What is Sia?

A storage marketplace enabling buyers to rent space from sellers with extra disk space

Made for Developers

Sia was made to be integrated as your storage backend. You only pay for the storage you use, and there is no commitment. Get started with our API Quickstart Guide.


Sia is a decentralized network consisting of many nodes around the world. Data is stored redundantly on a diverse subset of these nodes, meaning there’s no single or central point of failure.

Competitively Priced

Sia is a storage marketplace. The price of storage on the network is determined by the free market equilibrium, often well below the price of centralized storage. Compare Sia to other storage solutions.
