Put this measurement in your README

A badge carrying how many items this registry publishes, enumerated nightly from its own registry.json. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.

BlockDex badge

[![BlockDex](https://toolproof.kynth.studio/badge/blockdex/moco.svg)](https://blockdex.kynth.studio/registries/moco)

Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:

Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.

The studio list

One product, taken apart, once a month

Kynth Studios pulls one shipped product open every month — what it does, what it cost to build, what the pipeline behind it looks like, and what the numbers did. One email a month, nothing in between.

Double opt-in — we send one confirmation link and nothing else until you click it.
