Our verdict on psiLynx

psiLynx monitors website performance through scheduled Lighthouse audits across selected URLs, with mobile and desktop checks and available CrUX field data alongside lab measurements. It is aimed at developers, freelancers, agencies, and small teams tracking many pages. URL imports from sitemaps, CSV files, or pasted lists, plus grouping by page type or project, make it suited to site-wide monitoring rather than a single-page snapshot.

The plans scale mainly by weekly check volume, project and URL limits, history, and scheduling. Free provides 50 checks per week, one project with 30 URLs, 30-day history, and CSV and JSON export. Starter costs $19.99 per month for 150 weekly checks, three projects with 75 URLs each, 90-day history, and one scheduled check per project. Pro is $49.99 monthly, with 500 checks per week, 15 projects with 300 URLs each, 180-day history, three scheduled checks per project, and three team members. Business costs $129.99 per month and adds 2,000 weekly checks, unlimited projects and URLs, 365-day history, unlimited scheduled checks, custom cron schedules, and priority email support.

Its strongest fit is ongoing comparison: page-level history and run comparisons help identify regressions, while shareable and exportable reports make results easier to communicate. Email alerts are available, and the cloud product is web-based. CrUX adds real-user context for LCP, INP, and CLS when Google's traffic thresholds are met; otherwise the monitoring emphasis is on synthetic Lighthouse measurements. Choose psiLynx if scheduled URL coverage and history matter more than a broad alert-channel choice. Teams that require field data for every URL or non-email alerts should consider alternatives.
