§ 01What it does
Everything a prompt needs
between the idea and production.
№ 02
Variables & templating
Define typed {{variables}} once and reuse prompts across products. Cueno validates inputs before they ship.
№ 03
Environments
Promote a prompt from draft → staging → production. Test changes safely without touching live traffic.
№ 04
Evals & A/B testing
Score prompts against test cases and run live experiments. Let the numbers pick the winning version.
№ 05
Review & approve
Open changes for review, gather comments, and require sign-off before a prompt reaches production.
№ 06
Typed SDK & REST
Fetch the right prompt for the right environment with one call. Edge-cached, fully typed, framework-agnostic.
§ 02 — The workspace
One calm home for every prompt.
No more prompts buried in code, Notion docs, and Slack threads. Edit with live variable previews, watch the full history build itself, and measure quality before anything ships.
- Live preview as you type
- Side-by-side version diffs
- Built-in test cases & scoring

import { Cueno } from "@cueno/sdk"; const cueno = new Cueno({ apiKey: process.env.CUENO_API_KEY! }); // the key's env picks the live version — server renders it const { prompt } = await cueno.prompts.render("welcome-support", { company: "Acme", customer: user.name, }); const reply = await model.run(prompt);
§ 03 — Ship it
From the editor to your app in one call.
Edit prompts without redeploying. Cueno serves the right version for each environment over an edge-cached, fully-typed SDK — change a prompt and it's live in seconds, with a clean audit trail behind it.
§ 04 — Why Cueno
Book a demo →Stop shipping prompts blind.
Pull prompts out of code and spreadsheets and into one reviewed, tested, versioned home — so every change is intentional and every rollback is instant.
