Reliable Infrastructure for AI Workflows

The LLM Workflow Router helps engineering teams build AI applications that are predictable, observable, and easier to operate in production. It validates workflow topology before execution, eliminates invalid routing paths, exposes explicit failure states, and integrates with OpenTelemetry for end-to-end visibility—reducing the risk of unexpected behaviour in complex AI systems.

Inspired by the Lumenoid AI Framework, the router focuses on structural safety rather than content moderation. Lumenoid helps applications make responsible AI decisions, while the LLM Workflow Router ensures those decisions flow through explicit, deterministic, and auditable workflows.

Source-Available Core • Commercial License for Production Use

pip install llm-workflow-router

Free to inspect, run, and evaluate — always. Read the full source, try it against your own data, and satisfy yourself it's right. A commercial license is required for any commercial or production use, and includes trust-boundary enforcement, policy validation, tamper-evident auditing, and support.

Read every line before you pay. The full source is open for inspection — nothing hidden, nothing to take on faith.

🛰️ Inspired by the Lumenoid AI Framework

Lumenoid is an open ethical AI architecture that defines reference principles for responsibility, transparency, uncertainty, bounded capability, and human-centred system design. Rather than prescribing model behaviour, it provides architectural foundations that help AI systems remain understandable, accountable, and safe to evolve.

🛡️ Licensing

The core LLM Workflow Router is source-available under the PolyForm Noncommercial License 1.0.0 — free to read, run, and evaluate, with commercial and production use reserved for licensees.

A commercial license grants production use and includes enterprise-grade trust boundaries, policy enforcement, tamper-evident audit trails, and the wfrouter.security.* telemetry convention.

Commercial subscriptions include ongoing security updates, evolving policy packs, compatibility with OpenTelemetry GenAI conventions, and priority support.

💼 Commercial Security Licensing

Early access. The Security Layer is onboarding a small founding cohort. Founding licenses come at introductory pricing in exchange for feedback, and lock in that rate as the product matures. Request current terms and I'll send the details.
