What it does
HTML preview is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Render arbitrary HTML in a sandboxed iframe next to the source.
Because Hexkit is a native app rather than a web page, anything you paste into the html preview stays local — there are no uploads, no accounts and no telemetry. You can inspect and preview content even with the network turned off, which makes it safe for tokens, keys and production data.

How to use HTML preview
- 1
Open Hexkit and select "HTML preview", or press the command-palette key and start typing its name.
- 2
Paste or drop in the content you want to inspect. Render arbitrary HTML in a sandboxed iframe next to the source.
- 3
Read or copy the result. Everything is computed locally by Hexkit's Rust core, so nothing is ever uploaded.
Tip: the command palette opens any tool in one keystroke.
