Built for teams shipping AI to production
19.2x Plan Value
Surface hidden token value. We show you exactly how much you save vs raw model costs.
Local-First
No cloud, no data leaks. 100% local observability for Cursor, Claude Code, and your stack.
Superior Coverage
First-class support for Groq (500 t/s), Ollama, and Mistral. Blazing fast inference tracking.
Semantic Drift
Detect when model responses deviate from ground truth. Stop hallucinations before users see them.
PII Redaction
Automatic detection and masking of sensitive information before it hits model providers.
Prompt Debugger
Visual replay of agent reasoning chains and tool invocations for rapid debugging.
Watch your models think
Capture every interaction across your AI stack. From raw prompts to structured outputs, LLM Observer provides real-time visibility into the "black box" of model inference.
Prompt Debugging
Step through reasoning chains and tool calls with full context.
PII Redaction
Identify and mask sensitive data using production-grade guards.
Semantic Trend Mapping
Cluster sessions by intent to monitor topic drift over time.
Scale with confidence
Transparent pricing for teams of all sizes.
Starter
Perfect for side projects and local experimentation.
Pro
Advanced observability for scaling products.
Enterprise
Security & compliance for high-volume teams.
