A serverless document database for modern applications

Fauna is a developer-friendly, transactional document database delivered to you as a secure, cloud API with native GraphQL, that integrates easily with your preferred development stack.

Modern applications need a modern database

NoSQL databases, synonymous with document databases, offer development flexibility and scale, often at the expense of transactional correctness (ACID properties) and operational simplicity.

Delivered as a cloud API, Fauna is a modern document-centric data layer that supports document, key-value and graph-styled querying, combined with serializable transactions, relations, advanced indexing and the ability to execute business logic close to data. Additionally, Fauna offers innovative capabilities such as data temporality, streaming, and multi-tenancy, and built-in support for GraphQL.

If you like document databases, especially their flexibility and scale, 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 flexibility of the NoSQL model with the transactional properties of an RDBMS resulting in a database that fits better with modern application development. Moreover, its serverless approach completely eliminates the provisioning, planning and administrative tasks routine with traditional document database services.

A flexible data model

Fauna is an indexed document database that enables you to represent a variety of business data with ease. Document data, relational data, key value pairs and even graph data - Fauna has it covered.

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 NoSQL queries with business logic

Write document queries, relational queries (including joins), graph traversals, basic search or a combination using FQL or GraphQL . Fauna also lets you create UDFs that encapsulate powerful business logic easily accessible from code via an API call.

Handsfree HA & global replication

Fauna automatically distributes your 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, 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 legacy NoSQL cloud services. Fauna scales transparently and takes care of all the data operations.

What's the buzz about?

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

Fauna combines the scalability of MongoDB or DynamoDB with the reliability and power of SQL databases. Whether you’re using it only as a data store in your backend or if it is the entire backend of your app, Fauna is a real game-changer.

Felix Engelhardt, Lead Engineer at EIDU

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.
