API sandboxes, built for AI agents

Your coding agent can start the sandbox & environments, connect to your API integrations, run tests, and inspect state changes. Sandboxes and environments are startable within seconds and take milliseconds to reset. Archal is a Y Combinator company (Summer 2026). YC-listed status: Active.
