From the faq (http://bazel.io/faq.html):

Did you rewrite your internal tool as open-source? Is it a fork?

Bazel shares most of its code with the internal tool and its rules are used for millions of builds every day.

What's up with the word "Blaze" in the codebase?

This is an internal name for the tool. Please refer to Bazel as Bazel.

Blaze is the internal name of Bazel in Google (I don't know if both projects are identical, or if Blaze was just the "inspiration" for Bazel)

They refer to distinct things but share a lot of their code. Blaze doesn't contain anything that you would find useful, you need our infrastructure for its other features to work.

Blaze is the Google-internal thing. Bazel is its Open Source clone.
