Is this tool completely free to use?

Yes, this tool on Forgenos is 100% free to use. There are no subscriptions, no hidden fees, and no signups required.

How does this tool detect ReDoS vulnerabilities?

It generates synthetic text payloads of varying sizes and benchmarks the execution time. If the pattern takes exponentially longer to fail, it flags a catastrophic backtracking (ReDoS) risk.

Do I need to download software to test regex performance?

No, our regex execution profiler is fully browser-based. It runs entirely within your device's web browser using isolated web workers.

Is my regex pattern data secure?

Absolutely. All stress testing and pattern analysis happens locally on your machine. No code or data is ever sent to or stored on our servers.

Why is my regex failing the stress test?

If your execution time spikes into the extreme risk category, your pattern likely contains overlapping nested quantifiers (like (a+)+) which cause catastrophic backtracking when matching fails.

About REGEXDRILL

REGEXDRILL is an advanced execution profiling and ReDoS (Regular Expression Denial of Service) detection engine. It evaluates your regex patterns against simulated synthetic payloads to benchmark performance and identify catastrophic backtracking risks before they cause server downtime or application freezing.

Key Features

Instantly identify ReDoS vulnerabilities and risks.
Benchmark execution time across multiple iterations.
Simulate heavy traffic with dynamic 1MB to 10MB payloads.
Browser-isolated web workers prevent UI freezing.
100% private processing — no data sent to external servers.

How to Use

Enter your target Regular Expression pattern in the input field.
Specify standard regex flags (e.g., g, i, m).
Select the synthetic payload size to define stress intensity.
Click "Initiate Regex Stress Test" to begin profiling.
Review average execution time, max spikes, and risk levels in the telemetry dashboard.

Who It's For

Backend Engineers, Security Analysts, Full-Stack Developers, and QA Testers validating input sanitization rules against malicious exploits.
