Developer & Design

Formatters, encoders and generators that save a trip to the terminal.

About Developer & Design

Developer & Design gathers the small utilities that would otherwise send you to the terminal or a random website: formatters, encoders and decoders, colour and CSS helpers, and generators. They are quick, dependable, and run locally, so you can format, convert or generate without leaving the browser or exposing your data.

Who these tools are for

Developers, front-end and web designers, and anyone who occasionally needs to format JSON, encode a string, pick a colour, or generate a value without spinning up tooling.

Why use them

Fast, focused tools that do one job well and get out of your way.
Your code and inputs stay on your device — nothing is uploaded to a server.
No sign-up, no rate limits, and no ads injected into your workflow.
