Crowd.dev

Crowd.dev is an open-source developer data platform that centralizes community, product, and commercial data to unify contributor identities, resolve who is engaging with an open-source project, and activate that data for developer relations and community-led growth. Founded in Berlin and backed by Seedcamp, crowd.dev was acquired by the Linux Foundation in April 2024 and now powers the LFX Community Data Platform (CDP). The codebase is Apache-2.0 open source at github.com/CrowdDotDev (now linuxfoundation/crowd.dev), and the CDP Public API exposes transactional REST endpoints for member and organization profiles, identity verification, work-experience and project-affiliation management, contributor affiliation lookups, and open-source package/stewardship intelligence.

Crowd.dev publishes 16 APIs on the APIs.io network, including Advisories API, Affiliations API, Contacts API, and 13 more. Tagged areas include Company, Community, Developer Relations, Developer Data Platform, and Identity Resolution.

Crowd.dev’s developer surface includes authentication, documentation, API reference, changelog, and 19 more developer resources.

    read). Confirm the final scope name (read:advisories vs cdp:advisories:read) with Akrites/product.
