What it does

Everything a prompt needs
between the idea and production.

Full version history

Every edit is a commit. Diff any two versions, leave notes, and roll back to a previous prompt in one click.

Variables & templating

Define typed {{variables}} once and reuse prompts across products. Cueno validates inputs before they ship.

Environments

Promote a prompt from draft → staging → production. Test changes safely without touching live traffic.

Evals & A/B testing

Score prompts against test cases and run live experiments. Let the numbers pick the winning version.

Review & approve

Open changes for review, gather comments, and require sign-off before a prompt reaches production.

Typed SDK & REST

Fetch the right prompt for the right environment with one call. Edge-cached, fully typed, framework-agnostic.

The workspace

One place for every prompt.

No more prompts buried in code, Notion docs, and Slack threads. Edit with live variable previews, watch the history build itself, and check scores before anything ships.

# welcome-support · production

You are {{agent_name}}, a warm, concise support
agent for {{company}}.

Greet {{customer}} by name and resolve
their issue in three sentences or fewer.

app/route.ts

import { Cueno } from "@cueno/sdk";

const cueno = new Cueno({ apiKey: process.env.CUENO_API_KEY! });

// the key's env picks the live version
const { prompt } = await cueno.prompts.render("welcome-support", {
  company: "Acme",
  customer: user.name,
});

const reply = await model.run(prompt);

Ship it

From the editor to your app in one call.

Edit prompts without a redeploy. Cueno serves the right version for each environment over an edge cached, fully typed SDK. Change a prompt and it goes live in seconds, with a clean audit trail behind it.

$npm i @cueno/sdk

Why Cueno

Stop shipping prompts blind.

Pull prompts out of code and spreadsheets into one place that is reviewed, tested, and versioned. Every change is on purpose and every rollback is one click.
