Hi Product Hunt! 👋 As someone who frequently handles sensitive documents, I’ve always been skeptical about uploading private files to cloud-based editors. Yet, installing 2GB+ of office software just to edit a doc feels overkill. That’s why we built this. By leveraging WebAssembly (WASM) and the OnlyOffice core, we managed to move the entire processing engine into your browser. What makes this special: True Privacy: Since there’s no backend, your data literally cannot be leaked to any server. Speed: It bypasses the "upload-process-download" cycle. Everything is local. Openness: We believe productivity tools should be transparent, so it’s 100% open-source. I’d love to hear your thoughts on the WASM performance and what features you’d like to see next! I’ll be here all day to answer your questions. Happy editing! 🚀
