Tryton
Tryton is a modular, Python/PostgreSQL-based open-source ERP released under GPL-3 by the Tryton Foundation, with a CRM module for lead and opportunity tracking alongside unusually deep financial accounting and supply-chain modules. It targets medium-to-large organisations that prioritise long-term stability and developer extensibility over SaaS convenience.

Our verdict
Last verified Jun 12, 2026
Exceptionally deep accounting and ERP breadth; CRM module is functional but thin compared to dedicated CRM tools; minimal GitHub star count (193) reflects niche but loyal adopter base, and no third-party aggregate ratings found.
