Stable media URLs that survive file replacements

SteadyLink separates an asset's public identity from the revision it currently serves, which lets your application keep one address while the media behind it changes.

The problem

Because a normal storage URL points at a specific key, renaming or replacing the file can force teams to update code, content, campaigns, caches, and customer embeds.

The SteadyLink model

A SteadyLink URL points at the asset itself, so publishing a replacement creates a revision and moves that address to the new current version.

How it works

Stable delivery URL
https://cdn.steadylink.io/a/campaign-hero
  1. 1

    Create the asset

    Upload a file in the dashboard or through the API.

  2. 2

    Publish the URL

    Use the stable address in a product, site, campaign, or integration.

  3. 3

    Replace the bytes

    Upload a new revision when the media changes while every existing consumer keeps the same URL.

What this changes

Read the documentation
Replace files without editing every consumer
Keep a complete revision history behind one asset
Restore an older revision at the same address
Use a readable URL instead of exposing storage keys

Media versioning

Retain every asset replacement as a named revision, inspect metadata, restore older files, and keep the public media URL unchanged.

Private and signed media

Keep files private by default and create time-limited signed URLs when a browser, customer, or external service needs temporary access.
