What criteria do you follow when choosing a suitable framework for implementing a project?

When choosing a framework for a project, I consider the following criteria:

• Project requirements: what tasks need to be solved, which platforms to support (web, mobile, desktop).
• Programming language: how familiar the team is with the language on which the framework is based.
• Community and support: community activity, availability of documentation, examples, and libraries.
• Performance: how suitable the framework is for the required performance.
• Ease of development and maintenance: how easy it will be to develop and support the project.
• Compatibility with other tools: integration with databases, services, CI/CD.
• License and cost: whether the framework is open-source, any restrictions.

For example, for a web project with rapid prototyping and a large community, one might choose Django or Flask; if simplicity and speed of development are important — Flask. If scalability and rich functionality are needed — Django.
