Open-source, OTel-native observability for autonomous AI agents. Full telemetry, cost tracking, and safety alerts — on your machine, no backend required.
TokenJam is a CLI-based observability tool for developers building agentic AI systems. It gives you full visibility into what your agents do — tool calls, token costs, behavioral drift, and sensitive actions — without requiring a SaaS account or cloud dependency.
Key features:
- OTel GenAI Semantic Conventions compliance (exportable to Grafana, Jaeger, Datadog)
- Real-time USD cost tracking per agent, per model, per task
- Sensitive action alerts (email sends, file writes, form submissions)
- Local behavioral drift detection
- Output schema validation
- Full-featured CLI + local REST API
Works with: OpenClaw, LangChain, LangGraph, CrewAI, AutoGen, OpenAI Assistants, Anthropic Claude, and custom agents.
TokenJam is in active development. This repo currently hosts the landing page at tokenjam.dev. The CLI tool is coming soon.
