BU is a fully autonomous agent API that enables deployment of AI agents with comprehensive capabilities. The platform allows users to deploy agents that can work continuously with a single prompt, providing persistent operation without needing to restart.

BU gives agents access to a browser that works with any website, solves CAPTCHAs, and provides 195+ country proxies. Agents also get terminal access to run commands and execute scripts, along with a file system and persistent memory for reading, writing, and managing files across sessions. The platform includes integrations with Slack, Gmail, Linear, and 100+ other services.

BU features profiles with scoped authentication so agents start logged in, workspaces with persistent storage allowing agents to remember information across sessions, and keep-alive functionality to resume sessions without starting over. The platform provides live URLs to watch agents work in real-time, cost controls for setting per-session spending limits, and structured JSON schema output for deterministic results.

The platform enables complex workflows through a single API call, creating agents that work 24/7 and can report back to Slack. BU is designed to handle monitoring, testing, and web scraping tasks autonomously.

BU targets developers and organizations looking to automate web interactions and workflows using AI agents. The platform integrates with popular tools and services while providing comprehensive control over agent behavior and costs.
