## The Hook

Tokio is the async foundation everything Rust builds on.

## What's Good

Battle-tested at scale by Discord, Cloudflare, and more. The ecosystem (Axum, Tonic, Tower) is comprehensive. Work-stealing scheduler is efficient. The documentation is excellent.

## The Catch

Async Rust has a learning curve. Stack traces are confusing. Some patterns from other languages do not translate.

## Verdict

The async runtime that powers production Rust.
