Best Open-Source Salesforce Alternatives (2026)
17 self-hostable, open-source projects that replace Salesforce — without notoriously expensive per-seat licensing. Each is scored for how hard it is to self-host, with one-click deploy options where they exist.
Salesforce's per-seat licensing escalates sharply with users and add-on clouds, and much of the platform's real power is gated behind paid modules and integration fees. Teams also leave to own their customer data outright and to escape deep customization lock-in that makes the platform expensive to leave once embedded.

Its CRM is one app in a full ERP suite, giving the broadest feature surface for replacing Salesforce plus adjacent clouds.
A modern Salesforce-focused CRM (3/5 difficulty) that offers managed hosting, lowering the barrier for non-ops teams.

What to look for: Decide whether you want a focused CRM or a full ERP suite, since several options here bundle accounting, inventory, and more. Weigh data ownership and extensibility (custom entities, fields, and APIs), the maturity of the migration/import tooling, and a self-host difficulty your team can actually support, as most options here are 4/5.

The verdict
For most teams replacing Salesforce, Twenty is the best balance: a modern, CRM-first design, 3/5 self-host difficulty, and a managed option. Choose Odoo if you want CRM as part of a full open-source ERP, or EspoCRM if you want a lightweight, fast, easy-to-run standalone CRM.
Salesforce alternatives — frequently asked questions
What is the best open-source alternative to Salesforce?
Twenty is the most direct modern CRM alternative, built specifically as a Salesforce replacement, with 49,900 stars and managed hosting. Odoo is the strongest pick if you want CRM bundled with full ERP capabilities.
Which Salesforce alternative is easiest to self-host?
EspoCRM, Twenty, Frappe CRM, and Atomic CRM are all rated 3/5, the lowest difficulty on this list. Most others (Odoo, Krayin, Dolibarr, SuiteCRM, CiviCRM) are 4/5, and erxes and OroCRM are 5/5.
Is there a free Salesforce alternative with managed hosting?
Yes. Twenty, Odoo, Dolibarr, SuiteCRM, erxes, EspoCRM, Frappe CRM, and OroCRM all offer managed hosting. Twenty and EspoCRM are the easiest to run if you later move to self-hosting.
Which open-source CRM is best for nonprofits?
CiviCRM (AGPL-3.0) is purpose-built for nonprofit constituent relationship management. It is manual-deploy only and rated 4/5 difficulty, so budget for setup effort.
Can I get a full ERP plus CRM, not just sales?
Yes. Odoo and Dolibarr both bundle ERP and CRM. Odoo (LGPL-3.0) is the larger, more feature-rich suite; Dolibarr (GPL-3.0) targets small businesses and is lighter weight.
Which alternatives use a permissive license for commercial use?
Krayin, Atomic CRM, and OroCRM are MIT-licensed. Odoo is LGPL-3.0, and Twenty, SuiteCRM, erxes, EspoCRM, Frappe CRM, and CiviCRM are AGPL-3.0, which adds copyleft obligations if you offer the CRM as a hosted service.
