Arga Labs
Real-world sandboxes for testing and training AI agents
Arga Labs is a platform for deploying simulation environments that contain stateful twins of the APIs, CLIs, and MCP servers AI agents interact with. It addresses the need to test agent behavior in isolated sandboxes without deploying application code, letting users build, seed, and call service twins, then capture provider calls, responses, latency, side effects, and service-state changes for review.
Twin Runs spin up short-lived or permanent service twins across services such as Slack, GitHub, Google Calendar, Stripe, Salesforce, Jira, and others. Scenarios seed services with mock or production data using natural-language descriptions, while Test runs automate evaluations with defined judging criteria for commits or PRs. Agents connect by changing base URLs, and runs can be executed in staging, a preview server, or locally.
Arga Labs is aimed at engineering teams testing and training AI agents. Packaging includes a Free plan with limited pre-built twins and short run sessions, a Pro plan with long-running scenarios and test runner functionality, a Team edition scaled by usage and team size with onboarding and priority support, and an Enterprise edition offering custom twins, infrastructure, SSO, auditability, and dedicated support.
