The short version

  • Only Weka has a free tier, so it costs nothing to try first.
  • Each has a real cost: Manus specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Manus

  • Specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales
  • Organisational transition mid-2026; unclear how this affects feature stability or pricing continuity
  • No clear free tier mentioned; access requires subscription from apparent launch
  • Limited public documentation on capabilities and limitations

Weka

  • The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
  • Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture
