Tidelift

Tidelift provides open-source software supply-chain management for enterprises. Its platform combines package intelligence (maintenance, quality, end-of-life, and vulnerability signals) with catalogs of approved dependencies, policy and license standards enforcement, SBOM import/export, and "alignment" of projects against an organization's standards. Tidelift is distinctive for paying the open-source maintainers ("lifters") behind the packages enterprises rely on. The Tidelift External API (OpenAPI 3.0, Bearer API-key auth) exposes catalogs, violations, projects, groups, packages, releases, vulnerabilities, licenses, and reporting. Tidelift was acquired by Sonar in 2025; the API and developer surface remain active.

Tidelift publishes 15 APIs on the APIs.io network, including Alignments API, Attestations API, Authentication API, and 12 more. Tagged areas include Company, Open-Source, Software Supply Chain, Dependency Management, and Application Security.

The Tidelift catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Tidelift’s developer surface includes documentation, API reference, getting-started guide, support, pricing, authentication, CLI, and 23 more developer resources.
