whyLLM — Every LLM call, traced and controlled

Karan Singh

Karan Singh

Real-time visibility into every LLM call, every why is answered without touching a single line of your existing code.

Pick your path. Working in 2 minutes.

Four ways in — from two lines of code to zero file changes. Every call captured automatically from the first request.
The problem

Right now, you're flying blind

Every day without observability is money you can't recover and quality issues you can't explain.
What you get

Three things no other tool does well together

Every LLM call captured — prompt, response, model, token count, latency. Filter by user, feature, or environment. Search your entire history in milliseconds.
Not just dashboards — actual enforcement. Set budgets per project, user, or API key. Auto-route to a cheaper model when a threshold hits. Kill switches included.
Fast heuristics score every response for confidence, factual consistency, and refusal patterns. LLM-as-judge only fires on flagged spans — keeps cost near zero.

Simple. Usage-based. No per-seat nonsense.

Pay for what you trace. A 10-person team shouldn't cost 10×.
Free forever — no credit card required
The engineers who wait find out about problems from their users. The ones who ship win.

Observability for the LLM call you can't see. No code 2 line change captures every prompt, response, token split, cost, and hallucination across every provider.
