Arize AX vs VoltOps

Arize AX is a platform for improving AI agents by turning production behavior into investigations, evaluations, and experiments. Signal surfaces important issues, helps identify causes, and prepares fixes for review. Managed Agents can investigate failing traces, fix repository bugs, automate recurring checks, or be created from scratch. Swarm Observability tracks status and performance across an agent swarm in real time. Agent-as-a-Judge uses telemetry to produce scalable evaluations that can surface unknown failures, while end-to-end experiments help validate changes. Integrations include OpenAI, Anthropic, Google GenAI, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and Vercel AI SDK; tracing follows OpenInference conventions and OpenTelemetry. AX Free costs nothing and includes 10 Signal issues/month, 25k trace spans/month, 1 GB ingestion/month, and 15-day retention. AX Pro costs $50 a month, with 25 Signal issues/month, 50k trace spans/month, 10 GB ingestion/month, and 30-day retention. Enterprise pricing is custom. Self-hosted deployment keeps observability data, authentication, APIs, and UI within customer infrastructure; air-gapped deployment is available.

VoltOps is a console for observing, automating, evaluating, deploying, and managing AI agents, with prompt management and guardrails. It traces LLM calls, tool executions, and agent interactions, with session replay and payload inspection. Alerts can cover latency, errors, and token usage, with notifications through Slack, email, or webhooks. Evaluation tools include reusable datasets, queued parallel test cases, multiple scorers, and comparisons across runs. Prompt management versions edits, supports rollback and promotion to staging or production, and handles JSON import and export. Automation provides actions for Airtable, Discord, and Gmail, plus triggers for Slack messages, Gmail emails, GitHub webhooks, and Airtable updates. RAG supports document uploads, Notion syncing, and website crawling without setting up a vector database. Deployment includes custom domains, SSL provisioning and renewal, real-time logs, and HTTP Basic Auth. The Developer plan costs nothing and includes one seat, project, and prompt, plus 250 traces per month and seven days of retention. Core costs $50 a month; Pro costs $250 a month. Both include a 14-day free trial. Enterprise pricing is custom and includes self-hosted deployment.
