Cloudflare has introduced Basin, a data platform aimed at developers and businesses that lets them ingest, store, catalog, and query information without managing dedicated servers. The service is built on Apache Iceberg and Cloudflare R2 and is designed around an open model so that data can be used with different tools without being locked to a single provider.
Key facts about Cloudflare Basin in 20 seconds
- Basin has been publicly available since October 2, 2026.
- It uses Apache Iceberg as an open format and Cloudflare R2 for storage.
- The platform lets users ingest, catalog, and query information without managing servers.
- Cloudflare says it charges no fees for moving data between clouds, platforms, or regions.
- Anomaly and Bobsled are among the companies that have already used Basin.
Cloudflare positions Basin as an alternative to traditional data architectures that force teams to combine different services to collect, store, catalog, and analyze events. The company argues that this kind of infrastructure can require servers sized in advance, specialized teams, and costs tied to moving information between cloud providers.
The proposal builds on an idea already familiar from other parts of Cloudflare’s platform: bringing the serverless model to data work. Instead of teams having to provision and manage dedicated infrastructure for each workload, Basin runs these operations on Cloudflare’s network on demand.
The most significant difference lies in the format used to store the information. Basin stores data using Apache Iceberg, an open format that allows it to be accessed from compatible tools. According to Cloudflare, this avoids having to copy or convert data to work with different systems.
Apache Iceberg and R2 form the foundation of Basin
Cloudflare Basin combines two pieces of its architecture. On one side is Apache Iceberg, which provides the open format for organizing data. On the other, Cloudflare R2 serves as the storage layer.
The company’s goal is to separate the data from the specific tool used to analyze it. A team can store information in the open format and then use different compatible tools to run queries, without access depending on a single proprietary system.
This approach is especially relevant for applications that generate large volumes of events. Developers can send that data to Basin and later use SQL or other analytics tools to work with it.
Cloudflare also highlights the absence of data-transfer fees for queries run from different clouds, platforms, or regions. The company presents this feature as a way to cut one of the costs that can arise when an architecture combines services from multiple providers.
The platform runs on Cloudflare’s global network, according to the company, so users don’t need to provision specific servers for ingestion, storage, and query tasks. The goal is for developers to work with their data without also taking on the management of dedicated infrastructure.
From the data stack to a more open architecture
Basin is aimed especially at development teams that need to work with their own data without building a full data-engineering infrastructure. Cloudflare argues that these tasks have traditionally required combining storage, catalogs, query systems, and servers, with complexity that grows as data volumes increase.
The company says Basin lets teams concentrate those functions inside a single serverless service. Information stays stored in Apache Iceberg and can be queried using tools compatible with that standard.
Among the early use cases Cloudflare cites is Anomaly, the company behind OpenCode, an AI-based coding agent. Its co-founder, Dax Raad, says the company moved its data pipeline to Basin, replacing a setup based on Amazon S3 and Athena with the new architecture.
Bobsled, a platform specialized in data products, is also cited. The company says Basin lets it distribute data products to different regions and data and AI platforms without taking on egress fees.
These accounts are part of Cloudflare’s marketing material and are not an independent evaluation of the service. The company has presented Basin as a tool to simplify data architectures and reduce the infrastructure teams need to manage.
General availability now marks Basin’s move from early implementations to a service open to any developer or company. Cloudflare has published documentation to help users start using the platform and access its ingestion, storage, cataloging, and query features.
The move also fits a broader trend within cloud infrastructure: shifting more and more tasks that once required servers, configuration, and maintenance onto the provider. With Basin, Cloudflare applies that approach specifically to data and adds an open format as a differentiator — a strategy that mirrors how the company has expanded its developer platform more broadly, including through its push to position itself as the “AI cloud” for developers.
For teams working across multiple clouds, the ability to keep data in a format compatible with different tools can be a meaningful factor when designing an architecture. It can also simplify certain projects where developers need to analyze events generated by their applications without building a data platform from scratch.
Basin doesn’t eliminate the need to choose analytics tools, nor does it solve every need of a data architecture on its own. Its proposal focuses on reducing the infrastructure needed to ingest, store, catalog, and query information, keeping data in an open format and avoiding, according to Cloudflare, cross-cloud transfer costs.
Frequently asked questions
What is Cloudflare Basin?
Cloudflare Basin is a serverless data platform for ingesting, storing, cataloging, and querying information. It is built on Apache Iceberg and Cloudflare R2.
When did Cloudflare Basin become available?
Cloudflare announced the general availability of Basin on October 2, 2026.
What advantages does Basin offer over a traditional architecture?
Cloudflare designed Basin to avoid managing dedicated servers and reduce the need to combine different systems to handle data. The company also says queries run across different clouds, platforms, or regions carry no transfer fees.
How is Basin related to Apache Iceberg?
Apache Iceberg is the open format in which Basin stores data. This allows it to be used with compatible tools without being limited to a single provider or proprietary system.
