About Hiver

Fast, replayable sandboxes for every browser, file, network, and tool action. Give agents a real working environment with governed files, policy-gated actions, and full replay across every run. Give agents access to files from a variety of file systems with precise ACLs: read-only, write-only, scoped by user, team, org, or workflow. Gate network access, protect credentials, and enforce policy around every file, API, tool, and action an agent uses. Replay every browser action, file change, network request, tool call, and approval across the full agent run.
