Self-hosting basics: Twenty, Odoo Community, SuiteCRM and EspoCRM need a server, which can be a small cloud server or a spare machine at home. For a sense of scale, DigitalOcean's price list shows a 1 GiB server at $6/month and 2 GiB at $12/month (checked Oct 29, 2026). Check each project's documented requirements before choosing a size, and budget time for updates and backups.
Don't want to run a server? Twenty, Odoo Community and EspoCRM offer a hosted plan run by the project itself. Prices change, so check each project's site.
License check: Twenty and Odoo Community do not use a single standard open-source license that GitHub can detect. Read the license before using them in a business.

Salesforce alternatives: common questions
What is the best open-source alternative to Salesforce?
It depends on how you use Salesforce. Of the 4 options here, Twenty is the most followed on GitHub (60.1k stars) and is actively maintained, with its latest release on Oct 29, 2026.
Is there a self-hosted Salesforce alternative?
Yes. Twenty, Odoo Community, SuiteCRM and EspoCRM run on a server you control, so your data stays with you. If you'd rather not run a server, Twenty, Odoo Community and EspoCRM also offer a hosted plan from the people who make them.
Is there a free alternative to Salesforce?
Yes. Every project on this page can be downloaded and used at no cost from its public repository. Server apps are free software, but you pay for the server they run on. Check the license of Twenty and Odoo Community before using them in a business.
Are these Salesforce alternatives still maintained?
As of Oct 29, 2026, 4 of 4 had a code push or release in the last 180 days. None are flagged as inactive or archived. We re-check every project weekly.
How much does it cost to switch from Salesforce?
The software itself is free. For server apps, the main cost is hosting: as a reference point, DigitalOcean lists a 1 GiB server at $6/month and a 2 GiB server at $12/month (checked Oct 29, 2026). Check each project's documented requirements before choosing a size. The hidden cost is time: moving your data and, for self-hosted apps, keeping up with updates and backups.
Are all of these really open source?
Not all under a standard license. Twenty: GitHub could not identify a single standard license for this repository (often a mix of open-source and commercial parts). Read the LICENSE file before using it. Odoo Community: Odoo Community is LGPL-3.0; Odoo Enterprise apps are proprietary. The others use OSI-approved open-source licenses.
