Description
Open-source API development ecosystem. Test REST, GraphQL, WebSocket, and more — a lightweight Postman alternative.
No-Login Task
"Test and debug APIs"
Editorial Review & Verification
Hands-on VerifiedAPI developers, backend engineers, and QA testers testing REST, GraphQL, WebSocket, SSE, and gRPC endpoints without heavy desktop software or mandatory cloud logins
+ Key Strengths (Pros)
- ✓ Full-featured open-source Postman alternative requiring zero login for testing REST, GraphQL, WebSocket, and gRPC endpoints
- ✓ Generates executable client code snippets across cURL, Python, JavaScript, Go, and Ruby with one click
- ✓ Sends API requests directly from the client browser without routing sensitive tokens through third-party servers
− Limitations (Cons)
- − Browser-based requests to external APIs are subject to browser CORS policies unless using the Hoppscotch browser extension or proxy
- − Dispatches product analytics payloads to PostHog and loads the Crisp customer support chat widget
Deep Privacy & Sandbox Audit & Product Power & Utility Review
API requests execute directly from the client browser without passing request headers or authentication tokens through Hoppscotch proxy servers; telemetry includes PostHog analytics and Crisp chat connections.
Dispatched GET request to echo endpoint, rendered 1.96 KB formatted JSON payload in 1171 ms, and generated cURL snippet with 11 telemetry requests to PostHog and Crisp.
- ✓ Client-side processing is supported by catalog metadata and runtime evidence
- ✓ Bounded runtime observation found no payload egress; this is not architectural proof
- ✓ Runs locally without persistent server dependencies
- ✓ No commercial ad networks or cross-site tracking beacons
- ✓ Zero tracking pixels or third-party behavioral profiling scripts
- ✓ Clean script execution environment without user fingerprinting
- ✓ Publicly auditable code repository at https://github.com/hoppscotch/hoppscotch
- ✓ OSI-recognized open license: MIT
- ✓ 80,589 GitHub community stars
- ✓ Tool is online and accessible
- ✓ Monitored continuously by NoLoginTools automated prober
- ✓ No scheduled downtime or access gating detected

Fomrix STL Viewer is a free STL viewer online for opening and inspecting mesh geometry in the browser without an account. Rotate and zoom the model, inspect triangle counts and dimensions, and keep the original file unchanged. The viewer does not certify printability. This listing covers the independent STL viewer only; Fomrix AI model generation is separate and requires an account and credits.
