Twenty

Twenty is a web-based, open-source CRM for growing B2B sales and customer support teams that need contact management, pipeline tracking, and automation without vendor lock-in.

Key capabilities include:

• Customer data import and storage to bring large datasets into a central system of record for accounts and contacts
• Custom data model with configurable objects and fields, plus permissions to control user access
• Sales pipeline and deal tracking with lead and opportunity management, task tracking, and CRM views (including kanban-style workflows)
• Automation and integrations using REST and GraphQL APIs plus webhooks (integration support such as Zapier and email integration is available)

Pricing: Paid, with a Pro plan at $9/user/month (unlimited records, custom objects/fields, APIs/webhooks, email integration). A Starter plan at $9/seat/month is also mentioned.

Notable for being GPL-licensed and suitable for self-hosting, giving teams the flexibility to modify the CRM for specific workflows while still offering a SaaS-like product experience and developer-friendly integration options.
