Maxim AI review
A broad evaluation workflow with a free plan and $29-per-seat Professional tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Maxim AI is an evaluation and observability platform for teams building AI agents and applications. It covers prompt experimentation and comparison, prompt versioning and deployment, agent simulations, automated and human evaluations, production observability, datasets, and CI/CD evaluation automation. Product and engineering teams can work through a no-code interface, SDKs, and APIs across web, API, and self-hosted deployments.
Its plan structure suits teams that want to start small and expand their evaluation workflow. The free Developer plan includes up to 3 seats, 1 workspace, up to 10k logs per month, 3-day data retention, and email support. The 14-day trial applies to Professional and Business. Professional costs $29 per seat per month and adds unlimited seats, up to 3 workspaces, up to 100k logs monthly, 7-day retention, simulation runs, and online evaluations. Business costs $49 per seat per month and adds unlimited workspaces, up to 500k logs monthly, 30-day retention, RBAC support, PII management, and scheduled runs. Enterprise adds custom SSO, in-VPC deployments, custom limits, custom retention, audit logs, custom SLAs, and infosec reviews.
The main strength is breadth across the AI application lifecycle rather than a narrow focus on one evaluation method. Teams can combine pre-built and custom evaluators, LLM-as-a-judge evaluation, human review workflows, custom metrics, datasets, and production monitoring. Integrations include OpenAI, Anthropic, Google Gemini, Mistral, LiteLLM, LangGraph, LangChain, CrewAI, OpenAI Agents, LiveKit, and Agno. Maxim AI fits teams that need connected experimentation, evaluation, and observability workflows at a measured starting cost. Teams needing longer retention on the free plan, or fixed Enterprise pricing, should compare alternatives.
