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.
Maxim AI
Maxim AI is an evaluation and observability platform for teams building AI agents. Its prompt IDE lets teams try prompts, models, tools, and context, manage prompt versions, create low-code chains, and deploy prompts without code changes. Teams can simulate agents in varied scenarios and assess them with preset or custom metrics. In production, workflow traces, live debugging, online evaluations, and regression alerts help teams monitor agents. Evaluators include LLM-as-a-judge, statistical, programmatic, and human options; teams can use synthetic or custom multimodal datasets. Product managers can define and analyze evaluations in a no-code UI, while developers can use SDKs, a CLI, and webhooks. SDKs are listed for Python, TypeScript, Java, and Go. Maxim supports web, API, and self-hosted deployment, with enterprise VPC deployments available. The Developer plan is free; Professional costs $29/user/mo and a 14-day trial is available. The free plan has up to 3 seats, 1 workspace, 10k monthly logs, and 3-day data retention.
