Upstash, the Silicon Valley company built by Turkish founders, has announced the next link in its agent infrastructure: [Upstash Box Browser](https://upstash.com/docs/box/overall/quickstart?ref=globalfeed.ai), a cloud browser built for AI agents. Agents can now take screenshots and videos of any page, run visual tests against a page or a dev server, and attach the evidence they produce directly to pull requests.

Two features stand out. First, the live-view URL: every run gets a link where you can watch, in real time, what the agent is doing in the browser; a welcome transparency move against the black-box-agent era. Second, full Chrome DevTools access for agents: console, network requests, debugging; everything a human developer sees, the agent now has. Control comes via the web console or a TypeScript SDK: a few lines create a box (Box.create), wire in a harness like Claude Code, and you can issue instructions at the level of "change the button color to blue, open a PR, include a verification screenshot".

Underneath sits Upstash Box, a secure, isolated cloud computer for agents: filesystem, shell, git and a runtime come ready; the box sleeps when idle and wakes in milliseconds, and its durable block storage sets it apart from classic throwaway sandboxes. The browser layer is free to try.

The bigger picture: agents learned to write code, and now they are learning to SEE what they wrote. A sandbox with a browser is on track to become standard equipment for agents that attach a screenshot answer to "did it work?" straight onto the PR; Upstash enters that race with a Turkish signature and infrastructure that wakes in a blink.
