Maxim AI is an evaluation and observability platform for simulating, assessing, and monitoring AI agents.
What Maxim AI is
Maxim AI is an evaluation and observability platform for simulating, assessing, and monitoring AI agents. Its prompt IDE lets teams try prompts, models, tools, and context, keep versions, build low-code prompt chains, and deploy prompts without code changes. Teams can simulate agents in varied scenarios and evaluate them with predefined or custom metrics. For production, the platform provides workflow traces, live issue debugging, online evaluations, and regression alerts. Evaluation options include LLM-as-a-judge, statistical, programmatic, and human evaluators, with synthetic or custom multimodal datasets. Product and engineering teams can use a no-code evaluation workflow, SDKs, a CLI, and webhooks; SDKs are listed for Python, TypeScript, Java, and Go. Integrations include LangChain, OpenAI, Anthropic, Bedrock, and Mistral. Maxim is available on the web, through an API, and as self-hosted software. Its free Developer plan has up to three seats, one workspace, 10,000 monthly logs, and three-day data retention. Professional costs $29/user/mo, and a 14-day trial is available. Enterprise options include VPC deployments and custom SSO.
