Developer Tools
Platform market (extension marketplaces). The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- GitHub Marketplace apps (server-rendered listing JSON, verified domain per app) machine-readable
- GitHub Marketplace actions, verified creators only (unverified actions name a login, not a company) machine-readable
- Atlassian Marketplace REST API (rest/2/addons) with vendor homepages machine-readable
- JetBrains Marketplace API (searchPlugins + plugin vendor) machine-readable
- VS Code Marketplace gallery extensionquery (verified publisher domains) machine-readable
- GitLab project integrations (GitLab-built; no third-party marketplace) machine-readable
- GitHub Marketplace GraphQL marketplaceListings not machine-readable: needs authentication
- Unverified GitHub Actions and VS Code publishers' claimed domains not machine-readable: no verified publisher identity; logged, never linked
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-23 from the 25 providers in this market we could resolve in the catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.

Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.

Top workflows by market votes
Workflows (Arazzo) and their phrasing are generated by API Evangelist, ranked by market votes (integration edges in the graph, weighted by channel).
In-market workflows only: a step on the market provider's side maps to this market's business capabilities (BC-4200, BC-4210, BC-4220, BC-4270, BC-4280), and the partner is not a generic export/notify app. Other workflows are counted as bridges (including any whose steps do not resolve to a capability yet). Methodology. In-market: 1; bridges: 2.
Generated 2026-10-24 from API Evangelist's own files; nothing on this page is a model's judgement. Provisional and unweighted; not part of the Kin Score composite or agent readiness. Read the Market layer methodology. Disagree with an edge? Every edge cites its evidence and can be corrected through the normal correction path.
