Developer tools

Small utilities for the chores that come up while you build software

Developers spend a surprising amount of time on side tasks: checking whether a JSON payload is valid, working out why a regular expression does not match, decoding a cron schedule, or turning a curl command copied from browser devtools into fetch code. This category collects those helpers so you do not have to write a throwaway script each time.

The tools fall into a few families. Minifiers and formatters clean up HTML, CSS, JavaScript, SQL and XML. Data tools convert and compare JSON, CSV and environment files, and can generate TypeScript types or a JSON Schema from a sample. Config generators write files such as robots.txt, .gitignore and Open Graph tags.

Front-end developers, backend engineers, QA testers and technical SEO staff all end up here, usually in the middle of debugging. Because each tool takes pasted text and returns text, the output drops straight into your editor, a ticket or a pull request.

Common questions

Is it safe to paste production data into these tools?

Treat any pasted data with the same care you would give a public paste site. Remove real tokens, passwords and personal records first, and use sample or masked values whenever the goal is only to check structure or syntax.

What is the difference between minifying and beautifying code?

Minifying strips whitespace and comments so files download faster, while beautifying does the opposite and re-indents code so people can read it. Minified code is meant for browsers and beautified code is meant for reviewers.

Can I generate types or schemas from real API responses?

Yes. Paste a representative JSON response into the TypeScript or JSON Schema tool and it infers the structure. Inference only sees the fields in your sample, so review the result for optional properties that did not appear.
