Lighthouse CI runs when you deploy. Uptime monitors watch one endpoint. SEO crawlers hand you a snapshot. Here is exactly where Fortely fits — and where it does not.
Your uptime monitor knows the homepage responded. Your CI knows the three URLs in its config scored well at the moment you merged. Your SEO crawler knows what the site looked like the last time someone remembered to run it. None of them know that a CMS edit dropped the canonical tag on forty product pages last Thursday.
Fortely is built for that gap: the whole site, every discipline, on a schedule, with each scan compared against the last one.

Categories, not specific products — capabilities vary between tools within each column. If your tool does more than we credit it for, tell us and we will correct this table.
Performance, SEO, accessibility, security, and availability are usually four separate tools with four separate dashboards. Fortely runs all 94 checks in a single scheduled crawl and reports them in one place, against one timeline.
A static score tells you your site has always been a 78. Every Fortely scan is diffed against your last baseline, so the alert says "LCP regressed on 12 pages since Tuesday" — not "your performance score is 78".
Plenty breaks without a deploy: a CMS edit strips a canonical tag, a third-party script starts throwing, a certificate lapses, a robots.txt change blocks the crawler. CI never runs for any of those. Fortely does.
