ATS Detector: which job board (applicant tracking system) does a company use?

Give it a list of company websites; get back which ATS each company uses (Greenhouse, Lever, Ashby, Workable, Recruitee, SmartRecruiters, BambooHR, Personio), its public career page, how many roles are open, its top hiring teams and countries, and the date of its latest posting.

Companies already in our daily database (1,250+ job boards) are answered instantly; others are detected live from their website and career page.

Who uses it

• HR-tech and recruiting software sales: know which ATS a prospect runs before you call (competitor displacement, integrations, partner lists).
• Recruiters and agencies: find the right career page and see how actively a company hires.
• Job aggregators and data teams: map companies to their job board feeds.
• Market research: ATS market share across a list of companies.

Example

{ "companyWebsites": ["stripe.com", "vanta.com", "notion.so", "ramp.com"] }

Output

Field	Example
website, company	https://www.vanta.com, Vanta
ats, ats_name, board	ashby, Ashby, vanta
careers_page	https://jobs.ashbyhq.com/vanta
open_jobs, remote_share	120, 0.35
top_departments, hiring_countries, latest_posting	["Engineering", "Sales"], ["US", "IE"], 2026-10-01
company_industry, company_team_size, source	B2B, 800, database / live

Websites where no supported ATS was found are listed in the run's key-value store under NOT_FOUND with the reason, and are not billed.

Pricing

Pay per event: one company found (with its ATS). Not-found websites are free. Max 100 websites per run.

FAQ

How is the ATS detected? From links on the company's website and careers page, plus checks of the ATS vendors' public job board endpoints, with a name check to avoid matching a different company with the same slug.

What if a company uses another ATS (e.g. Workday, iCIMS)? It is reported in NOT_FOUND for now.

Data and use

Only public company and job-board information. No personal data.

What you can do with it

• Detect which ATS a company uses: Greenhouse, Lever, Ashby, Workable, Recruitee, SmartRecruiters, BambooHR or Personio
• Find a company's official careers page and job board URL from its website
• Build lead lists for HR-tech, recruiting software and ATS integrations
• Measure ATS market share across a list of companies or a portfolio
• Map companies to job board feeds for job aggregators
• Check how many roles a company has open and where it hires before you reach out

What it costs

Example	Cost
100 company websites (all found)	about $1.00
1,000 websites over 10 runs	about $10.00

You only pay for rows you get. Set Max results (or a maximum cost per run in Apify) to cap spend. Apify's free plan includes monthly credit, so you can try it at no cost. Apify subscribers get automatic Store discounts on some events.

Use it from code, no-code tools or AI agents

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("worthwhile_quinsy/ats-detector").call(run_input={'companyWebsites': ['stripe.com', 'notion.so']})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / Node.js (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });
const run = await client.actor('worthwhile_quinsy/ats-detector').call({"companyWebsites": ["stripe.com", "notion.so"]});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

One HTTP call (returns the rows directly):

curl -X POST 'https://api.apify.com/v2/acts/worthwhile_quinsy~ats-detector/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{"companyWebsites": ["stripe.com", "notion.so"]}'

No-code: connect it to Make, Zapier, n8n, Google Sheets, Slack or a webhook from the Integrations tab, and run it on a Schedule (for example every morning).

AI agents (MCP): use it as a tool in Claude, ChatGPT, Cursor or any MCP client through the Apify MCP server: https://mcp.apify.com?tools=worthwhile_quinsy/ats-detector. Your agent can then ask for live job data in plain language. Use this tool when the user asks for which applicant tracking system or careers page a company uses, given its website.
