A virtual society of AI users
that behave like real people
Upload your prototype. Thousands of synthetic users explore it. You get instant insights before any humans ever see it.
Agent encountered 404 on /pricing
During the automated simulation run #442, Agent-128 attempted to navigate to the pricing page from the landing page but encountered a broken link.
We should check the routing configuration in routes.ts and ensure the page is deployed.
I've automatically created a regression test for this path. It will be included in the next simulation run.
Trusted by Innovators
A platform where developers upload prototypes and thousands of AI agents use them.
Crowdi agents aren't just scripts. They have personas, goals, memories, and behavioral probabilities.
They form emergent behaviors, stress-test your onboarding, and reveal retention loops before you launch.
Upload Prototype
Connect your staging environment or upload a build. Crowdi parses your UI automatically.
Agent Simulation
Thousands of AI agents with unique personas explore your app, behaving like real humans.

Crowdi CLI
Connect Crowdi to your CI/CD pipeline. Run simulations on every pull request and block builds if UX metrics drop.
Semantic Insight Search
Ask questions about your product's usage. 'Where do users get stuck?' 'Why is retention dropping?'
Live Pulse
Watch agents interact with your app in real-time. See their thoughts, actions, and frustrations as they happen.
Enterprise Security
SOC2 Type II certified. Your data is encrypted at rest and in transit. We never train on your proprietary code.
Branch Previews
Automatically deploy agents to every feature branch. Catch regressions before they merge to main.
Meet the Crowd
A diverse library of AI personas with unique goals, memories, and behavioral patterns.

Time Saved
Bugs Found
Sandboxed. Isolated. Secure.
We run simulations in strictly isolated environments. Agents cannot access production data or perform destructive operations.
Private Simulations
Your data never leaves our encrypted enclave.
Staging-Only Access
Agents operate on staging URLs, never production.
Strict Rate Limiting
Prevent accidental DDoS with intelligent throttling.
Our Vision
The future of product development isn't just faster coding. It's predictive testing with synthetic societies.
Imagine a world where you never launch a confusing feature again. Where you know exactly how a million users will react before you write a single line of production code. Crowdi is building the default testing layer for the AI age.
