Grafast is an exciting new execution engine for GraphQL that enables greater efficiency across your entire backend stack by leveraging query planning.

The source code for the TypeScript implementation of Grafast is currently in the /grafast/grafast folder of the Graphile Crystal monorepo; this enables faster feedback on changes due to the integration tests of the related projects. For Grafast version 1.0 we plan to build a specification, and a reference implementation in a different programming language.

In the mean time, this organization hosts the Grafast working group for anyone interested in getting involved in the future of Grafast.
