Meta tag generation, SERP snippet previews, keyword density analysis and robots.txt building — practical on-page SEO checks that run entirely in your browser.
The tools
Ordered by how often they are used. Every one is free and runs in your browser.
Background
Most SEO platforms sell you data about other people's websites. The parts that reliably move rankings, however, are on your own pages: a title that fits Google's pixel limit, a description that earns the click, headings in a sensible order, and content that covers the topic without stuffing keywords.
These tools focus on exactly those on-page fundamentals. They need no API key, no crawl budget and no subscription, because everything they analyse is text you already have.
Use the SERP preview before publishing to see how a title and description will actually render in search results, then run the keyword density check to confirm your content reads naturally rather than repetitively. Both take under a minute and catch the mistakes that cost clicks.
