   We built an end-to-end encrypted alternative to Google Photos▲1,180

   Hello HN, Over the last year we've been building ente[1], a privacy-friendly, easy-to-use alternative to Google Photos. We've so far built Android[2][3], iOS[4], web[5] apps that encrypt your files and back them up in the background. You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files. We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an…

   NoteCove▲82

   I built NoteCove because I wanted notes and tasks that sync across devices without the data going to a SaaS company. The sync works through files on your own iCloud Drive, Google Drive, or Dropbox — there's no NoteCove server in the sync path. The tricky part was making this reliable. I ended up using CRDTs (specifically Yjs) for conflict resolution, which handles the case where you edit the same note on your phone offline and your laptop offline — both edits merge without losing either. It has a full task management system alongside notes: custom states, kanban boards, parent/child…

   Unforget, the note-taking app I always wanted: offline first, encrypted▲274

   Hi HN! I created Unforget out of years of frustration with Google Keep and the lack of alternative that met all my needs. I hope you find it useful too! Features include: - import from Google Keep - offline first including search - sync when online - own your data and fully encrypted - Desktop, mobile, web - lightweight, progressive web app without Electron.js - markdown support - programmable with public APIs - open source [1] While I still use org mode for long-form notes with lots of code, Unforget has become my go-to for quickly jotting down ideas and to-do lists after migrating the…

   Matrix-CRDT – real-time collaborative apps using Matrix as backend▲320

   Hi HN! Matrix-CRDT connects the worlds of Yjs [1] (a proven, high performance CRDT) with that of Matrix.org [2]. It started as an experiment, asking myself; can we store "state updates of a datastore" in Matrix instead of chat messages? Now, I'm convinced it's actually a really powerful combination to develop real-time, collaborative software. I'm using it for a new project and so far didn't have to write a backend yet. Matrix takes care of a lot of stuff: Authentication, E2EE, federation, hosting, etc. - so I can focus on the client. I love the ideas of Local First [3] software. Personally,…

    Pg_CRDT – an experimental CRDT extension for Postgres▲296

    This is an experimental extension for CRDTs, pg_crdt: GitHub repo[0]. It supports Yjs/Yrs and Automerge. The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

    Collaborate on your YC Application with CRDT-powered forms▲22

    Hi HN, Like many of you here, this is not my first time applying to YC. Each time, my co-founder and I would copy the YC application to google docs to collaborate on it, then we copy it back to submit. This got us thinking - why can't we just collaborate on the YC application in the YC application? At one point I went down the CRDT rabbit hole and realized collaborative forms would be a great use of CRDTs, so I decided to build this out to an MVP. If you're curious about CRDTs (Conflict-Free Replicated Data Types) and how they differ from OT (Operational transformation, which is what powers…

    Hi! I built Lockbridge because encrypted file sharing and management are still too complicated in 2025.

    Muse 2.0 with local-first sync▲178

    Hey HN, I want to share with you something I and my four colleagues have been working on for the last several years. It’s a whiteboarding and notes tool called Muse[1]. We just released a 2.0 version which includes local-first sync. A little backstory: I’m one of the authors of the 2019 essay Local-first software[2]. (Past HN discussions[3][4].) The thesis is to reclaim some of the ownership over our data that we’ve lost in the transition from filesystems to cloud/SaaS. So I’m excited to bring CRDT technology “out of the lab” and into a commercial product as a chance to prove the value…

    Let's Seal – Let's Encrypt for document signing, free and self-hosted▲94

    TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…
