PageLantern vs Signalog
Both stand on api monitoring tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose PageLantern if you need externally configured monitoring across websites, APIs, DNS, or scheduled jobs, with alert channels and hosted status pages. Look elsewhere if your selection requires independently audited security certifications: PageLantern says it has none of SOC 2, ISO 27001, HIPAA, PCI DSS, FedRAMP, or similar certifications.

Choose Signalog if you want monitoring, incident coordination, paging, and status pages together, with integrations for alert delivery and event ingestion. Free is a useful entry point for up to five monitors, while teams needing more monitors, status pages, regions, or shorter checks can consider the paid plans. Teams requiring SSO/SAML 2.0 need Business.
