Your app runs in the cloud, you open it in your browser, and your coding agent does the work. - [Host T3 Code in a Remote Sandbox](https://upstash.com/docs/box/guides/t3-code-setup.md): Run T3 Code in an Upstash Box and open it from any browser or phone. The box sleeps when you are away and wakes when you open the URL again. - [Run a Next.js App in a Cloud Sandbox with a Public URL](https://upstash.com/docs/box/guides/nextjs-setup.md): Scaffold a Next.js app inside an Upstash Box, run the dev server, and open it from any browser through a public URL, all with the Box SDK. - [Build an AI Code Review Agent for Pull Requests](https://upstash.com/docs/box/guides/code-review-agent.md): Build an AI code review agent with Upstash Box that clones a repo, inspects the pull request diff, and returns structured findings with severity and suggested fixes. - [Sandbox Backend for LangChain Deep Agents](https://upstash.com/docs/box/guides/langchain-deep-agents.md): Use langchain-upstash-box as a Deep Agents sandbox backend, so the agent's shell and file tools run in an isolated Upstash Box instead of on your machine. - [Playwright Web Scraping with a Cloud Browser](https://upstash.com/docs/box/guides/web-scraping-playwright.md): Scrape JavaScript-heavy sites with the managed headless Chromium in Upstash Box. Extract structured data through the SDK, then connect Playwright over CDP. - [Run a Browser Use Agent on a Daily Schedule](https://upstash.com/docs/box/guides/browser-use.md): Run a Browser Use agent inside Upstash Box and schedule it with cron. The example agent reads Hacker News every morning and saves a report to the box. - [Vercel AI SDK Code Interpreter and Shell Tools](https://upstash.com/docs/box/guides/ai-sdk-setup.md): Give Vercel AI SDK agents a cloud sandbox to run Python, JavaScript, and shell commands, manage files, and share app previews with Upstash Box. - [Run TanStack AI Coding Agents in a Cloud Sandbox](https://upstash.com/docs/box/guides/tanstack-setup.md): Run TanStack AI coding agents like Claude Code, Codex, and OpenCode inside Upstash Box with the native @tanstack/ai-sandbox-upstash-box provider. - [Vercel Eve Sandbox for Isolated Code Execution](https://upstash.com/docs/box/guides/eve-setup.md): Use @upstash/agentkit-eve to run Vercel Eve agent code in Upstash Box, with deny-all egress, setup baked into a snapshot, and one box per session. - [Run Pi Agent Tool Calls in a Remote Sandbox](https://upstash.com/docs/box/guides/pi-setup.md): Use the @upstash/box-pi extension to run every Pi tool call in an Upstash Box, while the agent and your model API keys stay on your machine. - [Self-Host an Always-On OpenClaw Agent in the Cloud](https://upstash.com/docs/box/guides/openclaw-setup.md): Install OpenClaw in a keep-alive Upstash Box over SSH, open its dashboard from your machine, and restart it automatically with an init script. - [Self-Host Hermes Agent in a Cloud Sandbox](https://upstash.com/docs/box/guides/hermes-setup.md): Install the Hermes agent by Nous Research in a keep-alive Upstash Box over SSH, and restart it automatically with an init script. - [Run Herdr Coding Agents in Isolated Cloud Sandboxes](https://upstash.com/docs/box/guides/herdr-setup.md): Use the Upstash Box plugin for Herdr to run coding agents from a Git worktree in their own box, then apply their changes locally as a reviewed patch. - [Self-Hosted Sandboxes for Claude Managed Agents](https://upstash.com/docs/box/guides/claude-managed-agents.md): Use Upstash Box as a self-hosted sandbox for Claude Managed Agents. Claude runs on Anthropic's side, and each session's bash commands and file edits run in its own box. - [Self-Hosted Sandboxes for the OpenAI Agents API](https://upstash.com/docs/box/guides/openai-agents-api.md): Use Upstash Box as a self-hosted sandbox for the OpenAI Agents API. The agent runs on OpenAI's side, and each session's commands run in its own box. - [In-App Coding Agent with CopilotKit](https://upstash.com/docs/box/guides/copilotkit.md): Add a CopilotKit chat to your Next.js app where each user talks to a coding agent running in their own Upstash Box, next to its shell and files.
