Sites today are in a technological arms race to block scrapers. Shoal collects data from real users' browsers by parsing HTML, and intercepting fetch() requests with a browser extension, and sends them to your backend. Bring your own workers for free or pay as you go to hook into our data firehose.
Updates are batched every 5 seconds for each user
Many scraping tools use unsuspecting users or compromised machines as part of their infrastructure. Shoal workers are always fully informed of what they're running on their machine.
We piece together events for you to give you the full picture whenever things change. When you're ready to scale, you only pay the amount of unique data you receive, and get updated on them for free.

Track follower counts and post performance on Instagram and LinkedIn over time. Build the engagement dataset the platforms won't hand you through an API.
Aggregate listings across a whole category to see real pricing, supply, and how fast inventory turns over, sourced from the same pages buyers actually see.
No single page has the whole picture. A feed card gives you a handle and an avatar. A search result adds a follower count. The profile page fills in the rest. Each page your workers pass through reveals a different slice of the same entity.
Shoal keys every observation to its identity and merges them, so the record grows more complete the more angles it's seen from, with no extra requests and no duplicate rows.
