In their own words
Braintrust
Braintrust is an observability platform for teams running AI agents in production. It lets teams inspect agent traces and tool calls while tracking latency, cost, and quality in real time. Users can evaluate datasets, compare prompts and models, and score outputs with LLMs, code, or human reviewers. Discovery tools surface patterns in production traces to help investigate agent behavior, and the Loop agent can run evaluations, generate test cases, and iterate on prompts autonomously. Braintrust lists native SDKs for Python, TypeScript, Go, Ruby, C#, and more, and its MCP server lets coding agents query logs, run evaluations, and update prompts from an IDE. Security options listed include SSO, RBAC, and hybrid deployment; Braintrust states that it is SOC 2 Type II certified and GDPR and HIPAA compliant. Starter is free, with 1 GB processed data, 10,000 scores, and 14-day retention. Pro costs $249.00 per month; Enterprise pricing is custom.
HoneyHive
HoneyHive is an agent observability platform for observing, evaluating, and improving AI agents in production. It captures traces that expose tool calls, prompts, and agent decisions step by step. Teams can run automated code-based checks, LLM-judge evaluations, and human reviews through annotation queues and custom rubrics. Live traffic monitoring supports score thresholds, drift detection, and email or webhook alerts, while experiments compare agent versions on datasets and track regressions before release. Integrations include LangChain, LangGraph, CrewAI, OpenAI Agents SDK, and Microsoft Copilot Studio. Tracing follows OpenTelemetry semantic conventions, allowing OTel-instrumented libraries to send data without a dedicated guide. HoneyHive also provides cost and token-cost tracking, prompt management, and tracing for LLMs, agents, and retrieval. The free Developer plan costs nothing and includes five users, one workspace, unlimited projects, 10,000 events monthly, 30-day retention, and 1,000 requests per minute. Enterprise has custom pricing and hosting options.
