The short version

  • Only Weka has a free tier, so it costs nothing to try first.
  • Each has a real cost: Tabnine no published free tier as of the current pricing page, unlike several competitors that offer free individual plans; 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: Tabnine covers Code Completions, Weka covers Classification.
  • 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.

Tabnine

  • No published free tier as of the current pricing page, unlike several competitors that offer free individual plans
  • Pricing is higher than many consumer-focused AI coding assistants, targeting enterprise budgets
  • Now owned by Tricentis, a testing-focused company, introducing uncertainty about long-term product direction outside quality engineering use cases
  • LLM usage costs apply separately when using Tabnine-provided model access, on top of the per-seat license fee

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
