About the HTML Preview
- What does the HTML Preview do?
- Render HTML in a sandboxed iframe. GeekTool runs the HTML Preview entirely in your browser — input never leaves your device.
- Is the HTML Preview free?
- Yes. The HTML Preview is part of GeekTool, a free suite of 50+ developer utilities. No sign-up, no ads inside the tool, no quotas.
- Does the HTML Preview send my data to a server?
- No. All processing is client-side JavaScript. Your input stays in your browser tab — we never see it.
