I Just Launched My Free Email Signature Generator on Product Hunt

#productivity #javascript #webdev #showdev

I built SigCraft because every email signature tool I tried was either ugly, required signup, or slapped watermarks on everything.

So I made one that's 100% free, runs entirely in your browser, and just works.

What it does

Real-time preview as you type
Custom colors, fonts & separator styles
One-click copy for Gmail, Outlook, Apple Mail
Save & switch between multiple signatures
Mobile-friendly output

The tech

Zero dependencies. Pure vanilla HTML, CSS, and JavaScript. Static site on GitHub Pages. Your data never leaves your browser - signatures saved in localStorage. No backend, no database, no tracking. About 30KB total.

I went with inline CSS for signature output because that's the only thing that works reliably across email clients. If you've ever styled HTML emails, you know the pain.

Why I built it

I was setting up email for a new project and spent 20 minutes trying different generators. Most wanted an account. Some wanted my credit card before I could preview. Others generated signatures broken in Outlook.

This is a solved problem: form fields, HTML table with inline styles, copy button. Weekend to build v1.
