HoneyHive

HoneyHive is an observability and evaluation platform built specifically for AI agents and LLM applications, aimed at the gap between a promising prototype and a system that holds up in production. It is OpenTelemetry native, so rather than replacing a team's existing stack it instruments every step of an agent run, the prompts, retrieval, tool calls, and model outputs, and turns that into distributed traces. The company positions itself as a DevOps stack for AI, with a single system of record that versions traces, prompts, tools, datasets, and evaluators for full auditability.

On the observability side, HoneyHive visualizes agentic workflows as graphs so teams can see where an error cascades across tool calls and reasoning steps, monitors cost, latency, and quality in production, and supports custom dashboards, alerts and drift detection, segment analysis, and user feedback capture. It logs synchronously or asynchronously through its SDK, and provides automatic instrumentation for more than fifty libraries including LangChain, LangGraph, AWS Strands, Google ADK, and the OpenAI Agents SDK. By default it does not proxy model requests; prompts are stored as configurations and fetched through an API.

Evaluation is the platform's other half and spans the full lifecycle. Teams run offline tests on large suites before deployment, compare versions, and catch regressions in CI through GitHub Actions, then evaluate live traffic online with sampling. HoneyHive ships dozens of prebuilt evaluators, lets teams write custom code or LLM evaluators in an evaluator console, and supports third party evaluators, covering checks like context relevance, answer faithfulness, tool use accuracy, and custom moderation filters. It pairs automated scoring with human evaluation through annotation queues and custom rubrics, and lets teams curate golden datasets from production or synthetic data, with critical failures escalated to humans for review.

HoneyHive keeps agent payloads isolated per tenant, sees only metadata and metrics rather than the payloads themselves, and is SOC 2 Type II, GDPR, and HIPAA compliant with third party penetration testing. The free Developer tier covers 10,000 events a month for up to five users with thirty day retention and the full observability and evaluation suite. The Enterprise tier, quoted on request, adds custom limits, unlimited users, SAML single sign on, custom roles, PII scrubbing, a business associate agreement, and hosting that ranges from single tenant SaaS to hybrid and fully self hosted.
