Twenty vs Frappe CRM
Pick Twenty if your team writes code and wants a Notion-like CRM whose objects, fields and views you define and version as code, with a GraphQL API on PostgreSQL; it measured about 2.2 GB idle and rates 3 / 5 to deploy. Pick Frappe CRM if you need built-in Twilio and Exotel calling, WhatsApp messaging or a path to ERPNext invoicing and accounting, and can accept a 4 / 5 install on the Frappe and MariaDB stack.
Side by side
Twenty and Frappe CRM are both open-source, AGPL-3.0 CRMs you can run on your own server as alternatives to Salesforce and HubSpot, and both ask for about 2 GB of RAM by our estimate. They come from different worlds. Twenty is a young, developer-minded CRM with a Notion-like interface that treats the CRM as code you extend. Frappe CRM is a sales app built on the Frappe framework, the same platform as ERPNext, and its strengths are telephony, messaging and an ERP next door. The install effort is the other big gap: we rate Twenty 3 out of 5 and Frappe CRM 4 out of 5.
Two philosophies
Twenty is TypeScript, with a NestJS back end, a React front end and PostgreSQL. Its README pitches "the CRM you build, ship, and version like the rest of your stack": objects, views, workflows and agents are building blocks, and you define your own objects and fields as code with its SDK and CLI. It exposes a GraphQL API and its data model is customisable without code. It is the pick for a team with engineers who want the CRM to behave like a codebase.
Frappe CRM is Python on the Frappe framework with a Vue interface built on Frappe UI. Its README describes a CRM for modern sales teams with unlimited users and lists an all-in-one lead and deal page that gathers activity, comments, notes and tasks, a drag-and-drop Kanban view, and custom views with filters, sorting and columns. Extensibility comes from Frappe framework customisation and custom views rather than from a code-first SDK.
Integrations
This is where Frappe CRM is clearly ahead. Its README lists built-in Twilio and Exotel integrations for making, receiving and recording calls, WhatsApp messaging through the Frappe WhatsApp app, and ERPNext integration to add invoicing and accounting. If your sales team works on the phone, or you already use or plan to use ERPNext, that is a concrete reason to choose it.
Twenty's README leads with the platform instead of a list of connectors: apps, workflows and agents you write yourself. Twenty exposes a GraphQL API.
Install and footprint
Twenty's official Docker Compose is a server, a worker, PostgreSQL and Redis. In our install the first boot ran a long series of database migrations and the server reported unhealthy until they finished, so the worker had to be started afterwards. It measured about 2.2 GB of RAM idle on our GCP test box, above its 2 GB estimate.
Frappe CRM's catalog install uses upstream's Docker files, which provision a site
alongside MariaDB and Redis. Upstream's README
files this under development: the default login is Administrator with the password
admin. For production it points to an easy-install script that wants a domain
and an email address. We have not measured its RAM. Treat the 2 GB figure as an
estimate, and expect the MariaDB, Redis and web processes to share it.
Which to choose
Choose Twenty if your team can write code and wants a CRM modelled as objects you define and version, with a GraphQL API, on PostgreSQL. Budget more than 2 GB and a patient first boot.
Choose Frappe CRM if you need built-in calling and WhatsApp, want a path to ERPNext, or already run Frappe apps, and you can accept the harder install and a less code-first extension story.

Common questions
Twenty vs Frappe CRM: which self-hosted CRM should I pick?
Pick Twenty if your team can write code and wants a CRM defined as objects and views you version like the rest of your stack, with a GraphQL API. Pick Frappe CRM if you need built-in calling through Twilio or Exotel, WhatsApp messaging, or an ERPNext integration, and can handle a harder install.
Are Twenty and Frappe CRM both open source?
Both are listed under AGPL-3.0 in our catalog. Frappe CRM is built on the Frappe framework, the same platform as ERPNext, and Twenty is a TypeScript application on PostgreSQL.
Does Frappe CRM integrate with ERPNext?
Yes. Frappe CRM's README lists ERPNext as an integration that extends the CRM with invoicing, accounting and more. It also lists built-in Twilio and Exotel call integrations and WhatsApp through the Frappe WhatsApp app.
How much RAM do Twenty and Frappe CRM need?
Neither project's README states a requirement; our 2 GB for each is an estimate. Twenty measured about 2.2 GB idle on our GCP e2-standard-2 test box on 2026-09-28. We have not measured Frappe CRM.
Why is Twenty rated 3 / 5 and Frappe CRM 4 / 5 to deploy?
Twenty needs a long first-boot migration and a worker started afterwards. Frappe CRM's upstream Docker files are aimed at development, with a default Administrator login, and its production route is a separate script that needs a domain and email address.
