OpenMeter vs Revenium

OpenMeter is an open-source platform for measuring product usage, controlling access, and supporting billing for AI, API, SaaS, and developer-tool products. It combines a REST API, client SDKs for Node.js, Python, and Go, and collectors for systems such as Kubernetes, S3, OpenTelemetry, PostgreSQL, ClickHouse, LangChain, Prometheus, Nvidia Run:ai, and Redpanda Connect. Usage events can be aggregated in real time, with quotas, limits, notifications, and edge usage gating. Its product catalog handles plans, entitlements, credits, usage-based pricing, add-ons, discounts, and commitments. Billing supports subscriptions, prepaid credits, customer portals, auditable outputs, proration, tax automation, and multi-currency billing. Stripe can synchronize invoices and assist with tax calculation and payment collection. Teams can self-host under the Apache 2.0 license or use Konnect Metering & Billing. OpenMeter Cloud states SOC 2 Type 2 compliance, AES-256 encryption at rest, HTTPS/TLS in transit, SAML single sign-on, and role-based access control. The free plan has no numeric rates published; pricing directs visitors to sales.

Revenium tracks AI usage costs, provides spending controls and connects costs with business outcomes. It attributes model calls, agent turns and tool calls to teams, customers, features and agents, for engineering, finance, FinOps and product teams. Spend guardrails, alerts and budget thresholds can block or throttle requests that exceed configured limits. For ROI analysis, it relates AI costs to total cost of ownership, cost of goods sold and return on investment per workflow, including tool calls and human rescue time. Revenium is available through web and API, and lists integrations such as Arize, Ollama, ClickHouse, LangChain, GitHub, Anthropic, OpenAI, Google Gemini, Databricks, Datadog, Snowflake and Claude. Named providers include OpenAI, Anthropic, Azure OpenAI, AWS Bedrock, Google Vertex AI and custom models through its SDK. Its free Observe plan includes 100,000 transactions per month, seven days of retention and one user. Growth includes 350,000 transactions monthly, 90 days of retention and 10 users; the listed Enterprise plan includes 1M+ transactions and unlimited users. Revenium says it meters usage metadata and requires opt-in for payload capture.
