How we score →Twenty is the #1 open-source CRM engineered for technical teams that need a fully customizable platform. Unlike traditional CRMs, it combines a full-featured record system (contacts, deals, companies, tasks) with a developer toolkit that includes git-based version control, custom layouts, and AI agents. This allows teams to model data, define business logic, and design UIs using either no-code settings or code-first via CLI, API, and SDK. The platform's standout is its version-controlled workspace: you can branch, PR, review, and rollback changes just like software code, making it ideal for iterative, complex business processes. Key features include custom objects/fields/views, AI agents that write emails and enrich records, rich text widgets in layouts, email thread viewing with inline reply composer, and workflow automation with stop/run controls. Twenty also offers row-level permissions, SAML/OIDC SSO, audit logs, and custom domains on the Organization plan. The latest v2.0.0 introduces the Apps framework for building full extensions with React components, server-side logic, and AI skills. Twenty is built for organizations tired of rigid SaaS CRMs. It is open-source (self-hostable) and available as a managed cloud. For developers and engineering-led companies, it provides unlimited customization without lock-in. However, non-technical users will find the learning curve steeper than Salesforce or HubSpot, and the self-hosted route requires infrastructure know-how.
Twenty is the CRM for teams that treat their internal tools as software—not configuration. If your organization's sales processes evolve faster than your CRM can adapt, Twenty's code-driven approach is a relief. The git-backed version control means you can experiment without fear; rollbacks and code reviews become part of your CRM workflow. The AI agent capabilities, while still maturing, are a preview of where CRM automation is headed. When should you pick Twenty? When you have developers who can write TypeScript, when you need custom objects beyond what Salesforce allows without add-ons, and when you want to avoid vendor lock-in. It's also a strong fit for startups iterating on their data model daily. When should you pass? If your team expects a plug-and-play CRM with a polished UI out of the box, or if you need deep integrations with Salesforce's AppExchange ecosystem. Twenty's third-party integrations are limited to Gmail, Outlook, Slack, and Google Calendar—you'll likely need to build custom connectors via API. Compared to HubSpot or Salesforce, Twenty offers far more flexibility at a fraction of the cost, but the self-hosted version requires DevOps maintenance. The cloud version ($9/user/month for Pro) is cheaper than most, but you give up some of the control that makes Twenty attractive in the first place. Where it bites: the learning curve for non-technical users is steep. Custom layouts and workflows require understanding concepts like git branches and TypeScript objects. Documentation is improving but still incomplete in places. And while the community is active on GitHub, enterprise support is limited to email and chat on the Organization plan.
