Parse Server

What is Parse Server?

Parse Server is an open source backend-as-a-service (BaaS) framework that runs on Node.js and Express. It gives mobile and web apps a ready-made backend — a database with auto-generated REST and GraphQL APIs, user authentication, file storage, push notifications, and server-side logic — that you host yourself instead of renting from a proprietary cloud.

What is Parse Server best for?

Parse Server is best for teams building mobile or web apps who want a full app backend without writing one from scratch — and without the vendor lock-in of a hosted platform. It’s a strong fit when you need auth, data, and push out of the box but want to keep control over where your data lives and what it costs. It began as the open-sourced core of Facebook’s Parse.com after that service shut down, and is now maintained by an independent community.

What can Parse Server do?

• Auto-generated REST and GraphQL APIs built from your schema, so you query data without writing endpoints.
• User authentication with sign-up, login, email verification, password reset, and social/OAuth logins.
• Live Queries for real-time, reactive data that pushes updates to clients as records change.
• Cloud Code — server-side JavaScript for custom business logic, triggers, and validation.
• File storage through swappable adapters: local filesystem, AWS S3, Google Cloud Storage, or MongoDB GridFS.
• Push notifications to iOS (APNS) and Android (FCM).
• Fine-grained access control with class-level permissions (CLP) and per-object ACLs.
• Choice of database — MongoDB or PostgreSQL — plus the separate Parse Dashboard web UI for managing data, users, and config.

Where does Parse Server fall short?

• Fewer built-in services than Firebase. Firebase bundles analytics, crash reporting, hosting, remote config, and ML features that Parse Server doesn’t; with Parse you assemble those from other tools.
• No multi-tenancy in a single instance. Each Parse Server maps to one app, so running many apps means running many instances rather than partitioning one.
• Cloud Code runs in the server’s own process, without the sandboxed isolation of managed serverless functions — a heavy or misbehaving function can affect the main server.

Is Parse Server free?

Yes — Parse Server is fully free and open source under the Apache-2.0 license, with no usage tiers, seat limits, or paid editions. Your only costs are the infrastructure you run it on (a server plus a MongoDB or PostgreSQL database). Managed Parse hosting also exists from third parties like Back4App if you’d rather not run it yourself.

What does Parse Server replace?

Parse Server stands in for hosted backend-as-a-service platforms — most directly Firebase and AWS Amplify. It covers the same core jobs (data, auth, storage, push, serverless logic) while keeping the backend on infrastructure you own, so you avoid per-read pricing and vendor lock-in.

FAQ

Is Parse Server open source? Yes. Parse Server is released under the permissive Apache-2.0 license and developed in the open by the Parse Platform community on GitHub, allowing free commercial use.

Can I self-host Parse Server for free? Yes. The software is free; you pay only for the server and database you deploy it on. There are no license fees regardless of app size or user count.

Is Parse Server a good Firebase alternative? For core backend needs — data, auth, file storage, push, and custom logic — yes, and it removes vendor lock-in. Firebase still wins on breadth of managed extras like analytics and crash reporting.

What do I need to run Parse Server? A Node.js runtime and either MongoDB or PostgreSQL for the database. The optional Parse Dashboard gives you a web interface to browse data and manage your app.
