Side-by-side comparison of two listed Dev Tools — real listing data only, no paid placement.
On record, they differ in: unique tags (Windsurf 2: #ide #autocomplete vs Tabby 3: #open-source #self-hosted #code-completion); category rank (Windsurf #44 vs Tabby #45). Same pricing model (Freemium) and category (Dev Tools). Listing facts only — not a recommendation.
