Pay for support, not tokens.
Tangison Agent uses a bring-your-own-model-key approach on every tier, including Enterprise. You pay your model provider directly for the tokens you consume, and you pay Tangison only for the support and tooling you actually use. The Self-Host tier is free forever under an MIT license, the Supported tier is a flat monthly fee for teams in production, and the Enterprise tier is a contact plan for organizations that need a hardened appliance and SAML SSO. There is no per-seat pricing, no usage markup, and no credit system. The full source lives at github.com/tangison/agent, and the project is run from tangison.com by Tangison, an independent brand founded by Tangi Iigonda.
Three tiers
Pick the level of support you need
Every tier includes the full agent, all seven built-in skills, and the ability to run unlimited agents on your own hardware. The difference between tiers is the level of human support Tangison provides, not what the agent can do. The Supported tier is the one we recommend for any team shipping to real users, because priority email and monthly office hours with Tangi pay for themselves the first time something breaks. The brand behind this pricing page is at tangison.com.

All prices are in USD. The Supported plan is billed monthly with no annual contract, cancel anytime from the dashboard.

The model bill goes straight from your model provider to you.
