Bazel can be amazing for bigger projects, but setting it up takes a lot of time, which startups often don't have. It's crucial to focus on building a product quickly before diving into complex systems.
Using Bazel with languages like Python and JavaScript can be tricky because they aren't as well supported. It can lead to a lot of wasted effort if you're not careful about the tools you choose.
While Bazel has great potential, it's often not the right choice for startups due to the time and resources needed. It's better to find a simpler solution until you have a stable system.
