Supabase

Supabase

Supabase is an open source Postgres development platform providing authentication, auto-generated REST/GraphQL APIs, realtime subscriptions, edge functions, file storage, and vector embeddings.

Supabase is an open source Postgres development platform for building web, mobile, and AI applications. It combines PostgreSQL with a set of services for authentication, instant APIs, realtime updates, serverless functions, and file storage.

Key Features

  • Dedicated PostgreSQL database with SQL, roles, and Row Level Security
  • Auto-generated REST APIs from your database schema
  • Optional GraphQL API via a PostgreSQL extension
  • Authentication and authorization with JWT-based sessions and OAuth2 support
  • Realtime subscriptions over WebSockets driven by PostgreSQL changes
  • File storage service with access control policies backed by Postgres
  • Edge/serverless functions for custom backend logic
  • Vector/embeddings support using Postgres extensions (for semantic search and RAG patterns)
  • Web-based dashboard for managing projects, data, and configuration

Use Cases

  • Replace or self-host a Firebase-like backend for apps with Postgres
  • Build internal tools and SaaS backends with auth, APIs, and storage
  • Create AI-enabled applications using Postgres vector search and embeddings

Limitations and Considerations

  • Some functionality relies on multiple cooperating components (database, realtime, auth, storage, gateway), which increases operational complexity compared to a single service
  • Feature set and behavior can vary depending on the chosen self-hosting setup and enabled extensions

Supabase provides a cohesive backend stack around PostgreSQL while keeping data ownership and portability. It is well-suited for teams that want a modern developer experience with SQL and strong database-native security controls.

Coolify is an open-source, self-hostable platform-as-a-service that helps you deploy and manage applications, databases, and Docker-based services on your own infrastructure via SSH. It aims to provide a Heroku/Vercel/Netlify-style experience without vendor lock-in.

Key Features

  • Deploy static sites, APIs, and full-stack apps across many languages and frameworks
  • Git-based “push to deploy” workflows with support for popular Git providers
  • One-click deployment catalog for a large set of Docker-compatible services
  • Automatic TLS certificate provisioning and renewal for custom domains
  • Built-in database provisioning and automated backups to S3-compatible storage
  • Webhooks and a REST API for automation and CI/CD integrations
  • Real-time in-browser terminal for server and deployment management
  • Team collaboration with roles/permissions and shared projects
  • Pull request / preview deployments to review changes before merging
  • Basic monitoring and notifications for deployments and server resources

Use Cases

  • Replace managed PaaS products for hosting web apps on VPS or bare metal
  • Run an internal deployment platform for teams with previews and role-based access
  • Deploy and manage databases and common infra services alongside applications

Limitations and Considerations

  • Requires Docker-based deployments; services generally need to be containerized
  • Feature set and operational complexity can increase when managing many servers

Coolify is a strong fit for developers and teams who want an easy, Git-driven deployment workflow while keeping full control over infrastructure, data, and configurations. It scales from a single server to multi-server setups and supports both apps and supporting services in one place.

bknd

bknd

bknd is a lightweight Firebase/Supabase alternative that provides a modular backend with REST API, admin UI, auth, media, and workflows, deployable across many JS runtimes.

bknd is a lightweight backend platform that provides core primitives most applications need, including data management, authentication, media handling, and workflows. It is designed to run in many JavaScript runtimes and can be deployed standalone or embedded into popular web frameworks via adapters.

Key Features

  • Modular, opt-in building blocks for data, auth, media, and workflow automation
  • Integrated admin UI for managing schema, data, and backend configuration
  • Instant REST API with OpenAPI support and a type-safe TypeScript SDK
  • Adapter-first architecture for multiple runtimes and infrastructure providers
  • Supports SQL backends including SQLite variants and PostgreSQL
  • Storage adapters for S3/S3-compatible providers and filesystem-based storage

Use Cases

  • Build MVPs and prototypes with a ready-to-use backend and admin panel
  • Create API-first apps that need a portable, framework-agnostic backend
  • Run SaaS backends with user management and multi-tenant data isolation patterns

Limitations and Considerations

  • Requires Node.js 22.13+ for certain Node-based deployments
  • Actively developed project; backward compatibility may change before 1.0

bknd is a practical choice when you want a compact backend that can be deployed across environments without committing to a single vendor. Its adapter-based approach makes it suitable for teams that want control over databases, storage, and runtime choices while keeping development simple.

Para

Para

Para is an open-source, Java-based multitenant backend framework providing a RESTful JSON API, full-text search, distributed caching, and flexible authentication for web, mobile, IoT and prototype apps.

Para screenshot

Para is a modular, Java-based backend framework that provides object persistence, search indexing and distributed caching for web, mobile and IoT applications. It exposes a RESTful JSON API and is designed for multitenant deployments and rapid prototyping.

Key Features

  • Multitenancy: each application has its own storage, search index and cache isolation.
  • RESTful JSON API with signed requests and stateless client authentication using JSON Web Tokens (JWT).
  • Database-agnostic persistence layer with adapters for various data stores and lightweight support for embedded databases.
  • Full-text search support via Lucene or Elasticsearch with automatic indexing of objects.
  • Distributed and local caching options (Hazelcast or other cache implementations) for low-latency access.
  • Pluggable security: LDAP/SAML/social login support, CSRF protections and resource-level permissions.
  • Validation and robustness via JSR-303 / Hibernate Validator and optimistic locking support in DAOs.
  • Modular architecture with dependency injection and plugin support, executable JAR with embedded servlet container, and metrics/monitoring integration.

Use Cases

  • Rapidly build backend APIs for mobile and single-page web applications with per-app multitenancy.
  • Add full-text search and indexing to application data using Lucene or Elasticsearch.
  • Provide a unified backend for IoT or game clients that need scalable caching and flexible auth.

Limitations and Considerations

  • JVM-centric: primarily a Java/Maven codebase and requires a Java runtime to run and build.
  • Relies on external components for some functionality: search (Elasticsearch/Lucene) and distributed cache (Hazelcast) need to be provisioned and configured for production scaling.
  • Advanced integrations and hardening (e.g., enterprise SSO, specific DB backends) require additional setup and testing per deployment.

Para is targeted at teams that want a tested, extensible backend framework rather than a managed SaaS API. It is suitable for prototyping and production deployments where a JVM-first, modular backend with search and caching is desirable.
