Mastra adds trace imports from Langfuse to pull observability history into its platform
Mastra introduced trace imports for Mastra Platform, letting users pull existing traces from third-party observability providers into Mastra, where they appear alongside Mastra-generated traces for debugging, filtering and comparison. Langfuse is supported first, with more providers to follow; Mastra notes that observability data previously could only be exported out to third parties. 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. The CLI requires [email protected] and @mastra/[email protected] or later and supports dry-run previews, date windows with --since/--until, and resuming interrupted imports.
It lowers the switching cost away from rival observability tools by letting teams keep their existing trace history.
