Scync

What it does

The secure home your secrets actually deserve. Scync is an open-source, zero-knowledge vault for solo devs tired of losing API keys and secrets. Say goodbye to chaotic flat lists. Organize credentials by project, drag-and-dropenv files to instantly import keys, and safely track numbered 2FA & recovery codes. Backed by client-side AES-256-GCM encryption and biometric unlock, your data stays perfectly organized and architecturally impossible for anyone else to read, even servers.

The open-source, zero-knowledge secrets manager built for developers. Store API keys, recovery codes, and environment variables securely with client-side encryption.

  I had this backup code working reliably for years, using local file system, vps/dedicated server, or remote storage for backup, then I finally get time to wrap README, iron few missing switches and publish. Should be production ready and reliable, so it could be useful to others. Contributors are welcome.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
