Independent comparison for enterprise buyers. Updated May 2026.
Quick verdict: Choose CockroachDB when the application uses the PostgreSQL ecosystem and the team values polished multi-region managed cloud with row-level data homing for regulated workloads. Choose TiDB when MySQL compatibility matters, when hybrid transactional and analytical (HTAP) workloads on the same data are valuable, or when separated compute and storage allow independent scaling. The key differentiator is wire protocol and architecture: CockroachDB speaks PostgreSQL with integrated storage and compute; TiDB speaks MySQL with separated TiKV storage, TiFlash analytical store, and PD coordination.

CockroachDB and TiDB are both Spanner-inspired distributed SQL databases offering horizontal scale with ACID transactions, but they target different ecosystems and architect their stacks differently. CockroachDB speaks the PostgreSQL wire protocol with a subset of PostgreSQL SQL; TiDB speaks MySQL with strong MySQL 8.0 compatibility. For organisations already on PostgreSQL or MySQL, this wire-level fidelity is usually the dominant selection criterion.
Architecturally, CockroachDB integrates storage and compute in a single binary. Each node is a peer with a local KV store; SQL execution, transactions, and storage all live in the same process. This simplifies operations and deployment but couples scaling of compute and storage. TiDB separates the layers: TiDB nodes handle SQL processing, TiKV nodes handle distributed transactional storage, PD nodes coordinate metadata and placement, and TiFlash nodes hold a columnar replica synchronously updated from TiKV for analytical queries. The separation allows compute and storage to scale independently and enables true HTAP — operational and analytical queries against the same data without ETL.
The HTAP architecture is TiDB's most distinctive feature. TiFlash columnar replicas can absorb analytical query load that would otherwise contend with transactional traffic. Workloads requiring near-real-time analytics on operational data — financial dashboards, fraud monitoring, gaming telemetry — benefit materially from this architecture. CockroachDB does not currently offer a comparable columnar tier; analytical workloads typically push data to a separate warehouse via change data capture.
For multi-region deployment, CockroachDB's row-level homing for regulated data residency is more mature; CockroachDB Cloud Dedicated provides multi-region clusters with regional survival as a managed service. TiDB supports multi-region but the operational model is heavier; multi-region TiDB clusters require careful topology planning across TiKV, PD, and TiDB tiers.
For licensing, the difference matters. CockroachDB switched to a source-available licence in 2024 and removed free self-hosted Core for organisations above defined revenue thresholds. TiDB remains Apache 2.0 with no revenue-based restrictions, attractive for buyers prioritising open-source licensing. Commercial support paths differ too: Cockroach Labs is the only commercial provider for CockroachDB; PingCAP is the primary commercial provider for TiDB, with TiDB Cloud as the managed offering across AWS, Azure, and Google Cloud.
CockroachDB Cloud Serverless is free up to defined request units; production Dedicated tiers price per vCPU, request unit, and storage, typically $3,000–$25,000 per month for production clusters. Self-managed CockroachDB Enterprise prices per vCPU per year, typically $1,000–$2,500 per vCPU annually. TiDB Cloud prices by request units and storage with Serverless and Dedicated tiers; Dedicated clusters typically run $2,500–$22,000 per month depending on TiDB, TiKV, and optional TiFlash node count. Self-managed TiDB Open Source is free under Apache 2.0; PingCAP provides commercial support typically priced $5,000–$20,000 per node per year depending on tier.
Five-year cost of ownership for a moderate distributed SQL workload: CockroachDB Cloud Dedicated $1.5M–$4M; CockroachDB self-managed Enterprise $1M–$3M plus staffing; TiDB Cloud $1.2M–$3.5M (higher when TiFlash analytical replicas are sized for heavy reporting); TiDB self-managed $500K–$2M depending on commercial support and HTAP scope. The primary buying-side caveat for CockroachDB is the 2024 licence change and removal of free self-hosted Core for larger organisations. For TiDB, the caveat is operational complexity from the multi-tier architecture: TiKV, PD, and TiDB nodes require coordinated capacity planning and upgrade orchestration that many teams underestimate at first. Pricing as of May 2026.
Choose CockroachDB when the application stack already centres on PostgreSQL, when row-level data homing for regulated geographies is a hard requirement, when a polished managed-cloud experience matters more than open-source licensing, when multi-region survival with automatic regional failover is critical, or when operational simplicity from an integrated single-binary architecture is valued. CockroachDB suits global SaaS with regional data residency, financial services requiring multi-region OLTP, and applications inheriting PostgreSQL clients, drivers, and ORMs that should continue to work without rewrites.
Choose TiDB when MySQL wire compatibility matters for existing applications, when hybrid transactional and analytical workloads on the same data justify TiFlash columnar replicas, when Apache 2.0 licensing avoids commercial lock-in, when separated compute and storage allow independent scaling, or when the workload involves heavy reporting alongside operational traffic that would otherwise need a separate warehouse. TiDB suits e-commerce, gaming, ad-tech, and financial services with HTAP requirements, and any MySQL-heavy stack outgrowing single-node MySQL or Aurora.
