Twenty

Twenty is an open-source customer relationship management system built as a community-driven alternative to established CRMs like Salesforce. It pairs a fast, clean interface influenced by tools like Notion and Linear with a flexible data model: users can define custom objects, fields, and views from the settings screen without code, so the CRM can be shaped around a company's actual sales or operations process rather than forcing work into fixed contact and deal records. Twenty runs on PostgreSQL and exposes both REST and GraphQL APIs, and it includes features such as kanban and table views, pipeline management, activity and email tracking, notes and tasks, permissions, and no-code workflow automation. The core project is licensed under a copyleft open-source license, and the community edition includes unlimited custom objects and automations; enterprise capabilities such as single sign-on and advanced role-based access control are reserved for paid tiers. Companies can self-host Twenty to keep full control of their data and infrastructure, or use the managed cloud for a zero-operations setup. It is aimed at startups and small-to-medium teams that want an affordable, customizable, and transparent CRM they can extend, and it has built an active contributor community since launching publicly.
