AgentFlight: AI Agent Observability & Flight Recorder (TypeScript)
Preview and demo
Status: unchecked. Availability checks are not a security guarantee.
Description
AgentFlight is a framework-agnostic flight recorder and observability layer for AI agents.
The Problem: Debugging AI agents is hard. You can't see which step failed, how many tokens were consumed, or where the costs are coming from.
The Solution: AgentFlight automatically records every step (LLM calls, tool usage, errors) of your AI agent, calculates token usage and estimated costs, and provides a CLI to inspect the flights.
Key Features:
- One-line integration with OpenAI SDK and Vercel AI SDK.
- Automatic token counting and cost estimation per step.
- Streaming support (captures token usage even in streams).
- Lightweight CLI: agentflight list and agentflight show <id>.
- JSONL storage by default (easy to extend to Postgres or others).
Tech Stack: Node.js, TypeScript.
Installation: npm install @berkayyn/agentflight
Important: Please ensure you are installing the correct package @berkayyn/agentflight (not the unrelated agentflight package on npm).
