Your everyday developer toolkit.
Format, convert, inspect. The little tools that keep your work moving.
Choose a quantity and generate UUID v4 identifiers in one click.
Errors point to their location. Formatting preserves numeric values without rounding.
Small tools for everyday development tasks
An unreadable API response, a SQL query on one line, or a Base64 string you need to decode: open a tool, paste your input, and get your result. Devkit brings 17 free utilities into one consistent workspace. Live mode updates the output as you type, while manual mode lets you decide when to run a transformation.
Do I need an account?
No. Every tool is available without signing up. Copy the result, download it, or use it as your next input.
Is my data sent to a server?
All transformations happen in your browser. Devkit does not upload or save your input. Only your theme preference and favorite tools are stored locally.
