by Vernon Adams
Nunito shares Avenir's geometric, slightly rounded character. Slightly less refined but free and approachable.
Linotype / Monotype
Free Avenir alternatives chase Adrian Frutiger's geometric sans: circles that are slightly flattened, a two-storey a, and warmth that Futura never had. Avenir Next is a paid family. Nunito, Poppins, Montserrat, and Manrope are the open faces people actually ship when the license budget is zero.
Poppins is the strictest geometry. Nunito is the roundest. Montserrat is louder at display sizes. Manrope sits between marketing and UI. None of them copy Frutiger's optical corrections on the uppercase G or the tail of Q.

Montserrat

Montserrat is more geometric and bold-leaning than Avenir but works well as a display alternative with similar proportions.
Poppins

Poppins is a strict geometric sans with circular forms, closest to Avenir's geometry but with a more assertive character.
Manrope

Manrope brings geometric clarity with a touch of warmth, similar to Avenir's balance of modern and friendly.
Avenir's o is not a perfect circle. Frutiger flattened it so it would not look wider than the n. The t has a wide crossbar. The lowercase a is two-storey, which is why Avenir reads as text-capable where Futura often does not. If a substitute uses a single-storey a, you have already left Avenir's voice.
Nunito rounds the terminals more than Avenir. Poppins keeps the circles purer and therefore colder. Montserrat's M has splayed legs that Avenir does not. Manrope's apertures are more open, which helps small UI but moves it toward Proxima Nova territory.
Leave when you cannot buy Avenir Next for web, when you need a variable file, or when the brand only used Avenir because a template bundled it. Keep Avenir when the identity was drawn around Next's condensed widths; none of the open substitutes match those widths well.
For a friendly SaaS marketing site, try Manrope or Nunito. For a geometric logo lockup that used to be Avenir Heavy, try Poppins 700 and check the counters at 24px.
Avenir often sat over a serif body in print. On the web, Poppins over Open Sans and Nunito over Source Sans 3 are closer to what teams ship. Preview those pairings instead of stacking two geometrics.
Avenir is one of six paid families with open substitutes in this library. The rest are listed below if your brief named a different default.
