Simantic timeline

Simantic offers virtual microcontrollers through a cloud API and a local simulator, alongside a GitHub bot that builds firmware and tests changes in simulation before posting a review. The founders presented the service on Hacker News on October 29, 2026.

The published CLI supports Apple Silicon macOS and x86-64 Linux, with Windows users directed to WSL2. Local execution still requires an account and an authentication check. The company says its hardware rigs compare simulated behavior with real silicon; its launch discussion says public silicon-validation benchmarks are still forthcoming.
