Validation infrastructure for autonomous AI agents
Arga Labs builds real-world sandboxes, API twins, and validation infrastructure for AI agents, AI coding workflows, and production-shaped software testing — so your systems behave in the wild exactly as they do in the lab.
Access is whitelist-only while in private preview.

Three layers for shipping agents that survive reality
Most AI fails the moment it leaves the demo. Arga Labs reconstructs the conditions of production so you can validate behavior before your users do.
Real-world sandboxes
Spin up isolated, production-shaped environments in seconds. Filesystems, networks, services and state — a faithful copy of the messy real world your agents will actually face.
- Ephemeral & reproducible
- Snapshot + time-travel
- Zero side-effects
API twins
Deterministic, record-and-replay twins of the third-party APIs your agents depend on. Test against Stripe, Gmail, Slack and hundreds more without touching real accounts.
- 200+ pre-built twins
- Record from prod traffic
- Fault & latency injection
Validation infrastructure
A grading and evaluation layer that scores agent behavior against real outcomes. Catch regressions, hallucinated actions and unsafe steps before they ship.
- Trace-level assertions
- Regression gating in CI
- Continuous eval suites
// how it works
From production trace to passing test in minutes
Capture reality
Record real traffic, API responses and environment state from your production systems into reusable fixtures.
Spawn a twin
Instantly reconstruct a sandbox with API twins wired in. Deterministic, isolated, and identical for every run.
Run your agent
Point your agent, coding workflow or test suite at the sandbox. Inject faults, latency and edge cases on demand.
Validate & gate
Score behavior against real outcomes, assert at the trace level, and block regressions before they reach prod.
// use cases
Built for teams shipping software that acts on its own
Autonomous agents
Validate multi-step agents that browse, call tools and take real actions — without risking live systems.
AI coding workflows
Give coding agents a real environment to build, run and verify changes against, not a hallucinated stub.
Production-shaped testing
Replace brittle mocks with high-fidelity twins that behave like the real thing under load and failure.
Eval & CI gating
Run continuous evals on every commit and block regressions before they reach your customers.
