Which is cheaper, Bazel or Depot?

Bazel starts at Free and Depot at Free.

Does Bazel or Depot run on more platforms?

Bazel runs on Windows, macOS, Linux. Depot runs on Cloud, GitHub, CLI.

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 Depot is typically brought in for.

What can Bazel do that Depot cannot?

Bazel covers Fast incremental builds, Multi-language support, Parallel execution, Dependency analysis. Depot covers Depot CI, Container builds, GitHub Actions runners, Build API. Both handle Distributed caching.
