What this site is
DevSEOCraft is a collection of 15 free utilities for developers and technical SEOs. Each one solves a specific, narrow problem — decoding a token, checking a config file, previewing a search snippet — and each one runs entirely in your browser.
The tools are deliberately small. There is no dashboard, no account and no project to set up. You arrive with a problem, you paste something, you get an answer, you leave. That is the whole product.
Who builds it
DevSEOCraft is built and maintained by Pablo, who writes about building software and SEO systems in public as @fluyeporlaweb. It is a one-person project, not a company.
The tools come out of real work. Each one exists because it was needed while debugging something, and the alternatives all wanted an email address or wanted to send the input to a server.
Why everything runs client-side
The inputs these tools take are frequently sensitive: JWTs are live credentials, .env files hold API keys, and URLs can identify clients. Sending that to a server — anyone's server — to run a transformation that JavaScript can do locally is an unnecessary risk.
So no tool on this site uploads your input. There is no backend that receives it, which means there is nothing to log, leak or subpoena. You can verify this yourself: open your browser's network tab and use any tool. There are no requests.
How this is funded
The tools are free and will stay free. The site is funded by advertising and byaffiliate links to products we think are genuinely worth paying for. When a link is an affiliate link, it is labelled as one, and it never changes what a tool tells you.
Advertising is kept out of the way of the tool itself. If an ad ever sits between you and the thing you came to do, that is a bug — tell us.
Contact
Bug reports, tool requests and corrections are all welcome at hello@devseocraft.com, or on X at @fluyeporlaweb.
If a tool gives you a wrong answer, that is the most valuable message you can send. Include the input you used, if you can share it.
