Overview
async-graphql is a GraphQL server library for Rust. It supports static and dynamic schemas, asynchronous resolvers, subscriptions, uploads, DataLoader, Apollo Federation, and integrations with Poem, Axum, Actix Web, and other HTTP servers.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Define GraphQL schemas and resolvers from Rust types and macros
Procedural macros such as Object map Rust types and methods to GraphQL objects and fields. Both static and dynamic schemas are supported, with async/await used for resolver execution.

Extend servers with subscriptions, DataLoader, and Federation
Features include WebSocket subscriptions, batch queries, DataLoader, persisted queries, Apollo Federation v2, and custom extensions. HTTP framework adapters are provided as separate integration crates.
Sources: [2]
Best fit
Fits Rust services adding a GraphQL execution layer to an existing HTTP stack
It integrates with Poem, Axum, Actix Web, Warp, Rocket, and other frameworks while keeping schema types and resolver implementations in Rust.

Before adoption
Enforce query limits and separate stable 7.2 from the 8.0 RC development line
The README recommends limiting query complexity, depth, and directives in production. The stable 7.2.1 Cargo manifest declares Rust 1.89, while the default branch is on the 8.0.0 RC line, so production adoption should distinguish stable APIs from RC breaking changes.

Supplemental curator note
async-graphql models schemas through Rust types and procedural macros, then connects to servers such as Poem or Axum through integration crates. Production schemas should set explicit complexity, depth, and directive limits rather than accepting unbounded query cost.
Try it in 3 steps
- 1
Clone the stable 7.2.1 source and examples
Pin the commit recorded in the crates.io 7.2.1 package and initialize the matching official examples submodule.
