Feather Icons is a solid choice — 286 icons, MIT licensed. But it is not the only one, and it is not the best fit for every project. Below are 8 open-source alternatives ranked by how directly they answer the reasons people look for a replacement: more coverage, more visual range, or a simpler license.

Landing pages, portfolios, marketing sites, and small apps where you need perhaps thirty icons and want them to look calm and deliberate. Feather is also a good teaching reference for icon grid discipline.
For an actively maintained superset with the same aesthetic, use Lucide — it began as a Feather fork and now has 1,979 icons. Iconoir is another minimalist option with far more coverage.
Start from the constraint that actually binds your project. If it is coverage, sort by icon count — the difference between a 286-icon set and a 20,000-icon set is whether you ever have to design a glyph yourself. If it is visual range, look at variants per concept: a library with six weights lets you build hierarchy without a second dependency. If it is legal simplicity, avoid CC BY sets where attribution is impractical.
All of these libraries are indexed on IconStash, so you can search one concept and compare how every set drew it before committing.
The usual reasons are coverage, style range and licensing. Feather Icons ships 286 icons in outline only. If you need concepts it does not cover, or several visual weights from one set, or a license without attribution, one of the alternatives below will fit better.
Every library listed here is open source and free for commercial use. Most are MIT, ISC or Apache 2.0, none of which require attribution. The exception in this list is any CC BY 4.0 set, which does require a visible credit — check the license column in the table above before committing.
Technically yes, but mixing sets usually looks inconsistent because each one draws to its own grid and stroke weight. If you need to fill a gap, prefer pulling a single icon and redrawing it to match your primary set.
