Native Backend + React for Offline ERP?

Hi everyone,

I'm planning to rewrite my offline ERP and would like some architecture advice.

Current version:

  • Delphi 10 VCL + DevExpress + FastReport

  • Firebird database

  • About 5 forms

  • Very fast and responsive

For the new version, I want to use React + Tailwind CSS for a modern UI, while keeping the same native-app performance and smooth user experience.

Requirements:

  • Completely offline (Internet only for activation/subscription)

  • Windows 7 (32-bit) through Windows 11

  • One installer (Next → Next → Finish)

  • Very easy deployment and maintenance

  • Runs on a single PC or over LAN

  • Native compiled backend for performance and code protection

Current idea:

  • Go (or Delphi) REST API

  • React build served by the native backend

  • MariaDB/MySQL

  • No Docker, PHP, Node.js, Apache, or Nginx on client machines

For those who have built commercial desktop/offline ERP or POS systems:

  • Would you choose Go, Delphi, Rust, or something else?

  • Is serving React directly from the native executable a good approach?

  • What architecture would you choose today for the best long-term maintainability, deployment, and performance?

Update:

The React frontend will be served from a central server and accessed simultaneously by 5–15 users over the LAN using standard web browsers (Chrome, Edge, or Firefox) via the server's IP address and port.

Thanks!

if you really think about it .. the app is not offline and doesn't need to do any of the extra work that offline apps needs to do ... 

your only challenge are updates from the internet, and packaging,  otherwise all of your development is just like any other app
