Twenty
Twenty is an open-source CRM and a modern alternative to Salesforce. It auto-generates both a REST API and a GraphQL API from your workspace data model, exposing a Core API for records (People, Companies, Opportunities, Notes, Tasks, and custom objects) and a Metadata API for schema (objects, fields, and relations). Twenty is free to self-host and available as a managed Twenty Cloud offering.
Twenty publishes 7 APIs on the APIs.io network, including Companies API, Metadata - Fields API, Metadata - Objects API, and 4 more. Tagged areas include CRM, Open-Source, Sales, GraphQL, and REST.
Twenty’s developer surface includes authentication, documentation, and 9 more developer resources.
