ERP5 vs Tryton

ERP5 is a free, open-source business platform covering CRM, production management, supply chain, product design, accounting, human resources and e-commerce. Its listed modules include finance, inventory, order management and manufacturing, with support for multiple entities. The system can be used and configured in a web browser, and the maker says all browsers are supported. Organizations can also run a preconfigured ERP5 virtual machine on their own server. That VM package is not recommended for large production environments with many users or for development; the maker recommends SlapOS for production deployments and complex integrations. ERP5 is written mostly in Python and uses the NEO transactional NoSQL database alongside a relational SQL database, with MariaDB preferred. It provides a HATEOAS JSON API and an MCP implementation that can expose read-only or read-write services. ERP5 uses role-based permissions configured by module and document. The maker says it is intended for organizations prepared to supervise deployment or learn the platform in depth. ERP5 is free to download and use under GPL v2.

Tryton is modular business software for companies of any size, with tools for accounting, sales, inventory, CRM, purchasing, supply chain, manufacturing, shipping, projects, and subscriptions. It also lists finance, order management, and multi-entity support. Its three-tier architecture uses an application server, a PostgreSQL database, web or desktop clients, and server modules for business logic. Tryton is free and open source, with on-premise self-hosting or third-party hosting; providers also offer rented cloud servers. Desktop clients are available for Windows 64-bit, macOS x86-64 and arm64, and Linux Flatpak. Source releases are listed for web, REST, desktop, and console clients. A Docker image packages the server, modules, and web client for production deployment. New release series arrive every six months and usually receive one year of support; new major versions receive five years of long-term support. The project offers a shared demo with example data reset daily, plus a community support forum.
