20 free dev tools — which ones actually got used last week

hit 20 tools on my free dev tools site today so figured i’d share what actually got used last week. some of the data surprised me.

here’s the quick rundown:

most used tools (by page views):

1. JSON Formatter — no surprise, it’s on the homepage now
2. Regex Tester — the preset pattern library got a lot of clicks, especially the email regex
3. JWT Decoder — way more usage than i expected, guess everyone’s debugging tokens
4. Mock Data Generator — new addition, people seem to like the API response format

least used (barely touched):

• Password Generator
• HTML Entity Encoder
• UUID Generator

takeaway: the “boring” tools (JSON, regex) carry the site. the generators are nice-to-haves but nobody comes just for them.

i also added an inline JSON formatter right on the homepage — paste and format without clicking through. honestly should’ve done that from day one. session time went from 14s to around 40s after that change.

site’s at https://quickdev.cc if anyone wants to look. still figuring this out as i go — if you run a tools site or have opinions on which tools to add next, i’m all ears.

also: the amount of sites that send your JSON payload to their server for “formatting” is wild. everything on this runs client-side, your data never leaves your browser.
