I got tired of developer tools that want an account, a credit card, or a pile of ads before they'll format ten lines of JSON. So I built my own set and put them in one place. There are 112 of them, they are free, and none of them needs a signup.
Here is what's inside, grouped by the job you're usually doing.

Why bother?
Every tool here exists because the alternative was too bloated, too expensive, or hidden behind a paywall. The whole collection lives on one page: debasisbhattacasisbhattacharjee.com/tools/)
Which tool do you keep reaching for that I se comments and I'll look at building it.
