Self-hosted alternatives to Salesforce
Implementation consultants often cost more than the licences, and both are permanent.
Below are 10 open-source projects that cover the same ground, each scored 0–100 on how actively it is actually maintained — commit volume, release cadence and recent trend. 8 of the 10 are currently rated healthy or better. Ordering reflects that score, not sponsorship.

How these were picked
Every project listed here is open source and can run entirely on hardware you control. We start from the categories that match Salesforce's job — Customer Relationship Management (CRM), Resource Planning — then rank by health score so that a popular-but-abandoned project never appears above a smaller one that is actively shipping. The scoring method is documented in full.
The scores are recomputed from repository data on every rebuild, so this page reflects the state of these projects as of 1 Oct 2026 — not the day it was written.
Twenty
A modern CRM offering the flexibility of open source, advanced features, and a sleek design.
Best fit: It suits organisations requiring a self-hosted contact management system with full access to the source code and data layer.
Worth knowing: The AGPL-3.0 licence places restrictions on distributing modified versions, which may affect teams building commercial services on top of the codebase. It also faces strong competition from mature proprietary and open-source CRM alternatives.
Dolibarr
Modern CRM software package to manage your company or foundation activity (contacts, suppliers, invoices, orders, stocks, agenda, accounting, ...).
Best fit: Small to medium enterprises or foundations looking for an open-source, monolithic platform to manage internal administration and commercial activities without relying on hosted SaaS tools.
Worth knowing: The GPL-3.0 licence requires that any modified source code be made available if you distribute the software publicly, and monolithic PHP applications can sometimes become difficult to maintain as your customisation needs grow.
Odoo
Free open source ERP system.
Best fit: This software suits teams seeking a comprehensive, self-hosted resource planning suite that they can modify freely.
Worth knowing: Enterprise resource planning platforms typically demand significant configuration effort and administrative overhead to align with specific business workflows.
EspoCRM
CRM with a frontend designed as a single page application, and a REST API.
Best fit: It suits teams that require a self-hosted platform to manage customer interactions and need programmatic access via a REST API. It is also an option if you prefer a single-page application architecture for your CRM.
Worth knowing: You should check the implications of the AGPL-3.0 licence closely if you plan to modify and distribute the software or offer it as a service. It may also require significant configuration to match specific enterprise workflows.
Krayin
CRM solution for SMEs and Enterprises for complete customer lifecycle management.
Best fit: Teams looking for an open-source PHP-based CRM that they can host internally and customise without proprietary vendor lock-in.
Worth knowing: As an enterprise CRM with a broad feature set, it may require significant configuration and ongoing maintenance to align with specific sales workflows compared to simpler alternatives.
