Methodology

How the numbers on Streamable Charts are produced.

Where does the data come from?
Streamable Charts polls the public Twitch Helix API and the Kick API every hour and records every live channel with its concurrent viewer count, title, category and language. Nothing is estimated or sampled from third parties for live data.
How is hours watched calculated?
Hours watched is the sum of concurrent viewers across every hourly sample while a stream is live: each sample contributes its viewer count multiplied by the time since the stream's previous sample (or since it went live). A stream holding 12,000 viewers for one hour adds 12,000 hours watched.
What are average viewers and peak viewers?
Average viewers is the mean concurrent viewer count over the selected period or stream. Peak viewers is the highest single concurrent viewer count observed in that period.
What is airtime?
Airtime is the total time a channel was live in the period. Short disconnects (a few minutes) are merged into one stream so a dropped connection does not count as two broadcasts.
How do the rankings work?
Channel and game rankings sort by the chosen metric (hours watched by default) over a rolling period of 7, 30, 90 or 365 days, or over a calendar month. Live rankings use the latest poll. Rankings recompute every 6 hours; Free accounts see the top 100 rows and the last 30 days.
Where do follower counts come from?
Follower totals are read from each platform's public profile data and refreshed on a schedule; follower gain for a period is the difference between the first and last reading in that period.
Why does a channel show no data?
A channel only has statistics once it has been live during our collection. Opening a Twitch channel we have never seen triggers an import of its public history; Kick has no equivalent public archive, so Kick channels accrue history from the day they are first tracked.
What does “imported” mean on older months?
Months before our own collection started are imported from publicly visible aggregate statistics (TwitchTracker) and are stored with source = imported so they can be distinguished from data we collected ourselves.
Which platforms are supported?
Twitch and Kick. YouTube, TikTok and Facebook Gaming are not tracked.
How often does the site update?
Live viewer counts update every hour. Daily, monthly and ranking aggregates are recomputed every 6 hours.
