Viral library: short-form posts that took off, with the numbers

Thousands of TikTok, Instagram and YouTube posts that performed far above the norm, each with its hook, cover and the views, likes, comments, shares and saves captured on the snapshot date. Filter by platform, format, category, source, ad signal, language, posting date and minimum views, likes or saves. Subscribers get every page, search, every sort and the slides and videos behind each post.

How to use the library

Start with the format you make. Slideshows and videos behave differently: a slideshow wins on its first frame and its hook, a video on the first two seconds. Filter to one format, then to one category, and read the hooks on the top page before you look at anything else.

Treat the counts as a record of what happened, not a live feed. Every post shows the date its metrics were captured, and a platform that did not report a number shows it as not reported rather than zero. The post itself belongs to its creator: the library links to the original so you can see it in context.

Frequently asked questions

What the library holds, where its numbers come from, and what a subscription adds.

  • What is the viral library?

    A browsable collection of short-form posts that performed unusually well on TikTok, Instagram, YouTube and other platforms. Each entry shows the hook, the caption, a cover image and the engagement counts we captured, and links to the original post.
  • Where do the view and like counts come from?

    Views, likes, comments, shares and saves are as captured on the snapshot date shown with each post. They are a point-in-time record and are not refreshed, so the live numbers on the platform will differ. A count reads "Not reported" when the platform did not expose it.
  • Who owns the posts in the library?

    Every post belongs to its original creator and lives on its original platform. The library shows the cover, the hook, the caption and the captured metrics, and links out to the original. OctoSpark claims no rights over any of this content.
  • What does the free view include?

    The first three pages of the library, ordered by views, with the platform, category and format filters. No account is needed. Signing in with an active OctoSpark subscription opens the full library inside the app.
  • What does a subscription add?

    Every page of the library, full-text search across hooks, captions and creator handles, sorting by likes, saves, publish date and engagement rate, and the slide images and video files we hold for each post. The same data is available through the OctoSpark API, CLI and MCP server.
  • Why am I being asked to slow down?

    The library limits how quickly one visitor can page through it, so it cannot be scraped wholesale. When you see the notice, wait for the countdown and carry on; nothing you were looking at is lost.
