Tools improved

The main browser tools were upgraded into practical utilities:

  • Headers inspector now shows summary, cache policy, security headers, duplicates, and recommendations.
  • Security headers generator generates plain headers and ready-to-use Nginx add_header lines.
  • JSON formatter supports format, minify, sort keys, copy, and structure summary.
  • CIDR calculator supports IPv4 and IPv6.
  • Base64 codec supports Base64 and Base64URL with Unicode.
  • URL codec supports full URL and component modes.
  • JWT decoder shows header, payload, time claims, and warnings without signature verification.
  • Regex tester shows matches, groups, indexes, and summary.

Documentation became more practical

The main reference pages were rewritten:

  • Quickstart;
  • Safe deploy checklist;
  • Troubleshooting;
  • curl cheatsheet;
  • Cache-Control;
  • Content Security Policy;
  • OpenSSL checks;
  • Let’s Encrypt renewal;
  • TLS fallbacks.

Pages now focus on what to check, which commands to run, what result to expect, and when to stop.

A unified site structure was added

The site now uses a single catalog for docs and tools. Lists are generated from shared structure instead of scattered manual blocks.

What changed:

  • docs are grouped by category;
  • tools are grouped by task;
  • breadcrumbs were added;
  • internal pages now have an “In this section” block;
  • category links in breadcrumbs point back to the relevant catalog section.

Local filtering was added

/en/docs/ and /en/tools/ now include a local filter.
It searches title, description, slug, and tags.

The filter runs in the browser and does not send requests anywhere.

Homepage was improved

The root page now opens as a Russian landing page.
The homepage acts as an entry point into the reference: quickstart, docs, tools, and common tasks.
