24 alternatives to FaynoSync Self-Hosted API for Automatic App Updates
This application is a simple API server for automatically updating client applications. It allows you to upload your application to S3 and set the version number. The client application can then check the version number against the auto updater service API. If the service has a newer version, it will return a link to the updated service, and the client application will show an alert. The API server is designed for straightforward and intuitive application management. It supports updating client applications both in the background and on-demand, depending on how it's implemented in the client…

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…

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! We've developed OpenAPI AutoSpec, a tool for automatically generating OpenAPI specifications from localhost network traffic. It’s designed to simplify the creation of API documentation by just using your website or service, especially useful when you're pressed for time. Documenting endpoints one by one sucks. This project originated from us needing it at our past jobs when building 3rd-party integrations. It acts as a local server proxy that listens to your application’s HTTP traffic and automatically translates this into OpenAPI 3.0 specs, documenting endpoints, requests, and…

Hey HN, we're launching Outpost, an open-source, self-hostable component designed to handle outbound event delivery for SaaS/API platforms. If you're building a platform, you eventually need to send events to your users (think payment success, resource updates, workflow changes). Implementing this reliably—handling retries, monitoring, scaling, providing a decent dev experience for consumers, and managing tenants—becomes a significant, recurring engineering task that distracts from core product development. We built Outpost to offload that complexity. Outpost delivers events via…

Hey HN, We've been experimenting with a real-time, version-controlled NoDB for Deno & React called GoatDB. The idea is to remove backend complexity while keeping apps fast, offline-resilient, and easy to self-host. Runs on the client – No backend required, incremental queries keep things efficient. Self-hosted & lightweight – Deploy a single executable, no server stack needed. Offline-first & resilient – Clients work independently & can restore state after server outages. Edge-native & fast – Real-time sync happens locally with minimal overhead. Why We Built It: We needed something that’s…
