    Project mention: Cheese Paper: a text editor specifically designed for writing | news.ycombinator.com | 2026-05-30

    Project mention: I turned my Trilium docs into an AI-assisted site with one JS file | dev.to | 2026-05-04

    I'd built an internal documentation site in Trilium Notes — about 30 notes covering product, marketing, and operations stuff. It was for non-technical teammates who needed to answer questions from developers about the platform.

  5. RxDB

    The local-first database that runs on every JS runtime and replicates with your existing backend - no vendor, no lock-in - https://rxdb.info/

    Project mention: Offline-First Landscape – 2025 | news.ycombinator.com | 2025-08-29

    I’m doing offline-first apps at work and want to emphasize that you’re constraining yourself a lot trying to do this.

    As mentioned, everything fast(ish) is using SQLite under the hood. If you don’t already know, SQLite has a limited set of types, and some funky defaults. How are you going to take this loosey-goosey typed data and store it in a backend database when you sync? What about foreign key constraints, etc., can you live without those? Some of the sync solutions don’t support enforcing them on the client.

    Also, the SQLite query planner isn’t great in my experience, even when you’re only joining on ids/indexes.

    Document databases seem more friendly/natural, but as mentioned indexeddb is slow.

    I wish this looked at https://rxdb.info/ more. They have some posts that lead me to believe they have a good grasp on the issues in this space at least

    I'm a senior iOS engineer at Anytype, fully responsible for the open-source iOS app. I've been using a coding agent daily for about 8 months now, and I recently pulled my Task tracker data to see what happened to my productivity.
