Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The tool primarily focuses on URL detection and does not easily support complex or custom link types without significant code modification.
Documentation is sparse on how to extend the library's functionality beyond basic usage, leaving users to decipher source code.
Being an open-source project with no dedicated maintainers can lead to slower issue resolution and feature updates.
Some unconventional or less common URL structures may not be detected, leading to incomplete link parsing in certain scenarios.
