The short version

Only Bazel has a free tier, so it costs nothing to try first.
Each has a real cost: Bazel steep learning curve for developers unfamiliar with build systems; Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
They diverge on capability: Bazel covers Fast incremental builds, Redocly covers OpenAPI reference docs.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bazel

Steep learning curve for developers unfamiliar with build systems
Initial setup complexity; requires BUILD files and Bazel configuration
Verbose error messages can be difficult to debug for new users
Smaller community and fewer third-party integrations vs enterprise tools

Redocly

Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
The portal and governance features are paid, while the open-source renderer covers only reference rendering
Linting rules are another thing to configure and argue about before value appears
Narrower than a general documentation platform, by design

Answered from the vendors’ own pages

Bazel: Does Bazel support distributed builds across CI infrastructure?

Yes, Bazel supports distributed execution and remote caching, allowing build work to be distributed across multiple machines and CI agents.

Source

Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.

Bazel: What languages can be built with Bazel?

Bazel has built-in support for Java, C++, Go, Python, and Android/iOS development, with additional language support available through custom rules and community extensions.

Source

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Bazel: Can I use Bazel for small projects or is it only for large monorepos?

While Bazel excels at handling large projects, it can be used for smaller codebases. However, the setup overhead may not be justified for very small or simple projects.

Source

Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.
