About Sanbox

Sanbox is a self-improving computer in the cloud. It remembers context, turns experience into reusable skills, and keeps its tools, files, and workflows. Every task builds on the last. A built-in harness that uses tools, builds skills, and improves its workflows over time. The Computer remembers context, past work, and learned skills so tasks can continue over time, not restart from scratch. Give agents a browser to research, navigate websites, fill forms, and complete tasks in the browser.

About Stele

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions. Only one of these agents knows this was tried last spring and rolled back. KNOW-142 : a captcha on checkout shipped last spring and was reverted after two weeks. The bot traffic is real, though it spikes on release days and is quiet the rest of the time. A gate armed only during a release window would avoid repeating that.
