Best Free & Open Source Alternatives to Zoho CRM

Krayin CRM is a fully open-source customer relationship management platform built on the Laravel framework. It provides a comprehensive suite of tools for managing leads, contacts, companies, and deals, making it suitable for both small businesses and larger enterprises.

Features include customizable pipelines, email integration, activity tracking, role-based access control, and multi-currency support. The platform is built with a modular architecture using Laravel and Vue.js, allowing developers to extend and customise functionality with ease.

Krayin can be self-hosted via Docker or a standard PHP server and supports full data sovereignty. It serves as a capable open-source alternative to commercial CRMs like HubSpot, Salesforce, and Zoho CRM, offering comparable pipeline management and contact tracking features without licensing costs.

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.

Dolibarr is a comprehensive open-source ERP and CRM platform that has been in active development since the early 2000s. It covers the full business lifecycle: contact and lead management, quotations, invoicing, order management, stock tracking, and project management — all in a single, modular web application.

The CRM component includes lead and opportunity tracking, contact history, email actions, and customer segmentation. Its modular architecture means you only activate the features you need, keeping the interface clean. It also supports REST APIs, a marketplace of community-contributed modules, and integrations with payment providers and shipping carriers.

Dolibarr is self-hostable on any LAMP/LEMP stack or via Docker and supports PostgreSQL and MySQL. It serves as a lightweight, all-in-one alternative to platforms like Salesforce, Zoho CRM, and HubSpot — particularly for SMEs and freelancers who want integrated ERP+CRM functionality without ongoing subscription costs.

EspoCRM is a free, open source Customer Relationship Management platform that gives businesses full control over their sales processes, contact management, and customer data. Built with PHP and JavaScript, it runs entirely on your own infrastructure, making it an ideal alternative to cloud-locked CRMs like Salesforce, HubSpot, and Zoho CRM.

Key features include contact, lead, account, and opportunity management, email integration with a built-in email client and marketing campaigns, kanban boards and activity streams for pipeline visibility, calendar, tasks, and meeting scheduling, and a customer portal for external stakeholder access. The platform is highly customizable with custom fields, layouts, and entity types, and exposes a REST API for third-party integrations.

EspoCRM supports self-hosting via Docker or traditional LAMP stacks, giving teams data sovereignty without vendor lock-in. Unlike Salesforce complex pricing tiers or HubSpots restrictive free plan, EspoCRM is fully functional at no cost. A cloud-hosted option is available for those who prefer a managed setup.

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.
