What is AgentEnv + REA?

How recorded browser sessions become replay environments — and what rea.run does (and does not) provide.

Short answer

• REA can record browser sessions / HAR against targets you are authorized to analyze.
• Scale AgentEnv turns those captures into RL-style environments and exposes replay as MCP tools.
• earakely-scale (Scale Labs) published 50+ such environments on Hugging Face.
• rea.run mirrors that catalog for community teaching: categories, notes, baselines, deep links — not the runtime.

Suggested path

1. Authorize the target (own / OSS / written permission / approved lab).
2. Capture the browser session with REA (HAR or capture-browser-scenario).
3. Replay as AgentEnv MCP tools on Scale AgentEnv / the HF space — not on rea.run.

Where to go next

Authorized use only

Capture and replay only against software you own, OSS under a compatible license, malware in an approved lab, or with written permission. See legal boundary.
