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 ❤️. Pavel

@vlcek Yes! Manual rewriting PlantUML tasks is the worst. This solves a major friction point. Trying it now.

Pavel Vlcek

@masump Totally agree — rewriting tasks manually was my biggest pain point too. That’s exactly why I built this tool! Really glad it resonates with you. Let me know how it works for you once you try it

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! 🚀

Pavel Vlcek

@damir_maham Thanks a lot, Damir! For this project, I’m not planning to add collaboration — it’s really just a small side tool.
But I’m already working on a new project focused on efficient task management for freelancers and small teams, something like digital sticky notes in a Kanban flow. That one will be released under my official company and will have more room for features. 🙂

Damir Mahamedov

@vlcek Gotit, thanks for the clarification. Makes total sense for a focused side tool, keeping it simple is a real strength.

Digital sticky notes + Kanban flow for freelancers and small teams is such a great direction? 🧐 Interesting case

Wishing you success with both launches! 🚀

Viktor Shumylo

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.

Pavel Vlcek

@vik_sh Thanks a lot, Viktor! Really appreciate it. I truly hope the tool finds its audience and helps people work with Gantt charts more comfortably, just as intended.
