CRM

twenty43.4k★

Twenty is a full-blown CRM built to replace Salesforce. Not a toy. Not a contact list with delusions of grandeur. It handles custom objects, kanban views, email integration, calendar sync, workflow automation, and role-based permissions. The UI borrows from Notion and Linear - clean, fast, modern. Self-hosting runs on Docker with Postgres and Redis. The community is massive and active. You get custom fields, API access, and webhooks on every tier. The AGPL license means the core stays open. Enterprise features like SSO sit behind a commercial license. Alternatives like SuiteCRM and EspoCRM exist but feel dated by comparison. Twenty looks and feels like a product built in 2025, not 2005. The catch: self-hosting requires Postgres plus Redis plus the app server. That is not a weekend project for a solo founder. And at $9/user/month for cloud, the open source tax on ops might make the hosted version the smarter call anyway.

erxes wants to be your entire business operating system. CRM, helpdesk, project management, marketing automation - it bundles what most companies stitch together from HubSpot, Zendesk, and Linear into one self-hosted platform. The plugin architecture is genuinely flexible. Pick what you need, skip what you do not. GraphQL federation under the hood means the pieces talk to each other without turning into a monolith. The community core covers sales pipelines, contacts, inbox, segments, and automations. That is a real CRM out of the box. Compare that to SuiteCRM or Twenty, which focus narrower. erxes swings wider - more like an open source Salesforce than a simple contact tracker. The catch: the best plugins are Enterprise Edition only. Accounting, content management, team tools, and several vertical modules sit behind a commercial license. Self-hosting requires MongoDB, Redis, and a microservices stack that will keep your ops team busy. The experience operating system ambition means complexity is baked in from day one.
