Open-source HighLevel alternatives

SuiteCRM is an open-source customer relationship management application for businesses that want control over their data and the freedom to customize their CRM. Its module list covers accounts, contacts, leads, opportunities, quotes, contracts, cases, documents, reports and workflow automation, and it supports multiple languages and currencies.

The README separates two generations of the product. SuiteCRM 7 is described as a mature and stable line with a large community and regular releases of features, security patches and fixes, while SuiteCRM 8 is the newer version that was still catching up on features at the time of writing. The project also maintains an extensions directory, a demo, a community forum and a partner network. It is written in PHP.

SuiteCRM is licensed under AGPL-3.0 and is usually installed on your own web server with a database. Managed hosting and support are available through the vendor and partners. It suits small and mid-sized businesses and agencies that want an open-source alternative to commercial CRMs.

EspoCRM is a free, open-source customer relationship management platform that helps organizations store and manage leads, contacts, sales opportunities, marketing campaigns, and support cases in one web application. The project is released under the AGPL-3.0 license and has been developed since 2014.

The front end is a single-page application backed by a REST API written in PHP, which makes it easy to integrate with other systems. Its feature areas cover sales automation, email marketing, a calendar, kanban views, documents, a customer portal, and customer-support case handling. The data model can be customized to match different business processes.

EspoCRM runs on your own server with PHP 8.3 to 8.5 and MySQL 8, MariaDB 10.6 or later, or PostgreSQL 15 or later. An online demo is available for evaluation. It suits small and mid-sized organizations that want a configurable CRM they can host and modify themselves, and the vendor also sells paid extensions and hosting.

wacrm is a CRM template built around WhatsApp that you can fork, brand, and host yourself. It is built with Next.js and TypeScript and uses Supabase for its backend, according to its topics. The repository is the product itself, while the marketing site and self-hosting documentation live in a separate repository. It is released under the MIT license.

Out of the box it provides a shared inbox on the official WhatsApp Business API, so several agents can work one number with per-conversation assignment, status, and notes. Contacts support tags, custom fields, CSV import, and deduplication. Sales pipelines are shown as Kanban boards with deals linked to conversations, broadcasts use Meta-approved templates with delivery and read tracking and per-recipient variables, and no-code automations trigger on inbound messages.

The project is young, created in 2026, and relies on the WhatsApp Business platform, so using it requires access to the API and compliance with Meta's rules. It suits small businesses, agencies, and developers who want a white-label WhatsApp CRM base.

Django-CRM is a free, open-source customer relationship management application written in Python on the Django framework. It is meant for businesses of any size or freelancers who want a self-hosted CRM with task management, mailing and analytics in one customizable platform instead of a separate SaaS tool for each job.

Core features include lead management, deal tracking and forecasting, company and contact management and role-based access control. For collaboration it adds a task manager with projects and subtasks, reminders, files and internal chat, and for marketing it provides mailing with SMTP and IMAP support, CRM email integration and email campaigns. Built-in analytics and reports cover sales and customer segments. The whole interface runs on Django Admin, with no proprietary UI layer, which makes customization and upgrades predictable.

The project describes its status as production and stable, used in real business environments for many years. It is licensed under AGPL-3.0, suits on-premises installations, and the README is available in many languages.
