Beyond print(): An Open-Source Local Debugger for AI Agents
No_Firefighter8428 · reddit · 2026-08-10
A developer built a local debugger for AI agents after getting frustrated with using print() statements.
The tool allows developers to inspect runtime details, including:
- Prompts & Memory: View full prompts and retrieval context.
- Tool Calls: Monitor external tools and parameters invoked by the agent.
- Replay & Compare: Replay execution traces and compare good vs. bad runs for easier debugging.
The project natively supports LangChain and includes a free Groq demo. The author is actively updating it daily and seeks feedback from developers building production agents.
