Arsyn is not released yet. There is no build you can download today, and no date I am willing to promise. What is on this page instead is an honest account of what is built, what is half-built, and what is still just an intention.
Planned platforms
x64
x64 · AppImage
Apple Silicon
None of these are downloadable yet. macOS is not being worked on until the engine is stable on the other two.
No screenshots yet — so here are the facts
The homepage describes what Arsyn is meant to become. This is what the current build does. Where the two disagree, this list is the one that is true.
Import STL assemblies, build a kinematic chain with local reference frames, navigate the scene.
Draw wires between component pins in the 3D scene, with a symbol library behind it.
Lexer, parser, resolver and type checker are implemented. Vendor backends are not finished.
Zone/token simulation runs, but it does not write back to PLC variables. There is no hardware-in-the-loop today.
Not built. Wiring is manual only.
Not built. You cannot currently hand a client a TIA project produced by Arsyn.
Not built. The Ollama integration is a plan, not a feature.
Not built. Logical wiring only — no physical routing, no cable lengths in the BOM.

Still to build
Arsyn is early. Here is what remains to be built, with no dates attached — I won't promise one until it exists.
Automatic logical wiring generation from component typing, on top of the existing manual wiring tools.
Local code-gen and documentation assistant using deepseek-coder / llama3.1 — zero cloud calls.
Round-trip with TIA Portal, Codesys and major robot controllers (RAPID, KRL).
Physical cable routing on top of the logical wiring graph, with BOM-aware cable lengths.
Zone/token simulation writing back to live PLC variables for true hardware-in-the-loop testing.
Native Apple Silicon build, once the core engine stabilizes on Windows/Linux.
Development history
License & openness
Arsyn is free to use, including commercially. It is not open source: the application core is closed. The extension surface — module SDK, .arsyn file format and the Ars language — is what gets published, so you can build on Arsyn and read your own data without depending on us.
Read the licenseArsyn is free of charge, not open source. The core is closed. These are the parts intended for publication, so your projects and your modules do not depend on me staying in business.
The API modules register against, the module loader contract, and working example modules.
Full specification of the project file, so your data is readable without Arsyn installed.
The automation language, its grammar, and the compiler that lowers it to vendor backends.
The 3D engine, CAD, wiring and simulation code stay closed. Free to use, not published.
None of the above is published yet, so there is no repository to link to. When there is, the links will appear here and on the license page. Until then, treat the openness plan as an intention rather than a feature.
