Kin Score
What adopting Insomnia moves on the Kin Score 3
Insomnia is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.
Insomnia is a tool a provider’s team works in, not a surface the score reads. A shared Insomnia collection earns nothing: postman_present reads only Postman-typed pointers, and Insomnia exports its own and HAR formats, not Postman’s. It can help a provider that authors its OpenAPI and custom lint rules in Insomnia and publishes them through Git Sync, and a cloud mock can stand in as a sandbox — every one of those is conditional on the provider publishing and declaring the result.
| Check | Earns | Through |
|---|---|---|
| Publishes a machine-readable contractsaturated Contract QualityOnly if the provider authors its OpenAPI in Insomnia and publishes it (Git Sync to a public repo or its own site) — Insomnia is the editor, the contract is the provider’s to publish. |
20.0 of 20 | API Collections with a Spec tab |
| Publishes a rulesetconditional Contract GovernanceOnly if the team writes custom rules and publishes the ruleset file in a public repository the catalog reads — the built-in linting publishes nothing. |
10.0 of 10 | Spec linting with custom rulesets (app and inso lint spec) |
| Console or sandboxconditional Developer ErgonomicsOnly if the provider exposes a mock publicly and declares it as Sandbox; the mock returns the sample responses someone typed, not the API’s behavior. |
3.0 of 3 | Cloud-hosted and self-hosted mock servers |
What Insomnia ships that earns nothing (3)
- API Collections with a Spec tab — The check reads Postman-typed pointers only. Insomnia exports its own and HAR formats; a shared Insomnia collection is not a Postman collection and declaring it as one would be mislabeling.
- Inso CLI — Inso is Kong’s CLI for running collections and linting; it is not a command-line client for the provider’s API.
- MCP clients — Insomnia is an MCP client for testing servers others run; it creates no server for the provider.
A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| GraphQL Ecosystem (Foundation, graphql.org listings, public GraphQL APIs) | standard | 17.2 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 1
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
