DevvyTool — Small tools, no installs.

What it is

A drawer of tiny developer utilities. The sort of thing you otherwise search for, land on a site with six ad slots and a cookie wall, and then paste your data into anyway.

Why it exists

Every one of these tools already exists, badly. They load three megabytes of tracking to decode a base64 string. DevvyTool is the version that opens instantly and does the thing.

The interesting bit

Everything runs locally in the browser. That is not a marketing badge — it means the tool keeps working offline, and your input never leaves your machine, which is the only acceptable behaviour for a tool people paste real data into.

“The "I just need to do this one thing" drawer.”
