Flectra
Flectra is an open-source ERP and CRM suite forked from Odoo, built on Python and PostgreSQL, and deployable on your own infrastructure. It includes a CRM module for sales pipeline and contact management, alongside accounting, inventory, HR and e-commerce modules, with a one-time on-premise licence available for teams that want perpetual self-hosted use.

Our verdict
Last verified Jun 12, 2026
Viable Odoo fork with perpetual on-premise licence option; low GitHub adoption (129 stars) and smaller community than Odoo limit confidence, and an Odoo lawsuit over copyright raised concerns about long-term legal standing.
