Meterbox is a usage-based billing platform for AI and software companies: metering, entitlements, credits, and billing as one system you configure, not five systems you reconcile. It runs in-cluster (in your own environment or ours) so metering sits in the request path instead of behind an external API call.

Three plans: Free (forever, up to 10 customers and 250K events/month), Pay as you go ($249/month, up to 500 customers and 10M events/month included), and Enterprise (custom contract, unlimited customers, custom SLA). Every plan includes the full API surface — nothing is feature-gated.

On Free, metering calls past 250K events/month or 10 customers are rejected (a 402 response) until you upgrade. On Pay as you go, usage bills automatically instead of blocking: $10 per additional 1M events and $0.30 per customer past the included 500 — no manual intervention required.

Yes. The Self-Managed tier deploys the same APIs into your own cloud (EKS, GKE, AKS, k3s, OpenShift, or on-prem) with a bundled database and cache — no managed services required. It supports bring-your-own KMS, Vault, or Sealed Secrets, and can run fully air-gapped with any outbound integration (Stripe, Zuora, webhooks) disabled per environment.

In-cluster, by design. Meterbox doesn't require external managed datastores — Postgres, Redis, and backups run alongside the application in the same environment. On Cloud, each tenant gets a fully isolated data plane (separate compute, storage, and database); on Self-Managed or Managed, it never leaves infrastructure you control.

Cloud is SOC 2 Type II. Self-Managed is HIPAA-ready with an ISO 27001 path. The Managed (sovereign) tier targets FedRAMP Moderate (in progress), HIPAA, GDPR data residency, and ISO 27001, with an annual external pentest report shared directly with you.

Yes, on Pay as you go and Enterprise plans. Multi-region adds $49/month on top of your plan price.

Stripe and Zuora are both supported out of the box for subscription and invoice collection. You can also disable outbound billing-provider integrations entirely per environment if you'd rather handle collection yourself.

There's a Free plan you can use indefinitely, not just a trial — up to 10 customers and 250K events/month, with the full API surface, in-cluster metering, and ledger/statements included. Upgrade whenever you outgrow it.

Free includes community support. Pay as you go includes email support with a 4-hour SLA. Enterprise includes a named CSM, custom SLA, and a dedicated Slack channel. For anything else, reach us directly at contact@meterbox.ai.
