The eval platform for autonomous software
Archal lets you test agents and code that touch third-party APIs without hitting the real services. We build working clones of popular SaaS platforms that hold state across requests and behave like the originals, so you catch bugs before your agent does something irreversible in production.
Archal is an eval platform that runs realistic scenarios against clones of real services to test autonomous software. It captures complete traces, supports replay and debugging, and integrates with CI to fail builds when behavior regresses.
Archal provisions stateful clones of real services (e.g., GitHub, Slack, Stripe, etc.) for each scenario. A scenario describes starting state, a task, and a success criterion. The platform executes the scenario against the clone, records every tool call, API request/response, and state change, and allows replay and diffing to diagnose regressions. These traces can be wired into existing CI so that failing behavior breaks the build on push. Clones persist state between runs and reset between scenarios, ensuring a known baseline for each test.
Who itβs for: Teams developing autonomous software that interacts with external services and requires end-to-end evaluation, trace capture, and CI integration.
