    Bi-directional sync between Postgres and SQLite▲356

    Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

    Dynbox.app▲125

    Hey HN, This is my first ever launch! I built a productivity tool that helps you organize your files in bulk, quickly and easily. Instead of manually organizing files, which can be tedious and time-consuming, you can now ask an AI agent to do it for you. Right now, Dynbox integrates with Google Drive, and I’m rapidly working on support for local file systems as well. I’d love to get your feedback!

    Sink – Sync any directory with any device on your local network▲151

    i made sink. it's a simple little tool that continuously syncs folders between 2 devices. no cloud, no email, flash drives, no bs. it just uses your local wifi. run it on your machines, tell them to trust each other, and you're set. and if you manage to edit the same file at once, it handles the conflict and saves both copies. for anyone who just wants to get files from point a to b without the headache. hope it makes your life a bit less annoying. github: https:&#x2F;&#x2F;github.com&#x2F;sirbread&#x2F;sink binary:…

    Bitbox.co – Cloud Storage for Developers▲86

    I've decided to bite the bullet and release Bitbox.co and get some feedback. I've been coding for years and one of the things I constantly see companies do is write and rewrite a document storage system, so I decided to write one for them. Bitbox.co uses cloud storage (currently Azure) to store documents but can be coded to use any cloud service. Documents can be public or private and URLs to that document can be used directly in HTML. There are currently a list of WebAPIs for developers to use as a tool, or build an entire system around. This is an MVP and it's simple. Upload a file, get a…
