Integration guides

Practical walkthroughs for debugging specific libraries and frameworks with Smello. Each guide shows a real scenario, the setup needed, and what you'll see in the dashboard.

The dashboard always projects runtime parent-child relationships and can add one virtual grouping by pytest collection level or remote host. Run the local hierarchy_demo.py to see groups inserted where memberships begin within the runtime tree.

Test frameworks

Smello's bundled pytest plugin records every test function or method invocation as a separate event.

• Debug pytest tests: inspect parametrized cases, fixtures, timings, and failures

Outgoing HTTP (auto-patched)

These libraries are monkey-patched automatically when you use smello run.

• Debug requests: inspect headers, bodies, and redirects
• Debug httpx: async and sync HTTP debugging
• Debug aiohttp: async HTTP client debugging
• Debug gRPC: see protobuf payloads as JSON
• Debug boto3 / AWS: AWS API calls and XML responses
• Debug Google Cloud: BigQuery, Firestore, Pub/Sub via gRPC

SDKs that use patched libraries under the hood

These SDKs use httpx or requests internally, so Smello captures their traffic automatically.

• Debug OpenAI: see raw API calls behind the SDK
• Debug Anthropic: inspect Claude API requests
• Debug Gemini: inspect GenerateContent requests and function calls
• Debug Stripe: webhook debugging and API call inspection

Server frameworks (middleware)

Explicit middleware for capturing incoming HTTP requests.

• Debug FastAPI: incoming request inspection and exception capture
• Debug Django: incoming request inspection and exception capture
