Interactive prompt for debuggingmedium

↓ Weaknesses

Limited to UNIX-based systems due to reliance on UNIX socketshigh

Manhole uses UNIX socket connections which are not available on Windows without additional software.

Requires manual setup and configuration for each applicationmedium

Documentation lacks detailed step-by-step instructions for integrating Manhole into existing projects.

Small community and limited third-party support or integrationshigh

The project has a small number of contributors and limited third-party plugins or integrations available.

Performance overhead when Manhole is enabled in production environmentsmedium

Enabling debugging features can introduce additional latency and resource usage, impacting application performance.
