Best Free & Open Source Alternatives to Pipedrive

Twenty is an open-source CRM built to be customized and extended like the rest of your stack: objects, fields, views, workflows, and AI agents are defined in the product or in code, then versioned and shipped to a workspace.

Out of the box it covers the standard CRM building blocks — companies, people, opportunities, tasks and notes — with a flexible data model for custom objects and fields, saved views, Kanban pipelines, and email and calendar sync for Gmail/Google Calendar and Microsoft 365. The v2 releases add a code-first layer: the Twenty CLI (npx create-twenty-app) scaffolds apps that declare objects and fields in TypeScript, publish them to a workspace, and keep the configuration under version control alongside agents and logic functions. AI agents and chats are part of the product, and GraphQL and REST APIs plus webhooks expose the data model to other systems.

Twenty runs as a hosted cloud service with a free tier, or self-hosted with Docker Compose. A typical deployment needs at least 2 GB of RAM and runs PostgreSQL, Redis, and optional S3-compatible storage for files. Compared with Salesforce, it removes per-seat enterprise licensing and puts the schema and deployment under your control; compared with HubSpot, Pipedrive, and Zoho CRM, it trades a fixed feature set for a customizable, self-hostable codebase. Views, workflows, and permissions have to be recreated when migrating from another CRM, so plan for configuration work on top of the data import.

Comp AI is an open-source, agentic-first CRM built by the team behind trycomp.ai. Most CRMs are a database with a form in front of it; the AI ones bolt a chat box onto the side of that form. Comp AI is built the other way round — the agent is not a feature of the CRM, the CRM is where the agent keeps its notes. It runs on its own deployment, on its own schedule, against its own work queue, deciding what to look at next, booking its own follow-ups, and stopping when the research budget runs out.

The stack is a TypeScript Turborepo monorepo on Bun: a Next.js front end, a NestJS API with tRPC type safety, Prisma on Postgres, and a research agent built on the eve durable-agent framework. The agent ships with 18 tools (read CRM history, search, identify contact, research person, enrich company, record fact, schedule recheck) and 4 skills, runs inside a network-isolated sandbox, and is provider-agnostic via the Vercel AI Gateway.

Comp AI is single-tenant and self-hosted by design. Google sign-in is the only door; an allow-list env var is the entire authorisation model. Mailbox and calendar sync keep deals, contacts, and companies current without a human typing them in, and every outside data source (LinkedIn, web research, company brand data) is optional — the agent works with none of them. It is released under the MIT license and targets internal sales teams that want a self-hostable Salesforce / HubSpot / Pipedrive / Zoho CRM alternative without an AI feature bolted on as an afterthought.

Frappe CRM is a modern, fully open-source CRM built by the team behind ERPNext and the Frappe Framework. It is designed for sales teams that want a fast, uncluttered pipeline tool without per-seat pricing: lead capture, contacts and organizations, deal stages, activity logging, tasks and follow-ups all live in one place.

The UI is a Vue.js single-page app with list, Kanban and grouped views, forecasting dashboards, email templates and role-based permissions. Leads can arrive from web forms, email, WhatsApp Business, Facebook lead ads and phone calls, and the built-in enrichment fills in company details. Twilio and Exotel handle telephony, while an ERPNext integration lets teams create quotations from a deal and turn won deals into customers.

Frappe CRM runs on the Frappe Framework, so fields, statuses, views and layouts can be customized without code, and extended further by developers. It is self-hostable via Docker or Frappe Bench, or available as a managed service on Frappe Cloud — a lean alternative to HubSpot and Pipedrive with no per-user fees and no cloud lock-in.

Relaticle is an open-source CRM platform built with Laravel and Filament, featuring native AI agent support through 30 MCP (Model Context Protocol) tools. It provides a modern, self-hosted alternative to proprietary CRMs with a clean UI and REST API for integrations.

Key features include contact and company management, sales pipeline tracking with opportunities, task management, team collaboration, and note-taking. The built-in AI agents can assist with data entry, lead scoring, and workflow automation directly within the CRM interface.

Designed for teams that want full control over their customer data, Relaticle can be self-hosted via Docker and offers a flexible architecture for custom integrations and extensions. Its progressive web app design ensures accessibility across devices while keeping all data on your own server.
