Details

Glassbrain is a developer debugging tool that captures every execution step of an AI application as an interactive visual trace tree.

Key features are as follows:

  • Interactive replay: You can click a specific node to change inputs, or instantly replay the execution process without redeploying.
  • Two modes: Supports snapshot mode for deterministic replay and live mode using the actual stack.
  • Auto-fix and comparison: Provides auto-fix suggestions based on trace data, and lets you clearly check changes through a Diff view.
  • Collaboration features: Generates shareable replay links so you can debug together with team members.

It is compatible with OpenAI and Anthropic, and can be integrated with just two lines of code. The free tier provides 1,000 traces per month.
