How to Look Up Any Company's Tech Stack Programmatically

Why Tech Stack Data Matters

Knowing what technologies a company runs gives you a serious edge. Sales teams use it to qualify leads ("Do they already use a competitor?"). Developers use it to scope integrations. Recruiters use it to match candidates to the right environments.

Manually browsing StackShare profiles doesn't scale. The StackShare Tech Stack API lets you pull that data programmatically — one request per company, structured JSON back.

What You Get

Hit the /api/company/stack endpoint with a company name and you get back their full technology stack: languages, frameworks, databases, DevOps tools, SaaS products, and more. The response includes tool names, categories, and adoption context — everything you need for B2B intelligence pipelines.

Quick Example

Here's how to fetch Spotify's tech stack with a single fetch() call:

const response = await fetch(
  'https://stackshare-tech-stack-api.p.rapidapi.com/api/company/stack?companyName=spotify',
  {
    headers: {
      'x-rapidapi-key': 'YOUR_RAPIDAPI_KEY',
      'x-rapidapi-host': 'stackshare-tech-stack-api.p.rapidapi.com'
    }
  }
);

const data = await response.json();
console.log(data);

Swap spotify for any company — airbnb, shopify, stripe, slack — and get their stack back instantly.

Use Cases That Actually Ship

Lead scoring: Enrich your CRM pipeline. If a prospect uses React and you sell React tooling, that's a warm lead. Automate the check.

Competitive analysis: Track what tools competitors adopt quarter over quarter. Feed the data into dashboards or Notion databases.

Recruiting platforms: Show candidates which companies use the frameworks they know. Match people to stacks, not just job titles.

Market research: Aggregate adoption data across hundreds of companies to spot technology trends before they hit Hacker News.
