Sia review
A broad, encrypted storage platform with a free tier and flexible access options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sia is a decentralized storage service for individuals, teams, developers, storage renters, and storage providers. It distributes encrypted, erasure-coded data across independent hosts and uses blockchain-enforced storage contracts. The Sia Storage app focuses on personal cloud storage, while SDKs, an S3-compatible gateway, and self-hosted software extend the platform for technical and operational use cases. Its deployment options cover cloud, self-hosted, desktop, and mobile environments.
The subscription plans provide a clear entry point. Free includes 50 GB of storage, 3 apps, and 500 Mbps speed. Plus increases storage to 500 GB while retaining 3 apps and 500 Mbps speed. Pro provides 5 TB, 5 apps, and 1 Gbps speed. Unlimited provides 10 TB, 100 apps, and 5 Gbps speed. Beyond these plans, the open storage network uses provider-set Siacoin pricing rather than a fixed vendor subscription. That gives the network a different buying model from the Sia Storage app.
Sia stands out for its combination of client-side encryption before upload, redundant distribution, storage contracts, synchronization, versioning, and automatic photo backup. Its ecosystem includes S3-compatible clients, rclone, Cyberduck, Nextcloud, Duplicati, IPFS gateways, and SDKs for Rust, Go, Python, and JavaScript. Broad Windows, macOS, Linux, iOS, and Android coverage suits users with varied device fleets. Choose Sia if encryption, decentralized distribution, and broad platform access matter. Consider another option if you want a single conventional subscription model or minimal setup choices.
