Tools

curl command builder
Pick any of the 27 protocols curl speaks, fill in protocol-aware fields, and get the exact command with every flag explained and safety warnings surfaced. The inverse of the HTTP request translator: that one reads a command, this one writes it.
HTTP request translator
Paste a curl command and get it explained flag by flag, then translated to fetch, a raw HTTP request, HTTPie, and Python requests. Local and offline; the command is decoded in your browser and nothing is sent or run.
Regex Toolkit
Test, explain, and debug regular expressions with live matches and a backtracking-risk check.
Sorting Algorithm Stepper
Paste a small list of numbers, pick a strategy - bubble, selection, insertion, merge, or quick - and watch the algorithm think: every comparison, every swap, one WHY line per move, with live comparison and write counters that make Big-O growth tangible.
URL Inspector
Dissect any URL into its named parts: scheme, host, port, path, query parameters, and fragment. Decodes percent-escapes and internationalized hosts, and flags credentials and other issues. Runs entirely in your browser.
