What are the best WYSIWYG editors for modern SaaS applications in 2026?

Hi everyone,

I’m currently working on a SaaS product and trying to choose a reliable WYSIWYG editor for handling rich text content.

My main requirements are:

  • Clean and modern UI

  • Easy integration with React or headless setup

  • Good performance (no lag with large content)

  • Customization options (toolbar, plugins, etc.)

I’ve looked into some popular options like TinyMCE and CKEditor, but I’m not fully satisfied with their flexibility and pricing for scaling projects.

I’m especially interested in:

  • Headless editors

  • Lightweight alternatives

  • Editors suitable for startups or growing SaaS platforms

Has anyone here tested modern editors recently?
Would love to hear your recommendations, pros/cons, or real-world experiences.

Thanks in advance! :raising_hands:
