Simulated universes.
Real failures.
Multiverse generates universes, simulates users, injects failures, and verifies what actually happened—not what your agent claimed.
Request Early Access→what multiverse does
01
Generates universes
Personas × failure modes. Confused users, API timeouts, edge cases you didn't think of.
02
Simulates tools
Tool calls are intercepted and return realistic simulated data—including failures.
03
Verifies outcomes
success(universe) checks what actually happened, not what the agent claimed.
