Short answer: they are close in shape. Pick Supadata if you need X or Facebook today, web scraping in the same account, or its Make and Zapier apps. Pick Transcript Dock if you want subtitle exports (SRT, VTT), signed webhooks, batches on every paid plan, and an API built around idempotent jobs with typed errors.

When Supadata is the better fit#
- You need X or Facebook transcripts now.
- You also scrape or crawl web pages and want one bill.
- Your team builds in Make or Zapier and wants a native app.
- You need under 300 credits a month and can pay yearly: $5 a month is cheaper than any Transcript Dock plan.
When Transcript Dock is the better fit#
- You ship subtitles: every transcript exports to SRT and VTT for free, as many times as you like.
- You run pipelines: batches and signed webhooks replace polling, and an Idempotency-Key makes retries safe.
- You handle errors in code: every failure has a typed code, such as NO_CAPTIONS or SOURCE_PRIVATE, with a retryable flag. See error codes.
- You want TikTok profile listing and YouTube channel and playlist listing in the same API as transcripts.
- You want Claude to read videos: the Claude connector signs in with your account, no key to paste.
