Supply Index v1
What the software being built actually looks like
Most measurement of the software economy asks what people use. This asks what gets made. For each of the nine markets in the index, how common a price posture is inside that market, divided by how common it is across the whole catalog.
Catalog as of 13 Aug · 21:25 UTC · 199,443 listings counted of 214,707 visible · every figure computed, none written by hand
In Developer Tools, open source software is 5.39× as common as across the index as a whole — 9,892 listings. In Business & Operations, it is enterprise only that runs at 5.03×. Two markets, two opposite answers to the same question about who pays.
The number in each cell is observed ÷ expected. 1.00 means a posture is exactly as common inside that market as across the index. 2.00 means twice as common. It is a ratio of two shares, so it carries no units and does not move merely because the catalog grew.

Rows are the nine markets, ordered by size; columns are the postures, ordered by how common each one is across the whole index. Each cell carries the index, a bar for how far it sits from parity in either direction, and the number of listings it was computed from. A dash means the cell holds fewer than 50 listings: the count still prints, because it is a real observation, but the ratio does not, because a ratio built on a handful of rows swings on noise and would be read as a finding.
Take the table
The full table — every market, every posture, counts and shares as well as the index — is one file. Take it, check it, republish it; attribution to PulseGate is all we ask.
Edition: 2026-W33 · live. One is taken every week and never rewritten afterwards, so a figure quoted from an edition resolves to that figure for good. The archive begins at the first capture — there are deliberately no earlier editions, because the catalog holds no record of what it looked like before we started taking them, and computing one from today’s rows under a past date would be an invention.
What this number is a fact about
It is a fact about our classification, not about the world. Price posture is assigned when a listing is indexed, from its public pricing surface, and the error rate of that assignment has not been measured yet. When it has, that figure will be printed here.
The ratio cancels sourcing bias that is spread evenly across markets. It does not cancel bias that is correlated with the market itself — so the open-source figure in developer tooling is the single least trustworthy cell in the table, because code hosts are where we look and open source is what lives there by definition. The enterprise figure in business software has no such explanation available to it.
There is deliberately no time axis inside an edition. We know when we indexed a listing; that is not when the software shipped, and drawing one as the other would produce a chart of our own crawler rather than of the world. Ship dates backed by hard evidence exist for a small minority of the index, and a series built on them is a separate publication with its own denominator — not a column added to this one. The weekly editions are a record of this measurement over time, which is a different claim and a smaller one.
15,264 visible listings are not counted above: they carry no price posture, or sit outside the nine markets. They are excluded from both halves of every ratio, never from the denominator alone. See how a listing gets here for the steps before this table.
