API and debugging tools speed up building and testing web APIs — test regular expressions with live highlighting, deep-diff two JSON objects, parse and edit URL query strings, look up any HTTP status code, and preview meta tags. Everything runs in the browser with instant feedback and no setup.
This cluster targets the inspect-and-verify loop of API work. Validate a regex pattern before shipping it, compare an expected and actual JSON response key by key, decode a tangled query string into an editable table and export it as JSON or curl, reference the meaning and typical use of every HTTP status code, and check how a page renders in Google, Open Graph, and Twitter cards. No accounts, no rate limits, no waiting on a remote service.
Preview how your page looks in Google search, Open Graph, and Twitter cards — with HTML output.
Compose URLs from protocol, domain, path segments, query params, and fragment — with colored output.
Deep compare two JSON objects — visual line diff and per-key summary of what changed.
Write a regex pattern, set flags, and test it against any string — matches highlight in real time.
Every HTTP status code explained with description and example use case — searchable.
Decode and edit URL query strings — live table, JSON export, curl format.
No. The regex tester, JSON diff viewer, query parser, and other debug tools all run locally in your browser. Your patterns, payloads, and URLs are never transmitted to a server.
Yes. The Regex Tester highlights every match in real time and supports flags such as global, case-insensitive, and multiline, while showing capture-group results as you type.
It performs a deep comparison of two JSON objects, showing a visual line diff plus a per-key summary of added, removed, and changed values — useful for verifying API responses.
Yes. It lists every standard HTTP status code with a plain-English description and example use case, and is fully searchable so you can jump straight to 401, 422, or 503.
