Kickstarter + Indiegogo in one table

Search one theme on both platforms and get a single table back, ranked by the one number that means the same thing on both: backers.

What this is not

This is not an overlap finder. A campaign launches on one platform or the other — they are competitors, and cross-posting is rare. If you are looking for "which projects are on both", the honest answer is almost always "none".

What you get instead is the merged list: everything raising money for your theme, in one place, without having to run two actors and reconcile their field names and currencies yourself.

Why amounts are not added up

Kickstarter reports usd_pledged — already converted. Indiegogo reports whatever currency the campaign chose, and a single results page mixes HK$, $ and €. Summing those, or taking a median across them, produces a number that means nothing.

So every row carries:

Filter on amountComparable before you total anything. The run summary totals only the USD rows and says so.

The verdict is allowed to be "cannot tell"

moreBackersPerProject in the summary reports which platform has more backers per project — but only when the 95% confidence intervals around the two medians do not overlap. When they do, or when either platform returned fewer than 6 projects with a backer count, it reports 判定不能 / cannot tell along with the reason. A per-run sample of a few dozen projects often cannot separate the two, and saying so is more useful than a point estimate that flips next week.

Gamefound

Indiegogo's search results include campaigns hosted on gamefound.com — 7 of 24 in one sample. They are kept (dropping them would understate what the page shows) and labelled

platform: "gamefound"

Input

{
  "term": "board game",
  "state": "live",
  "maxItemsPerPlatform": 24
}

• state applies to Kickstarter only — Indiegogo's explore page has no equivalent filter. Each row carries its own state so you can see what you got.
• Indiegogo serves at most 24 projects per run. Its page parameter is ignored (pages 1, 2 and 3 returned identical results when measured). Raising maxItemsPerPlatform only adds Kickstarter rows.

When one platform fails

The run still returns the other platform's rows, and platformsFailed in the summary names what broke and why. It is never silently reported as zero results. If both fail, the run fails — half a comparison is not a comparison.

Output

One dataset row per project, plus a SEARCH_SUMMARY record: per-platform counts, median backers with a confidence interval, the USD-only total, the Gamefound count, and the verdict above.
