Companies Using Elastic APM

Elastic APM is mostly invisible from outside. Its Java, .NET, Node.js and Python agents run inside a company's servers, and nothing about them reaches a web page. What our crawl can see is the browser half: Elastic's real user monitoring (RUM) agent, which creates an elasticApm object on every page it runs on. In October 2026 that object turned up on 11,065 live domains. More than half of them didn't choose Elastic, so this page counts 5,189, and we matched 2,022 of those to a company.

Why we removed half the count

I loaded a random 100 of the raw domains in a browser. About 20 were a business running the agent on its own site or app. Most of the rest were platforms that ship the agent to every customer: dealer websites for motorcycles, boats and farm equipment, small web hosts selling GoDaddy products from GoDaddy's storefront, auto-repair shop sites and university logins on D2L's Brightspace. Measured across the whole set, those fleets come to 5,844 domains: GoDaddy 1,971, Dealer Spike 1,493, a second dealer platform 1,401, KUKUI 725, Brightspace 132 and 129 cloned betting pages. On Brightspace the agent reports to D2L's own Elastic Cloud deployment, so the university hosting the login page isn't the customer. The end of this page lists how each fleet was identified.

Sales signal: the raw 11,004 in our API is not Elastic's customer count. The 5,189 here is the list where a buyer chose Elastic, or at least chose a builder or agency that did.

Growth trajectory

The chart has one point, 5,189 in October 2026, because our earlier monthly totals include the fleets. I won't read a trend from a single month. When later points arrive, remember that the set of domains we crawl turns over every month, as dead sites drop out and new ones come in, and our detection widens over time. Churn is meaningful even if the raw figure overstates it: 1,826 domains have dropped the agent since we began tracking it in March 2026, a count that includes fleet sites, and 413 of them still run it on another hostname.

"Half of Elastic APM's browser footprint was website platforms installing the agent for thousands of small businesses. Take them out and what's left looks much more like Elastic's own market: banks, telecoms and retailers, several running their own APM servers." - David Thomson, CTO at TechnologyChecker.io

Sales signal: watch the cleaned count from month to month. A single platform in the raw count carries up to 1,971 domains, so one vendor decision there can swamp every real sale.

Who the customers are

41.55% of matched companies with a known headcount have 1 to 10 employees and 20.64% have 11 to 50, and the 2010s (36.12%) are the largest founding decade. Restaurants and real-estate firms on shared templates account for part of the small end. The large end is different: 179 matched companies employ more than 1,000 people, 9.82% of those with a known size. Among them, banks, financial services firms and insurers add up to 37, telecoms 17, government bodies 12 and universities 8.

Several large users send RUM data to an endpoint on their own domain, which means an APM server they operate. KBC reports to es6-elasticapm.kbc.be, Mercadona to a host on mercadona.es, MegaFon to a path on megafon.ru, Liberty University to apm.liberty.edu and ENGIE Belgium to its own site. Texas A&M and Siloam Hospitals do the same. HP, EPAM, LEGO, Safaricom, Veeam and Allianz UK also ran the agent when I loaded their pages.

Sales signal: a self-hosted RUM endpoint is a strong hint that the company runs Elasticsearch for observability. That's the account for Elastic consultancies, managed Elastic hosts and anyone selling cost or migration help away from a self-run stack.

Industries and countries

Restaurants lead the industry chart at 10.09%, but 149 of the 181 are ordering sites in the UK, Poland and Brazil. Finance is the more useful block: Financial Services (4.8%), Insurance (3.23%) and Banking (2.79%) add up to 194 of the 1,794 companies with a known industry. The United States has 495 of the 2,022 matched companies, then Brazil (178), the United Kingdom (156), Australia (113) and Poland (109). The Netherlands (92), Germany (85), France (75), Romania (59) and Belgium (55) follow, and 42 of the Romanian companies are in real estate.

Sales signal: for enterprise prospecting, look at Belgium, Spain and Latin American telecoms. KBC, ENGIE Belgium, Mercadona, Securitas Direct, Vivo, Entel and Tigo in Colombia all appear in the list.

Switching patterns

The migration table was counted before the cleanup, so it's raw. Since March 2026, 62 domains dropped Sentry and run Elastic APM, and 58 went the other way; 9 of those 58 still run Elastic on another hostname. New Relic is the clearest net gain for Elastic, 48 domains in against 27 out, and Datadog 25 against 14. Akamai mPulse runs slightly against Elastic, 14 in and 18 out. These are domains, not companies, and a platform switching vendors can move many at once, so I read the table as churn at the edges.

"Sentry and Elastic trade sites almost one for one, and 395 of the cleaned Elastic domains run Sentry as well. That looks like coexistence to me." - David Thomson, CTO at TechnologyChecker.io

Sales signal: New Relic accounts that added Elastic's agent are the most interesting rows for Elastic's sellers; for New Relic, Datadog and Sentry, the self-hosted Elastic accounts are the competitive list.

The stack around it

These shares are of the 5,189 live domains in our clean set. Next.js runs on 31.03%, React on 12.49%, Vue.js on 11.16% and Angular on 9.85%: single-page front ends, which is where browser monitoring earns its place. Microsoft ASP.NET (9.02%) and Ruby on Rails (3.87%) are the larger back-end signals. Cloudflare fronts 38.43% and Amazon Web Services hosts 16.46%. Adobe Analytics (3.57%) and Matomo (2.99%) sit beside Google Analytics, which is on 66.62%.

Sales signal: Next.js and Angular shops running Elastic RUM are candidates for front-end performance and error-tracking pitches.

What it costs

Elastic's self-managed pricing page lists APM, logging and metrics in the free tier, and the RUM agent is open source under the MIT licence. Elastic Cloud Hosted starts at $99 a month for Standard, and Observability Serverless charges from $0.07 per GB ingested (checked 10 October 2026).

Sales signal: the free tier means many self-installed accounts pay Elastic nothing. Ask whether the company is self-managed or on Elastic Cloud before pricing a migration.

Key takeaways

1. 5,189 live domains in October 2026 after removing 5,844 platform-fleet sites, and still a floor.

2. The raw 11,004 in our API is mostly not Elastic's buyers.

3. The enterprise tail is banks, insurers, telecoms and government, several running their own APM server.

4. 0.19% of APM & Error Tracking, 14th of 58 on the cleaned count, in a category Sentry holds at 70.51%.

5. Raw switching is roughly even with Sentry and slightly in Elastic's favour against New Relic and Datadog.
