Everything for WordPress, web development — and beyond

16 free tools for site owners and web developers

We are the editors, bloggers and web developers behind SDStudio. Every day we write posts, move sites to new domains, dig through somebody else’s .htaccess after a 500, prepare images for publishing and do plenty of other web work. Instead of hunting for yet another online service every time, we built our own toolkit — and opened it to everyone.

  • The tools never go online. Your data never leaves the tab: everything is computed on the page, in your browser.
  • No sign-up, no limits. No “leave your email”, no watermarks, no paid tiers, no processing queue.
  • The tools store nothing. No localStorage, no cookies: close the tab and whatever you typed is gone for good.
  • They explain, not just calculate. Every tool shows what is happening and why — you can actually understand it, not just press a button.
  • Honest wording. Where a tool looks for problems it says “our checks found nothing”, never “all clean”.
  • They work offline. Once the page has loaded you no longer need the internet — the work happens locally, inside the page.

Everything you end up doing by hand in the database and the console: moving to a new domain, WP-CLI commands and the date format for your theme.

When the site returns a 500 or a file refuses to upload — start here.

Redirects after a move, language versions and schema.org markup — the things that affect search results, and the things where a mistake is easy to miss.

The routine that eats the most time: moving data from one format to another without breaking the escaping.

The two most common reasons for a heavy page — uncompressed images and YouTube embeds. Both are cured here.

No tool sends what you type to our server or to any third party — everything is computed in your tab. The page itself, like every other page on this site, counts views and uses Google Analytics: that covers your visit, not what you entered into the tool. The whole set is free, with no sign-up and no limits.
