Smactu

A VS Code extension with modern development tools for Omron Sysmac projects.

In Development

The Problem

Sysmac Studio is stuck in the past. Binary project files you can't diff. No real version control. No AI assistance. Slow IDE that fights you at every turn.

Modern software teams use VS Code, Git, and AI tools every day. Why should automation engineers be locked out?

The Solution

Smactu is a VS Code extension that brings modern development workflows to Omron Sysmac projects. Write, test, and collaborate using the tools developers already know — while Sysmac Studio handles the build and download.

  • Git version control — Real diffs, branches, pull requests, and code review for PLC code
  • Bring your own AI — Use Copilot, Claude, or any VS Code AI extension with your PLC code
  • Simulation — Test your logic without PLC hardware. Develop anywhere.
  • VS Code ecosystem — Extensions, themes, keybindings, remote development — everything you're used to
  • Your projects, your Git — GitHub, GitLab, Bitbucket, or self-hosted. No vendor cloud required.

No Vendor Lock-in

Your projects are stored in Git-friendly formats. Your code lives in your repositories. You're not renting access to your own work.

  • Open formats — Plain text files that any tool can read
  • Any Git provider — Works with GitHub, GitLab, Bitbucket, Azure DevOps, or just plain Git
  • Fair pricing — Monthly, annual, or perpetual license options
  • Export everything — Your data is yours. Take it anywhere.
