If you are using Vercel then you can integrate Upstash Redis, Kafka or QStash to your project easily. Upstash is the perfect serverless solution for your applications thanks to its:

  • Low latency data
  • Per request pricing
  • Durable storage
  • Ease of use

Below are the steps of the integration.

Add Integration to Your Vercel Account

Visit the Upstash Integration on Vercel and click the Add Integration button. Choose your scope and application that you want to integrate.

Select Your Project

Vercel will redirect you to Upstash, where you can select your Vercel project and Upstash resources that you want to integrate.

If you do not have a Redis database or Kafka cluster yet, you can create one from the dropdown menu.

Once you have selected all resources, click the Create button at the bottom of the page.

After all environment variables are created, you will be forwarded to Vercel. Go to your project settings where you can see all added environment variables. Depending on the resources you selected, you will see something similar to this:

You need to redeploy your app for the environment variable to be used.

Create Your Redis Client

If you completed the integration steps above and redeploy your app, the added environment variables will be accessible inside your Vercel application. You can now use them in your clients to connect


const { Redis } = require("@upstash/redis");

module.exports = async (req, res) => {
   * Redis.fromEnv() will read the following from environment variables:
  const redis = Redis.fromEnv();
  await redis.set("foo", "bar");
  const bar = await redis.get("foo");

    body: `foo: ${bar}`,


import { Kafka } from "@upstash/kafka";

const kafka = new Kafka({
  url: process.env.UPSTASH_KAFKA_REST_URL,
  username: process.env.UPSTASH_KAFKA_REST_USERNAME,
  password: process.env.UPSTASH_KAFKA_REST_PASSWORD,

await kafka.producer().produce("my-topic", "my-message");



import { Client } from "@upstash/qstash";

const c = new Client({
  token: process.env.QSTASH_TOKEN,

const res = await c.publishJSON({
  url: "https://my-api...",
  body: {
    hello: "world",


import { Receiver } from "@upstash/qstash";

const r = new Receiver({
  currentSigningKey: process.env.QSTASH_CURRENT_SIGNING_KEY,
  nextSigningKey: process.env.QSTASH_NEXT_SIGNING_KEY,

const isValid = await r.verify(
  signature: "..."
  body: "..."
