Vaultrice – A real-time key-value store with a localStorage API▲43
Hi HN, I'm Adriano, one of the makers of Vaultrice. I'm excited (and a little nervous!) to share what we've been building. For years, we found ourselves in a frustrating loop: whenever we needed a simple real-time feature—like a "who's online" list, a collaborative app, or just sharing state between a marketing site and our main app — we'd end up spending days setting up the same stack or discarded to do it.

Phase – open-source encryption and key management for developers▲9
Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…
