Our Take on Each
Codeium (Windsurf)
Best for: Free AI coding with an agentic IDE
Codeium (now Windsurf) has one of the most generous free tiers in AI coding, and its agentic IDE is closing the gap with the paid leaders quickly. Being newer, it has the occasional rough edge, but the capability you get for the price is genuinely hard to argue with.
Tabnine
Best for: Privacy-focused and enterprise teams
Tabnine's whole pitch is privacy — it can run locally or on-prem and learn from your own code, which matters when security rules are strict. Its raw suggestions aren't as sharp as Copilot's, but for regulated teams that trade-off is usually worth making.
Verdict: Codeium (Windsurf) or Tabnine?
Both hold up well. If you value Codeium (Windsurf)'s approach, its Free / $15-60/month tier is worth a look; if Tabnine's feature set matches your needs, Free / $9-39/month is money well spent. Codeium (Windsurf) edges the ratings race by a hair.
