The Whatnot streaming setup: from phone-only to a pro OBS rig
Whatnot officially supports streaming from a computer with OBS. The gear that makes a selling stream convert: face cam, product cam, glare-free light, and a wired line.
1080p30 is your platform's practical ceiling. YouTube or Kick allow higher than Twitch standard.

Whatnot is the biggest live-selling marketplace in the US by a wide margin, and most sellers still stream it from a phone propped on a cup. That is exactly why a real setup stands out: buyers stay longer and bid more when they can actually see the item. Here is the ladder from phone-only to a full OBS rig.

The two-camera principle
Selling streams need two views: your face, because people buy from people, and the product, close enough to read a serial number or judge card corners. In OBS that is a webcam for you and a second camera for the goods, switched with one tap. Many sellers use their phone as the product cam inside OBS, which is free and works well.
Face cam pick: sharp 4K and strong low light, and Whatnot itself lists it in its production guide.
A gimbal webcam that can reframe and punch in on the product without you touching it.
Light for honesty, not vibes
Gaming streams light for mood. Selling streams light for truth: buyers need colors that read accurately and no glare hiding a scratch. Soft, even light from two sides kills the hotspot that chrome cards and foil packaging throw. This is the cheapest conversion upgrade on this page.
A soft key light that makes product colors read true on camera.
What Whatnot costs you
Selling on Whatnot means an application (they vet what you sell, with stricter checks for luxury and graded cards), then 8 percent commission plus 2.9 percent and 30 cents per transaction in most categories. Factor it into your pricing before your first show.
