Auth & Usage-Based Billing

Base316

Sign them in. Meter what they use. Bill them for it.

Base316 is the identity provider your customers' users sign in through and the billing engine that meters what they use and invoices them for it. Because sessions, organizations, entitlements, metering, and invoices share one model, what a customer is allowed to do and what they're billed for can never disagree.

What you get

Everything below is built and shipping today, unless flagged otherwise.

Auth & enterprise SSO

Sessions, organizations, and permissions, with an OIDC provider and enterprise SSO over OIDC and SAML.

Usage metering

Meter whatever your product counts and turn it into entitlements and invoices automatically.

Billing on Stripe Connect

Plans, catalog, and invoicing built on Stripe Connect — get paid without building a billing system.

Built for developers

REST API, SDKs, a CLI, and an MCP server so your coding agent can wire it up too.

Why teams choose Base316

The unfair advantages baked into the product.

Auth and billing in one model — entitlements and invoices can't drift apart
One call answers both "may they?" and "who pays?"
Enterprise SSO included, not an upsell
API-first, with an MCP server for agent-driven setup

Built for saas founders, product & platform engineers.

Base316 is opinionated about who gets the most out of it. If that's you, the on-ramp is fast.
