Cueno - prompt management for devs

Cueno is an AI developer tool that acts as a prompt management system, giving teams a single, versioned place to store, test, and deploy the prompts their applications send to language models. Instead of scattering prompts across code, Notion docs, and Slack threads, developers manage them in Cueno with full edit history and one-click rollbacks, variables and templating with input validation for reusable prompts, and environment promotion that moves a prompt from draft to staging to production. It includes evaluation and A/B testing to compare prompt versions, plus review and approval workflows so changes are checked before they reach production. A typed SDK and REST API fetch prompts at runtime with edge caching, which lets teams ship prompt changes without redeploying the application. It is aimed at developers and AI teams running prompts at scale who need versioning, testing, and governance around their prompts. The site offers a free tier ("Start for free"); specific paid pricing is not detailed on the reviewed page.

Centralized version control, testing, and deployment of LLM prompts for developers and AI teams running prompts at scale.
