Code is formatted entirely in your browser. The editor and formatter are self-hosted by KivTools and do not send a snippet to a remote API.

The enhanced editor loads only on this page. If it cannot start, the same local formatter stays available in the fallback field.

Formatted output

Formatting changes whitespace and layout; always retain a project copy before applying broad code transformations.

A local formatting desk for common web formats

Use the workspace when you need a readable diff or a quick paste-and-format result. The editor does not execute code, install dependencies, or expose private snippets to a third-party formatter.
