Actix vs Spring Boot
No clear leader: Spring Boot (63.3) and Actix (60.6) are within the 5-point margin; treat as a tie. The attribute-by-attribute breakdown below, with a source and date on every value, is the honest way to compare them.

What each one is
The product in its own terms, so the numbers below have context.
Actix
Actix Web is a Rust web framework emphasizing speed and type safety in HTTP request handling. It uses an actor-based concurrency model where independent components communicate through strongly-typed messages, with built-in support for HTTP/2, flexible response types, and powerful request extraction.
Spring Boot
A framework for creating stand-alone, production-grade Spring applications with minimal configuration. Features embedded web servers (Tomcat, Jetty, Undertow), opinionated starter dependencies, automatic configuration, and production-ready features such as metrics and health checks.
Platform & deployment
Where each product runs and how it can be hosted. A dash means undocumented, not unsupported.
