VERDICT

Should I use PlantText?

Free & fast online PlantUML editor - planttext.com

Worth it. Buy if you're a developer or student who wants fast, text-based UML diagrams in a browser — the core is free and Pro is only $6/month. Skip it if you need drag-and-drop visual editing, formal vendor support, or a company with staying power.
