Developer tools
2 developer tools, included with Apexkit.
JSON, regex, diff, markdown, encoders, beautifiers — the small developer utilities you'd otherwise Google + cookie-banner-dismiss your way through.
Common use cases
What you can do with the developer stack
- Format minified JSON returned by an API.
- Test a regex against a corpus before deploying it to production.
- Diff two configs to spot the drift.
- Encode / decode URLs, Base64, JWT payloads.
- Generate UUIDs, hashes, slugs.
Why we bundled developer tools
Developer utilities are the most-Googled tools on the internet — every one of them sits behind a banner farm with three pop-ups and a newsletter signup. Apexkit's versions are ad-free, signed-in-free for one use per tool, and consistently styled. They run entirely in your browser; nothing is logged. The regex tester additionally lets you generate a regex from an English description via GPT-4o-mini if you're on Pro and above.
Frequently asked
Do you log my data?
No. Dev utilities are 100% client-side — your JSON / regex / diff content never leaves your machine. The English-to-regex generator does send the description (not the test corpus) to the OpenAI API, but only when you opt in by clicking 'AI generate'.
