Zero-knowledge file/paste/poll/chat sharing for anyone who canโt trust Drive/Slack/WhatsApp with sensitive stuff. Client-side AES-256-GCM; keys live in the URL fragment (server never sees content or metadata); no accounts/PII/phone numbers. Runs on Cloudflare Workers with region pinning. Pricing: pay-per-use credits (per GB uploads, per secure paste/chat/poll), bulk credit packs for frequent users. Target: lawyers/healthcare/M&A contractors/agency folks needing one-off or short-lived private exchanges; supports group chat but no team workspace. Moat: true zero-knowledge (only encrypted blobs to subpoenas), compliance-friendly regions, link-based flows with no signup

Privsen's answer
Zero-knowledge by default: client-side AES-256-GCM, keys in the URL fragment, no accounts/PII/phone numbers, no metadata logging. We literally cannot decrypt your content or comply with data requests beyond handing over encrypted blobs.

I've set it all up with the OpenAI API using the gpt-5-chat-latest model. When I click on any file and... - Source: dev.to / 3 months ago
Nextcloud and ownCloud share a common ancestor. In 2016, Nextcloud's founder (Frank Karlitschek, who also founded ownCloud) forked ownCloud to create Nextcloud, taking most of the developer community with him. Since then, the projects have diverged significantly. - Source: dev.to / 5 months ago
Previously Nextcloud [1], currently bewCloud [2]. Full disclosure: I created bewCloud as a simpler, faster, and modern alternative to Nextcloud.

This is the same energy behind projects like Gaia-X, Nextcloud, and the open-source revival happening across the continent. Itโs not nostalgia for on-prem servers itโs a philosophy: control what you depend on. - Source: dev.to / 9 months ago
