Twenty — an open-source modern CRM. Salesforce / HubSpot alternative with developer-first ergonomics and a polished, Linear-feel UI.

What it is

A TypeScript CRM that manages the standard sales surface — companies, people, deals, activities, tasks — with a UX that feels closer to Linear or Notion than to Salesforce. Self-hostable via Docker; commercial cloud at twenty.com. Built around a clean GraphQL + REST API surface so custom integrations don't need to fight a legacy schema. AGPL-3.0 licensed.

Key features

Standard CRM objects: companies, people, deals, activities, tasks, notes.
Custom objects + custom fields without leaving the admin UI.
GraphQL + REST APIs auto-generated against your schema.
Kanban, table, gallery, and detail views per object.
Workflows (automation triggers) for status changes, follow-ups, integrations.
Workspaces with role-based permissions.
Self-host via Docker or use Twenty Cloud (managed offering).
Polished, Linear-style UI — significantly less "enterprise-y" than Salesforce / HubSpot.
AGPL-3.0 licensed.

Tech stack

TypeScript primary across frontend + backend.
NestJS on the backend with Apollo for GraphQL.
React + Recoil/Jotai on the frontend.
Postgres for persistence + Redis for queues / caching.
Docker Compose for local dev + production deploy.

When to reach for it

You want a CRM with modern DX and don't need Salesforce's massive integration ecosystem.
You need self-hosting for data-residency / compliance reasons.
You want the GraphQL API to ship custom integrations without wrestling a legacy SOAP / REST surface.
Your team likes Linear's UX and wants the same feel in CRM tooling.

When not to reach for it

You're allergic to AGPL — the copyleft pulls SaaS hosting into source-release obligations.
You need the broad Salesforce / HubSpot integration ecosystem (AppExchange, Zapier-anchor for CRM, deep Microsoft Office integration).
You want vendor-supported with enterprise SLAs at scale.

Maturity signal

Actively maintained under Twenty PBC. The Y Combinator-backed company funds ongoing development. CRM is a mature product category; differentiation is mostly UX + DX, both of which Twenty invests in. Self-hosting + commercial cloud signals the standard commercial-OSS playbook.

Alternatives

Salesforce, HubSpot, Pipedrive — commercial managed.
EspoCRM, SuiteCRM — older OSS CRMs with deeper ecosystems but dated UX.
Attio — modern commercial alternative with similar UX philosophy but closed-source.
Notion / Airtable with custom views — for very small teams.

Notes

The "modern UX in a CRM" framing is the product's most-distinctive claim — most OSS CRMs (EspoCRM, SuiteCRM) inherit the 2010s-era enterprise look. Twenty pairs that UX with a code-quality backend (NestJS + Postgres + GraphQL) rather than the PHP/MySQL stack typical of older OSS CRMs. AGPL means commercial hosting requires source release; that's intentional and protects the Twenty Cloud commercial offering.
