Program PLCs like modern software.
AI-native. Deterministic. Multi-target.
Finally bring modern engineering practices to industrial automation.
- 100% text-based
- Git
- CI/CD
- Unit tests
- Simulation without hardware
One codebase → multiple PLC platforms.
The best of software engineering, for industrial control systems.
Version control
Git native
Track every change. Branch, merge, rollback like real software.
CI/CD pipelines
Automated builds
Compile, test and deploy your control programs from any CI runner.
Unit & integration testing
Test before commissioning
Catch logic bugs at your desk. Validate end-to-end scenarios automatically.
Simulation without hardware
Logical time
Run your full PLC program on your laptop, faster than real time.
Modular, maintainable code
Strong typing & OOP
Generics, packages, type safety. Build reusable components that scale.
AI-assisted development
Copilot, GPT, Claude
Pure text code that AI agents can read, generate and refactor.
IF IT COMPILES, IT WORKS.
For automation engineers & developers.
Greenfield
Build new automation systems 10× faster
New plant, clean line. AI generates a complete Chronax program, tests it, and compiles to your target PLC in one command.
Brownfield · Retrofit
Migrate legacy PLC systems without rewriting
Import Siemens S7, Schneider Unity Pro & Control Expert. AI-powered modernization, automatic tests. Migrate a program from one platform to another in days, not months.
Maintenance
Take over existing systems in days, not months
Undocumented code, unclear logic. Chronax: AI refactoring, tests, simulation. Take back control of legacy systems fast.
Compile to any PLC platform.
Need another platform? New backends are added in weeks, not months.
Everything from the command line.
Think cargo for industrial automation — the tool that made Rust developers love their workflow.
The chronax CLI is the single entry point for your
entire workflow. Scaffold a project, create packages from templates, run unit tests
and black-box scenarios, simulate, debug, and compile to any target — all without
leaving your terminal.
- Scaffold projects, machines, packages, and test templates
- Test unit tests and black-box scenario tests
- Simulate & debug on your laptop, faster than real-time
- Compile to Siemens, Schneider, Beckhoff, Codesys, native — in one command
Developers write text. Engineers see diagrams.
Same source file. Zero information loss. Switch between text and graphical views instantly — Ladder, Grafcet (SFC), and Function Block Diagrams.
The first automation IDE that speaks both languages.
Two modes, one click apart. Software developers get a VS Code-like environment with terminal, Git integration and refactoring tools. Automation engineers get a project tree, function block library and visual editors — just like TIA Portal or Control Expert, but on a modern foundation.
From graphical lock-in
to modern engineering.
Without Chronax
- Proprietary graphical IDEs
- Binary formats unreadable by AI
- No Git, no CI/CD, no real testing
- Bugs discovered on-site (costly)
- Vendor lock-in
- Talent shortage
With Chronax
- Pure text code (VS Code, Git workflows)
- AI-native (generate, refactor, fix)
- Unit tests + simulation
- Deterministic compiler
- One codebase → multiple platforms
- Any developer can build automation
While software teams ship with Git and AI agents, automation engineers were stuck dragging blocks. Chronax breaks that lock-in: the compiler guarantees determinism and correctness — AI generates, Chronax ensures it runs.
Free compiler. Early access.
Chronax compiler-as-a-service rolls out progressively over the coming weeks, free for early adopters. Join the waitlist to get access on a first-come, first-served basis.
- Free during early access program
- Compile to Siemens, Schneider, native and more
