This page is designed to help you find out whether Apogee Watcher is good and if it is the right choice for you.
Apogee Watcher is a multi-tenant PageSpeed monitoring platform built for digital agencies, freelance developers, and in-house teams who manage multiple websites. It automates performance testing using Google PageSpeed Insights, tracks Core Web Vitals across your entire portfolio, and delivers alerts and client-ready reports from a single dashboard—without manual work, per-site juggling, or the engineering overhead of DIY Lighthouse CI setups.
Add your websites and Watcher discovers pages from sitemaps and HTML crawl—no manual URL entry for hundreds of URLs. Tests run on a schedule (daily, weekly, or custom per site). Every test returns lab metrics (Lighthouse) and real-user field data (CrUX) when available: LCP, INP, CLS, FCP, TBT, Speed Index, and performance scores, with full historical tracking so you can spot trends, not just snapshots. Mobile and desktop are tested separately.
Set performance budgets (e.g., LCP ≤ 2.5 seconds, CLS ≤ 0.1) and receive alerts when metrics exceed thresholds. Smart cooldowns prevent notification spam. Generate white-label PDF reports for clients with your logo and branding. Manage multiple organisations and sites from one login with Admin, Manager, or Viewer roles. No API key management; no CI maintenance; no juggling separate accounts per client. True organisation-level separation—competitors like GTmetrix and DebugBear use flat project lists; Watcher was designed for agency workflows from day one.

Primary: Agency technical leads who manage 10–50+ client sites, need automated monitoring and client-facing reports, and search for terms like "pagespeed monitoring for agencies", "automated core web vitals", and "client performance reports".
Secondary: Freelance developers and consultants managing 1–10 client sites who want affordable, hands-off monitoring.
Tertiary: In-house SEO and marketing teams who own website performance as part of SEO and need to report Core Web Vitals to leadership.
Apogee Watcher was built by Apogee Information Systems (est. 2002) to solve the fragmented monitoring problem: manual PageSpeed checks don't scale, per-site tools get expensive, Lighthouse CI becomes a maintenance burden ("monitoring felt like a full-time job"), and agencies lack a clean multi-tenant dashboard and client-ready reporting. Watcher was built for agencies with 10–50+ sites from day one, at agency-friendly pricing. No VC pressure—we build for the long term.
Apogee Watcher is pre-launch or early stage and is currently being used internally for Apogee's clients.
