Arga turns natural language into reliable, production-grade tests. Describe what to test in plain English. Arga compiles it into a deterministic workflow, runs it in a fresh sandbox with API twins (Stripe, Slack, etc.), and auto-heals when things break. Under the hood, Arga is built on three primitives:
  • Semantic abstraction. Tests target elements by intent and meaning, not CSS selectors or XPaths. UI changes don’t break tests unless behavior actually changes.
  • Deterministic sandboxes. Each run starts from a fresh, identical state with API twins standing in for real services. Same input, same output, every time.
  • Auto-heal. When something fails, Arga reads from the browser, gathers context, and continues instead of just failing.
Connect Arga to the tools you already ship with, like Jira, Linear, GitHub, Sentry, and PostHog, so it knows what to test and why it matters. The same sandbox that validates code also validates AI agents. Drop an agent into a sandbox with twins to observe, red-team, or stress-test its behaviour without real-world side effects.

Quickstart

Start testing in under a minute.

How it works

Semantic abstraction, deterministic sandboxes, and auto-heal end to end.

Digital twins

Stateful replicas of external services that reset between runs.

Integrations

Context sources agents read from to decide what to test on each change.

​
What you can build on Arga
