Updated May 18, 2026
The list includes 2 free alternatives and 47 freemium, so whether you're looking for a no-cost replacement or a more capable paid tier, there's an option to compare. Kiwi Fitness itself is freemium, which makes freemium alternatives the most natural starting point.
Many of these tools cluster around use cases like Free + From $9.99/mo, Api, Chatbot, and Music Production — the same problem spaces Kiwi Fitness addresses. Cross-referencing tools that overlap on multiple topics gives a more reliable signal than category alone, because two products in the same category can still serve very different workflows.
Our ranking weighs eight signals: shared category, topic overlap, feature overlap, name and description text similarity (via PostgreSQL's pg_trgm and tsvector), Bayesian-smoothed user ratings, pricing-model match, popularity, and editorial overrides. Scores are then normalized within each tool's own candidate pool so the top match always represents the strongest available alternative.
