Stop babysitting your database and build for the future

While Postgres is easy to get started with, it can quickly become a source of pain for developer teams. Many applications built initially on Postgres hit scaling limits, and SQL’s connection model doesn’t fit with serverless architectures.

Fauna manages all database operations for you, ensuring scalability, durability, and high availability. You and your team can focus on building your app’s differentiated features and services instead.
