Open-source Redtail CRM 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.
