How it works

1. Create a BrowserSolver account and copy your API key from the dashboard.
2. Call https://api.browsersolver.com with the header x-api-key: YOUR_API_KEY.
3. Use the result in your app — no infrastructure to run.

export BROWSERSOLVER_API_KEY="your-api-key"
pip install requests        # Python
# TypeScript: Node.js 18+ (native fetch), run with `npx tsx file.ts`

  cms?: unknown;
  urls?: {
    "https://vercel.com/"?: {
      status?: number;
    };
  };
  technologies?: string[];
};

const headers = { "x-api-key": process.env.BROWSERSOLVER_API_KEY!, "Content-Type": "application/json" };

const params = new URLSearchParams({
  "query": "https://www.shopify.com/",
});

const response = await fetch(`https://api.browsersolver.com/v1/website/technology?${params}`, { headers });
if (!response.ok) throw new Error(`HTTP ${response.status}: ${await response.text()}`);

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

Use cases

• Lead enrichment — Add CMS and stack data to company records in your CRM.
• Prospecting — Find sites that run a given CMS, analytics tool or CDN.
• Competitive research — See which frameworks and tools competitors rely on.
• Security inventory — List the security tooling and versions exposed by your domains.

Why BrowserSolver?

• Three fetch tiers — Crawler for static HTML, Rendering for JavaScript pages, WebUnlocker for hosts that still challenge a headless browser.
• Know before you fetch — the Antibot endpoint names the bot-protection vendor in front of a URL so you can choose the right tier.
• Screenshots as a service — PNG, JPEG, WebP or PDF, full page, 18 device presets, cookie banner and ad removal, S3 upload.
• Technology detection — CMS, frameworks, analytics, CDN and security tooling of any public URL.
• Copy-paste examples — Python and TypeScript in each README, 7 more languages in examples/.
