here: relevant context, not a direct hit.
The honest caveats are the missing pieces. No pricing has been disclosed, the rollout is gradual, and the product is explicitly not for high-traffic production — the use case that would make it a platform rather than a convenience. A coding agent that hosts apps is a genuinely useful step, but its commercial weight is unproven until pricing and adoption numbers appear.

FAQ
What is Devin Apps?
Devin Apps is a new feature from Cognition, the company behind Devin, an AI coding agent. You describe an internal tool in chat — a dashboard, a tracker, a preview environment — and Devin builds it and hosts it as a live web app on Devin's own cloud computer.
Is the app public?
No. The app lives at a stable URL that only works when you are logged in to Devin. It is never public, which is the point: these are internal tools for a team, not websites for the world.
How does billing work?
Apps run on memory snapshots, hibernate when idle, and bill on awake time — you pay for the time the app is actually running, not for the time it sits unused. No pricing has been disclosed, and the feature is rolling out gradually to activated accounts.
What is it good for?
Internal tools, dashboards and preview environments — the small apps teams build for themselves. It is not designed for high-traffic production use, where thousands of strangers hit the app at once.
Who is Cognition?
Cognition is the private company behind Devin, one of the best-known AI coding agents. It is not listed on a stock market, so the tickers on this story are read-throughs: Microsoft, whose GitHub Copilot competes in coding agents, and Alphabet, whose Google Antigravity is its rival product.
Why Microsoft and Alphabet?
Because coding agents are a competitive market. Microsoft owns GitHub Copilot and Alphabet builds Google Antigravity, so a new Devin capability is relevant to both — but as context, not as direct news about either company. Microsoft closed Friday at $523.88, up 0.17%; Alphabet closed at $295.77, down 0.98%.
