Try Ganttastic without an account

1. Open ganttastic.com and click Build without an account, near the foot of the home page and the pricing page. You can also go straight to ganttastic.com/app.
2. Ganttastic starts a guest session automatically. No form, no email address, nothing to install.
3. You land on Start your project, where View a sample project opens the Demonstration Project, a small sample plan you can start editing right away.

Generate my first plan, the main button on ganttastic.com, works differently. AI features need an account, so it opens the sign up form first, and once you are signed in it opens the AI project wizard. If you sign up with email, the wizard opens after you verify your address. Going to ganttastic.com/demo opens the same guest app as ganttastic.com/app.

A banner across the top of the app reminds you that your work is saved in this browser only, with Sign up and Sign in buttons. You can dismiss it. The first time you add a task in a browser tab, a toast also says Your work is stored in this browser only and offers Sign up. It appears once per tab, and other edits do not trigger it.

Guest mode is the real app with real editing, inside some honest limits:

Guest mode has no project limit. Your plan’s active project limit applies when you sign up or sign in: 2 on the free Team Member plan. Guest projects over the limit are moved to Completed Projects, and a Project Limit Reached toast names them, so nothing is lost. Restore one when you free a slot.

Export formats are covered in export your project, and the full tier comparison lives in plans and pricing.

Yes, within one browser. Guest projects are stored in your browser’s local storage on your device. Close the tab, restart the computer, come back next week: your projects are still there, as long as you return in the same browser on the same device.

Your guest work is lost if:

• you clear the browser’s site data or cookies for ganttastic.com,
• you worked in a private or incognito window and closed it, or
• you open Ganttastic in a different browser or on a different device (guest data never leaves the machine it was created on).

Guest mode keeps working offline. Your edits save in this browser as usual, and nothing waits to be sent anywhere, because guest work never goes to a server.

The Demonstration Project is a prebuilt sample plan so you can see a working schedule before creating your own. It holds three phases with sub-tasks and dependencies, three milestones, five resources, and two holidays. Its dates are set around today, so some work shows as done and the rest lies ahead.

The sample does not open by itself. While you have no project of your own, the Start your project screen offers View a sample project, which opens it. It is never listed in the sidebar. The sample opens in the Full Project view, which shows the whole plan at once; once you switch away, choosing Full Project again needs the Project Manager plan.

A Demonstration Project banner sits above the chart, with a Sign up button for guests. Its Back to start button, or your browser’s Back button, returns you to the Start your project screen, and reloading the page lands there too. As a guest you can edit the sample freely, and your changes stay in your browser like the rest of your guest work. The sample cannot be shared.

After you create an account, the sample behaves differently. While you own no projects, View a sample project opens the Demonstration Project as a read-only sample. Your first edit opens the Save a copy to keep your changes? dialog; click Save a copy and your edit lands in a real project named Demonstration Project (copy) that belongs to you. To copy the sample without editing it first, click Save as new project in the banner. Once you have a project of your own, the app opens that project instead of the Start your project screen, and the sample is no longer offered.

1. Click Sign up in the guest banner, or Sign in if you already have an account. The Sign in to save your projects button in the sidebar’s Guest Mode panel works too.
2. Create the account with email or Google, or sign in to your existing account. The full walkthrough is in create your account.
3. Projects you created as a guest are imported into the account automatically and start syncing to the cloud. When you sign in, the Signed in successfully! toast adds "Your guest project is now in your account."

Projects over your plan’s active project limit are moved to Completed Projects, as described above. If the import cannot finish, a toast says your guest projects were not added and offers Try again. They stay in this browser until you try again or sign out; signing out removes them.

Two things do not carry over: edits made to the Demonstration Project sample (only projects you created yourself migrate) and anything left in a different browser. Sign up or sign in from the same browser where you did the work. On a shared computer, the guest projects in that browser go to whoever signs in next.

Two kinds of sign in do not import guest projects: signing in to an account that has two-factor authentication turned on, and a Google or single sign-on sign in to an existing account that continues in the same tab because the browser blocked its popup window.
