Check Go code for structural errors, unused imports, risky patterns, and basic quality issues directly in your browser. Processing runs locally in your browser and produces copy-ready output with practical review notes.
Check Go code for structural errors, unused imports, risky patterns, and basic quality issues directly in your browser.
Browser-based analysis cannot replace the official compiler, formatter, linter, module resolver, or project test suite. Verify production code with the appropriate Go or Rust toolchain.
Input:
package main
import (
"fmt"
"strings"
)
func main() {
fmt.Println("Hello, Go")
}Output: Load the included example and click Check Code to produce a complete, testable result in the output card.Paste Go source into the checker and run the browser-based structural analysis. It detects common syntax patterns, delimiter errors, imports, and risky constructs, but official compiler verification still requires go build or go vet.
The checker extracts imported package names and looks for qualified usage in code outside comments and strings. Review aliases and blank imports manually because browser analysis cannot reproduce the full compiler.
A browser checker does not perform type checking, module resolution, build tags, generics instantiation, or dependency compilation. Run go build for authoritative results.
Enable risky-pattern checks to flag assignments to the blank identifier, suspicious unchecked calls, and empty error branches. These are heuristics and should be reviewed in context.
No. It is useful for fast structural feedback, while go vet performs compiler-aware analysis and should remain part of the project workflow.
| Module | Purpose |
|---|---|
| Input normalization | Normalizes line endings and safe whitespace. |
| Static processing | Runs the selected analysis, transformation, or generation logic. |
| Result metrics | Reports characters, lines, bytes, status, and processing time. |
