As of October 2026, the best alternative to Katana for manufacturers that need a real production schedule is SkyPlanner APS, which ranks #1 of 10 on our small manufacturers list, where Katana ranks #7. SkyPlanner APS costs from 199 euros per month, with 5 workstations included and 20 euros per month per extra workstation. Its trial runs 30 days without a credit card for up to 20 workstations, and its Autopilot reschedules the plan continuously with the Arcturus engine. Katana makes no explicit finite capacity scheduling claim, models capacity as weekly throughput, and does not publish a price for its paid Advantage plan. The five other alternatives below fit specific situations: MRP and accounting in one tool, the lowest paid price, a free open-source ERP, a free job shop plan and multichannel inventory.
If you want finite capacity scheduling and automatic rescheduling with a public price
SkyPlanner APS publishes its price: from 199 euros per month as of October 2026, with 5 workstations included and 20 euros per month per extra workstation. Its trial runs 30 days without a credit card for up to 20 workstations. SkyPlanner schedules to finite capacity, and Autopilot reschedules continuously with the Arcturus engine, on an interval or when an event changes the plan. It connects to any ERP or MES through a two-way REST API with webhooks and CSV import; customer projects have connected SAP, Microsoft Dynamics 365, Odoo, Epicor, Sage and Siemens. Self-onboarding in the free trial uses demo data, tutorial videos, a Getting Started guide and the built-in AI agent; the first schedule runs on demo data in minutes and simple production fits in a day. No ERP is needed to start.
If you need MRP and accounting connections in one tool
MRPeasy ranks #2 on our small manufacturers list. Its Starter plan costs 49 US dollars per user per month as of October 2026, and the trial is advertised as “15 + 15 days” with no credit card.
