Uptime & API monitoring

Monitor application and service availability using synthetic monitoring tools that simulate user requests from global checkpoints. Detect downtime, latency, or failed endpoints before they affect your users.

Simulate real user requests and interactions with your web pages from public or private locations to identify downtime and performance issues early.

Use synthetic monitoring to test internal APIs and web applications that are not accessible from the public internet. Deploy synthetic monitors within your private network to track performance from specific internal locations, and compare it with results from global public checkpoints.

Monitor complete user flows by simulating real interactions in the browser. Use synthetic browser monitoring to replicate multi-page journeys and perform key actions like clicks, form submissions, screenshots, and e-commerce transactions.

Integrate browser-based synthetic tests into your CI/CD pipeline to catch issues early. Validate login flows, checkout processes, and other business-critical journeys before deployment

SSL & Authentication manager

Keep your systems secure and accessible through SSL/TLS certificate monitoring and authority validation.

Use synthetic monitoring to validate SSL certificates to prevent downtime of APIs and websites by checking expiration dates daily. Detect changes every 10 minutes to get notified of unexpected changes that could cause security issues.

Monitor for any updates to your SSL certificates. Checks for certificate change every 10 minutes and alerts you on detecting any changes, with a detailed change report.

Checks for the expiration of the certificates every day and alerts you 28, 14, 7 and 3 days before the expiry.

Ensure authenticity by monitoring root and intermediate certificate authorities and get alerted if they differ from your expected certificate authority helping you avoid trust chain issues and potential attacks.

Status pages & incidents

Keep your users and teams informed with real-time status pages and incident updates.
Share planned maintenance windows, ongoing outages, and system health transparently using public or internal dashboards.

Website performance monitoring

Gain full visibility into your website’s performance across real devices and user scenarios with advanced synthetic web monitoring.

Measure key performance metrics like Largest Contentful Paint (LCP) and First Input Delay (FID) to ensure fast load times, better SEO, and a smoother user experience.

Analyze how your website would look and perform from the perspective of not just desktop users, but also mobile devices like iPhones and Galaxy phones, as well as tablets such as iPads and Kindle Fire devices.

Use synthetic monitoring with built-in authentication to track the performance and availability of password-protected pages and APIs. Keep sensitive services secure and operational.

Custom metrics & Advanced Monitoring

Monitor custom script speed, memory usage, and user actions by section for better website enhancements and enhanced user satisfaction:
  • Monitor custom script execution speed, memory usage, and user interactions by page section
  • Extract metrics from API responses to evaluate performance trends, track compliance, and improve UX.
  • Analyze your websites and APIs in pre-production, test, and live environments
  • Extract numbers from services you offer or third-party services you use to analyze trends and usage patterns

Proactive Alerting & Issue Detection

Anticipate issues before they escalate with real-time alerting and smart monitoring tools.

Proactively identify anomalies, critical incidents and address issues before they impact users using synthetic monitoring with instant notifications. Collaborate efficiently with your team to resolve issues faster and keep your services running smoothly.

Configure flexible alerting rules to monitor performance thresholds, availability, or error rates. Receive instant notifications via email, Slack, PagerDuty, or webhooks to respond before users are impacted.

Machine learning algorithms automatically detect unusual patterns, spikes, or behavioral anomalies. Get real-time alerts when unexpected activity is detected, enabling faster, smarter incident response.

Troubleshoot faster by viewing all related data, logs, metrics, events, and synthetic test results in one unified interface. Easily switch between sources or use split-screen mode for efficient root cause analysis.

Reduce noise and alert fatigue by correlating events and validating issues across multiple data sources. Focus only on real, actionable incidents not false alarms.

Collaborate effectively

Our platform fosters a culture of collaborative resolution, empowering your team to diagnose and fix issues faster, smarter, and together.

Invite team members to enable collaborative troubleshooting. Investigate and resolve faster together.

Quickly share reports via email with a single click, keeping stakeholders informed without direct access.

Control user access through flexible, fine-grained RBAC, ensuring data security and privacy across your teams.

We looked into running our own Elastic Stack, and quickly realized that was a job and specialty within itself. We are a small startup and every dollar counts. Wasting precious and expensive sysadmin time on managing things far out of our project scope really isn’t an option
