Guardian is an Apache 2.0 local safety evaluator. Point it at text and inspect the verdict. Local Ollama checks can run without provider API costs; configured providers, updates, sign-in, and cloud features use their documented networks and terms.
Available as a desktop app (Mac, Windows, Linux) or a publication-gated Python library (python -m pip install creed-guardian==2.1.0). PyPI 0.1.1 is an unsafe preview. The desktop app is a text box with a verdict. The library's asynchronous await guardian.check(action) can return PASS, FAIL, or UNCERTAIN.
First launch downloads the selected local model. Download size depends on the tier. After setup, local Ollama checks can operate offline; configured network features cannot.
What it checks
Creed rules compile to deterministic code. Structural checks (profanity, content categories, format compliance) run without an LLM at near-zero cost. Nuanced judgment calls use the local model.
Every check runs against a set of constitutional principles. Guardian doesn't just pattern-match against a blocklist. It evaluates whether an action is consistent with the governing creed, considering context.

| 1.5B | 2GB | IoT devices, Raspberry Pi |
| 3B | 4GB | Tablets, light laptops |
| 7B | 8GB | Laptops, dev machines |
| 14B | 12GB | Servers, workstations |
| 32B | 24GB | Largest local capacity |
Who uses Guardian
Parents checking content their children encounter from AI. Educators verifying AI-generated teaching materials. Developers adding a safety layer to AI agents. Enterprises needing sovereign, air-gapped AI safety. Robotics teams building safety checks for autonomous systems. Privacy advocates who want AI safety without surveillance.
Guardian vs. Creed Space cloud
Guardian runs locally with default constitutions. It's self-contained.
Creed Space cloud can add custom constitutions (your rules, your values), configured cloud-model evaluation, audit-record and compliance-report design support, fine-grained policy controls, and fleet management. Exact deployment coverage, provider retention, legal interpretation, and independent assurance remain open.
Use Guardian if you want Apache 2.0 licensed local, private, offline-capable safety checks. Hosted services have deployment-specific account, usage, provider, and cost terms.
Open source, Apache 2.0 licensed
Inspect it. Modify it. Ship it commercially. The safety layer should be infrastructure everyone can build on, and that requires transparency in how safety decisions are made.
