I got tired of writing client proposals in Google Docs that looked amateur. Every SaaS alternative charged $20-50/month for what's essentially a PDF template. So I built ProposalForge — one HTML file, 30KB, zero dependencies.
The Stack (It's Just HTML)
No React. No Vue. No build step. Just vanilla HTML, CSS, and JavaScript.
- CSS custom properties power a 3-template theming system
- @media print stylesheet handles PDF export — no library needed
- localStorage manages draft persistence
- Smart pricing calculator with auto-totals, discounts, and tax
Why Single-File?
Because nobody wants to install software or create an account to write a proposal. You download the file, double-click, and start working. It works 100% offline — useful when you're at a client site with no internet.
The Templates
Three themes (Modern, Minimal, Creative) that you can switch between instantly. The CSS custom property system means each template is just a different set of variable values.
What I Learned
- You don't need a framework for a polished UI — CSS variables are incredibly powerful
- @media print is underrated — perfect PDFs with zero JavaScript
- Single-file tools are a real business model — Gumroad makes distribution trivial
I'm selling it for $12 one-time on Gumroad. No subscriptions, no accounts, no internet required after download.
Would love feedback from other indie makers here — especially on pricing and feature ideas!
