Is Bazel or CloudAMQP better?

Neither clearly leads. Bazel starts at Free and CloudAMQP at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Bazel or CloudAMQP?

Bazel starts at Free and CloudAMQP at Free.

Does Bazel or CloudAMQP run on more platforms?

Bazel runs on Windows, macOS, Linux. CloudAMQP runs on Web.

Can I use Bazel for free?

Both have a free tier, so you can try either at no cost before committing.

What is Bazel best used for?

Bazel is most often used for building large monorepos with hundreds of interdependent projects, multi-language projects requiring consistent build semantics, organizations requiring reproducible builds and hermetic test execution, teams implementing distributed ci with shared build artifact caching. Of those, building large monorepos with hundreds of interdependent projects and multi-language projects requiring consistent build semantics are not what CloudAMQP is typically brought in for.

What can Bazel do that CloudAMQP cannot?

Bazel covers Fast incremental builds, Multi-language support, Distributed caching, Parallel execution.
