Are you looking for a simple and free tool for quickly creating professional Gantt charts? PlantUML can do it—but only if you remember all the necessary declarations and syntax, which is not always convenient. That's why I created the Gantt Chart Tool. You plan. The tool converts everything you need. No learning syntax, no delays — just a clean result.
Hey Product Hunt!
As a project manager, I have tried countless tools for planning and creating Gantt charts over the years. Some were powerful, some were pretty, others were complicated — but I never found anything that was fast, simple, and immediately usable so that I could quickly insert the output into an email, documentation, or presentation.
Then I discovered PlantUML.
The resulting charts? Incredibly clean, professional, and exportable to virtually anywhere.
The problem? You have to remember the syntax. And if you want to change or rearrange tasks, you have to rewrite everything manually.
I decided to create a tool where you just click on the tasks visually and PlantUML generates them for you. At first, it was a side tool for my own use... but the result was so good that it would be a shame to keep it to myself.
And so Gantt Chart Tool was born. (GanttTool.com)
Simple, fast, local, no registration required.
You plan → PlantUML is generated → your chart is ready to use.
I hope it serves you as well as it serves me.
I would love to hear your feedback, ideas, and maybe even ❤️.

Thank you all so much for the incredible support and for every upvote! This launch turned out to be a great success, and I’m truly grateful for it. I really hope the app will find its audience and become a helpful tool for many of you.
If you enjoy using it, I’d truly appreciate it if you recommended it to your friends or colleagues. Your support means a lot — thank you! Pavel
Congrats on the launch! Turning PlantUML Gantt charts into a visual click-and-generate workflow is such a smart way to remove the friction of remembering syntax.
Are you thinking about adding any kind of quick collaboration (like sharing a plan with a teammate) later on? Could be super handy.
Congrats on the launch! 🚀
Great launch! With a tool like GanttTool, when a team opens it for the first time, what’s the one belief you want them to walk away with in the first 10 seconds? Is it “I finally see how all my tasks link, and I’m in control” or “I can manage dependencies without drowning in spreadsheets”? Because for timeline tools, the moment users see clarity is often more important than the number of features.
