🏆 Recommendations Based on Your Needs
- Best for Comprehensive Features & Enterprise Use: OpenProject – Offers a wide range of features suitable for complex project management needs. Ensure compliance with GPLv3 if reselling.

⚠️ Licensing Considerations
- MIT License: Highly permissive; allows for modification, redistribution, and commercial use with minimal restrictions.
- GPLv3: Requires that any modified versions distributed (including as a service) also be open-sourced under the same license.
- AGPLv3: Similar to GPLv3 but extends the requirement to services offered over a network, necessitating source code disclosure even for hosted applications.
- CPAL: Allows for commercial use but requires attribution and may have other specific conditions.
Ensure you review each license’s terms to maintain compliance, especially when planning to modify or resell the software.
