# FiddlerSpanProcessor

`FiddlerSpanProcessor` is a backwards-compatible alias for [`StrandsSpanProcessor`](/sdk-api/strands/strands-span-processor). They reference the same class -- `StrandsSpanProcessor` is the canonical name and `FiddlerSpanProcessor` remains exported so existing code continues to work.

```python theme={null}
from fiddler_strandsagents import FiddlerSpanProcessor, StrandsSpanProcessor

assert FiddlerSpanProcessor is StrandsSpanProcessor  # True
```

For the full reference, see [StrandsSpanProcessor](/sdk-api/strands/strands-span-processor).

> **Recommendation:** new code should import `StrandsSpanProcessor` directly.
