Amazon OpenSearch Serverless is now available in the Vercel Marketplace, with guided setup and automatic project configuration built into the Vercel dashboard.

Link to headingBuilt for agentic infrastructure

By bringing Amazon OpenSearch Serverless into the Vercel Marketplace, teams benefit from a unified workflow:

  • In-dashboard provisioning: Spin up OpenSearch collections directly from the Vercel dashboard

  • Automatic configuration: Environment variables are automatically injected into your projects on provisioning

  • Unified management: View and manage search resources alongside the rest of your application infrastructure in the Marketplace resource view, with quick links to AWS for deeper configuration

lib/opensearch.ts
import { createOpenSearch } from '@vercel/aws';
const os = createOpenSearch();

An OpenSearch client authenticated through Vercel OIDC, with no static AWS keys.

app/api/ask/route.ts
import { opensearch } from "@/lib/opensearch";
import { embed, generateText } from "ai";
export async function POST(req: Request) {
  const { question } = await req.json();
  // Turn the question into a vector
  const { embedding } = await embed({
    model: "openai/text-embedding-3-small",
    value: question,
  });
  // Retrieve the 5 most semantically similar docs
  const { body } = await opensearch.search({
    index: "docs",
    body: {
      size: 5,
      query: { knn: { embedding: { vector: embedding, k: 5 } } },
    },
  });
  const context = body.hits.hits
    .map((h: any) => h._source.content)
    .join("\n\n");
  // Answer grounded in the retrieved context
  const { text } = await generateText({
    model: "anthropic/claude-sonnet-4-5",
    prompt: `Answer using only this context:\n\n${context}\n\nQuestion: ${question}`,
  });
  return Response.json({ answer: text });
}

A RAG route that embeds the question, retrieves the top-5 nearest documents from OpenSearch, and answers grounded in them.

This integration is powered by the next generation of Amazon OpenSearch Serverless APIs, with Vercel participating as a key design partner alongside AWS during development.

  • Unified support for vector, lexical, hybrid, and agentic search in a single collection

  • Autoscales up to 20× faster, built for the bursty, unpredictable load patterns of agentic workloads

  • Scale to zero with no idle costs

  • Up to 60% cost savings by paying for actual usage instead of peak capacity
