24 alternatives to RemoteStorage – sync localStorage across devices and browsers

Hey HN! Wanted to share a new library and server I've recently been working on called remoteStorage. When building frontends with Javascript, the native localStorage API is super useful for keeping track of state between sessions in the same browser, but it's not as good a solution when your data needs to be shared across multiple devices or browsers. For instance, let's say you want to show a welcome modal to all new users that sign up for your product. If you use localStorage to track if a user has already seen this modal, your users will end up getting the experience repeatedly every time…

RemoteStorage is a JavaScript library and server that extends localStorage functionality across multiple devices and browsers. It uses the same API as the native localStorage, allowing developers to sync application… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    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. Setting it up, it always involved wiring together a database, a WebSocket server, an API, and managing the connection state. It felt like massive overkill for what we were trying to…

    ServBay▲399

    Hello HN, I’m one of the creators of ServBay. I built this because I got tired of the cognitive load required just to start coding. On my Mac, it was a fragile mix of Homebrew services and asdf conflicts. On Windows, managing PATH variables and fighting with Docker Desktop's resource usage was equally frustrating. I missed the simplicity of the MAMP/XAMPP era, but I needed to support modern stacks (Go, Rust, Node, etc.). What it is: ServBay is a native local development environment for both macOS and Windows. It is not a wrapper around Docker or VMs. It bundles everything you need into…

    Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

    Hey HN, I'm Zach, founder of Portal. Portal lets you share a live sandbox browser session as a link. Try it here: https://www.makeportals.com/try Instead of asking someone to sign up, install software, or book a demo for user research, onboarding, or sales, you send a link and they interact with the real product in a sandboxed browser environment, then you get session replays. Each viewer gets a fresh remote browser instance that starts from a defined state (URL, cookies, extensions, local files, etc). Sessions are isolated and expire automatically. The sessions have…
