Instant Sitemap vs Octopus.do

People searching for "sitemap tool" land on both Instant Sitemap and Octopus.do, but these tools have almost nothing in common. Octopus.do is a visual sitemap planning and wireframing tool for UX designers and website planners. Instant Sitemap validates XML sitemaps for search engine optimization. Same word -- "sitemap" -- completely different meanings.

The Quick Version

Octopus.do creates visual diagrams of website structures for planning purposes. Think flowcharts and wireframes showing how pages connect to each other. Instant Sitemap validates XML sitemap files that tell search engines which pages exist on your site. If you're planning a website's information architecture, you want Octopus.do. If you're checking whether your XML sitemap is valid and your URLs work, you want Instant Sitemap.

Feature Comparison

How Octopus.do Works

Octopus.do is a clean, well-designed tool for planning website structures visually. You create a diagram that shows the pages of a website and how they relate to each other -- homepage at the top, main navigation sections branching off, sub-pages below those, and so on.

It's genuinely good at this. The interface is intuitive, you can drag and drop pages, add annotations, create multiple levels of hierarchy, and even add basic wireframe content to each page. Teams use it during the planning phase of a web project to map out information architecture before any code gets written.

Octopus.do also supports collaboration -- you can share your visual sitemap with team members, clients, or stakeholders, making it useful for getting alignment on site structure before development begins. You can export the diagrams to PDF or image formats for presentations and documentation.

What Octopus.do doesn't do is anything related to XML sitemaps. It doesn't generate XML files, it doesn't validate them, and it doesn't check URLs. It operates in the design and planning phase of a web project, not the technical SEO phase.

How Instant Sitemap Works

Instant Sitemap operates in an entirely different world. It takes an existing XML sitemap file -- the kind that lives at yoursite.com/sitemap.xml and gets submitted to Google Search Console -- and validates it:

• XML syntax -- is the file well-formed XML with proper encoding and structure?
• Protocol compliance -- does the sitemap follow the sitemaps.org specification?
• URL status codes -- does every URL in the sitemap actually resolve, or are there 404s, redirects, and server errors?
• Size and count limits -- is the sitemap within the 50,000 URL and 50MB limits?

There's no visual component, no wireframing, and no site planning. It's a technical validation tool for a technical file format.

When to Choose Instant Sitemap

Our Honest Take

There's not much to compare here because these tools serve completely different purposes. The only reason people encounter both while searching is that the word "sitemap" spans two different concepts.

Octopus.do is a solid visual planning tool. If you're designing a website's information architecture, it does that job well with a clean interface and useful collaboration features. It has nothing to do with XML, search engines, or URL validation.

Instant Sitemap is a technical validation tool for XML sitemap files. It checks whether your sitemap is valid, whether the URLs in it work, and whether it complies with the protocol that search engines expect. It has nothing to do with visual design or website planning.

If you landed on this page trying to figure out which tool you need, the answer depends on your question. "How should I organize my website's pages?" -- Octopus.do. "Is my sitemap.xml file correct and are my URLs working?" -- Instant Sitemap. If you need both, you'll use them at very different stages of your project.
