As answered by people managing DevTools Advanced and TraceAgently.
TraceAgently's answer:

TraceAgently's answer:
Most observability tools wrap your LLM calls. TraceAgently works with any agent loop you write yourself, not just supported frameworks. You instrument what matters and see it live.
TraceAgently's answer:
No framework lock-in, no SDK wrapping your entire stack. Works in 5 minutes and has a genuinely free tier.
