Technical audit & JavaScript crawling
Multi-threaded crawling with real JavaScript rendering: your pages are explored the way an engine sees them, not the way the initial HTML describes them. PageSpeed, scheduled crawls, and diffs between two runs.
Ship apps that are fast, accessible, and cited by AI
Your pages are built in the browser, after the page loads. Most audit tools read the code the server sends, find an almost empty page, and conclude you have no content. We display the page first, then audit what an engine actually sees.
Access opens in waves: we email you when yours is ready.
Your pages crawled the way a browser renders them
01
Your client-side routes, genuinely crawled
JavaScript rendering is enabled per campaign: the crawler walks your views like a browser, not like a view-source window.
02
Core Web Vitals on the pages that matter
PageSpeed measurements collected inside the crawl and comparable run to run, which is what makes them usable for an engineering trade-off.
03
Accessibility measured on the rendered page
A rendered accessibility audit on every scheduled crawl, so regressions show up when they are introduced rather than six months later.
04
Stay findable while search changes
Answer engines are becoming an acquisition channel. We verify their crawlers can read your product, and capture whether you get cited.
How it starts
Three settings, and the crawl sees your app
JavaScript rendering is a per-campaign setting, not a per-site one: you decide where it is worth the cost.
-
01
Turn on JavaScript rendering
The crawler walks your views the way a browser renders them, down to routes the initial HTML never mentions.
-
02
Schedule the campaign
Every run is comparable to the last: a regression gets a date instead of a hunch.
-
03
Read accessibility and citations
Both are measured on the rendered page, in the same run, with no integration to write.
The modules a product team actually uses
A client-rendered app cannot be judged on its initial HTML. Every module starts from what a browser sees.
Accessibility: WCAG & RGAA
Rendered audits on every scheduled crawl, contrast cards with a suggested fix, screenshots of the failing elements, and an exportable conformance report.
- WCAG 2.2 AA reference
- RGAA 4.1 reference
AI visibility & GEO
Answer engines cite sources. We check which of their crawlers can actually read your site, validate your llms.txt, and capture your share of citations from real answers, with the denominator shown next to it.
- 19 AI crawlers audited measured
- 11 operators covered measured
Semantic optimisation & AI copilot
Per-page semantic coverage, keyword clustering by meaning rather than by string, E-E-A-T signals, and recommendations ranked by impact and effort.
- 5 finding blocks per page report measured
- 6 E-E-A-T signals counted per page measured
