Preview programs Early access
Use it before it ships.
Preview programs give your team new Fantasti features while they are still being built. You choose which previews to join, per organization. Each one states its stage, what it costs, how it is supported and what may still change.

Five stages, defined once.
Status tags and the changelog use these words, with these meanings.
BY REQUEST is not a stage. It marks products sold on reserved terms through sales, such as rack-scale systems.

Join per organization.
An organization admin asks to join a preview from this page. Previews that need approval show Requested until we admit you. Leave at any time.

# { "slug": "workspaces", "stage": "early-access", "state": "requested" }An organization moves through four states in a preview: not_joined, then requested while a preview that needs approval waits for us to admit you, then joined, then left when you leave. A preview that needs no approval goes from not_joined straight to joined. The join call answers with the state as a literal. Connections: not_joined to requested: Join; requested to joined: Admitted; joined to left: Leave; not_joined to joined: No approval needed.

Questions about previews.
Is a preview safe for production?
Early access is not. Private Preview and Public Preview run real workloads, without the commitments of General Availability unless your contract states them.
Do previews cost money?
Each preview states its billing. Private Preview and Public Preview features are billed at published or quoted rates.
What happens to my resources when a preview ends?
We announce the end in the changelog, with the date and the path forward: migrate, export or continue on the released feature.
How do I hear about new previews?
Follow the changelog, filter it by stage, or subscribe to the feed.
Can I ask for something that does not exist yet?
Propose it in Feedback. An idea that reaches Planned may open as early access with the teams who asked.
