ReSim.ai Information

You're spending too much time maintaining test infrastructure instead of fixing what's actually wrong with your robot. SignalFlag is a test infrastructure platform for physical AI. Point your agent at our MCP and it builds your test and evaluation infrastructure on components already running in production, so what your agent builds is stable enough to keep and consistent with what every other team is building. Teams build their own test infrastructure for good reasons: ownership, speed, control. Then an agent writes a working harness in an afternoon and hands back four hundred lines of code that someone now maintains. The same thing happens on the perception team, the controls team, and the autonomy team, and now there are three versions of the same foundation and no way to compare results across them. With SignalFlag, field logs, hardware runs, log replay, and simulation run through one place, with results the whole organization can compare. However your team prefers to work, use the MCP, our CLI, our API, or the web app, it’s all the same world class platform underneath. Ready to get started? There’s no per-seat pricing, and a free tier is now available at SignalFlag.ai. SignalFlag was formerly ReSim.
