YetiForce

YetiForce is an open-source CRM that began in 2014 as a fork of Vtiger. Its developer is based in Warsaw, Poland. The vendor says the system has more than 80 modules covering marketing, sales, projects, support, finance, logistics, office work and HR. Modules include leads, contacts, accounts, opportunities, quotes, invoicing, and workflows for automating sales processes. The vendor says it is used in about 100 countries and 35 languages, and that its largest installation has more than 12,000 users. That makes it best suited to technically capable small, mid-sized and large organizations that want deep customization, including custom modules, without paying per-seat licence fees. The software itself costs nothing to self-host. The vendor earns money from cloud hosting, Marketplace add-ons and paid support. Cloud plans are priced by company size, not per user. Small costs 80 EUR net per month for up to 19 users. Medium costs 150 EUR for 20 to 49 users. Large costs 540 EUR for 50 or more users on dedicated infrastructure. Enterprise is quoted on request, and paying annually gives a 5 percent discount. The system offers REST web service APIs, documented as Webservice Standard and Premium, plus email integration through a built-in Roundcube-based mail client. The main drawback is the work of running it yourself. Reviewers mention thin documentation, no automatic updates, demanding server requirements, and a reporting tool that is weaker than the rest of the product. Some long-time users also say the vendor has moved key functions behind paid Marketplace add-ons. Most public reviews date from 2015 to 2019. In August 2025 the old GitHub repository was archived and development moved to a new repository.
