What it does

Flask is a popular open-source toolkit that helps developers quickly build websites and web applications using the Python programming language, without locking them into a rigid structure or set of rules. It's designed to be simple enough for small projects but flexible enough to grow into large, complex products.

Why it matters for PMs

With over 71,000 stars and nearly 17,000 forks on GitHub, Flask is one of the most widely adopted web development tools in the world, meaning a huge pool of developers already know how to use it — reducing hiring friction and onboarding time. Teams choosing Flask can move fast in early stages without being forced into technical decisions that might not fit their product's future direction.
