• Less suited to distributed workloads
• Pre-1.0 compatibility can change

Appwrite is a BSD-3-Clause backend platform providing databases, authentication, storage, cloud functions, messaging, hosting, realtime events, and SDKs.

Pricing: Free and self-hostable under BSD-3-Clause; hosted services may be paid.

• Complete backend platform
• Auth, databases, storage, functions, realtime, and messaging
• Mature SDK ecosystem
• More infrastructure than PocketBase
• Different database architecture
• Migration from Supabase requires application changes

Nhost is an MIT backend platform combining PostgreSQL, Hasura GraphQL, authentication, file storage, serverless functions, and realtime subscriptions.

Pricing: Open source and self-hostable under MIT; hosted plans may be paid.

• PostgreSQL
• GraphQL, auth, storage, functions, and realtime
• Local development and frontend integrations
• GraphQL-first rather than PostgREST
• Smaller community than Supabase
• Different migration workflow

Neon is an Apache-2.0-core PostgreSQL system separating compute from storage with autoscaling, scale-to-zero, database branching, extensions, and object-backed storage.

Pricing: Open-source core; managed hosted infrastructure and services may be paid.

• Real PostgreSQL
• Branching and preview environments
• Serverless compute and scale-to-zero
• Not a complete BaaS
• Auth and storage need separate services
• Hosted experience includes proprietary infrastructure

Qdrant is an Apache-2.0 vector database with similarity search, metadata filtering, hybrid retrieval, quantization, APIs, Docker deployment, and RAG integrations.

Pricing: Free and self-hostable under Apache-2.0; managed cloud may be paid.

• High-performance vector search
• Filtering, hybrid search, and quantization
• Strong RAG and AI ecosystem
• Not a full BaaS
• No application auth or file storage
• Requires other backend infrastructure

Instant is an Apache-2.0 realtime backend with a reactive database, authentication, permissions, file storage, presence, streams, offline caching, optimistic updates, and relational queries.

Pricing: Free and self-hostable under Apache-2.0; hosted services may be paid.

• Realtime by default
• Auth, permissions, storage, presence, and offline caching
• Strong multiplayer model
• Different data model from PostgreSQL
• Younger ecosystem
• Less suitable for traditional SQL-heavy apps

Bknd is an Apache-2.0 embedded backend providing database, authentication, storage, media handling, APIs, workflows, Postgres/SQLite support, and S3-compatible storage inside JavaScript frameworks.

Pricing: Free and open source under Apache-2.0; hosted services may be offered separately.

• Lightweight and framework-agnostic
• Auth, database, storage, and workflows
• Edge-compatible and embeddable
• Younger project
• Smaller ecosystem
• Pre-1.0 API changes are possible

Nitric is an Apache-2.0 cloud application framework where developers declare APIs, databases, queues, topics, secrets, and storage in code while provider plugins handle provisioning.

Pricing: Free and open source under Apache-2.0; cloud-provider costs apply.

• Multi-cloud
• Infrastructure from code
• APIs, databases, storage, queues, and local development
• Not a hosted BaaS
• Requires backend development
• No Supabase-style admin database
