Documentation

DevHub is a free, local-first workspace for recurring developer transformations.

Using tools

Choose a tool, enter data, select an operation when available, then run it. Results can be copied or downloaded when the format supports it.

Processing model

The current 24 tools execute deterministic processing in the browser. Favorites contain tool identifiers only. Inputs and outputs are not saved by default.

Tool boundaries

Validation messages describe malformed input. JWT decoding does not verify signatures, SQL and cron support are intentionally basic, and Markdown supports a documented safe subset.
