App backends

Here is a list of open-source alternatives to Firebase (ready-made backend for your app), from Open Source Everything (CC BY-SA 4.0): - Supabase (Apache-2.0, https://github.com/supabase/supabase; replaces fully): Supabase is a backend platform built on the Postgres database that gives apps login, data storage, file storage and automatic APIs. It is for developers building web, mobile and AI applications. - PocketBase (MIT, https://github.com/pocketbase/pocketbase; replaces fully): PocketBase is a free, open-source backend that bundles a database, user and file management, an admin dashboard, and a simple API into one program. It is for developers who want to build apps without running a separate server setup for each piece. - Appwrite (BSD-3-Clause, https://github.com/appwrite/appwrite; replaces fully): Appwrite is a backend platform that handles login, databases, file storage, serverless functions, messaging and realtime updates so app builders don't have to run those parts themselves. It is aimed at developers and the AI coding agents they use, and it can be used as a hosted cloud service or self-hosted with Docker. - Nhost (MIT, https://github.com/nhost/nhost; replaces fully): Nhost is an open-source backend for web and mobile apps, giving developers a database, user sign-in, file storage and a GraphQL API in one package. It is aimed at developers who want an alternative to Firebase that they can host themselves or run on Nhost's hosted platform. - Kuzzle (Apache-2.0, https://github.com/kuzzleio/kuzzle; replaces fully): Kuzzle is a ready-made backend server that handles common app needs such as data storage, user logins, and live updates. It is aimed at developers who want to build web and IoT applications faster. - Encore (MPL-2.0, https://github.com/encoredev/encore; replaces partly): Encore is a TypeScript and Go framework for writing backend code in which you declare databases, queues and file storage, and its open-source tools run them on your computer or package the app for self-hosting with Docker. Automatic setup in your AWS or Google Cloud account uses Encore's hosted platform, and it is aimed at developers building server-side apps. - AceBase (MIT, https://github.com/appy-one/acebase; replaces partly): AceBase is a database that stores app data and sends live updates to apps when that data changes. It is aimed at developers who want a Firebase-style database that they can run themselves on Node.js, in the browser, or on their own hardware. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
