Curated List of SEO and Data tools

Welcome to the directory of SEO and data tools. This collection contains over 700 items: advanced software, cloud solutions, small utilities, browsers, and browser plugins. This list is focused on SEO, data, cellular automata, or fractals. Every tool has its category like performance, crawler, monitoring, alerting, or data visualization.

Use the options to sort and order by name or category. The best is to use the Search field. Input any keyword to get only tools from the desired category. For example, try typing words like security, performance, or crawler.

This list is regularly maintained and expanded. If you find any mistake or you are missing some vital entry, please scroll to the bottom of this page and leave a message via the contact form.

Some of the tools are marked with an icon in column Top. This icon means it's a mature, premium, and advanced software suitable for professional usage. Dead and discontinued items are striped of hyperlink and moved to the end of the list. Last but not least, poorly executed, unsafe, or not very useful tools receive nofollow attribute, warning mark and are also pushed to the end of the list. It's a decision of the database author. Everything is explained at the FAQ section below the table.

FAQ


It's a curated list of tools. Mostly for SEO and data. It contains several hundred tools. This enormous catalog began its life as a simple list for personal use. The first items were saved approximately in the year 2015. Then the list developed and slowly grew into a database. And the database was transformed into an extensive public catalog you can now enjoy.
