Real Protocols. Real Models. Real Testing.
OPEN DEVICE
LIBRARY
Get instant access to a growing library of ready-to-use device models inspired by real-world equipment and vendors. Extend it freely and keep your projects moving without waiting for hardware.
REAL PROTOCOL CONNECTIVITY
Connect simulated devices over real industrial protocols—so your apps, PLC logic, and dashboards behave like they would in production. Validate integrations end-to-end, not just unit tests.
LLM-First Model Generation
Turn a datasheet or device spec into a working SPX model fast—guided by the golden standard in spx-examples (GitHub) and agent specs. Generate consistent models that match your conventions from day one.
JSON/YAML
Device DSL
Models are defined in clean, human-readable JSON/YAML with strict patterns for consistency and scale. Easy to review, easy to version, easy to evolve with your team.
Scenarios & Fault Injection
Script real-world sequences and edge cases: timing quirks, faults, dropouts, and abnormal states. Reproduce bugs on demand and harden your system against the unexpected.
Observe, Debug, Automate
Watch live state, signals, and protocol traffic to understand behavior instantly. Run simulations in CI for repeatable validation—so every change proves itself automatically.
