We got annoyed with having to use those 1990s-looking websites covered in ads anytime we needed to convert data (e.g. PNG to data URI). So we set out to build a set of these tools with a better developer experience.

We started by making the tools we use ourselves. Any time a Jam engineer needed a tool, they'd send it in our #project-dev-utilities Slack channel. Eventually we had 14 tools!

Then we got our first community contribution! Thanks Cassidy Williams for an awesome .env to Netlify.toml converter. And a couple weeks ago, we launched the site so anyone can use the tools, all client-side, free, and open-source.

Since then OSS contributors have added 4 more dev utils 🔥 - so cool. If you'd like to contribute a tool, we will send you a hat and probably a pizza too!

Are there any other tools that you wish existed or are there any other tools that you've made for yourself like this? Let us know! We'll be adding new tools regularly, so check back for more.

P.S. We’re hiring engineers and if you like building dev tooling, that’s our Jam and we’d love to chat: jam.dev/careers
