LightKeeper

What LightKeeper does

LightKeeper is a Portugal-based, founder-operated SaaS that performs Google Lighthouse-based website performance and SEO audits from up to 68 geographic regions, returning HTTP status codes, redirect chains, Core Web Vitals (LCP, TTFB, TBT, CLS), screenshots, rendered HTML, and failed-request diagnostics for each tested location. The product is positioned to address regional performance gaps that single-location speed tests miss, with explicit emphasis on SEO-specific diagnostics including canonical tags, hreflang annotations, and crawlable-link checks. It is operated as a self-employed sole proprietorship (Recibos Verdes) under Portuguese law by founder Denys Filchakov, who serves as sole creator, product engineer, and operator.

The underlying platform runs on a serverless architecture spanning AWS and GCP for the regional Lighthouse runners, Supabase for user authentication and report storage, Vercel for application hosting and Core Web Vitals monitoring, and Stripe for billing and VAT-compliant invoicing. Supporting tooling includes Sentry for error monitoring, MailerSend for transactional and marketing email, CookieYes for GDPR consent management, and Google Analytics 4 for consented behavioral analytics. The service is delivered exclusively through a self-serve web product with no sales team or channel partners.

The business model is a freemium SaaS: the free tier offers a shared global capacity of 10,000 test runs per hour with no credit card required, while premium subscription plans provide unlimited tests, priority processing, additional testing locations, advanced configuration, and dedicated support. Customer acquisition is product-led, relying on organic search, the LightKeeper blog covering technical SEO topics, and a free public checker accessible without signup, with the founder's LinkedIn presence serving as the primary social channel. The target users are SEO professionals, ecommerce and SaaS teams, and web developers who need to reproduce and share regional performance and indexing issues.

Broad incumbents

• Site24x7: Site24x7 (Zoho) is a broad digital performance monitoring platform offering synthetic website tests from global locations alongside APM, infrastructure, and log monitoring. It competes with LightKeeper on synthetic performance testing but as part of a much larger enterprise monitoring suite.
• Google PageSpeed Insights: Google's free PageSpeed Insights uses Lighthouse to test URL performance and Core Web Vitals. It is the default free tool that LightKeeper's free tier competes against, and as a Google property it sets the de facto standard for Lighthouse-based performance scoring worldwide.
• Pingdom: Pingdom (now part of SolarWinds) is an established website and uptime monitoring platform offering synthetic transaction and performance checks from global locations. It competes with LightKeeper in synthetic performance testing but operates as a broader, enterprise-grade monitoring suite.

Emerging players

• Treo: Treo is a website speed testing tool that runs audits from multiple global locations with Core Web Vitals focus. It targets a similar developer/SEO audience as LightKeeper and overlaps directly on the multi-region performance test use case.
• UptimeRobot: UptimeRobot provides synthetic uptime and basic performance monitoring from global locations. While more focused on availability than deep Lighthouse analysis, it competes with LightKeeper for SMB and developer customers seeking lightweight performance and uptime visibility.

Direct peers

• SpeedCurve: SpeedCurve provides synthetic and real-user performance monitoring with a strong focus on Core Web Vitals and design metrics for engineering and UX teams. It overlaps with LightKeeper on synthetic Lighthouse testing and competes for the same developer and performance-focused buyer persona.
• GTmetrix: GTmetrix is a website performance testing and monitoring tool explicitly named as a competitor to LightKeeper in the source data. It offers Lighthouse-based audits with global testing locations, paid premium plans, and a comparable buyer persona of developers, marketers, and SEO teams — a direct head-to-head competitor.
• DebugBear: DebugBear offers Lighthouse-based website speed monitoring, Core Web Vitals tracking, and synthetic testing focused on performance and SEO. Its overlap with LightKeeper in technology (Lighthouse) and audience (developers, SEO teams) makes it one of the closest feature-for-feature competitors.
• Calibre: Calibre is a SaaS for monitoring website performance, Core Web Vitals, and SEO at scale with synthetic testing from multiple regions. It targets developer teams and competes directly with LightKeeper on continuous regional performance monitoring and Lighthouse-driven reporting.
• WebPageTest: WebPageTest runs synthetic website performance tests from multiple global locations with detailed waterfall, Core Web Vitals, and filmstrip analysis. It targets the same developer/SEO buyer and serves as a free open-source-style reference point for regional performance testing.
