The license model, the freedom of creating what ever you want, the stability, AI integrations, Web-based and deployed, endles integration possibilities, and not to forget, the fantastic company behind it, Inductive Automation!

The licensing model is the single biggest thing. Unlimited tags, unlimited clients, unlimited connections for one price means I never had to design around a tag count or worry that adding a sensor would cost more. Coming from a student budget that mattered, but it also means the architecture decisions I made were driven by what the process needed rather than what the license allowed. Perspective being genuinely web-based is the other standout. No client installs, no per-seat licensing, and the same project renders on a laptop and a phone without me building it twice. The Modbus TCP driver being native meant I had an ESP32 talking to a real SCADA platform in an afternoon. Database integration is built into the platform rather than bolted on, so when I built an ISA-18.2 alarm journal on PostgreSQL, I could bind custom components directly to SQL queries and build exactly the analytics dashboard I wanted instead of accepting stock components. Inductive University deserves a mention too. Over 600 free videos with a real credential at the end is a genuinely serious training resource, and it's free to anyone with an account.

One of the most amazing things about Ignition is its design capability and how easy it is to learn. I really like how the built-in components are put together, and how easily those components can be modified with simple CSS classes. On top of that, Ignition is very intuitive, especially when it comes to making those “hard,” stubborn connections to devices, servers, and/or API endpoints. I also appreciate the ability to easily build your own Python/Jython functions and libraries. Overall, Ignition is the most capable, reliable, scalable, and intuitive SCADA platform I have come across.
