Companies Using Inspectlet

I read Inspectlet detections the way a sales team would, asking what a hit says about the company behind the domain. As of our October 2026 crawl, TechnologyChecker.io finds Inspectlet on 5,694 live sites, and 3,479 of them match a company record, a 61.1% match rate. The short version: Inspectlet is a small, stable, older customer base, and almost every install is its own account.

What the signal catches

Our rule fires when a page creates Inspectlet's command queue (__insp), sets its loader flag, or loads a script from cdn.inspectlet.com. It's a clean test. On 30 random live domains, 24 of the 29 pages that loaded ran Inspectlet, one sat behind a bot check and four no longer loaded it. Our technology detection methods post explains how checks like this run in a browser.

Domains, accounts and fleets

Inspectlet puts a site ID in its script address, so we can count accounts as well as domains. On the 3,912 live domains where we could read it, we found 3,255 accounts, and 2,893 of them sit on a single domain. The largest covers 57 domains, a set of Australian self-storage sites. The title census turned up no parking or lander network: leaving aside pages whose title we couldn't read, the largest group of identical titles is 24 pages called "Home". Smaller clusters are one company's sites, such as a bookkeeping firm with 16.

Sales Signal: A list of Inspectlet domains is close to a list of accounts. Dedupe by root domain and you are talking to roughly one buyer per site, usually a founder or a marketing lead.

Growth trajectory

Our current crawl counts 4,760 Inspectlet sites in June 2026, 5,445 in July, 5,527 in August, 5,701 in September and 5,694 in October. Counts are not a like-for-like series over time: the set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals widen over time. The July step reflects changes on our side, both the domains we cover and the signals we detect Inspectlet with, rather than a surge in adoption. Since July the line is flat.

Exits are measurable. 946 domains have dropped Inspectlet since we began tracking it on 16 March 2026, 16.6% of the October count, and only 122 of them still load it on another hostname. Inspectlet's footer runs its copyright from 2011, and the age data fits a product that won its customers years ago: 45.83% were founded in the 2010s and only 11.57% in the 2020s.

"Inspectlet's base isn't shrinking fast, but it isn't being replenished either. Fewer than one in eight of its matched companies were founded this decade, the lowest share of any tool in its competitor table." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: Treat Inspectlet users as an installed base to win over, not a growth segment. These teams chose a recorder a while ago and may not have revisited it since.

The companies behind the domains

52.13% of matched companies with a size band have 1-10 employees and 79.97% have 50 or fewer. Only 53 have more than 1,000 staff. The named ones are a mixed group: the University of Texas at Austin on its OnRamps programme site, Shell Energy on its Australian business-energy pages, Manheim UK, Abu Dhabi National Insurance Company, Morocco's broadcaster SNRT and Penn Engineering's product catalogue. Universities stand out, with Universidad de Monterrey, Milwaukee School of Engineering and Leeds Arts University also on the list. Inspectlet's homepage quotes users' tweets rather than naming customer companies, so there's no vendor list to cross-check.

Sales Signal: At a large organisation, the Inspectlet owner is the team behind one site or programme. Start with that site's owner rather than central IT or marketing.

Industry and geographic concentration

Software Development (6.57%), IT Services (5.28%), Retail (4.93%) and Advertising Services (4.45%) lead, and the ten charted industries add up to only 36.8%. That is a horizontal base. Geography is more distinctive. The United States accounts for 1,347 of 3,479 matched companies (38.7%), with the United Kingdom (342), Australia (272) and India (204) next. India holds 5.9% of the matched base, more than twice its share on Hotjar's (2.3%) or Mouseflow's (2.5%) profiles, and Australia (7.8%) ranks third.

Sales Signal: For agencies and CRO consultancies in India and Australia, Inspectlet sites are a denser target list than their size suggests. Pair Inspectlet with country to find them.

Why there is no migration table

We tested switching corridors against every rival in the table and published none. Inspectlet usually shares the site with another recorder: Hotjar runs today on 593 Inspectlet domains (of 729 where we've ever seen both), Mouseflow on 90, Smartlook on 69, FullStory on 42 and Lucky Orange on 25. Every candidate corridor failed because most of those domains still run both. Recorders stack; a team tests one beside another, and the old tag stays.

"Session recorders pile up on a website. When 593 Inspectlet sites also run Hotjar, that's not a migration in progress, it's two tags nobody removed." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: A site running Inspectlet and Hotjar together is paying for, or at least loading, two recorders. Consolidation is the pitch, whichever side you sell.

Technology ecosystem

Google Analytics runs on 88.78% of the 5,650 domains in our stack analysis and Google Tag Manager on 87.31%. WordPress is on 39.4% and Elementor on 11.08%, with Shopify (9.98%) and WooCommerce (8.07%) well behind, so these are mostly lead-generation and content sites, not stores. Consent tools are scattered: CookieYes on 4.27%, Cookie Control on 2.42% and Cookiebot on 2.23%, and no consent tool reaches 5%. For a base that records visitor sessions, that's thin.

Sales Signal: Consent-management vendors should look here. A session recorder on a site with no visible consent tool is a compliance conversation, especially for the UK, Australian and Indian sites in this base.

Key takeaways

1. Inspectlet runs on 5,694 live sites, #13 of 34 in its category with a 0.34% share.
2. Installs are independent: 3,255 accounts across 3,912 readable domains, the largest covering 57.
3. The base is flat since July and older than its rivals', with 11.57% founded in the 2020s.
4. India and Australia are over-represented compared with Hotjar's and Mouseflow's profiles.
5. Hotjar runs alongside Inspectlet on 593 sites, so many of these teams already pay for, or test, a second recorder.

Sales applications

For targeting, filter Inspectlet on TechnologyChecker.io and keep companies founded before 2020 with 11-200 employees; that's the core of the paying base. For outreach to those running Hotjar too, an opener can be specific: "Your site loads both Inspectlet and Hotjar. Do you still need both recorders?" For competitive work, watch the 946 exits since March. Most are full removals, and a site that drops Inspectlet without adding a rival is still a prospect for whoever sells session replay next.
