TranscriptYT vs. Supadata
Supadata is a broader content-extraction API covering YouTube, TikTok, Instagram, X, and general web pages, with an AI fallback for videos that lack a caption track. TranscriptYT is scoped to one job: public YouTube captions, done well.
| YouTube Transcript API | Supadata | |
|---|---|---|
| Scope | YouTube captions only | YouTube, TikTok, Instagram, X, and web content |
| Output formats | JSON, text, SRT, VTT | JSON / plain text |
| No-caption videos | Reports no caption track available | Optional AI transcription fallback |
| Free tier | 100 transcripts, one time | 100 credits / month |
| Entry price | Free tier, paid plans scale from there | Paid plans from $5/mo |
When Supadata is the better fit
If your product needs transcript or content data from several platforms — not just YouTube — a single multi-platform API reduces integration work. Supadata's AI fallback is also useful if you need a best-effort transcript even when no caption track exists.
When TranscriptYT is the better fit
If YouTube is your only source, a focused API is easier to reason about: one response shape, one set of edge cases, and native SRT/VTT export without a conversion step. We only return captions YouTube already publishes — no synthetic transcription — so what you get is traceable back to an existing public caption track.
The short version
Building a multi-platform content pipeline? Supadata's breadth helps. Building specifically on YouTube captions? A focused API keeps the integration simpler.
