It comes down to fit, not a single winner: GitHub Copilot leans into real-time code completion, while Semgrep is built for SAST static analysis with custom rule support. GitHub Copilot edges the Editor Score (4.7 vs 4.5), but a 0.2-point gap rarely outweighs picking the tool whose features match your work. Semgrep is the lower-cost place to start thanks to its free or freemium plan; the other is worth a trial if its feature set fits better.
GitHub Copilot has the higher AInexfinder Editor Score (our editorial rating from features, value and pricing, blended with verified user reviews where a tool has them), but "better" depends on your needs — compare features, pricing and the pros & cons above to decide.
