Workflow coverage and comparison notes
Open-source knowledge base Q&A platform with visual workflow orchestration, vector search, and custom AI chatbot embedding replacing CustomGPT ($99+/mo) subscriptions.
Before you switch
Modified licence restricts similar multi-tenant SaaS and removing console branding. Requires your own server and model setup; some authentication features are paid. Keep current: an iframe resize/state-loss issue in 4.16.0 was fixed upstream on September 9, 2026.
