Most small-business ERP software means a monthly bill per user and your business data living on someone else's servers. Celerp flips that: it's a desktop app you download and run, with your data staying on your own machine by default. Celerp is a free, self-hosted ERP that bundles inventory management (FIFO/FEFO/LIFO costing), invoicing, purchase orders, CRM and double-entry accounting into one desktop application, with PostgreSQL bundled in so there's nothing separate to install. It runs on Windows, macOS and Linux, supports unlimited users on every plan (no per-seat pricing), and exposes a REST API compatible with Claude and GPT-4 for automation. The core is dual-licensed: BSL 1.1 for the engine and MIT for default modules — open enough to inspect and extend, but not a fully permissive open-source license. Optional paid tiers (Connect at $29/month, Connect+AI at $49/month) add cloud sync, backups and integrations with Shopify, WooCommerce, Xero and QuickBooks.
