CrateDB

Overview

CrateDB is a database for real-time analytics on live operational data. It suits teams that need to query varied data through SQL while scaling across nodes; its main trade-off is that the managed-service costs can rise beyond a modest free allocation, and larger tiers require custom pricing.

Its open-source core is licensed under Apache 2.0, and CrateDB can run on-premises, at the edge, in the cloud, or as a managed service. The company was founded in 2013 and is headquartered in Redwood City, California.

Its range spans Distributed SQL Databases, OLAP Databases, Columnar Databases, Spatial Databases, and Multimodel Databases, as well as the broader Database Software category.

Key features

One engine for varied data

CrateDB supports time-series, JSON, full-text, vector, geospatial, and structured data in one engine. That breadth can reduce the need to split operational analytics across separate systems. SQL includes joins, aggregations, and window functions, and is designed to work across billions of rows without pre-aggregation or schema redesign. This makes it a compelling fit for mixed workloads, though the stated breadth alone does not tell teams how their own queries will perform.

Scale and connectivity

Built-in replication and automatic failover are intended to support availability, while automatic sharding and horizontal scale-out let deployments grow by adding nodes. PostgreSQL wire protocol support and a native HTTP endpoint give applications more than one route to connect. Integrations include Tableau, Power BI, Grafana, Apache Kafka, Apache Spark, and dbt, which makes CrateDB more practical in established analytics and data pipelines.

Security and support

CrateDB supports authentication, role-based access control, TLS/SSL connections, encrypted storage volumes, and audit logging in CrateDB Cloud. Cloud defaults include encryption at rest, IP allowlists, MFA, and isolated clusters; CrateDB Cloud also holds ISO 27001 and SOC 2 Type II certifications. The security and compliance provisions are useful for organizations with formal controls, while audit logging is specifically described for Cloud.

Support options include a developer community, GitHub, documentation, official support plans, and ticket support. Dedicated includes basic support, and premium support is available. That gives teams routes beyond self-service, though only some support is bundled with a stated tier.

Pricing

CrateDB uses a freemium model. Its free options make evaluation possible without a paid commitment, but limited compute and storage make them a starting point rather than an obvious fit for sustained, larger workloads.

CrateDB Cloud’s Free Plan costs nothing and provides 2 vCPUs, 2 GB RAM, 8 GB storage, and backups once per day; no credit card is required. It is best for lightweight evaluation, not workloads that outgrow those caps.

Cloud Shared costs $0.07 a month, billed Hourly, as displayed. It provides a single-node shared environment with up to 8 shared vCPUs, 12 GB RAM, and 1 TB storage, plus development support. The shared single-node setup is a fit for development or smaller needs, but it lacks the multi-node capacity and uptime SLAs of Dedicated.

Cloud Dedicated costs $0.25 a month, billed Hourly, as displayed. It includes basic support, up to 9 nodes, 144 vCPUs, 495 GB RAM, and 72 TB storage, as well as uptime SLAs, AWS/Azure Private Link, and backups once per hour. It is the more capable managed tier for production requirements, but its listed hourly billing basis and lack of a total projected cost make budgeting important.

Cloud Custom has custom pricing and offers a dedicated environment, unlimited nodes and storage, custom compute, premium support, uptime SLAs, AWS/Azure Private Link, custom backups, and dedicated master nodes. It targets deployments beyond Dedicated’s stated limits; teams should seek a quote before committing.

Platforms

CrateDB supports API, Linux, macOS, self-hosted, web, and Windows use. Linux and macOS installation information is provided, along with Docker and Kubernetes guides. The combination of managed and self-hosted deployment gives infrastructure teams flexibility, while the range of deployment choices means setup and operations will depend on which route they select.

Who it's for

CrateDB is best suited to teams analyzing live operational data across several data types, especially when they want SQL, PostgreSQL compatibility, multiple connectivity routes, and horizontal scaling. Its integrations and managed-service security features also suit organizations connecting analytics tools and pipelines or working under formal security requirements.

It is a weaker fit for buyers who need a published total cost for Shared, Dedicated, or Custom, or whose workloads exceed the free plan but do not justify custom-priced tiers. The free plan’s 8 GB storage and 2 vCPUs are also restrictive for substantial ongoing use.

Pros and cons

• Pros: Six data types in one engine can simplify mixed-data analytics without schema redesign or pre-aggregation.
• Pros: Automatic sharding, replication, failover, and node-based scale-out support growth and availability needs.
• Pros: PostgreSQL wire protocol, HTTP, and integrations with tools such as Tableau, Grafana, Kafka, and dbt offer useful connectivity options.
• Pros: Cloud security defaults, ISO 27001 and SOC 2 Type II certifications, and Private Link on higher tiers address enterprise deployment concerns.
• Cons: The free Cloud allocation is capped at 2 vCPUs, 2 GB RAM, and 8 GB storage, limiting its usefulness beyond evaluation or small workloads.
• Cons: Cloud Shared is a single-node shared environment, while uptime SLAs and hourly backups appear with Dedicated rather than Shared.
• Cons: Shared, Dedicated, and Custom lack published prices, making cost comparison and budget planning harder.

Alternatives

Choose MySQL instead if you want a freemium database with a free trial and Community Edition, or OceanBase Database if its free Community Edition or Enterprise option better matches your needs. TBase is another free database option.

VoltDB is worth considering if you want a free Developer Edition for individual developers and early exploration, with sample apps, tutorials, and documentation. CockroachDB Cloud offers a Standard plan priced at $0.06 a month, billed by cloud usage monthly and metered by the minute, with rates shown for AWS us-east-1 and varying by region. For a free cloud starting point with per-organization quotas, TiDB Cloud Starter provides 25 GiB row storage, 25 GiB column storage, and 250M R.

PrestoDB is a free, self-hosted SQL query engine, while SingleStore Helios has a free Shared workspace for evaluation, development, and non-production testing.

Verdict

Choose CrateDB for live operational analytics when your data spans several types and you want SQL, connectivity flexibility, and a path to scale across nodes. Its breadth and deployment choice are real advantages; look elsewhere if the free caps are too small or if you need predictable published pricing before selecting a larger managed tier.
