  • Twenty is a free, self-hosted CRM with 44,000+ stars on GitHub, replacing Salesforce and HubSpot for $0.
  • Built by a YC-backed team (S23) with 11,000+ commits and 3,000+ forks — a production-ready CRM, not a side project.
  • AGPL-3.0 licensed with custom objects, kanban views, Gmail and Outlook sync, workflow automation, full API, and webhooks included.
  • A 10-person sales team on Salesforce pays $21,000 a year. The same team on self-hosted Twenty pays the cost of a VPS — about $60 a year.

Why Twenty Is Better Than Salesforce

Salesforce charges $175 per user per month for its Sales Cloud Enterprise tier. HubSpot CRM Suite Professional costs $1,781 per month plus a $4,500 onboarding fee. Even Salesforce Starter sits at $25 per user per month with feature gates everywhere. The real product these companies sell is not the CRM — it is the lock-in. Your data, your workflows, your integrations all live on their servers, and migrating off costs more than staying.

Twenty flips the model. The self-hosted version is free forever — no seat limits, no feature gates, no surprise pricing tiers. You install it on your own server, your data stays on your infrastructure, and every feature ships unlocked: custom objects and fields, kanban boards, table views, filters, grouping, email sync with Gmail and Outlook, workflow automation with triggers and actions, custom roles and permissions, a full REST and GraphQL API, webhooks, and keyboard shortcuts for everything.

Twenty is not for teams that want a managed, hand-held experience with a dedicated success manager. It is for founders, sales leaders, and ops teams who want a modern CRM that they own outright. A 10-person team running Twenty on a $5 Hetzner VPS replaces a Salesforce bill that would cost $21,000 a year — with no seat tax, no migration trap, and no quarterly upsell call.

How to Get Started With Twenty

  1. Spin up a VPS on Hetzner, DigitalOcean, or any provider ($5 per month minimum).
  2. Follow the self-hosting documentation — Docker Compose deploys the full stack in minutes.
  3. Configure Gmail or Outlook OAuth credentials for inbox and calendar sync.
  4. Create your first workspace, custom objects, and import contacts via CSV or API.
  5. Connect Zapier, n8n, or your own scripts via the REST and GraphQL API.
  6. Invite your team — no per-seat license fees, ever.

Twenty has 44,000+ stars, 11,000+ commits, and 3,000+ forks on GitHub. It is built with TypeScript, NestJS, and React, deployed via Docker, AGPL-3.0 licensed, and backed by Y Combinator from the Summer 2023 batch. If you do not want to self-host, the cloud version is $9 per user per month — still cheaper than Salesforce Starter, with more features unlocked.
