The short version

  • Each has a real cost: Amazon Q Developer deepest value and AWS-specific expertise is tied to the AWS ecosystem, less compelling for non-AWS shops; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • They diverge on capability: Amazon Q Developer covers Code generation, Weka covers Classification.

Where each one falls short

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

Amazon Q Developer

  • Deepest value and AWS-specific expertise is tied to the AWS ecosystem, less compelling for non-AWS shops
  • Free tier caps agentic requests at 50 per month, which can be exhausted quickly on larger tasks
  • Additional transformation usage beyond plan limits is billed per line of code, adding unpredictable costs
  • GitHub and Eclipse integrations are still in preview, indicating incomplete platform coverage

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
