Crela

Crela is a marketplace for desktop software from independent creators, operated by Crela UG (haftungsbeschränkt) of Kolbermoor, Germany. Buyers purchase tools, apps and games once and keep them, running everything from a single launcher; every build passes a 12-stage review (malware scanning, dependency vulnerability checks, static binary analysis and an AI review) before listing. Creators can publish from coding agents through the local @crela/mcp MCP server or a REST API for listing, build precheck, submission, presigned upload and review status.

Crela is listed with 1 API on the APIs.io network. Tagged areas include Company, Software Marketplace, Desktop Software, Independent Creators, and Software Distribution.

The Crela catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Crela’s developer surface includes CLI, authentication, documentation, API reference, getting-started guide, engineering blog, signup flow, and 31 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/crela-io/apis.yml: open an issue on github.com/api-evangelist/crela-io to ask a question or point us at an artifact you publish.
