Most LLM observability tools feel like a tax on your growth.
As your traffic scales, your bill explodes. You're forced to choose between visibility into your RAG pipelines and keeping your margins. To make it worse, you're stuck wrapping your core logic in proprietary SDKs that create massive vendor lock-in.
Paying $500+/mo just to see which step in your RAG pipeline is slow? That's not observability — it's overhead.
Why rewrite your codebase every time you try a new tool? You should own your instrumentation.
Your traces are your most valuable debugging asset. They shouldn't be trapped in a black box you can't export.
Go from zero to production traces in under 60 seconds.

OPENAI_BASE_URL=http://localhost:4999/openaiPoint your LLM provider base URL to your TraceLayer instance. Nothing else changes.
open http://localhost:4999/uiInstantly see traces, costs, token usage, and agent loops in a local-first UI.
No code changes required. Works with OpenAI, Anthropic, LiteLLM, and any OTel-compatible provider.
Everything you need. Nothing you don't.
Industry-standard OpenTelemetry. If you ever leave TraceLayer, your instrumentation stays with you.
Debug locally for free with a blazing-fast UI. Promote traces to the cloud only when you need team collaboration.
Run TraceLayer entirely in your VPC. We never see your prompts, your keys, or your customer data.
Visualize complex agentic loops, tool calls, and RAG retrieval steps in a clean, interactive DAG.
Track spend by user, team, or feature tag. Know exactly where your OpenAI credits are going.
Export traces to CSV (with per-tag columns), JSON, or a local SQLite file. One click, no vendor lock-in.
Because we know you're building at 2 AM.
Set a cron schedule for automatic SQLite backups. Your data, your schedule, your infrastructure.
Simple. Transparent. Predictable.
