The ar.io Network
The cloud that outlives its provider.
ar.io is an open network of independent gateways that cache, index, verify, and serve your data at web speed. Nothing expires, and no single operator can take it offline.

Why ar.io exists
Storage is the foundation, not the finished experience.
Data can be stored forever and still be slow to reach, hard to find, impossible to verify, and reliant on one company's server staying up. Permanence at the storage layer does not, by itself, give you any of that.
ar.io is the network that closes the gap. Independent gateways cache, serve, index, and verify permanent data under a shared protocol, and ArNS gives records and applications names that outlast the infrastructure serving them.

Six things you can do in the next ten minutes.
The ar.io Console is the fastest way in. Connect a wallet or an email address, and every one of these is self-service.
Deploy
Publish a static site or app with manifests handled for you, then point a domain at it.
Pages
Build a link-in-bio page from a template and publish it permanently. No code, no files.
Capture
Archive any public webpage as a full-page screenshot you can cite and prove later.
Browse
Open permaweb content by name or ID, with cryptographic verification as you read it.
Domains
Search, register, and manage ArNS names, including undernames for sub-paths.

Apps and people
No single point of failure
Independent operators run gateways under a shared protocol. Applications route across many of them instead of depending on one provider staying online, funded, or friendly.
Verifiable, not trusted
Every response can be checked against its cryptographic record, and you can see which gateway served it. Correctness does not rest on anyone's promise.
Findable, not just stored
Gateways index content so it can be queried by metadata and reached by a readable name, rather than only by a raw transaction ID.
In production
Archives that have to outlive their institutions.
The clearest test of permanent infrastructure is whether a collection survives the organization that published it.
Public knowledgeProject Gutenberg, preserved
The archive is served through gutenberg.ar.io with no recurring storage bill and no host that can quietly take it down.
