vTiger CRM Open Source Extensions
It’s 2026, and although the SaaS version (vTiger.com) has attempted to dominate the market with its 'closed' subscription model, the vTiger CRM Open Source community vTiger CRM Open Source is more alive than ever. For those of us seeking full control, data privacy, and zero rental costs per user, the open-source version remains the crown jewel.
However, for this version to excel, we depend on extension developers. At vTigerSpain , we provide a breakdown of the leading providers who, to this day, keep the vTiger Open Source engine roaring.
1. VTExperts: The 'Extension Pack' Giant
If you are looking to transform a standard vTiger into a productivity beast, vtexperts.com is a mandatory stop. In 2026, they have consolidated their 'Extension Pack' model, where a monthly or annual subscription grants you access to more than 70 modules.
What makes them special? They don’t just create modules; they create experiences.. Their interface design is typically much cleaner than the vTiger standard.
Flagship Modules:
Document Designer: The ultimate tool for creating proposals and contracts with integrated e-signature.
Custom Module Builder: It allows you to create new modules without touching a single line of code.
Email Marketing Automation: A true Mailchimp alternative, fully integrated into your CRM.
Status in 2026: They continue to lead the support for vTiger 8.x and experimental community versions, being the fastest to release their security patches.
2. IT-Solutions4You: Slovak Precision Engineering
If VTExperts is the 'Swiss Army Knife,' it-solutions4you.com is the 'scalpel.' This Slovak provider is renowned for the stability and technical depth of its developments. Their modules are designed for companies managing complex processes and large volumes of data.
What makes them special? Their modules are incredibly robust. If you install something from them, you know it’s not going to break the system.
Flagship Modules:
PDF Maker: It remains, by far, the best engine for generating PDFs in vTiger. It allows for conditional logic within documents (e.g., if the client is from Spain, show this text; if they are from Mexico, show this instead).
Reports 4 You: A reporting engine that far surpasses the native one, allowing for dynamic charts and advanced data cross-referencing.
Dynamic Fields: Essential for hiding or showing fields based on user profiles or record status.
Status in 2026: They maintain impeccable support, and their centralized installer makes license management much easier.
3. VGS (Virtual Global Systems): The 'Ghost' Legacy
Unlike the previous two, VGS no longer operates as an active provider. They vanished from the commercial map a few years ago, but their shadow looms large over the vTiger ecosystem, especially in the Spanish-speaking market.
What did they leave behind? VGS was very popular during the versions 6.X y 7.X. They developed very specific modules for telephony integrations (Asterisk/Vicidial) and UI enhancements that many system administrators still keep on their servers like 'archaeological treasures'.
The situation in 2026: You can still find their modules in old GitHub repositories or community forums.
Security Note: Using VGS modules today requires caution. Since they lack official support, they often present incompatibilities with PHP 8.x (the standard in 2026). If you have a legacy vTiger 7.x instance, you will likely find traces of them, but the current recommendation is to migrate those functionalities to VTExperts developments or custom-built solutions.
