Simantic

Simantic is a firmware simulation platform that runs real firmware on simulated hardware, from a single microcontroller up to connected devices. Engineers use it to run, inspect and test an embedded system without depending on physical boards for every check. The company is backed by Y Combinator. The product is aimed at embedded and firmware teams who want reproducible tests. Simantic states that its focus is on validating the simulator itself: it uses real silicon as the reference, publishes a validation standard, and aims to give clear evidence of what works and where the boundaries of the simulation lie. The site shows signal level detail such as reset recovery timing and I2C bus behavior as examples of what is modeled. Tooling includes a command line interface and MCP features for working with AI coding agents, a GitHub integration with continuous integration runtime, a web dashboard for firmware runtime analytics, and support for custom integration tests. There are two plans. The Community plan is for individuals getting started, is currently offered through a waitlist, and includes limited CLI and MCP access, five hours of monthly CI runtime, the dashboard and custom integration tests. The Enterprise plan is priced through the sales team and adds advanced CLI and MCP features, 50 hours of monthly CI runtime per seat, early access to pre production component models, private hosting, single sign on, a dedicated account manager, priority support and a custom service level agreement.
