Description by Masakatsu Aida Written by the developer, not by AppBrain. Click to read.
Register API endpoints, monitor HTTP status codes and JSON responses, and review recent failures from a clean dashboard designed for daily development and operations work.
API Signal supports GitHub authentication, making it easy for developers to sign in with an identity they already use. Your monitoring data is synced across web and mobile apps, so you can check endpoint status and failure history from the environment that fits your workflow.
The service is designed with a security-conscious and distributed architecture in mind. API checks, user access, logs, and notifications are handled through separated operational layers, helping keep monitoring stable and predictable as usage grows.
Key features:
GitHub sign-in for developer-friendly access
Cross-platform data sync across web and mobile apps
HTTP status monitoring for registered API endpoints
JSON response validation for practical API health checks
Failure logs focused on recent problems and debugging context
Notification support for operational awareness
API Signal is not just a simple uptime checker. It is a focused monitoring tool for developers who want to see API failures early, keep operational signals organized, and manage checks from multiple platforms without losing context.
