Twenty
Twenty is an open-source CRM platform built as a modern alternative to Salesforce, designed for teams that need flexibility, data ownership, and a contemporary developer experience. It provides REST and GraphQL APIs covering core CRM operations such as managing companies, people, opportunities, notes, tasks, and fully customizable objects. Developers can extend Twenty with custom objects, server-side logic, UI components, and AI agents as TypeScript packages, all surfaced through the same API surface. The platform is available as a cloud service or as a self-hosted deployment via Docker Compose, giving teams full control over their data residency and infrastructure.
Twenty publishes 9 APIs on the APIs.io network, including companies API, fields API, notes API, and 6 more. Tagged areas include CRM, Open Source, REST, GraphQL, and Webhooks.
The Twenty catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Twenty’s developer surface includes authentication, documentation, engineering blog, pricing, and 14 more developer resources.
