Welcome to the Future of Content
Rosmarium COS
The world’s first true Content Orchestration System. Built from the ground up for the agentic web, omnichannel delivery, and enterprise-scale workflows.
The Rosmarium Difference
Most headless CMS platforms were built for the static web, treating AI as a bolt-on plugin. Rosmarium flips the paradigm. We treat AI and graph relationships as foundational infrastructure.
Here is what creates indistinguishable value for enterprise teams running Rosmarium:
Native AI Intelligence
No expensive third-party integrations required. Our dedicated Python ai-worker automatically tags content (NER), generates vector embeddings, and builds instant RAG pipelines the moment you hit publish.
Knowledge Graph Foundation
Stop treating your content as isolated database rows. Rosmarium builds a semantic knowledge graph, enabling complex multi-hop data traversal and surfacing hidden contextual relationships to your users.
Built for Agentic Commerce
Rosmarium doesn’t just output HTML/JSON. It natively supports Model Context Protocol (MCP), allowing AI agents like ChatGPT or Claude to securely query, reason over, and orchestrate your content automatically.
Zero Vendor Lock-in
100% Open Source. Built on enterprise-grade, standard technology: TypeScript, Fastify, Python, and PostgreSQL. Deploy it anywhere, own your data, and completely control your infrastructure.
Core Capabilities
Hybrid Search by Default
We combine blazing-fast BM25 full-text search with pgvector semantic similarity, fusing the results via Reciprocal Rank Fusion (RRF) for unparalleled accuracy.
Visual Workflow Automation
Map out complex organizational publishing rules. Build multi-stage approval chains and schedule content drops seamlessly without writing a line of code.
Global Headless APIs
Consume your content exactly how you want. We provide strongly-typed code-first GraphQL (Pothos) alongside lightning-fast REST endpoints, protected by granular API key authentication.
