Scan intervals, pausing and historical backfill

How often SnitchFeed scans X, LinkedIn and Hacker News for each listener, what scans cost in credits, how pausing works and what historical backfill fetches.

Last updated

SnitchFeed collects posts in two ways:

  • Real time: Reddit and Bluesky. New posts are matched against your terms as they are published. There is no interval to set and no scan cost.
  • Scheduled scans: X (Twitter), LinkedIn and Hacker News. SnitchFeed searches each platform for each term on a schedule you choose per listener, and each scan uses credits.

Set the scan interval

Open a listener and select Scan Intervals. There is one card per scheduled platform (Twitter, LinkedIn and Hacker News). A card is Active when at least one term has that platform turned on, or, for X and LinkedIn, when the listener tracks a profile on it.

Pick an interval from the card's menu and click Save at the top of the editor. The interval applies to every term on this listener for that platform.

Defaults for a new listener:

PlatformDefault interval
XEvery 4 hours
LinkedInEvery 12 hours
Hacker NewsEvery 6 hours

Shorter intervals find mentions sooner. Longer intervals use fewer credits.

What scans cost

Each scan of one term on one platform costs:

PlatformCredits per scan
X2
LinkedIn4, multiplied by the number of author job titles on the term (when it has any)
Hacker News2

Tracked profiles are fetched on the same X or LinkedIn interval: 2 credits per X profile and 4 per LinkedIn profile.

Monthly estimate for one platform:

credits ≈ (24 ÷ scan interval in hours) × 30 × number of terms × credits per scan

Worked example: a listener has 2 terms. Both run on X every 4 hours, and both run on LinkedIn every 12 hours with no job title filter.

  • X: (24 ÷ 4) × 30 × 2 × 2 = 720 credits per month
  • LinkedIn: (24 ÷ 12) × 30 × 2 × 4 = 480 credits per month
  • Total for scans: 1,200 credits per month

Each card shows the estimate for its platform, and the Required credits/mo box under the section list shows the total for the listener. These estimates cover scans only. AI scoring of each stored mention is charged on top. See Credits and usage.

When your workspace runs out of credits, scans and real-time matching stop until credits are available again. See Plans, billing and credit top-ups.

Pause and resume a listener

Pause a listener to stop collecting without deleting it. Open the listener in Listeners and click Paused next to Save. Click Active to resume. The change applies right away, without saving the listener. These buttons appear on saved listeners only.

While a listener is paused:

  • No scans run and no credits are used for its terms or tracked profiles.
  • Reddit and Bluesky posts published during the pause are not collected.
  • Its terms and tracked profiles still count toward your plan's keyword limit, and the listener still counts toward your listener limit.
  • Existing mentions stay in your feeds.

When you resume, SnitchFeed checks each X, LinkedIn and Hacker News term and scans right away if its interval has passed since the last scan. Resuming does not start a historical backfill.

Historical backfill

So a new listener does not start empty, SnitchFeed fetches recent posts for each term once. This runs when:

  • you create a listener (every term),
  • you add a term to a listener,
  • you change a term's query, Whole word or Case sensitive setting, or
  • you turn on Reddit, X, LinkedIn or Hacker News for an existing term (that platform only).

What each platform fetches, per term:

PlatformWhat is fetchedCost
RedditMatching posts and comments from the last 14 days, up to 50 posts and 50 commentsNo search cost
XOne search of recent posts2 credits
LinkedInUp to 2 pages of recent posts, for each author job title4 credits per page
Hacker NewsMatching posts, up to 2002 credits
BlueskyNo backfill

Every backfilled post that is stored as a mention is scored and charged the normal AI scoring cost. If your workspace is out of credits, the backfill is skipped.

Backfilled mentions and alerts

Backfilled mentions appear in your feeds like any other mention. Feed notifications cover mentions that arrive after you set them up. See Set up notifications for a feed.
