Answered from the vendors’ own pages

Flask: Is Flask free to use?

Yes. Flask is open-source software released under the BSD-3-Clause License, available free for any use including commercial applications.

Source
pnpm: Is pnpm free and open source?

Yes. pnpm is free and open source software developed for Node.js. Version 10 and 11 are currently available.

Source
Flask: What are Flask's core dependencies?

Flask depends on three main libraries: Werkzeug (WSGI toolkit), Jinja (template engine), and Click (CLI toolkit).

Source
pnpm: How does pnpm save disk space?

pnpm uses a content-addressable store with hard linking and symlinks to avoid duplication. All files are saved in a single place on disk and hard-linked to individual projects, dramatically reducing storage requirements compared to npm.

Source
Flask: Does Flask provide built-in database support?

No. Flask is a microframework that does not include built-in database support. Developers must choose and integrate their own database libraries, though Flask-SQLAlchemy is a popular community extension.

Source
pnpm: Is pnpm faster than npm?

Yes. pnpm performs installation in three stages: dependency resolution, directory structure calculation, and linking. Packages are fetched and linked as soon as possible, making it significantly faster than npm's sequential approach.

Source
Flask: What platforms does Flask support?

Flask is a microframework for Python that runs on any platform that supports Python, including Linux, macOS, Windows, and cloud platforms.

Source
pnpm: Does pnpm support monorepos?

Yes. pnpm has built-in support for monorepositories. You can create a workspace using pnpm-workspace.yaml to unite multiple projects in a single repository.

Source
Flask: Can Flask scale to large applications?

Yes. While designed to be lightweight and simple, Flask is designed with the ability to scale up to complex applications through blueprints, extensions, and modular architecture.

Source
pnpm: How does pnpm handle node_modules differently than npm?

pnpm uses symlinks to add only direct dependencies to node_modules root, preventing accidental access to undeclared dependencies. This encourages more explicit dependency management compared to npm's flattened node_modules structure.

Source
Flask: Does Flask require a build step to run?

No. Flask does not require a build step. Applications can run directly with the Flask development server using 'flask run' from the command line.
