There is no hard limit. You can add as many events as needed. For very long timelines, the vertical layout works best as it scrolls naturally down the page.
Your timeline is stored in your browser's session memory only. It will be lost if you close or refresh the page, so export your work before leaving.

The right layout depends on how your audience will consume the content.
Vertical timelines work best for web pages where readers scroll top to bottom. They're ideal for blog posts, project histories, and documentation because each event gets enough space for detailed descriptions. Vertical layouts also adapt naturally to mobile screens.
Horizontal timelines are better suited for presentations, slides, and dashboards where you want a left-to-right flow. They're great for product roadmaps and release schedules where time progression from left to right mirrors how we naturally read calendars and Gantt charts.
Timelines are remarkably versatile. Here are some of the most common scenarios where a quick, exportable timeline makes a real difference:
Once you've built your timeline in this tool, click Export HTML. You'll get a self-contained HTML file with all styles inlined. There are two main ways to add it to your site:
Option 1 — iframe: Host the HTML file on your server and embed it with an <iframe src="your-timeline.html"></iframe>. This is the quickest method and keeps the styles completely isolated from your main stylesheet.
Option 2 — Direct embed: Copy the markup and inline CSS from the exported file and paste it into your page's HTML. This gives you more control over styling and removes the need to host a separate file.
A well-structured timeline communicates quickly. Here are a few best practices:
Desktop timeline tools like Microsoft Visio or OmniGraffle are powerful but heavyweight. They require installation, licensing, and often steep learning curves. Browser-based tools like this one give you 80% of the capability in 20% of the time — no install required, accessible from any device, and shareable via a simple URL.
For most developers, writers, and project managers, a free online timeline generator is more than sufficient for day-to-day needs.
