pgvector
Free
pgvector is an open-source PostgreSQL extension for vector similarity search, allowing developers to store and query vector embeddings directly in their existing PostgreSQL database. It supports exact and approximate nearest neighbor search with HNSW and IVFFlat indexing methods for production AI applications. Backend developers use pgvector to add AI-powered semantic search to their applications without adopting a separate vector database.
🤖
PostgreSQL
Free
PostgreSQL is the world's most advanced open-source relational database with 35+ years of active development. It supports complex queries, foreign keys, triggers, views, transactional integrity, and MVCC concurrency. PostgreSQL's extensibility enables custom data types, functions, and extensions including pgvector for AI vector search. With JSON support, full-text search, and PostGIS for geospatial data, PostgreSQL handles virtually any data workload. Used by startups and enterprises including Apple, Instagram, and Reddit as their primary production database for mission-critical applications.
🤖
MongoDB
Freemium
MongoDB is the world's most popular NoSQL database storing data as flexible JSON-like documents rather than rigid rows and columns. Its schema-less design enables rapid iteration without migrations. MongoDB Atlas provides a fully managed cloud version across AWS, Azure, and GCP. Atlas Vector Search adds AI-powered semantic search to MongoDB collections. Used by over 46000 customers including Toyota, Verizon, and Forbes for applications requiring flexible data models, horizontal scalability, and real-time analytics across diverse document structures.
🤖
Redis
Freemium
Redis is an open-source in-memory data structure store used as a database, cache, and message broker. It supports strings, hashes, lists, sets, sorted sets, and streams with operations atomic by default. Redis's sub-millisecond response times make it the standard for caching, session management, real-time leaderboards, and pub/sub messaging. Redis Stack adds vector similarity search, JSON, time series, and graph capabilities. Used by Twitter, GitHub, and Stack Overflow for caching and real-time data processing at massive scale.
🤖
MySQL
Freemium
MySQL is the world's most widely deployed open-source relational database powering millions of web applications globally. Its combination of performance, reliability, and ease of use made it the default choice for LAMP stack applications. MySQL 8.0 added window functions, CTEs, and JSON document storage alongside traditional relational features. Cloud-managed options include Amazon RDS, Google Cloud SQL, and Azure Database for MySQL. Used by WordPress, YouTube, and Facebook as a foundational data store for high-traffic web applications.
🤖
Supabase
Freemium
Supabase is an open-source Firebase alternative providing a PostgreSQL database, authentication, instant APIs, edge functions, realtime subscriptions, and storage in one platform. Its auto-generated REST and GraphQL APIs eliminate backend boilerplate. Supabase pgvector integration enables AI vector search directly in the database. Used by 500000+ projects as a backend-as-a-service for building full-stack applications rapidly without managing separate infrastructure for database, auth, storage, and APIs — popular with indie developers and startups.
🤖
PlanetScale
Freemium
PlanetScale is a MySQL-compatible serverless database platform built on Vitess, the database clustering system that powers YouTube. Its non-blocking schema changes eliminate downtime during database migrations. Branching enables safe database schema development like code branches. PlanetScale's automatic sharding scales horizontally without application changes. Used by teams at Airbyte, Hashnode, and Netlify for building applications that need MySQL compatibility with horizontal scale, zero-downtime schema changes, and serverless deployment model.
🤖
CockroachDB
Freemium
CockroachDB is a cloud-native distributed SQL database designed for global applications requiring high availability and strong consistency. It automatically replicates data across regions and survives hardware failures with zero downtime. CockroachDB is PostgreSQL-compatible enabling easy migration. Its geo-partitioning feature keeps data in specific regions for compliance. Used by enterprises including Comcast, Lush, and DoorDash for applications requiring globally distributed databases that maintain SQL semantics and ACID guarantees at planetary scale without operational complexity.
🤖
Apache Cassandra
Free
Apache Cassandra is a highly scalable, distributed NoSQL database designed for handling massive amounts of data across many commodity servers with no single point of failure. Its masterless architecture delivers linear scalability and proven fault-tolerance. Cassandra excels at write-heavy workloads and time-series data. Used by Apple (storing 10+ petabytes), Netflix, and Instagram for storing massive datasets requiring high write throughput, geographic distribution, and 99.999% uptime guarantees that relational databases cannot match at extreme scale.
🤖
ClickHouse
Freemium
ClickHouse is an open-source column-oriented analytical database designed for real-time analytics on large datasets. It processes billions of rows per second making it the fastest analytical database available. ClickHouse Cloud provides a managed version. Used by Cloudflare processing 12 trillion queries daily, Uber, and ByteDance for real-time analytics on event data, logs, and metrics where query performance on large datasets is critical. ClickHouse achieves query speeds 100x faster than traditional row-oriented databases on analytical workloads.
🤖
Neon
Freemium
Neon is a serverless PostgreSQL database with a branching feature that enables creating isolated database copies instantly for development and testing. Its separation of storage and compute enables scaling to zero when inactive for cost efficiency. Neon's instant branching lets developers create database branches like code branches for feature development. Used by developers and teams wanting fully managed PostgreSQL with serverless economics, instant provisioning, and database branching capabilities that eliminate the operational overhead of traditional database management.
🤖
Turso
Freemium
Turso is an edge-optimised database built on libSQL, a fork of SQLite, designed for applications needing ultra-low latency data access globally. It replicates databases to 30+ edge locations worldwide with sub-10ms response times for users anywhere. Turso's embedded replicas enable SQLite-compatible databases that sync from the edge. Used by developers building globally distributed applications, edge computing workloads, and serverless applications where database latency is a critical performance bottleneck for user experience.
