BUILD IT.
BREAK IT.
IMPROVE IT.
Put the open-source Myrmic runtime to the test. From September 9–28, build a real use case, break it to find its limits, or extend it.
The edge is not a small cloud.
Edge software has to deal with unreliable connectivity, constrained resources, and changing hardware — on top of state, messaging, and recovery. Strong tools exist for each piece, but teams still combine them differently for every system.
Myrmic brings these pieces into one application model. Write portable application logic in Rust and WebAssembly, while keeping hardware-specific capabilities native. The runtime handles state, messaging, and recovery for you.
The Build & Break Challenge is your chance to test it, explore its limits, and help shape what comes next.
HOW MYRMIC WORKS
- Write portable application logic in Rust and WebAssembly.
- Keep hardware-specific capabilities native.
- The runtime handles state, messaging, and recovery.
- One application model across distributed edge devices.
- Open-source, and testable today.

BEFORE EURORUST
Sharp edges included
Myrmic is a developer preview. We say so plainly:
- APIs may change and target coverage is incomplete.
- A hardware-bound Cell remains hardware-bound.
- Recovery of committed State does not make external physical effects exactly-once.
- Myrmic is not a PLC, hard-real-time controller, or functional-safety system.
Test Responsibly
Test only systems you own or are explicitly authorized to test.
Report potential security vulnerabilities privately, not on Discord or public GitHub Issues. Privately reported findings can still qualify for an award.
Security contact: security@myrmic.dev
Security policy: View our SECURITY.md
- Hardware is welcome, but not required.
- Small, reproducible findings are valuable, including things that don’t work.
