tl;dr: become a 100x tester with Arga by giving your agents staging environments scoped to a change. We spin up twins of your integrations (Slack, Stripe, etc.) and dependencies (DB, Redis), and deploy only the services that were changed. Everything else is routed to prod.

The problem: You’re a 1x tester

• You don’t have staging :(
• You have staging, but it’s different from prod, and things still break after testing
  • You mock integrations, which can be inaccurate
  • You use real accounts to test integrations, but you hit rate limits, can’t clear states between tests, and can’t test at scale
• You have staging, but your agents can’t automatically test changes so you’re stuck at being a 1x tester despite being a 100x engineer
• You have staging, but it’s difficult to merge concurrent changes without breaking something (for larger teams!)

Our Solution

We spin up a temporary staging of your app every time you open a PR. Only the services you change are redeployed; all other services are routed to prod. Your dependencies are deployed as in-memory sidecars, so nothing corrupts prod data. For example, you can configure the tests to read from the prod database and perform all write commands to the sidecar; you can also configure everything to be routed to the sidecar.

We also spin up twins of services your app uses: Stripe, Slack, GSuite, Hubspot, and more, so you don’t hit the real API. This lets you test more thoroughly: you can catch weird edge cases, simulate failure modes, and run tests in parallel without worrying about rate limits. All twins are fully compatible with any SDK, expose the same API endpoints, and support webhook events. You can seed any twin in natural language, or select from our pre-set scenarios.

You or your agent can prompt Arga via web, API, CLI, or MCP to automatically generate tests for your PR, run them, and stream the results and logs back. This allows them to know what was tested, what broke, and which calls/functions caused the failure. They can use this information to go back and fix the code, so you’ll have a fully-tested and passing PR before you look at it.

The Team

Akira and Phillip met each other in first-year calculus at UBC. At the time, Akira was 14 and Phillip was studying neuroscience to pursue research in human biology. Within a year of pivoting to CS, Phillip built a dev tool at Amazon that saved 10 weeks / year of engineering hours as an intern. While interning at Stripe, Akira realized that a high-fidelity “staging” was the key to unlocking dev productivity and was surprised that most companies don’t have proper staging that actually mirrored prod. Now they’re solving that problem.
