Stream to Twitch from your browser

Twitch takes video over WebRTC (WHIP), which every modern browser can send. So a browser tab can be a whole streaming studio: flint puts your camera, screen, overlays and sound together and sends them straight to Twitch.

Going live, step by step

1. Open flint.cam and allow your camera and microphone.
2. Pick what you stream (just chatting, gaming, music, DJ, podcast, IRL) and a look: flint builds Starting soon, Live, Be right back and Ending scenes for you.
3. Sign in with Twitch: your stream key fills itself in. (Or paste it from Twitch's Creator Dashboard › Settings › Stream.)
4. Press Test stream to watch exactly what Twitch would get, in a tab of your own, without going live.
5. Press Go live. Switch scenes with a click, the number keys, a Stream Deck or your phone.

Picture quality

flint uses your graphics card to encode H.264 where the browser allows it, choosing the quality of every frame itself so dark gradients and still scenes stay sharp at Twitch's bitrates. Settings › Video & recording › Test my upload measures your connection and picks the resolution, frame rate and bitrate for you. Twitch's own limit is 6000 kbps, and flint warns you if you ask for more.

Gaming from a browser

Share a game's window or the whole screen as a source; on Windows and ChromeOS the screen's sound comes too. For a console, a capture card shows up as a camera. Your game keeps running at full speed in its own window while the flint tab streams in the background: its frame timer keeps going when the tab is hidden.

Questions

Do I need OBS or Streamlabs?

No. flint does the scenes, the mixing, the alerts and the encoding in the browser and sends the result straight to Twitch.

Is streaming from a browser lower quality?

Not necessarily: flint encodes on your graphics card where it can and steers the quality frame by frame. Your upload speed matters far more than the software.

Can I stream to YouTube or Kick too?

flint streams to Twitch and to any service that accepts WHIP, several at once if you like.

Guides

• Connect Twitch: Sign in with Twitch, or paste your stream key.
• Going live and ending: The Go live button, title and category, and what to keep open.
• Test without going live: Stream to a viewer tab on your own computer, exactly as Twitch would receive it.
• Video size, frame rate and bitrate: What 720p, 1080p, 30/60 fps and kbps mean, and what to pick.
• Share a game or your screen, step by step: What to pick in the browser's picker, and how to get the game's sound.
• Twitch refuses the stream: The key is wrong or old, or the account can't stream yet.
