TiDB is an open-source, MySQL-compatible distributed SQL database built for elastic horizontal scale, high availability, and HTAP (Hybrid Transactional and Analytical Processing). Developed by PingCAP, it unifies OLTP, real-time analytics, and native vector search in a single engine—replacing separate transactional databases, data warehouses, and vector stores. TiDB Cloud offers fully managed serverless and dedicated tiers on AWS, GCP, and Azure, while TiDB Self-Managed runs on Kubernetes or bare metal. As of 2025–2026, PingCAP positions TiDB as the primary database for agentic AI workloads, emphasizing ACID consistency, multi-tenant isolation, autoscaling to zero, and MCP-based AI agent connectivity.

CockroachDB is a distributed SQL database that stores data across a symmetric cluster of nodes, automatically replicating and rebalancing data to survive node and regional failures without operator intervention. It speaks the PostgreSQL wire protocol, enabling compatibility with existing PostgreSQL drivers, frameworks, and tooling. The product spans three deployment modes—CockroachDB Cloud (fully managed, multi-tenant), Bring Your Own Cloud (managed control plane, customer VPC), and Self-Hosted Enterprise—and includes built-in features for multi-region data placement, change data capture, native vector search (C-SPANN), and AI agent tooling (MCP Server, Agent Skills).

ClickHouse is a high-performance, open-source column-oriented OLAP database for real-time SQL analytics on large-scale datasets, offered as a self-managed open-source distribution or as a fully managed cloud service (ClickHouse Cloud) on AWS, GCP, and Azure, with additional products including ClickStack (open-source observability), chDB (in-process SQL engine), and Langfuse (LLM observability, acquired January 2026).

Supabase is the open-source Postgres development platform that bundles a dedicated hosted PostgreSQL database, authentication, auto-generated REST and GraphQL APIs, realtime subscriptions, file storage, serverless edge functions, and vector embeddings into a single integrated backend platform. It is built on open-source components (PostgreSQL, PostgREST, GoTrue, Elixir Realtime) and supports both managed cloud and self-hosted deployments, making it a full-featured, lock-in-free Firebase alternative for modern web, mobile, and AI applications.

Neon is an open-source, developer-first serverless Postgres platform that re-architects PostgreSQL with a distributed, multi-tenant storage layer decoupled from compute. Its signature capabilities—instant database branching, automatic scale-to-zero, vertical autoscaling, and a REST/CLI API for fleet management—make it well-suited for modern application development workflows, AI agent backends, and developer platforms embedding Postgres for their users. Now a Databricks company, Neon's core technology also powers Databricks Lakebase.

QuestDB is a high-performance, open-source time-series database delivering SIMD-accelerated SQL, ingestion throughput up to 8 million rows per second, multi-tier storage with native Apache Parquet support, and time-series SQL extensions (ASOF JOIN, SAMPLE BY, streaming materialized views). Targeting capital markets, IoT telemetry, and real-time analytics, it is available as Apache 2.0 open source or as QuestDB Enterprise (self-managed or BYOC) for production-grade HA, security, and scale.

MongoDB Atlas is a fully managed, multi-cloud developer data platform that unifies operational, vector, search, time-series, and streaming data workloads within a single developer experience. The core MongoDB database engine uses a flexible document model (BSON/JSON) enabling agile schema design and horizontal scalability through automatic sharding. Atlas layers managed infrastructure automation, integrated Atlas Vector Search for AI and RAG applications, Atlas Search (Lucene-based full-text), Atlas Stream Processing (Kafka-native), Queryable Encryption, Atlas Charts, and a rich integration ecosystem on top of the database engine. Self-managed options (Community Edition and Enterprise Advanced) are available for on-premises or private cloud deployments.

PlanetScale provides fully managed Vitess/MySQL and PostgreSQL databases optimized for high-throughput OLTP workloads. Its differentiating features are NVMe Metal performance (unlimited IOPS), Git-style database branching with zero-downtime schema changes, built-in horizontal sharding via Vitess, 100%-capture query Insights, and enterprise-grade compliance (SOC 2 Type 2, PCI DSS 4.0, HIPAA). A next-generation Postgres sharding architecture (Neki) is in development.

SingleStore Helios is a distributed, cloud-native SQL database that unifies transactional and analytical processing in a single engine with native multi-model support spanning relational, JSON, vector, full-text, time-series, and geospatial data. It is designed for enterprise AI and real-time application workloads requiring ultra-low latency and high concurrency at petabyte scale.

Redis is a real-time in-memory data platform offering a multi-model database—key-value, document (JSON), time series, vector, and probabilistic data structures—with native support for caching, pub/sub messaging, streams, full-text search, vector similarity search, and AI agent memory. Available as open source, self-managed enterprise software, or a fully managed cloud service, Redis delivers sub-millisecond latency at scale and serves use cases from application caching to GenAI-powered RAG pipelines. Its expanding AI product suite includes LangCache (fully managed semantic caching for LLMs), Redis Data Integration (CDC-based real-time sync), and integrations with major AI agent frameworks including LangChain, LangGraph, and AutoGen.

Xata is a modern PostgreSQL platform that gives every developer, CI job, or AI agent its own isolated Postgres branch with real (anonymized) production data in seconds, powered by copy-on-write storage separation. It runs 100% upstream Postgres, is open source under Apache 2.0, and can be deployed as a managed cloud service or in a customer's own cloud account.

Timescale (Tiger Data) provides a PostgreSQL-native time-series database platform: the open-source TimescaleDB extension, the fully managed Tiger Cloud (available on AWS and Azure Marketplaces), and TimescaleDB Enterprise for on-premises and private cloud deployments. Key technical primitives include Hypertables for automatic partitioning, Hypercore for hybrid row/columnar storage, columnar compression up to 95%, tiered storage to object storage, continuous aggregates for real-time materialized views, 200+ time-series SQL hyperfunctions, vector search via pgvectorscale and pg_textsearch, and TigerLake for native Apache Iceberg lakehouse integration.

EdgeDB/Gel was a graph-relational database and managed cloud platform built on PostgreSQL. It offered a high-level object-type data model (replacing tables and JOINs with object types and links), its own composable query language (EdgeQL), full SQL support, declarative schema migrations, built-in authentication, AI/vector database extensions, a TypeScript query builder with code generation, and multi-language client libraries. A managed cloud service (Gel Cloud) was available with Vercel and GitHub integrations. The commercial entity shut down in December 2025; the software remains open source.

Fauna was a serverless, globally distributed database delivered as a web-native cloud API, combining document model flexibility with relational querying and strong ACID consistency. Its zero-operations model—eliminating provisioning, sharding, replication management, and cluster administration—made it a favored choice for serverless and edge-compute application stacks. The service was shut down on May 30, 2025, with core technology committed to open-source release.

Turso is a SQLite-compatible database platform comprising libSQL (a production-ready open-contribution SQLite fork), Turso Database (a Rust-rewritten SQLite engine in beta), and Turso Cloud (a fully managed serverless DBaaS). It is designed to provision millions to billions of lightweight, isolated SQLite databases — one per user, tenant, agent, or session — with built-in vector search, embedded replicas for local reads, copy-on-write branching, and global distribution, making it purpose-built for AI agents, multi-tenant SaaS, local-first mobile, and edge workloads.
