In the high-stakes world of web services, downtime isn't just an inconvenience—it's a business catastrophe. Every minute your servers are offline translates to lost revenue, frustrated customers, and damaged reputation. For years, companies have relied on proprietary monitoring solutions like UptimeRobot, PagerDuty, and Better Stack, accepting vendor lock-in and recurring subscription costs as necessary evils. But what if there was a better way? What if you could have enterprise-grade monitoring capabilities without sacrificing control, privacy, or your budget?

The Monitoring Landscape: Why CheckCle Matters
Traditional monitoring solutions operate on a simple but limiting principle: pay us monthly, and we'll watch your servers for you. While this model has worked for years, it comes with significant drawbacks that modern businesses can no longer ignore.
Consider UptimeRobot, one of the most popular monitoring services. Their free tier limits you to 50 monitors with 5-minute check intervals, while their paid plans start at $7/month for basic features. Scale up to enterprise needs, and you're looking at hundreds of dollars monthly for comprehensive monitoring across multiple services and locations.
PagerDuty takes this further, focusing on incident response with pricing that can easily reach thousands of dollars per month for larger teams. Better Stack offers modern features but maintains the same subscription-based model that keeps your monitoring data locked in their ecosystem.
What Makes CheckCle Different
CheckCle isn't just another monitoring tool—it's a complete paradigm shift toward monitoring sovereignty. Built with TypeScript and powered by PocketBase, this self-hosted solution delivers everything you'd expect from premium monitoring services, plus the freedom and flexibility that only open-source software can provide.
Complete Infrastructure Visibility
At its core, CheckCle provides comprehensive monitoring across every layer of your infrastructure:
- Multi-Protocol Support: Monitor HTTP, HTTPS, DNS, TCP, and ping protocols with precise accuracy
- SSL Certificate Tracking: Get advance warnings for certificate expiration with detailed issuer information
- Domain Monitoring: Never lose a valuable domain due to forgotten renewals
- Server Metrics: Track CPU, RAM, disk usage, and network activity with one-line agent installation supporting Linux (Debian, Ubuntu, CentOS, Red Hat) and Windows (Beta)
- Service-Specific Monitoring: Keep tabs on FTP, SMTP, databases, and any TCP-based services
Real-Time Alerting That Actually Works
CheckCle's notification system puts the big players to shame with its comprehensive channel support:
- Email & SMS: Traditional but reliable notification methods
- Modern Messaging: Slack, Discord, Telegram integration for team coordination
- Voice Calls: Critical alerts that demand immediate attention
- Webhooks: Custom integrations with your existing tools and workflows
Public Status Pages for Transparency
Nothing builds customer confidence like transparency during incidents. CheckCle includes full-featured status pages that rival StatusPage.io or Better Stack's offerings:
- Custom Branding: White-labeled pages with your logo and colors
- Incident Communication: Keep customers informed with real-time updates
- Historical Data: Show your reliability track record
- Mobile Optimization: Perfect viewing on any device
The Open-Source Advantage: Why It Matters
Cost Efficiency That Scales
Here's where CheckCle truly shines against commercial alternatives. While UptimeRobot charges $34/month for 100 monitors with basic features, CheckCle costs only what you pay for hosting—typically $5-20/month for a VPS that can handle thousands of monitors.
Consider the math: A company monitoring 500 services would pay UptimeRobot approximately $124/month. The same monitoring with CheckCle? Maybe $10/month in server costs. That's over $1,300 saved annually, with superior features and complete data ownership.
Privacy and Data Sovereignty
When you use SaaS monitoring solutions, you're essentially giving third parties complete visibility into your infrastructure topology, performance patterns, and downtime incidents. This data can reveal competitive advantages, operational weaknesses, and strategic business information.
CheckCle keeps everything local. Your monitoring data never leaves your infrastructure, ensuring complete privacy and compliance with data protection regulations. For organizations in regulated industries or those handling sensitive data, this isn't just a preference—it's a requirement.
Customization Without Limits
Proprietary solutions lock you into their feature set and roadmap. Need a specific integration? Wait for the vendor to prioritize it (if they ever do). Want custom alerting logic? Pay for expensive enterprise tiers or live without it.
CheckCle's open-source nature means unlimited customization potential. The TypeScript codebase is modern, well-structured, and actively maintained. Whether you need custom metrics, specialized alerting rules, or integration with proprietary systems, the source code is your gateway to infinite possibilities.
Technical Excellence That Delivers
Modern Architecture for Modern Needs
Built with TypeScript and powered by PocketBase, CheckCle represents the best of modern development practices:
- TypeScript Foundation: Type safety and excellent developer experience (98.6% TypeScript codebase)
- PocketBase Backend: Lightweight, fast, and incredibly reliable data layer
- Docker-First Design: Deploy anywhere with consistent, reproducible environments
- Multi-Location Monitoring: Verify incidents from multiple checkpoints to eliminate false positives
Performance That Outpaces the Competition
Where commercial solutions often struggle with scale and latency, CheckCle excels:
- Sub-Minute Monitoring: Check intervals as fast as 30 seconds for critical services
- Unlimited Monitors: Only limited by your server capacity, not arbitrary pricing tiers
- Fast Response Times: Local deployment means minimal latency in alerting
- Efficient Resource Usage: Modern architecture optimized for performance
Enterprise Features Without Enterprise Pricing
CheckCle delivers advanced capabilities that typically require expensive enterprise subscriptions:
- Multi-User Management: Team collaboration with role-based access control
- Maintenance Windows: Prevent false alerts during planned maintenance
- Incident Management: Full workflow support for incident response
- Advanced Analytics: Deep insights into performance trends and patterns
- API Access: Full programmatic control for automation and integration
- Multi-language Support: Localization options with dark & light themes
