Pros & Cons

Tabby

  • Genuinely free for unlimited self-hosted use with no per-seat cloud fees
  • Enterprise features (codebase indexing, SSO, team management) included free rather than upsold
  • Cloud Team option provides managed hosting convenience without giving up the open-source foundation
  • Self-hosting requires managing your own GPU infrastructure unless using Cloud Team
  • Cloud Team’s $24/user/month adds cost for teams wanting managed hosting convenience
  • Community-driven support model for the free tier, without dedicated commercial support

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
