Does Regex Droid Studio execute 100% in the browser?

Yes, all regex AST parsing, railroad diagram synthesis, ReDoS catastrophic backtracking analysis, and multi-language code generation run completely client-side in the browser.

What is ReDoS and how does Regex Droid Studio detect it?

Regular Expression Denial of Service (ReDoS) occurs when catastrophic backtracking causes exponential CPU freeze. Regex Droid Studio inspects nested quantifiers, overlapping alternations, and unanchored wildcards directly in the browser.

What programming languages are supported for code export?

Production-ready bindings are generated for Python (re), JavaScript/TypeScript (RegExp), Rust (regex crate), Go (regexp), and PHP (preg_match).
