httpclient.de
httpclient.de is an ad-free, lightweight utility designed for developers and sysadmins to inspect HTTP endpoints, REST APIs, and webhooks directly in their browser. It requires no user registration, stores zero request payload history, and sets no third-party tracking pixels.
Key Features & Capabilities
- Full support for all standard HTTP verbs (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS)
- Granular latency telemetry: TTFB (Time to First Byte), DNS lookup, and TLS handshake timing
- Real-time formatting and syntax highlighting for JSON, XML, and multipart payloads
- Instant one-click command export to cURL, JavaScript fetch, and Python requests
- Zero-retention architecture: API tokens and payloads never touch persistent server disks
