ExpiryOwl VS WebPixie

ExpiryOwl's answer

Web agencies, freelancers and WordPress maintainers who look after many small client websites and need to know before a client's certificate or domain runs out.

WebPixie's answer:

WebPixie is built for website owners, SaaS teams, developers, digital agencies, e-commerce businesses, and technical teams managing one or multiple websites. It is particularly useful for teams that want to detect technical issues before they affect customers.

ExpiryOwl's answer

I looked after a client's site and found out about problems when the client told me. Certificate lifetimes are dropping (100 days from 15 March 2027, 47 days from 15 March 2029), so certificates renewed by hand will need replacing about four times a year, then about eight. I built ExpiryOwl so an agency sees every client's certificates and domains on one page and hears about a failed renewal before the client does. It is independently run, from Bahrain.

WebPixie's answer:

WebPixie was created around a simple observation: a website can remain online while many important problems develop quietly in the background. SSL certificates can expire, DNS records can change, domains can approach expiration, links can break, and website content can be modified unexpectedly. WebPixie was built to bring these signals together and make website monitoring more complete, understandable, and proactive.

WebPixie's answer:

WebPixie is currently growing its user base among website owners, SaaS teams, developers, and agencies.

ExpiryOwl's answer

Next.js, React and TypeScript, SQLite with Drizzle, a Node.js background worker for the checks, RDAP for domain data, Certificate Transparency logs for subdomain discovery, and Cloudflare in front.

WebPixie's answer:

WebPixie is primarily built with React on the frontend, Python and Node.js on the backend, and MongoDB as the database.

ExpiryOwl's answer

Many uptime monitors don't watch domain registration, so agencies pay for a second tool. ExpiryOwl covers certificates, domains, DNS and uptime in one plan, with white-label client reports and status pages included from the Agency plan ($29 a month for 250 domains), not sold per page. One price per agency: no per-check, per-page or per-client fees.

WebPixie's answer:

Choose WebPixie if you manage websites rather than servers: site owners, agencies and marketing or SEO-minded teams who want SSL, DNS, domain, link and crawlability checks together instead of separate tools. The free plan covers 3 websites and 5 uptime monitors with SSL, DNS (including DNSSEC), domain expiry and the Site Score, no credit card required. Paid plans add faster checks, Slack and webhook alerts, incident management, API access and team workspaces. If you mainly need many uptime monitors, very frequent checks, or ping, port and cron monitoring, dedicated uptime tools may fit you better.

ExpiryOwl's answer

One hostname, four checks, one tool: SSL certificate, domain registration, DNS and uptime, grouped by client. It also flags a Let's Encrypt, ZeroSSL or Google Trust Services certificate that is still being served after the point where it normally renews, usually weeks before it expires. For Let's Encrypt it reads the renewal window the CA publishes (ARI).

WebPixie's answer:

WebPixie is built around website health rather than just uptime. From one dashboard it combines uptime checks from multiple global locations, SSL certificate chain validation, DNS monitoring across 20+ record types including DNSSEC, domain expiry via WHOIS/RDAP, a link crawler, sitemap monitoring and an indexability checker (robots.txt, llms.txt, canonical checks), and rolls the results into a 0–100 WebPixie Site Score. There is nothing to install: add a domain and choose the checks you want. AI-supported analysis is used in selected features.
