Goodies

Small tools for developer questions that come up during real work.

Goodies are browser-first tools for syntax behavior, API responses, responsive CSS, scheduled jobs, campaign links, page metadata, and quick data inspection. Each one gives a direct answer, a copyable output, and the caveat that usually gets missed.

Browser-firstNo account, no upload flow, no pasted-work collection.

Answer-firstThe result appears before the long explanation.

Production-awareEvery tool includes caveats, checks, and failure notes.

What belongs in Goodies?

A goodie must remove friction from an actual developer task. It needs a clear input, a useful result, a mobile-safe interface, and enough explanation to prevent a copy-paste mistake. Broad generators and tools that only decorate input do not make the cut.

SpecificOne question, one clear workflow, one copyable result.
ReadablePlain language first, references and caveats second.
Useful after handoffIncludes the notes another developer needs to safely reuse the output.
