MAFIS is a fault injection observatory for lifelong multi-agent path finding. Inject faults. Measure degradation. Compare recovery.

What happens to a live fleet under sustained faults and cascading failures?
Every MAFIS run computes a fault-free baseline instantly, then runs the live simulation with faults active from tick one. The difference between the two runs is what you measure.
When an agent dies it becomes a permanent obstacle. Agents behind it replan, their new paths block others, and the ripple keeps spreading. MAFIS traces the chain and measures how deep and wide the damage goes.
MAFIS controls the variables that matter for fault resilience research. Configure a scenario, inject faults, and compare the results against a fault-free baseline, all in the browser.
Built on Bevy. Data-oriented and cache-friendly. Fault injection, heat propagation, and replanning compose as independent ECS systems.
Memory safety at compile time. No garbage collector. Handles 500 concurrent agents in a single browser tab.
Compiles to WebAssembly and runs in the browser. No server, no install. Open a URL, configure a scenario, run it.
Powered by Bevy, an open-source engine driven by its community of contributors.
MAFIS answers one question: how do multi-agent systems behave under faults? Everything else has a home.
