Archal
What is Archal?
Archal is a testing platform that provides isolated, stateful sandboxes for APIs used by coding agents and integration workflows. It simulates services such as GitHub, Slack, Linear, Stripe, Datadog, Supabase, and others through REST and MCP interfaces. Developers can create a sandbox with a known starting state, run tasks, inspect requests and mutations, and reset environments for repeatable testing without production accounts, rate limits, or persistent test data.
How to use Archal?
Create an Archal account and connect the platform to your coding agent using the provided setup command. Choose one or more API environments, create a sandbox with a known baseline, and use the supplied REST or MCP endpoints to run integration tasks. Inspect requests, responses, mutations, timing, and usage, then reset the sandbox to its original state for another test.
