Origin Trials

Origin Trials enable developers to use an experimental feature in production and provide essential feedback.

The AMP Origin Trial process is inspired by the Chromium Origin Trial process.

Traditionally, a feature in experimental mode can only be used in development and cannot be pushed to production. Origin Trials allow interested developers to opt-in to a test an experimental feature in production. Origin Trial users should be mindful of the following:

The test is for a limited time.
The feature will likely undergo some changes after an Origin Trials.
Origin Trials present an opportunity to implement and benefit from a new feature before it’s fully live. The feature will live on the developer's site, rather than guarded by an experiment, and feedback can directly influence the direction of the feature.

When to consider an Origin Trial

Not every experiment needs an Origin Trial.
The experiment should be feature complete with a stable API at the point of the Origin Trial.
Data from opt-in experiments is going to be insufficient and you need data from real-world users.
The potential versioning pain is much greater than the pain of dealing with the logistics of an Origin Trial.
Good questions to answer with an Origin Trial:
- Is this API the "right" one?

Origin Trial - the details

No Origin Trial can last more than 3 months.
An Origin Trial duration can be prematurely shortened by us (with 7 days of notice) if usage exceeds 0.1% of AMP page loads.
Extending an Origin Trial requires approval from the Approvers Working Group (@ampproject/wg-approvers).
