Free plans check every 5 minutes. Starter plans check every 1 minute. Growth and Pro plans check every 30 seconds. Scale plans check every 15 seconds. Heartbeat monitors support fixed intervals or custom cron expressions (up to 5-field format). All plans include multi-region validation from US, Canada, Europe, and APAC." } }, { "@type": "Question", "name": "What monitor types are available on each plan?", "acceptedAnswer": { "@type": "Answer", "text": "Free and Starter plans include HTTP and Ping monitors. Growth, Pro, and Scale plans unlock all eight types: HTTP, Ping, SSL, DNS, Domain Expiry, Keyword/Content, Port monitoring, and Heartbeat/Cron monitoring with full protocol validation." } }, { "@type": "Question", "name": "How does multi-region monitoring work?", "acceptedAnswer": { "@type": "Answer", "text": "Every check runs from probes in four regions: US, Canada, Europe, and APAC. Results are validated against geographic constraints and aggregated using a quorum-based consensus policy (e.g., majority voting). This eliminates false positives caused by regional network issues — a single region going down won't falsely alert your team." } }, { "@type": "Question", "name": "What notification channels are available?", "acceptedAnswer": { "@type": "Answer", "text": "FourSight supports four notification channels: Email (rich HTML templates), Slack (Block Kit formatting with status emojis and deep-link buttons), Webhooks (JSON payloads with optional HMAC-SHA256 signing and exponential backoff retries), and SMS (via E.164 phone numbers with carrier-compliant opt-in). You can configure rules per monitor and severity level." } }, { "@type": "Question", "name": "How do alerts and incidents work?", "acceptedAnswer": { "@type": "Answer", "text": "When a check fails across enough regions to meet quorum consensus, FourSight automatically creates an incident with a severity level (critical, major, or minor) and sends alerts to your configured notification channels. The incident timeline tracks every status change — investigating, identified, monitoring, resolved — with timestamps. Recovery alerts are sent when the issue is resolved." } }, { "@type": "Question", "name": "What are maintenance windows?", "acceptedAnswer": { "@type": "Answer", "text": "Maintenance windows let you schedule planned downtime to suppress alerts and incident creation. You can create one-time windows or recurring schedules (daily, weekly, monthly) using RRULE patterns. Maintenance can target specific monitors or entire status pages, and active windows are visually indicated across the dashboard and public status pages." } }, { "@type": "Question", "name": "Do you have public status pages?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Every plan includes at least one public status page. Starter includes 2, Growth includes 5, Pro includes 10, and Scale includes 25. Pro and Scale plans support custom CSS for full brand matching." } }, { "@type": "Question", "name": "Do you support teams / multiple organizations?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. All plans support organizations with role-based access (owner, admin, member). Each organization has its own monitors, status pages, notification rules, maintenance windows, and billing." } }, { "@type": "Question", "name": "Can I see historical uptime and incidents?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Free plans retain 24 hours of history. Starter plans retain 14 days. Growth plans retain 30 days. Pro plans retain 90 days. Scale plans retain 1 year. Latency charts support per-monitor trends and regional breakdowns." } }, { "@type": "Question", "name": "How is pricing structured?", "acceptedAnswer": { "@type": "Answer", "text": "Plans are flat-rate based on monitor count: Free (10 monitors, $0), Starter (50 monitors, $16/month), Growth (100 monitors, $40/month), Pro (250 monitors, $80/month), Scale (500+ monitors, $160/month). No per-monitor charges or hidden fees. The Free plan is permanent — no credit card, no trial expiration." } }, { "@type": "Question", "name": "Can I pause monitors?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. You can pause any monitor temporarily without deleting it. Paused monitors don't run checks. Resume them anytime with a single click." } }, { "@type": "Question", "name": "What is port monitoring?", "acceptedAnswer": { "@type": "Answer", "text": "Port monitoring lets you check TCP or UDP ports on any host. It supports three validation modes: connect-only (just verify the port is open), banner check (read the initial response), and send/expect (send a string and match the response with regex). Presets are available for common services like SMTP (25), POP3 (110), IMAP (143), IMAPS (993), FTP (21), SSH (22), and DNS (53)." } }, { "@type": "Question", "name": "What is heartbeat monitoring?", "acceptedAnswer": { "@type": "Answer", "text": "Heartbeat monitoring (also called cron or script monitoring) tracks recurring signals from background jobs, scheduled tasks, APIs, webhooks, or any external service. You set an expected interval or cron schedule, and FourSight alerts you if a ping is missed or arrives outside your grace window. Perfect for batch processes, cleanup jobs, and health check endpoints that must run on schedule." } }, { "@type": "Question", "name": "Can I use the free plan for my business?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. FourSight's free plan explicitly allows commercial use — monitor client sites, production apps, and revenue-generating services. You get 10 monitors with 4-region consensus, email alerts, and a status page, permanently free with no credit card. (Several competitors restricted commercial use on their free tiers in 2025; FourSight has not and will state it plainly if that ever changes.)" } }, { "@type": "Question", "name": "Can I import monitors from UptimeRobot or Freshping?", "acceptedAnswer": { "@type": "Answer", "text": "There's no one-click importer yet — you re-create monitors in FourSight, which most teams find takes under 15 minutes for 20 monitors since each monitor is just a URL/host plus a check type. Step-by-step walkthroughs: see the Migrate from UptimeRobot and Migrate from Freshping guides. A bulk import tool is under consideration." } } ], "speakable": { "@type": "SpeakableSpecification", "cssSelector": [ ".faq-answer" ] } }, { "@context": "https://schema.org", "@type": "BreadcrumbList", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://foursight.cloud/" }, { "@type": "ListItem", "position": 2, "name": "FAQ", "item": "https://foursight.cloud/faq" } ] } ] --- [FourSight ](/) [Features](/#features)[Pricing](/pricing)[Guides](/guides)[Glossary](/glossary)[FAQ](/faq) [Login](/auth)[Start free](/auth?signup=true) [Start free](/auth?signup=true) # Frequently Asked Questions Everything you need to know about FourSight monitoring. FourSight is a multi-region website and infrastructure monitoring platform built for SaaS teams, agencies, and solo founders who need reliable uptime checks without the false-positive noise that single-region monitors create. Every check runs from probes in the United States, Canada, Europe, and Asia-Pacific, and results are aggregated using a quorum consensus policy before an incident is opened — so a transient network hiccup in one region never wakes your on-call. The platform covers eight monitor types: HTTP/HTTPS uptime, keyword and content presence, DNS records, SSL certificate expiry and chain validation, domain expiry via RDAP, TCP ping latency and packet loss, generic TCP/UDP port monitoring with banner and send/expect checks, and heartbeat (cron) monitoring for background jobs, scheduled tasks, and webhooks. Each monitor type ships with sensible defaults and presets for common services like SMTP, IMAP, IMAPS, FTP, SSH, and DNS, so you can configure a production-grade check in under a minute. When something does break, FourSight automatically opens an incident with a severity level, tracks every status transition on a timeline (investigating → identified → monitoring → resolved), and fans alerts out across email, Slack, signed webhooks, and SMS based on the notification rules you configure. Maintenance windows suppress alerts on planned downtime using one-time or RRULE-based recurring schedules, and public status pages — included on every plan — keep customers informed without exposing internal detail. Pricing is flat-rate by monitor count, starts at $0 for 10 monitors on the permanent Free plan, and tops out at $160/month for 500+ monitors on Scale. There are no per-check fees, no per-seat charges, and no trial expiration.
