Core works with all major LLM providers including OpenAI, Anthropic, Google, Cohere, and any OpenAI-compatible API. Our SDK automatically detects and instruments LLM calls regardless of provider.

Our SDK is designed for minimal overhead. Tracing adds less than 5ms latency to requests, and we use async batching to avoid blocking your application. You can also configure sampling rates to reduce overhead in high-volume scenarios.

Absolutely. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). SOC 2 Type II is in progress, and Enterprise customers can choose to run in their own cloud or on-premise. We never train on your data.

Yes! We integrate with popular tools like Datadog, New Relic, Grafana, and more. You can also export data via our API or use webhooks to connect to any system.

Core is for developers who need to understand, debug, and optimize their AI agents. Surface is built on top of Core and adds features for agencies: automated verification, cryptographic proofs of work, and usage-based client billing.

Most teams are up and running in under 15 minutes. Our SDK initializes with a small snippet, and auto-instrumentation handles the rest without manual annotations.

Yes! The Developer plan is free and includes 100,000 traces per month. It's perfect for individual developers or early-stage teams. Upgrade when you need higher volume or advanced controls.

Enterprise customers can deploy Core on-premise or in their own cloud environment. Contact our sales team to discuss self-hosting options and requirements.
