- You need Self-hosted or Permissive training data, which Windsurf doesn't offer.
- You mostly do enterprise dev or self-hosted ai.
- You need real autonomous-agent capability (plan + execute multi-step tasks), not just chat.
- You need Cascade agent or Inline edits, which Tabnine doesn't offer.
- You mostly do agentic coding or refactoring.
