FAQ
What makes Waxell different from LangSmith, Langfuse, and other observability tools?
Waxell adds a governance layer that no other tool in the category provides. Every competitor on this page captures what agents did — Waxell also enforces what agents are allowed to do next, in real time, during execution. When a policy triggers, the agent receives structured feedback (retry, escalate, or halt) before proceeding. The difference is observability versus governance: recording versus controlling.
Does Waxell work with LangChain, LlamaIndex, and CrewAI?
Yes. Waxell auto-instruments 200+ libraries including LangChain, LlamaIndex, CrewAI, OpenAI, Anthropic, and most major vector databases and infrastructure tools. Initialize the SDK before your other imports and instrumentation begins automatically — no changes to agent logic required. Waxell is framework-agnostic by design.
Can I use Waxell alongside LangSmith or Langfuse?
Yes. Waxell can run alongside other observability tools. Some teams use Waxell for runtime governance and policy enforcement while keeping a secondary observability tool for evaluation or experiment tracking. Because Waxell instruments at the framework level, it doesn't conflict with proxy-level tools.
What governance policies does Waxell support?
Waxell supports eleven policy categories: Audit, Content, Control, Cost, Kill, LLM, Operations, Quality, Rate-Limit, Safety, and Scheduling. Each addresses a class of production risk — from runaway agent spend and prompt injection to unauthorized model access and silent failures. Policies are configured in the Waxell dashboard and enforced during execution, not reviewed after the fact.
How long does it take to add Waxell to an existing agent?
Two lines of code to initialize. Install the SDK with pip, set your API key, and initialize before your imports — instrumentation begins automatically. The full setup, including connecting your dashboard, takes under five minutes for most Python agent frameworks.
Is Waxell free?
Yes — Waxell is free during the beta period. It works with any Python agent framework and requires no credit card to start. Sign up at waxell.dev/signup.
