grayWyre V2.0 is live. Now with granular RBAC.

Your prompts ship to production. Version them like it.

Prompt drift is silent. No stack trace, no alert — just subtly wrong AI outputs until someone notices. grayWyre gives your team version control, diffs, and one-click rollback for every prompt you ship.

Give your prompts the same rigor you give your code.

Your LLM outputs are only as reliable as your prompt discipline. grayWyre makes that discipline effortless.

Version Control & Rollback

Every save creates an immutable version with a full diff. When outputs degrade, you know exactly what changed and can revert in one click.

REST API for Prompt Resolution

Pull active prompts by name via API, with variable substitution resolved server-side. Your app always runs the current approved prompt — no deployment required.

Test with Real Models (BYOK)

Run prompts directly in grayWyre using your own API keys. Test with real model behavior before you publish — no copy-paste into a separate playground.

Audit Trail & RBAC

Every change is attributed to a user with a timestamp. Roles control who can edit vs. who can publish. Know who changed what and when.

Governance doesn't stop at the model.
It starts at the prompt.

Most organizations don't know which prompts are running in production right now, when they were last changed, or whether the prompt the team tested is the same one the app is using.

grayWyre gives engineering and compliance teams a single governed layer for every prompt in the organization. Role-based access, complete version history, and active/draft status gates — nothing goes live by accident.
