- Which platforms support Stories?
- Instagram and Facebook support Stories as a distinct post type. Threads, Bluesky, LinkedIn, Pinterest and Telegram have no Stories format at all, and X, TikTok and YouTube do not expose Stories through their publishing APIs either.
- Which platforms support polls?
- X and LinkedIn support polls through their publishing APIs. Instagram, Facebook, TikTok, YouTube, Threads, Pinterest, Bluesky and Telegram do not offer a poll post type through their APIs.
- Which platforms support a genuine carousel post?
- Instagram, LinkedIn, Threads, Pinterest and TikTok (as a photo post) all support a multi-item carousel, each with its own item-count ceiling, from Pinterest’s 5 images up to TikTok’s 35.
- Which platforms let you schedule natively, on the platform itself?
- Facebook and YouTube are the only two platforms with a genuine native scheduling window; every other platform in this matrix relies on a third-party scheduler like SkedCast to fire the post at the right time.
- Do any platforms support document or PDF posts?
- LinkedIn and Telegram both support document attachments — PDF, DOCX and PPTX on LinkedIn, and any file type on Telegram. The other 8 platforms in this matrix do not support document posts.
- Which platforms support a first-comment feature?
- Most platforms in this matrix support an automatic first comment after publish, including X, LinkedIn, Facebook, Instagram, YouTube, Threads, Bluesky and Telegram — Pinterest and TikTok do not offer it.
- Is this matrix the same as what each platform allows natively?
- Not always — it reflects what SkedCast can publish through each platform’s official publishing API today, which can be narrower than what you can do manually inside that platform’s own app.
