Is Bazel or Consul better?

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

Which is cheaper, Bazel or Consul?

Bazel starts at Free and Consul at Free.

Does Bazel or Consul run on more platforms?

Bazel runs on Windows, macOS, Linux. Consul runs on Linux, Windows, Mac, Cloud.

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 Consul is typically brought in for.

What can Bazel do that Consul cannot?

Bazel covers Fast incremental builds, Multi-language support, Distributed caching, Parallel execution. Consul covers Service discovery, Health checking, Key/value store, Multi-datacenter.

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

Consul

Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead
