Lucide and Phosphor Icons land in similar territory on the hard numbers, so the decision comes down to fit with your workflow rather than a headline metric. Lucide is built for modern web apps wanting a clean, consistent, community-maintained icon set and is not a fit for projects needing multiple visual weights, duotone styles, or mobile-native icon packs. Phosphor Icons is built for brands wanting expressive weight variation across web, mobile, and flutter products and is not a fit for ultra-minimal uis or projects where single-weight consistency is the goal. On the scoring side, Lucide rates 5/5 for developer experience and 5/5 for transparency; Phosphor Icons rates 5/5 and 5/5 respectively. The honest trade-off: with Lucide you accept that single visual weight limits stylistic variation, while Phosphor Icons comes with the reality that larger catalog than needed for simple uis. Neither side is free. Lucide's headline strength in the data is that actively maintained fork of feather with 1000+ icons.
Quick take
Lucide is for modern web apps wanting a clean, consistent, community-maintained icon set; Phosphor Icons is for brands wanting expressive weight variation across web, mobile, and flutter products; decide based.
Both list a free pricing model in our data, and both publish a free tier. We don't have per-seat numbers in this dataset, so 'cheaper' depends on volume. Price both on your actual usage before deciding.
Can I migrate from Lucide to Phosphor Icons?
Lucide has low lock-in (oss icon library); Phosphor Icons has low lock-in (open source icon library, free to use). Migration effort scales with how much state and automation you've built in Lucide; plan for data export, config rebuild, and a parallel-run period before cutting over.
Which has better developer experience?
Both Lucide and Phosphor Icons score 5/5 on developer experience in our data, so DX isn't the tiebreaker here. Decide on fit, pricing, or lock-in instead.
Is Phosphor Icons a good alternative to Lucide?
Phosphor Icons is built for brands wanting expressive weight variation across web, mobile, and flutter products and explicitly not for ultra-minimal uis or projects where single-weight consistency is the goal, so it's a fit only if your workflow matches its stated audience. If you were using Lucide for modern web apps wanting a clean, consistent, community-maintained icon set, the switch is reasonable; outside that scope, look elsewhere.
