What companies use Cloudflare? A website scan sees it on almost every response, and job postings show who builds on it. Here is the list and the method. ![Dvir Atias](/authors/dvir-atias.jpg) Dvir Atias Founder, JobsPipe What companies use Cloudflare? Two public signals answer it. A website scan sees Cloudflare on almost any site that sits behind it, because response headers and nameservers give it away. Job postings show which companies build on it, with its developer platform or security products named in the role. Here is what postings say, and how to combine both signals. The employers with the most active postings naming Cloudflare, as of 2026-09-09: - Cloudflare - Deepgram - Lovable - turing - HERCULES - Focus Group - Rippling - Wordware - Method Financial - Genki The postings list is short next to the website signal: <0.5% of active postings name Cloudflare, because most staff at a company behind Cloudflare never touch it. The names that do appear are companies staffing teams that build on it, plus Cloudflare itself, whose own postings name its products. The full list is on the [companies using Cloudflare](/companies-using/cloudflare) page. ## How to find out what companies use Cloudflare 1. **Scan the website first.** Call `POST /v1/stack/scan` with the domain. A site behind Cloudflare typically answers with a `server: cloudflare` header and a `cf-ray` header, and its nameservers point at Cloudflare. The scan reports the detection with a confidence score. This is the broad signal, and it covers companies that never post a role naming the product. 2. **Search postings for the builders.** Call `POST /v1/jobs/search` with `skills_or` set to `["cloudflare"]`. These are engineering, platform and security roles, and each row’s `technology_slugs` shows what sits next to Cloudflare in the same posting. 3. **Separate customer from vendor.** Cloudflare’s own postings dominate any skill search for its name. Drop them with the company field, then read the rest: a posting that lists Cloudflare among ten tools is weaker evidence than one that asks for experience building on it. 4. **Cut by industry and size.** Use `isic_division_or` and the employee count filters, or read the chart below. Postings naming Cloudflare skew towards software companies, but the size bands show it is not a small-company story alone. 5. **Watch for change.** Rerun with `discovered_at_gte`. A first posting naming Cloudflare at a company whose site already runs behind it is a sign the team is building on it rather than only routing traffic through it. - Software and IT services24.0% - Employment and staffing5.8% - Financial services4.0% - 1000+ employees30.2% - 201-1000 employees13.0% - 1-50 employees4.7% - 51-200 employees3.8% Share of active postings naming Cloudflare, by employer industry (top five ISIC divisions) and by employer size band. Size bands omit postings whose employer headcount is unknown. How this was measured Measured from active postings on the ten collected boards whose text names the technology (deduplicated by posting id). Generated 2026-09-09. Shares only: JobsPipe publishes percentages, not counts. A posting counts once per technology its text names. Industry is the ISIC Rev.4 division of the employer on each posting; size is the employer’s headcount band where known, so the size bars do not sum to 100%. Shares are cross-sectional for the current active set. ``` curl -X POST https://api.jobspipe.dev/v1/jobs/search \ -H "Authorization: Bearer $JOBSPIPE_API_KEY" \ -H "Content-Type: application/json" \ -d '{"skills_or":["cloudflare"],"status":"active","limit":25}' ``` How many companies use Cloudflare? Postings cannot count companies, and for Cloudflare they understate adoption more than for most technologies, since the product works without anyone being hired for it. Treat the posting share as a floor on the builders and the website scan as the measure of the customer base. What a stack is, and why the two signals differ, is in [what is a tech stack](/blog/what-is-a-tech-stack). ## Where JobsPipe fits JobsPipe is a jobs data API that collects live postings from LinkedIn, Indeed, Y Combinator, Naukri, Workday, Greenhouse, Workable, SmartRecruiters, Ashby, Lever and Paylocity, returns them as one schema with closure tracking and a ghost score, and includes a free tier of 1,000 jobs a month. The same key runs the website scan at [jobspipe.dev](https://jobspipe.dev): ``` curl -X POST https://api.jobspipe.dev/v1/stack/scan \ -H "Authorization: Bearer $JOBSPIPE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "domain": "example.com", "mode": "auto" }' ``` The response lists detected technologies with categories and confidence. Pair it with a postings search on `skills_or` and you have both sides of the answer. The scan is documented on the [stack scan page](/stack). Scan a domain and search its postings on one key - free tier included. ![](/listly/shape-heart.png) FAQs ## Frequently Asked Questions ### Which companies use Cloudflare? As of 2026-09-09, employers with the most active postings naming Cloudflare include Cloudflare, Deepgram, Lovable, turing, HERCULES. Postings catch the teams building on Cloudflare; a website scan catches the far larger set of companies whose sites simply sit behind it, since the response headers and nameservers reveal it. ### How many companies use Cloudflare? No public count exists. In JobsPipe's collection <0.5% of active postings name Cloudflare, a minority of postings and a floor on the builders rather than a count of customers, since most companies behind Cloudflare never hire for it. The website scan is the better measure of the customer base. ### Can a website scan detect Cloudflare? Usually, yes. A site behind Cloudflare typically returns a server header naming it and a cf-ray header, and its nameservers point at Cloudflare. POST /v1/stack/scan reports the detection with a confidence score alongside the other technologies on the public site. What it cannot see is the developer platform work, which only postings reveal.
