The reference runtime for the OGR protocol

Quick start

Self-host it

The runtime ships as two container images — openguardrails/runtime-web (console + API) and openguardrails/runtime-worker (ingest pipeline) — plus the datastores: PostgreSQL or MySQL for config and findings, ClickHouse or Apache Doris for event analytics, Redis for queues. Everything is configured with env vars; migrations run automatically on web startup.

services:
  web:                                  # console + Runtime API
    image: openguardrails/runtime-web
    ports: ["3000:3000"]
    env_file: .env
  worker:                               # ingest -> analytics, findings
    image: openguardrails/runtime-worker
    env_file: .env
  # plus datastores, wired via .env:
  #   postgres (or your MySQL)  – config, policies, findings
  #   clickhouse (or your Doris) – event analytics
  #   redis                      – queues and caches

# .env — headless bootstrap (idempotent, reconciled on every boot)

OGR_INIT_USER_PASSWORD=change-me
OGR_INIT_WORKSPACE_NAME=default
OGR_INIT_API_KEY=ogr_your_own_key      # ogr_-prefixed, >= 20 chars

# optional: model-backed detectors. Without it, model checks
# fall back to a regex mock — fine for wiring, not for production.

On Kubernetes, use the openguardrails-runtime Helm chart — it bundles single-replica datastores for a trial, or points at your managed PostgreSQL/ClickHouse/Redis for production:

helm install ogr openguardrails-runtime \
  --set secrets.nextauthSecret=$(openssl rand -hex 32) \
  --set secrets.salt=$(openssl rand -hex 16)

kubectl port-forward svc/ogr-openguardrails-runtime-web 3000:3000

First run: from key to first verdict

1. Open the console at http://localhost:3000 and sign in (or bootstrap headlessly with the OGR_INIT_* vars above).
2. Under API keys, pick a workspace and create a key (ogr_...). Under Policies, create a policy and assign it to that workspace.
3. Point a plugin's OGR_RUNTIME_URL at the runtime, and watch events arrive in the live monitor.

# 1. The runtime is up when /v1/health says so (no auth needed)
curl -s http://localhost:3000/v1/health
# {"status":"ok","version":"..."}

# 2. Point any OGR plugin at it
export OGR_RUNTIME_URL=http://localhost:3000
export OGR_API_KEY=ogr_your_own_key

# 3. Send an event; watch it land in the live monitor
curl -s $OGR_RUNTIME_URL/v1/evaluate \
  -H "Authorization: Bearer $OGR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "ogr_version": "0.4",
    "event_id": "evt_1", "guard_id": "g_1",
    "timestamp": "2026-08-11T09:30:00Z",
    "observation_point": "invocation", "kind": "exec",

  }'

Any plugin from the showcase speaks this contract out of the box — Claude Code, Codex, opencode, OpenClaw, Hermes, LangGraph, Higress, mitmproxy, the eBPF sensor.

The contract

The API it serves

This runtime is the reference implementation, not the only one. The Runtime API — /v1/evaluate, /v1/ingest, enrollment, heartbeat, config, approvals — is an open, Apache-2.0 specification with published JSON Schemas. Anyone can implement a conforming runtime; every OGR SDK and plugin will speak to it unchanged.
