Hey Product Hunt! 👋 I'm the maker behind Solo OS. When you are handling unreleased client branding, financial data, or strict NDAs, the last thing you should do is upload those assets to a third-party server. Yet, the freelance industry relies heavily on cloud-based SaaS tools that do exactly that—and charge a $15/month subscription for the privilege. I wanted a professional, privacy-first alternative. So, I built Solo OS. It is a 100% client-side, zero-backend toolkit for freelancers. Built entirely on React, Vite, and local browser memory, your files and client data never leave your machine. Because there is no database hoarding your data and my server costs are exactly ₹0, I completely threw out the traditional SaaS subscription model. The Toolkit: Interactive Bento Proposals: Build stunning, modular HTML proposals where clients can toggle add-ons and watch the total price update dynamically. Local E-Signatures: Sign contracts and SOWs entirely client-side using HTML5 Canvas and in-browser PDF generation. The Local Watermarker (Free): Instantly tile "UNPAID DRAFT" across your images to protect your work, processed entirely on your GPU. Frictionless Invoicing: Generate professional PDFs with embedded payment links/UPI QR codes. The Business Model: No MRR. No account required. The watermarker is completely free, and you pay a tiny, flat fee (₹29) via a guest checkout only when you actually need to export a premium legal document. I would love to hear the community's thoughts on the zero-backend architecture and the interactive HTML proposal builder. Try running a heavy PDF through the local watermarker and let me know how it performs! Cheers!
