Why we built six tools instead of sixty
Most "online tools" sites work the same way: grab a list of vaguely related keywords, spin up a near-identical page for each one, pad it with generic paragraphs, and let search traffic do the rest. You've probably landed on a dozen of them without noticing — same layout, same three sentences reworded six different ways, an ad wedged above the one input box that actually matters.
DevKit Forge is a deliberate reaction to that. We picked six tools we actually reach for — a JSON formatter, Base64 encode/decode, URL encode/decode, a JWT decoder, a regex tester, and a hash generator — and built each one properly instead of building sixty of them badly.
What "properly" means here
Every tool runs entirely as client-side JavaScript. Nothing you paste into any box on this site — a JSON payload, a JWT from a production system, text you're about to hash — is transmitted anywhere. There's no backend processing your input, because there doesn't need to be. Your browser is capable enough to format JSON, compute a SHA-256 hash, or test a regex pattern on its own, and doing it that way means there's nothing to log, nothing to leak, and nothing to wait on.
Each tool page also explains its own mechanics — not just "paste text here," but what the browser is actually doing when you click the button, why certain edge cases behave the way they do, and where the tool's limits are. The JWT decoder tells you plainly that it doesn't verify signatures, and why that's the right call rather than a missing feature. The hash generator tells you MD5 and SHA-1 aren't appropriate for password storage, even though it's happy to compute them for checksums.
Who's behind it
DevKit Forge is run by a small team who spend most of the working day in the same kinds of tools this site provides — decoding a token to debug an auth issue, reformatting a JSON blob dumped from an API, checking a regex before it ships in production code. We built the site we wanted to use ourselves.
What we don't do
We don't ask you to sign up. We don't store the data you paste in — we can't, since it never leaves your browser. We don't pad pages with filler to hit a word count, and if a tool page here feels a little dense, that's because we'd rather explain something real than write three more paragraphs of nothing.
