# Fauna > One account, one API key and one prepaid wallet for Parrot, Marmot, Ant, Magpie, Cicada and Termite, with SDKs in TypeScript and Rust. Fauna is one account, one API key and one prepaid wallet for six products: Parrot, Marmot, Ant, Magpie, Cicada and Termite. Sign in once and every product knows you; they share your credits, your groups and your files. ## Credits and billing - Prepaid, by the call: add credit once and spend it in any product. Every call is metered at its own price and drawn from the same balance. - $1 free every month: every free account gets $1 of credit when it signs up and again at the start of each month. Credit stacks on the balance. - Premium adds $5 of credit with each paid invoice. Add ons that apps sell join the same subscription. - Groups pay for their members: a group's calls bill the group's wallet, and every group gets $1 of its own each month. ## SDKs - TypeScript (`fauna-api`), for Node and the browser: every product and every route, the same calls Fauna's own apps are built on. - Rust (`fauna-api` crate): async on Tokio with typed results and errors, mirroring the TypeScript SDK file by file and function by function. ## Links - [Open Fauna](https://app.faunakit.com) - [Create an account](https://app.faunakit.com/authentification/register/) - [Terms of use](https://faunakit.com/policies/terms_of_use.pdf) - [Privacy policy](https://faunakit.com/policies/privacy_policy.pdf) ## Products - [Parrot](https://parrotmodels.com/): One API for every model. - [Marmot](https://marmotresearch.com/): Turns noise into structure. - [Ant](https://antinsight.com/): Persona simulations. - [Magpie](https://magpieassets.com/): Every shiny thing in one nest. - [Cicada](https://cicadaflow.com/): Every conversation, one signal. - [Termite](https://termitecloud.com/): A real cloud machine for every repository.
