LaunchDarkly is used by 37,315 companies worldwide, including Burger King Company LLC, Subway, Sanofi, based on our analysis of 29.6M crawled domains at TechnologyChecker.io. It's particularly popular in the Retail industry (13.44% of customers).

LaunchDarkly has 37,315 active customers detected through our full-sweep crawl of 29.9M live business domains. We enriched 27,002 of these with LinkedIn company data on TechnologyChecker.io to generate detailed insights. An additional 6,613 sites that previously used LaunchDarkly are also tracked.

LaunchDarkly holds 97.1% of the Feature Flags market, ranking #1 in the category — based on our analysis of 29.6M domains and 40K+ technologies at TechnologyChecker.io.

The top alternatives to LaunchDarkly include FlagSmith (1.43% market share), Beamer (1.41% market share), LaunchNotes (0.06% market share) — based on our market share data across 29.6M crawled domains.

United States leads with 21,489 LaunchDarkly customers, followed by Australia (2,125), Canada (903), United Kingdom (429), Netherlands (255), based on our enriched company data at TechnologyChecker.io.

The most common company size is 1-10 employees, representing 47.69% of LaunchDarkly customers, based on our analysis of 27,002 enriched companies. This is followed by 11-50 employees (30.09%) and 51-200 employees (13.85%).

The majority of LaunchDarkly customers were founded in the 2010s (28.33%), followed by the Pre-1960 (16.23%), based on our analysis of 27,002 enriched companies. This suggests LaunchDarkly is most popular among relatively young companies.

The ideal LaunchDarkly customer is: Company Size: 1-50 employees, Location: United States, Industry: Retail, automotive, real estate, Founded: 2010-2019, Stack: Modern JavaScript — based on our analysis of 27,002 enriched companies at TechnologyChecker.io.

Our crawl detects LaunchDarkly on 37,315 domains as of August 2026, and we matched 27,002 of them to company records for a 72.4% match rate. Detection combines a DNS verification record created during account setup with runtime SDK signals in the page, so a listed domain is genuinely connected to an account.

It is 97.1% of the feature flag category we track, but that category is small and the figure needs context. It contains only four detectable technologies and 38,428 domains in total, with FlagSmith on 548 domains and Beamer on 543. Most feature flagging is built in-house and leaves no detectable signature at all.

Large consumer brands more than software firms. Retail leads the industry mix on 13.44%, then motor vehicle manufacturing on 8.56%, real estate 6.96% and hospitality 4.44%. Burger King, Subway, CVS, Sherwin-Williams and Edward Jones all appear, which is not the audience most people associate with a developer tool. Only two of the ten largest detected organisations are software companies.

Because the unit of detection is a domain, not a corporation. 47.69% of domains map to companies with ten staff or fewer, but enterprises frequently run flags on campaign, brand and regional sites whose registered company record is a small subsidiary rather than the parent organisation that actually holds the contract.

Through four signals. There is a DNS TXT verification record set when a domain is added to an account, a stylesheet or link reference to a LaunchDarkly host, a JavaScript global exposed by the client SDK, and matching script sources. The DNS record is the strongest of these because it implies an actual account relationship.

Reasonably, with one caveat we publish openly. 29.5% of active LaunchDarkly domains have been seen only once by our crawler, the highest single-sighting rate in this wave, against a corpus norm nearer 10 to 20%. The core of the dataset is solid, but expect some churn in the long tail of small domains.

They run modern JavaScript. core-js appears on 90.96% of sampled domains, Google Tag Manager on 84.52%, Google Analytics on 82.32% and React on 27.89%. Those co-occurrence rates are far higher than the other technologies in this wave produce, indicating current build tooling rather than inherited themes or templates. Compare that with Font Awesome, where jQuery leads on 40.6% and the stack looks a generation older.

In our data, almost nothing at comparable scale. FlagSmith appears on 548 domains and Beamer on 543, against LaunchDarkly's 37,315. The genuine alternatives are invisible to detection: teams building their own flag systems, or using flagging bundled inside a deployment platform or an experimentation tool we classify in another category.

Later than the company's founding suggests. Our history records two domains in February 2015 and only six by January 2019. Growth becomes meaningful from 2022, reaching 1,176 domains that January and 6,131 by April 2025 in our long-run feed. The current live crawl, a different measurement system, records 37,315. Read the step between those two figures as changed coverage, not one year of growth.

More than you would expect for a developer tool. 16.23% of enriched LaunchDarkly customers were founded before 1960, alongside 15.26% founded in the 2000s and 28.33% in the 2010s. Progressive delivery has clearly spread beyond technology companies into established consumer brands with continuous release cycles. The largest detected organisations include Burger King, Subway, CVS, Sherwin-Williams and Mayo Clinic, none of which are technology firms.

Because there is nothing meaningful to report. LaunchDarkly's category rivals are so small, at 548 and 543 domains against its 37,315, that no in-category switching flow reached a volume we would publish. Rather than present a table built on a handful of domains, we leave the section out entirely. A table built on a handful of domains would imply a precision the underlying data cannot support.

We have observed 6,613 domains stop showing LaunchDarkly signals since our crawler began covering it in April 2026. Some of that is genuine churn and some reflects the intermittent detection noted above, since a domain whose SDK loads conditionally may not register on every crawl of the site. Against 37,315 active domains, that is churn observed across a few months rather than a lifetime total.

Yes. This page ranks the largest by audience size, and TechnologyChecker.io holds the full set of 37,315 detected domains with company records attached to 27,002 of them. Those rows carry industry, headcount band, country and founding year, which is enough to filter down to a specific enterprise segment. The DNS-verified subset is the most reliable segment to filter on.
