# Trace Imports

Mastra platform now supports trace imports, pulling existing traces from third-party observability providers into Mastra so they sit alongside Mastra-generated traces for debugging, filtering and comparison. Previously Mastra observability data could only be exported to third-party providers, so switching vendors often meant leaving trace history behind. Langfuse is supported first, with more providers to follow; imports preserve span types such as agent_run, model_generation and tool_call, along with parent-child structure, timestamps, inputs, outputs, usage and cost, while scores, feedback, datasets, attachments and logs are omitted.
