Pulzor
Read full descriptionHide full description
Monitor your websites, APIs and servers directly from your iPhone. Get alerted when things go down, understand what's happening and act immediately with real tools like SSH, automation and Auto-Recovery. No accounts, no external servers, no need for a computer. Pulzor is built on a simple idea: monitoring should give you visibility, context and the ability to respond, without compromising your privacy. Your data lives on your device and in your personal iCloud. It doesn't pass through third-party servers. It's yours. MONITOR WHAT MATTERS Pulzor monitors websites, endpoints, APIs, TCP ports, services, SSL certificates, domains and DNS. Check your infrastructure status in the background and get notified when it detects downtime, degradation or recovery. Includes HTTP, TCP and API monitoring with smart retries to reduce false alarms, complete SSL verification and advance warnings before certificates or domains expire. You can also watch multiple TCP services with preset profiles and custom ports. UNDERSTAND WHAT'S HAPPENING It's not just about telling you something failed. Pulzor helps you diagnose it. Each monitor gathers real-time status, event history, recent activity, response metrics, incidents, heatmaps and useful technical data to understand the real health of your service. The overall summary lets you see uptime, latency, activity, security alerts and trends in one view. So you know what happened, when it started, how it's evolving and where to look before you intervene. TAKE ACTION FROM YOUR IPHONE Pulzor doesn't just detect problems. It lets you respond to them. Includes an integrated SSH terminal to run remote commands, review logs, restart services, check processes, validate certificates or intervene on your infrastructure when something fails. You can also automate responses with Auto-Recovery and scheduled tasks, so certain issues resolve themselves even when you're not watching. It's monitoring with real action capability. ALERTS THAT MATTER Get downtime, degradation and recovery alerts instantly. Customize sounds, monitors and behavior for each notification. Track incidents in real time with Live Activities on your lock screen, widgets and Apple Watch. Pulzor is designed to alert you when it really matters, not to fill you with noise. DNS, SSL AND DOMAINS UNDER CONTROL Check DNS records, detect changes, validate important configurations and monitor SSL certificates and domains before they become a problem. If something changes in your public infrastructure, you'll know. REAL API MONITORING Pulzor doesn't stop at simply checking if APIs respond. You can monitor APIs with different HTTP methods, authentication, custom headers, body, validations and advanced checks to ensure the response is correct, not just that it exists. BEYOND THE PUBLIC Pulzor can also work with private services, internal networks and infrastructure that other external tools can't easily reach. When you need to check something beyond what's visible from the Internet, Pulzor is ready for it. ACROSS THE ENTIRE APPLE ECOSYSTEM iPhone, Apple Watch, widgets, Live Activities and Siri Shortcuts. All your infrastructure accessible from every important surface in the Apple ecosystem. PRIVATE BY DESIGN Privacy isn't an added feature. It's part of the product. No accounts. No tracking. No third-party SDKs. No external servers for your data. Credentials protected in Apple Keychain. Encrypted backups. No compromises. Pulzor gives you monitoring, alerts, diagnosis and real action from your iPhone, with the privacy your infrastructure deserves.
