Archal — Stateful simulated environments

Stateful simulated environments

Spin up environments for GitHub, Slack, Stripe, Linear, Supabase, Datadog, HubSpot, Jira and more that persist mutations during a run and reset to a declared baseline on demand.

REST and MCP interfaces

Call environments through familiar REST paths and payloads or through MCP tools, so existing agent code and tool definitions work with minimal changes.

One key, many sandboxes

A single API key creates and manages every sandbox and environment, with shared gateway routing while each environment keeps its own endpoint and readiness state.

Multi-environment sandboxes

Combine every environment a workflow needs into one sandbox, giving each its own readiness state and endpoint so end-to-end agent flows can be tested together.

Strengths & Pros

+Eliminates test-account headaches such as rate limits, shared state, and flaky third-party dependencies.
+Familiar REST and MCP surfaces mean existing agent code often works with little or no change.
+Second-level billing with free credits and no card required keeps experimentation cheap.
