What do real users say about Container Diet vs Spider Cloud?

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Container Diet

37 mentions across 3 sources · 30% positive — critical (weighted across 3 sources)

YouTube, Product Hunt, Lemmy

What users praise

  • • Free and MIT-licensed, so teams can audit it without procurement friction
  • • Local-only analysis via Ollama keeps sensitive images from leaving the network
  • • Combines size bloat and security hardening in a single CLI pass
  • • Auto-fix generates a downloadable Dockerfile.diet with multi-stage builds and slim bases

What frustrates them

  • • Users repeatedly ask how it differs from prompting a general LLM directly
  • • No documented evidence of successful runs on large, real-world images
  • • AI-suggested Dockerfile rewrites may break runtime dependencies without careful review
  • • Community discussion is dominated by launch-day speculation, not production testimonials
