Prompt registry
Treat prompts like code releases, not scattered strings.
A prompt buried in your codebase has no version history, no review, and no way to roll back. VernaOne makes every prompt a named, versioned endpoint you can review, compare, promote, and revert — instantly.

Prompts-as-strings have no release process
When prompts live as inline strings, changing one means a code deploy, there's no diff of what actually changed in the wording, and rolling back a regression means finding and reverting the right commit under pressure.
There's also no single source of truth: the same prompt gets copied into three services and drifts.
How the registry works
- 1
Named, versioned endpoints
Each prompt is a named endpoint with typed {{variables}}. Every change is an immutable version you can review and compare against previous ones.
- 2
Activate & roll back
Promote any version to active with a click; production always points at the exact version you choose. If a new version underperforms, roll back instantly.
- 3
Lifecycle controls
Gate execution with active, paused, and inactive states so only approved prompts run — and a misbehaving prompt can be paused in seconds without losing history.
- 4
Call by name from code
Your application invokes the prompt by name over HTTP or the SDK, so you ship prompt updates without redeploying application code.
Highlights
Immutable versions
Every edit is a reviewable, comparable version you can roll back to.
One-click activate/rollback
Production points at the version you choose; revert a regression instantly.
Lifecycle states
Active, paused, inactive — only approved prompts execute.
Typed inputs
Declare variables with types and required flags so bad inputs are caught before you pay for a call.
Because production calls a prompt by name, you ship prompt changes without a code deploy — and lifecycle states let you pause a bad prompt the moment you spot it.
Ship on this — free to start.
Author a prompt once and call it by name. VernaOne handles the model, the fallback, the cost, and the alerting.

How is a prompt version rolled back?
Every change is stored as an immutable version. You promote any version to active with a click, and production immediately points at it — rolling back is just activating the previous version.
Do prompt changes require a code deploy?
No. Your code calls the prompt by name; updating or rolling back a version takes effect server-side without redeploying your application.
Can I stop a prompt from running?
Yes. Set it to paused or inactive and it rejects execution while keeping its full version history — useful for containing a misbehaving prompt or a decommissioned model.
