How to Look Up Any Company's Tech Stack with a Single API Call

#api #saas #webdev #javascript

Ever wished you could instantly find out what technologies a company uses — their frameworks, databases, cloud providers, and dev tools — without manually digging through job postings and LinkedIn profiles?

The StackShare Tech Stack API gives you exactly that. Pass in a company name and get back structured data on every tool in their stack. It's built for developers working on B2B sales intelligence, competitive analysis, lead enrichment, and market research.

What It Does

The API scrapes and aggregates technology adoption data from StackShare. You send a company name, and it returns the tools that company uses — organized by category. Think of it as programmatic access to the "What does Company X use?" question.

Use cases:

  • Sales teams: Qualify leads by tech fit. Selling a React component library? Find companies already using React.
  • Competitive intel: Track what tools competitors adopt and when they switch.
  • Market research: Aggregate adoption trends across hundreds of companies.
  • Recruiting: Understand a company's stack before interviewing.

Quick Start

Here's how to fetch Airbnb's tech stack with a single call:

const response = await fetch(
  'https://jobs-intelligence-api-production.up.railway.app/api/stackshare-tech-stack-api/company/stack?companyName=airbnb',
  {
    method: 'GET',
    headers: {
      'Content-Type': 'application/json'
    }
  }
);

const data = await response.json();
console.log(data);
Enter fullscreen mode Exit fullscreen mode

The response includes tools grouped by layer — application & data, utilities, DevOps, and business tools — so you can immediately filter for what matters to your workflow.

Build Something With It

A few ideas to get started:

  • CRM enrichment pipeline: Automatically tag leads in your CRM with their tech stack when a new contact is added.
  • Competitor dashboard: Pull stacks for your top 10 competitors nightly and alert on changes.
  • Prospecting filter: Build an internal tool that finds all companies using a specific technology.
