BurnSub vs Kapwing
Kapwing watermarks free output , forces uploads to their servers , and requires an account. BurnSub doesn't do any of that.

How BurnSub fixes what Kapwing broke
- ✓ No watermark, no signup, no Pro tier
- ✓ Unlimited free duration — 4-min Kapwing cap is gone
- ✓ 4K input on the free tier
- ✓ No upload — Kapwing forces a 250 MB cap because of their server costs
- ✓ Captions generated locally with Whisper, not server-queued
Real user complaints about Kapwing
"Kapwing watermark ruins my finished video — I have to pay $24 to remove it"
"4 minutes is enough for a tweet but not for a podcast clip"
"Why does Kapwing make me upload a 1GB file when my computer can do this"
Paraphrased from public Reddit / X / forum discussions about Kapwing's free tier. Kapwing isn't a bad tool — but its free tier is built to push you to Pro, not to be useful.
Why Kapwing watermarks (the honest answer)
Started as a meme-maker, scaled into a Pro-tier SaaS. Free tier exists to demo features, not deliver them.
Why BurnSub doesn't need to
BurnSub is a single solo-built web tool. It runs entirely on your hardware (WebCodecs + Whisper-Turbo via WebGPU). There are no GPU server costs, no VC investors expecting an enterprise SaaS exit, and no Pro tier to gate. The site is funded by a tasteful AdSense slot at the bottom of the page — that's it.
