Whenever we evaluate front-end frameworks, we score them based on more than just popularity.
Here's the checklist.
Open-source strengths
Huge communities
Flexible architecture
Large plugin ecosystem
Zero licensing fees
Faster experimentation
Commercial strengths
Enterprise UI components
Vendor support
Stable release cycles
Long-term maintenance
Better governance
Security-focused development
Questions I ask
How long will this application live?
How many developers will maintain it?
How much custom UI needs to be built?
Are compliance requirements important?
Do we need enterprise support?
If the project is a startup product, open-source usually wins.
If it's a large enterprise platform with complex dashboards, reporting, and long-term maintenance, integrated solutions like Ext JS become worth evaluating.
The framework itself matters less than how much engineering effort it saves over the lifetime of the project.
How does your team decide between open-source and commercial frameworks?
