A serverless relational database for modern applications

Validated by Jepsen, Fauna is a flexible, developer-friendly, relational database delivered to you as a secure, Global API with native GraphQL, that integrates easily with your preferred development stack.

Modern applications need a modern database

RDBMS systems designed in the 1970s did not scale. To solve this problem, NoSQL databases sacrificed correctness and flexibility, while NewSQL databases and cloud services sacrificed operational simplicity and performance. Productivity suffered.

Delivered as a Global API, Fauna is a modern relational data layer that supports relational querying, serializable transactions, database normalization, foreign keys, indexes, constraints, stored procedures, and other typical relational features. Additionally, Fauna offers innovative capabilities such as data temporality, streaming, and multi-tenancy, combined with schema flexibility and built-in support for GraphQL.

If you like relational databases, especially their transactional properties and battle-hardened reliability, but wish to minimize your operational burden, gain flexibility, and free yourself from routine tasks such as data partitioning, replication, redundancy, etc. you may enjoy Fauna even more!

Simplify code, reduce costs, and ship faster

Fauna combines the operational integrity and relational modeling of RDBMS with a flexible interface and architecture that fits better with modern application development. Moreover, its serverless approach completely eliminates the provisioning, planning and administrative tasks routine with traditional relational database services.

Relational yet flexible

Fauna supports database normalization, foreign keys, indexes, constraints, stored procedures, and other typical relational database features yet is schema flexible, enabling a simpler agile workflow.

100% ACID

Built on a ground-greaking distributed data and compute engine, Fauna is a transactional database with strictly serializable transaction isolation. With Fauna, all your reads and writes are transactional, yet fast.

Powerful queries with business logic

Write relational queries (including joins), or combine with document queries, graph traversals, or basic search! Similar to stored procedures, Fauna lets you create UDFs that encapsulate powerful business logic easily accessible from code via an API call.

Handsfree HA & global replication

Fauna automatically distributes data to multi-region locations. As a result, it delivers predictable low latency read/write access no matter where your clients are running, as well as protection against data loss from infrastructure failures.

Secure by default

With built-in authorization and a fine-grained security framework that integrates easily with 3rd party authentication services such as Auth0, Fauna makes it simple to implement your data security rules.

Zero operations at any scale

Say goodbye to data sharding, capacity provisioning, and database administration tasks typically associated with traditional databases and cloud services (DBaaS). Fauna scales transparently and takes care of all the data operations for you.

What's the buzz about?

Our customers love Fauna because it is productive, modern, uncompromising and operations-free.

Fauna is the data API of choice for our applications. The rich, versatile feature set helps us build business logic faster. It performs and auto scales irrespective of the load or size of data. It eliminates our database maintenance and operations overheads, thereby speeding up development while reducing costs. Furthermore, it is backed by an awesome user community and customer support that we love.

Our testing suggests that Fauna offers serializability, and, optionally, strict serializability, in only one cross-datacenter round-trip ... Calvin-based systems like Fauna could play an important future role in the distributed database landscape.
