A highly extensible Go source code linter providing opinionated checks for bugs, performance, and style issues.
go-critic is a static analysis tool for Go that performs deep code audits beyond what other linters offer. It focuses on detecting bugs, performance issues, and style violations through a comprehensive set of nearly 100 checkers, making it a valuable addition to any Go developer's toolkit.
Go developers and teams seeking rigorous, opinionated static analysis to enforce code quality, performance, and style beyond standard linters, particularly those integrating with tools like golangci-lint.
Developers choose go-critic for its extensive, extensible diagnostics and opinionated checks that catch issues other linters miss, with dynamic rules via ruleguard allowing custom linting without recompilation.

With nearly 100 checkers for bugs, performance, and style, it provides comprehensive analysis beyond standard linters like golint, catching subtle issues others miss.
Integrates with ruleguard for adding custom linting rules without recompilation, offering flexibility for team-specific needs and future-proofing.
The `go-critic doc <checkname>` command provides instant documentation for each checker, reducing the learning curve and enhancing usability during code reviews.
Checkers are organized into tags like #diagnostic and #performance, allowing targeted analysis for specific goals such as performance optimization or bug detection.
Managing numerous checkers and tags, especially with opinionated and experimental ones, requires careful setup and can be complex for new users or simple projects.
The #opinionated checks are very strict and disabled by default, which may not suit all projects, potentially causing friction in teams with varied coding preferences.
Checkers tagged as #experimental are under development and disabled by default, leading to potential inconsistencies, false positives, or breaking changes in updates.
