AI agent infrastructure
An agent that can click, run code, or pay needs a box to do it in. This hub is sandboxes, headless browsers, frameworks, and traces. E2B and similar give you a VM. Browser tools give you a real page. LangGraph and friends orchestrate steps. If you only need chat completions, you want Models, not this list.

Sandbox vs local agent?
Use a sandbox when untrusted model output might run commands. Local is fine for your own repo on your own machine (Claude Code, Cursor).
Do I need observability?
Yes as soon as more than one person depends on the agent. Traces beat screenshots of a demo that worked once.
Framework or just scripts?
Scripts until the graph branches. Then LangGraph or the vendor's own agent SDK. Do not start with a platform because a thread said so.
