{"id":99708,"title":"Arga Labs: Real-world sandboxes for multi-app agents and software","tagline":"Production-mirror sandboxes with digital twins of every SaaS integration","body":"**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.\n\nLaunch Video: \u003chttps://www.youtube.com/watch?v=OzEk5pYTvak\u003e\n\n**The problem: You’re a 1x tester**\n\n* You don’t have staging :(\n* You have staging, but it’s different from prod, and things still break after testing\n  * You mock integrations, which can be inaccurate\n  * You use real accounts to test integrations, but you hit rate limits, can’t clear states between tests, and can’t test at scale\n* 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\n* You have staging, but it’s difficult to merge concurrent changes without breaking something (for larger teams!)\n\n**Our Solution**\n\nWe 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.\n\nWe 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.\n\n![uploaded image](/media/?type=post\u0026id=99708\u0026key=user_uploads/3010892/cf335c26-a032-4a1d-bcc1-6c4863946abc)\n\nDemo of Github, Slack, Stripe twins on the Arga app: \u003chttps://www.youtube.com/watch?v=3ZPrIdGvPoo\u003e\n\nYou 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.\n\nValidation report:\n\n![uploaded image](/media/?type=post\u0026id=99708\u0026key=user_uploads/3010892/81258740-df00-46e1-9ba9-b2bbfd7a4572)\n\nClaude Code using arga CLI to read logs \u0026 test results:\n\n![uploaded image](/media/?type=post\u0026id=99708\u0026key=user_uploads/3202471/286496d9-28f2-4c01-a186-35235ed55189)\n\n**Our ask**\n\nTry us out!

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.\n\n![uploaded image](/media/?type=post\u0026id=99708\u0026key=user_uploads/3010892/3718524e-2a06-4aef-9bb2-0b6d9e18869e)\n\n","slug":"PwC-arga-labs-real-world-sandboxes-for-multi-app-agents-and-software","created_at":"2026-04-13T19:58:01.818Z","updated_at":"2026-05-25T02:41:03.508Z","total_vote_count":120,"url":"https://www.ycombinator.com/launches/PwC-arga-labs-real-world-sandboxes-for-multi-app-agents-and-software","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":31413,"name":"Arga Labs","slug":"arga-labs","url":"https://www.argalabs.com/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/6e3d9a7c1d8ec13bb1565520e7fc7a6ca3a8fa82.png","batch":"Spring 2026","industry":"B2B","tags":["Developer Tools","SaaS","Infrastructure"],"search_path":"https://bookface.ycombinator.com/company/31413"}}
