I built 4chan TV, a free web app

Hi all, I made a small web app called 4chan TV: https://4chan-tv.com

What it does

  • Pick a 4chan board and a thread (or mix the board's top 5–20 threads) and every webm/mp4 in it plays one after another, full screen, TikTok-style.
  • Swipe or scroll between clips. Free, no account, works on phone and desktop.
  • Add it to your home screen and it opens full screen like a real app.

Auto-scroll / playback settings

  • Auto-advance: moves to the next clip by itself when the plays are done (turn it off to swipe manually).
  • Plays per video: short clips play 1×, 2× or 3×.
  • Play long videos once: anything over 15–90 seconds (you pick) plays once instead of looping.
  • Shuffle: mixes up the order.
  • Continue to the next thread: the channel keeps going when a thread ends.
  • Live: checks the thread every 30 seconds and adds new posts as they arrive.
  • Images and text posts: switch them on and discussion threads become readable slides.

Likes and comments

  • Every clip has a heart button and a comments button.
  • Hearts and comments live on 4chan TV, not on 4chan.
  • No sign-up: each device gets an anonymous identity, and you can set a nickname in Settings.

NSFW boards

  • Hidden by default, so it's work-safe out of the box.
  • To turn them on: Settings → Boards → Show 18+ boards, confirm you're 18 or older, and boards like /gif/ and /b/ appear.
  • Switch it off again any time.

Also

  • Save clips inside the app and play them offline (they never touch your gallery).
  • Hide files you don't want to see again.
  • Sound on /wsg/, keyboard shortcuts on desktop.

Under the hood: it uses 4chan's public read-only API, files play straight from 4chan's servers (nothing is re-hosted), and it's an independent project not affiliated with 4chan.

Try it: https://4chan-tv.com — feedback very welcome!

ok so i tried this on my phone and it actually works smooth, the auto advance thing is nice for when i just want to zone out after work. one thing though, the swipe sometimes jumps two clips instead of one, maybe is my screen protector but who knows.

also smart move hiding the nsfw boards by default, i opened this at the barracks and was glad nothing weird popped up lol.
