About gantts.app
gantts.app is a free, no-login Gantt chart maker that runs entirely in your web browser. Our goal is simple: let anyone plan a project on a beautiful timeline in seconds, without an account, a download, or a paywall.
Why we built it
Most "free" Gantt chart tools aren't really free. They cap you at one project or 60 tasks, hide export and the critical path behind an upgrade, and make you create an account before you can even try them. We wanted the opposite: open the page, build your chart, export it, done.
gantts.app gives you the full toolkit, drag-and-drop scheduling, task dependencies, milestones, phases, automatic critical path, and export to PDF, PNG, Excel and PowerPoint, with no sign up and no limits.
Privacy first
Because there's no account, there's nothing to hand over. Your project is created and saved right in your browser using local storage. We don't upload your plans to a server, and we don't require your email. You can also export a JSON backup or a shareable link whenever you want to move your data.
How is it free?
gantts.app is a lightweight static web app, there's no expensive backend to run, so we can keep it free. The running costs are covered by ads, through Google AdSense. We don't sell your data, and because your plans never leave your browser there is nothing about them to share; the details are on the privacy page. If it saves you time, the best thanks is to share it with a colleague or link to it from your blog.
