Websites & Apps

Ar.io lets teams and individuals publish static sites and web application builds permanently, serve them from independent gateway caches, and give them readable ArNS names. Every deployment keeps its own permanent address, so earlier versions stay reachable.

This makes ar.io well suited for applications and sites that must remain available over the long term, including public-facing platforms, educational resources, documentation, digital products, and archival or legacy projects.

Why web deployments disappear

Most websites do not disappear because they are no longer needed. They disappear because hosting expires, infrastructure changes, providers shut down, or links break.

Ar.io addresses these structural risks by separating site access from traditional hosting dependencies.

What permanent deployment changes

Durable deployment addresses

Each build published through ar.io receives a permanent transaction address that remains stable through server changes, migrations, or expired hosting.

Up-front permanent storage

ar.io uses Arweave's up-front storage model, so the permanent deployment record does not depend on a conventional recurring hosting subscription. ArNS leases and application operations remain separate concerns.

Resilient access without single points of failure

Independent ar.io gateways can cache and serve each build, giving applications more than one retrieval path during outages and service disruptions.

Version preservation and historical continuity

Each deployment version has its own immutable transaction ID. Teams can reference, audit, or restore an earlier build without overwriting its history.

Discoverable, human-readable access

ArNS gives a site a readable name that can point to its current permanent deployment while earlier versions remain directly addressable.

Who this is for

• User platforms publishing content on behalf of users
• Teams shipping long-lived documentation or digital products
• Educational and research organizations
• Public-facing services requiring durable access
• Builders seeking to reduce hosting risk and maintenance overhead

Why durable deployments matter

The web was not designed for permanence. As more value moves online, broken links, inaccessible applications, and lost references quietly erode trust, usability, and institutional memory.

Once published through ar.io, a deployment remains addressable through its transaction ID and compatible gateways.

Publish a permanent site or application

Upload through the ar.io Console or follow the developer documentation, then register a programmable ArNS smart domain for a stable application name.
