Where each one falls short

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

Bootstrap

  • Default styling is recognisable, so sites can look generic without deliberate customisation
  • Ships a large stylesheet, and unused CSS must be purged to keep payloads reasonable
  • Component-based approach fits less naturally into React and Vue codebases than libraries designed for them

Earthly

  • Pricing model not published; requires sales contact
  • Earthly Lunar is a recent launch (2025) with limited track record
  • Primarily GitHub-focused; limited integration with other platforms
  • No public documentation on pricing or feature tiers

Lunar converts engineering standards, compliance requirements, and processes documented in AGENTS.md files, wikis, and incident postmortems into enforceable guardrails that apply consistently across repositories and development stages.
