Inspect HTTP and HAR requests, test WebSocket and webhook flows, convert cURL, and check Helm, Kubernetes and container configuration.
Browse these tools ↓A failed request can originate in DNS, HTTP, browser policy, application behavior or deployment configuration. Start at the layer where you have evidence. A HAR file describes a recorded browser session; a live HTTP check describes a new request from the checking server, so their results can differ.
Inspect a captured HAR to see the original sequence. Use an HTTP header check for the current response and redirects, remembering that server-side checks cannot reproduce every browser CORS decision.
HAR Analyzer →Test the ws:// or wss:// endpoint, send a representative message, and inspect the response and close code. Keep authentication requirements and mixed-content restrictions in view.
WebSocket Tester →Render the Chart with the same values used for deployment. Inspect the final values and generated YAML before comparing environments or validating Kubernetes fields.
Helm Debugger →Record the hostname, method, status and exact error before changing configuration. Remove credentials from shared HAR files and request samples. Validate rendered deployment manifests after checking source templates, then confirm behavior in the target environment. Tool cards distinguish browser processing from backend checks; live connections contact their destination.
