Neon

90/100open sourcefreemiumexplicit relation

Serverless Postgres platform separating storage and compute for branching, autoscaling, read replicas, instant restore, and scale-to-zero workloads. Neon works with standard PostgreSQL clients and ORMs, supports extensions such as pgvector, and sits inside a broader Neon backend platform with Auth, Data API, Functions, Object Storage, and AI Gateway features.

Neon provides a serverless PostgreSQL database with scale-to-zero capabilities. The Free tier includes 100 Compute Unit (CU) hours and 0.5 GB storage per month across up to 100 projects. Paid usage is consumption-based with no minimum monthly platform fee: Launch bills at $0.106/CU-hour and Scale at $0.222/CU-hour with $0.35/GB-month storage.Review →

Supabase

90/100open sourcefreemiumexplicit relation

Open-source Firebase alternative providing a full backend-as-a-service on PostgreSQL. Auto-generated REST and GraphQL APIs from your schema, real-time subscriptions, built-in auth with 20+ social providers and Row Level Security, S3-compatible file storage with CDN, and Deno-powered Edge Functions. Visual dashboard with SQL editor and table editor. Supports pgvector for AI apps. Self-hostable or managed with a generous free tier. 75K+ GitHub stars.

Supabase offers a perpetual Free tier for hobbyists and experimentation (50k MAUs, 500MB DB). The Pro tier starts at $25/month including $10 compute credits, 8GB database storage, and 250GB egress. The Team tier costs $599/month for SOC2/HIPAA compliance and priority support, alongside custom Enterprise packages.Review →

PlanetScale

82/100explicit relation

Relational database platform for MySQL and Postgres with Vitess-backed MySQL scale, PlanetScale Postgres, query insights, deploy-request workflows, and Database Traffic Control. It fits production teams that need managed relational performance, safe schema changes, replicas, and database expertise rather than a simple hobby database.

PlanetScale operates without a permanent free tier. Pricing starts at $5/month for single-node Postgres clusters and $15/month for 3-node HA Postgres, while horizontal-scaling Vitess/MySQL clusters start at $39/month. Additional storage and egress are billed on usage.Review →

UpstashUpstash provides serverless Redis, Kafka, and vector database services with per-request pricing and zero operational overhead. Redis supports global replication for edge computing. Kafka offers pay-per-message event streaming. QStash provides HTTP-based message queues for serverless. Features REST APIs alongside native protocols, ideal for edge and serverless deployments. Integrates with Vercel, Cloudflare Workers, and AWS Lambda natively.QdrantQdrant is a high-performance vector similarity search engine and database written in Rust. Designed for production-grade AI applications with advanced filtering, payload indexing, and distributed deployment. Supports billion-scale vector collections with sub-second query times. Popular choice for RAG, recommendation systems, and anomaly detection.PineconePinecone is a leading managed vector database designed for high-performance similarity search at scale. Purpose-built for AI applications including RAG, recommendation systems, and semantic search. Offers managed serverless infrastructure with automatic scaling, filtering, hybrid retrieval, and namespacing. No infrastructure management required.VectorChordVectorChord is a Postgres extension from the supervc-stack/VectorChord project that brings high-recall vector search to PostgreSQL. As the spiritual successor to pgvecto.rs, it combines IVF indexes with RaBitQ quantization to deliver Pinecone-class performance at billion-vector scale while keeping all data inside a single Postgres database — no separate vector store, no two-system sync, no rewrites when the workload grows.pgvectorpgvector is an open-source PostgreSQL extension with 22K+ GitHub stars adding vector similarity search to your existing Postgres database. Store embeddings alongside relational data, perform exact and approximate nearest neighbor search using L2, inner product, cosine, and L1 metrics. Supports HNSW and IVFFlat indexes for fast similarity queries at scale. Eliminates the need for a separate vector database by bringing vector capabilities into existing PostgreSQL infrastructure.DirectusDirectus is a database-first open data platform that wraps any existing SQL database with instant REST and GraphQL APIs, a no-code admin dashboard, and built-in authentication. Unlike traditional headless CMS platforms that impose their own data model, Directus introspects your existing schema and works on top of it — supporting PostgreSQL, MySQL, SQLite, MS SQL, MariaDB, and CockroachDB out of the box.DoltDolt is a SQL database that implements Git-style version control directly on structured data. Table changes can be staged, committed, branched, merged, diffed, and reverted through SQL workflows and a Git-like CLI. It speaks the MySQL wire protocol so existing MySQL clients, ORMs, and tools can connect with minimal driver changes. Dolt is used for AI training data management, reproducible analytics, collaborative data editing, and agent-memory experiments.WeaviateWeaviate is an open-source vector database purpose-built for AI applications. Supports vector, keyword, and hybrid search with built-in vectorization modules for OpenAI, Cohere, Hugging Face, and more. Used for RAG pipelines, semantic search, recommendation engines, and multimodal search. Written in Go for high performance.ChromaChroma is an open-source embedding database designed for simplicity and developer experience. Runs in-memory, as a Python library, or as a client-server deployment. Popular for prototyping RAG applications, local development, and lightweight vector search. Integrates natively with LangChain, LlamaIndex, and OpenAI.
