Open tool →Every tool on this page is a single-purpose utility built around one question: what would I want to use right now if I were facing this problem? They are not SaaS products in disguise. They have no accounts, no dashboards, no usage limits, and no email captures. Type your numbers in. Get an answer. Leave.
If you are an in-house operator at a B2B company, a founder running marketing yourself, or a consultant working through a diagnostic, these are built for the shape of work you actually do. If you are a creative agency or analytics vendor, you are welcome to use them too, with the same terms.
Because they should be. Everything here is a tool I either built for my own work or wanted to exist and could not find a clean free version of. Free is also the right pricing for a tool that takes 10 seconds to use. There is no signup wall, no email gate, and no upsell to a paid tier hiding behind any of these.
No. Every tool runs entirely in your browser. The numbers, URLs, and inputs you enter never leave your device. The one exception is the Robots.txt Validator, which can optionally fetch a public robots.txt file from a domain you enter; that fetch is rate-limited and validated server-side, but no user input beyond the domain name is stored.
Yes. The outputs (keyword lists, allocation tables, audit scores, exported CSVs) are yours. The tools themselves are not redistributable as your own product, but the data they generate is.
Because that is the wrong shape for what these are. They are sharpening tools for working operators, not SaaS products. If a tool here becomes more useful as a paid product some day, I will say so honestly. Until then, they stay free and unauthenticated.
Yes, on an irregular cadence. New tools ship when I build them for my own work and decide they would be useful to others. Subscribe to the Tuesday Briefing to hear about new tools as they ship, or check this page periodically.
