Stateful API sandboxes for AI agent testing with REST and MCP endpoints that reset to a declared baseline.
Archal provisions stateful sandboxes containing simulations of third-party APIs (including GitHub, Linear, Slack, ClickUp, Stripe, and others) so AI agents, CI pipelines, and integration tests can run without touching production systems, creating test accounts, or hitting rate limits. Each sandbox environment persists changes across tool calls and resets to a known starting state on demand, with full visibility into requests, responses, mutations, and timing. Supported services include REST and MCP endpoints. New accounts receive $20 in free usage with no credit card required. Archal is a product of Archal.
