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

Cabin

  • The analytics are deliberately shallow: no funnels, no cohort retention, no session replay and no user-level journeys, so anything beyond traffic and event counts requires a second tool
  • Carbon figures are modelled from bytes transferred using CO2.js assumptions about grid intensity and device energy, not measured, so they are directionally useful and should never be presented as audited emissions data
  • Cabin is a product of Normally, a design studio, rather than a company whose sole business is analytics, which puts a reasonable question mark over long-term roadmap investment and support depth
  • The 30-day retention on the free tier and 12 months on Plus mean year-on-year comparison needs the $45 Scale plan, which is a large jump for a small site that only wanted longer history
  • Because it does not use cookies or cross-site identifiers, returning-visitor and multi-session attribution are approximations, which matters if anyone in the business is trying to reconcile it with an ad platform's numbers

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
Cabin: Do I need a cookie consent banner with Cabin?

No. It sets no cookies and collects no cross-site identifiers, and data is stored in the EU, which is the specific reason most buyers switch to it.

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
Cabin: How accurate is the carbon measurement?

It is an estimate derived from data transfer using the CO2.js model. It is reliable for tracking change over time on your own site and unsuitable as an audited emissions figure.

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
Cabin: Who makes Cabin?

It was built at Normally, a research and design studio in London, out of work on data, privacy and the carbon footprint of digital products.

Cabin: Can it replace Google Analytics entirely?

For traffic, referrer and event reporting, yes. For advertising attribution, audience building and funnel analysis, no.
