Top Appwrite alternatives in 2026

Appwrite is an open-source Backend-as-a-Service (BaaS) platform offering features like authentication, databases, storage, and real-time functionalities, available as both a managed cloud service and self-hosted via Docker. Alternatives to Appwrite include Supabase, Firebase, PocketBase, and Northflank, each catering to different needs. Supabase, built on PostgreSQL, is a popular open-source option providing relational SQL databases, while Firebase, Google's proprietary BaaS, offers NoSQL databases and extensive mobile tooling but lacks self-hosting options. PocketBase is a lightweight, open-source backend suitable for MVPs and prototypes, but not recommended for production-critical applications before reaching version 1.0.0. Northflank serves as an infrastructure layer allowing the deployment of self-hosted Appwrite instances or custom backends with managed databases and CI/CD capabilities. The choice of an Appwrite alternative depends on factors such as database preferences, hosting models, infrastructure control, and compliance requirements, with Supabase and Firebase being the most feature-complete options for direct BaaS replacement.
