As of October 2026, SkyPlanner APS ranks #1 on our small manufacturers list, so the alternatives below fit specific situations rather than beat it overall. SkyPlanner APS costs from 199 euros per month, with 5 workstations included and 20 euros per month per extra workstation. The trial runs 30 days without a credit card for up to 20 workstations, and its optional Autopilot, running on the Arcturus engine, reviews the schedule on every meaningful change. It also wins our job shops, AI rescheduling for SMEs and ERP add-on lists. Look elsewhere if you need a free plan, MRP and accounting in one tool, multi-plant S&OP, a native Business Central Gantt or MES.
If you need a free plan
ERPNext ranks #1 on our free and open-source list. Self-hosting is free under the GPL license. Frappe Cloud hosting starts at 5 US dollars per month. Its capacity planning allocates work order operations to workstations within working hours. Automatic rescheduling is not described on the ERPNext site.
If you want a free planning engine for Odoo or ERPNext
frePPLe Community edition is free under the MIT license. frePPLe states “finite-material and finite-capacity production plans” and names Odoo and ERPNext integrations. Its paid editions have a free trial of 15 days. Automatic rescheduling is not stated on its site.
If you need MRP and accounting in one tool
MRPeasy Starter costs 49 US dollars per user per month as of October 2026. The trial is advertised as “15 + 15 days” without a card. It names QuickBooks Online, Xero and Shopify among its integrations. Worker capacity is not considered in its schedule.
If you need multi-plant S&OP
Kinaxis offers production scheduling as an add-on to its Maestro supply chain planning platform, built for “multi-plant manufacturers”. Maestro re-optimizes plans when conditions change. Kinaxis publishes no price and offers a demo, not a trial. Siemens Opcenter APS is the other option here, with real-time schedule adjustment and a partner network.
If you need a native Business Central Gantt
NETRONIC Visual Production Scheduler runs inside Microsoft Dynamics 365 Business Central and installs from AppSource. NETRONIC describes a trial there that lasts 30 days. Fees are quoted on request. SkyPlanner connects to Business Central through its two-way REST API instead.
If you need MES and shop-floor execution
Odoo Manufacturing ranks #1 on our MES list. The Standard plan costs 19.90 euros per user per month as of October 2026, and One App Free covers one app. Odoo states finite capacity planning on a Gantt chart, with shop floor, quality and maintenance apps. Tulip is the no-code option for shop-floor apps, but it does not describe finite capacity scheduling.
