Ranked by the number of objective advantages each alternative has over the app (cheaper estimated server cost, lighter official RAM figure, no GPU needed, fewer license conditions, better maintenance status, at least 1.5× the GitHub stars, simpler deploy). Ties: same-category apps first, then more GitHub stars. License order used: Permissive (MIT/Apache) → Open core → Copyleft (GPL) or Custom conditions → Network copyleft (AGPL) → Source-available. Archived projects are not listed as alternatives.
