# Overview FAQ

Quick answers for first-time visitors. The full support FAQ lives in [Support](/12.-support/faq.md).

## "Is this a benchmark site or a tool?"

Both, on purpose. The public catalog (`stratix.layerlens.ai`) is the largest open browsable model leaderboard. The Premium workspace (`stratix.layerlens.ai`) is where you run your own evaluations on your own data. They're two doors into the same platform.

## "Do you compete with LangSmith / Braintrust?"

Yes, on the workspace side — see [How Stratix compares](/1.-introduction/how-stratix-compares-deep.md). On the public catalog and quarterly research side, no — none of the alternatives operate one.

## "Is the public catalog free forever?"

Yes. No signup. No rate limits beyond per-IP courtesy throttling.

## "Can I self-host?"

Enterprise tier supports (data plane in your VPC). Not OSS / fully self-hosted.

## "Why no TypeScript SDK yet?"

## "Is this for chatbots only?"

No. Stratix evaluates anything an LLM does — chat, agents, RAG, structured output, code, tool-use. Agents specifically get the [Agentic Evaluations](/4.1-general-use-cases/agentic-evals-overview.md) product.

## "Do I need to send my prompts to LayerLens?"

To run a private evaluation on your data, yes — within your tenant. BAA is available on Enterprise; for current compliance posture contact <security@layerlens.ai>. See [Security](/12.-support/12-support.md).

## "What does it cost?"

Free + Premium pay-as-you-go on ECU + custom Enterprise. Public is free always. See [Pricing](/12.-support/12-support.md).
