+# prism-web-console
+
+Web-based admin console for Prism data access gateway.
+
+**Status:** Initial implementation - separated from prism-admin control plane
+
+## Overview
+
+`prism-web-console` provides a web-based UI for managing Prism:
+- Namespace management (create, list, delete)
+- Session monitoring
+- Backend health dashboard
+- Operational tasks
+
+This service is separate from `prism-admin` (the control plane gRPC server) to provide:
+- Clear separation of concerns (control plane vs UI)
+- Independent scaling and deployment
+- Technology flexibility (web framework choice independent of control plane)
+
+## Architecture
+
+Based on RFC-036: Minimalist Web Framework for Prism Admin UI
+
+```
+Browser → prism-web-console (:8000) → prism-admin (:8981)
+          (Gin + templ + htmx)         (gRPC Control Plane)
+```
+
+**Technology Stack:**
+- **Gin**: HTTP routing and middleware
+- **templ**: Type-safe HTML templates (to be added)
+- **htmx**: HTML over the wire interactions
+- **Tailwind CSS**: Utility-first styling
+
+## Installation
+
+### Build from Source
+
+```bash
+cd cmd/prism-web-console
+go build -o prism-web-console .
+```
+
+### Install Globally
+
+```bash
+cd cmd/prism-web-console
+go install .
+```
+
+## Usage
+
+### Start the Server
+
+```bash
+# Default: http://0.0.0.0:8000
+prism-web-console
+
+# Custom port
+prism-web-console --port 8080
+
+# With admin endpoint
+prism-web-console --admin-endpoint localhost:8981
+```
+
+### Configuration
+
+Configuration precedence (highest to lowest):
+1. Command-line flags
+2. Environment variables (prefix: `PRISM_`)
+3. Config file (`~/.prism.yaml` or `./.prism.yaml`)
+4. Defaults
+
+**Environment Variables:**
+
+```bash
+export PRISM_SERVER_PORT=8000
+export PRISM_SERVER_LISTEN=0.0.0.0
+export PRISM_ADMIN_ENDPOINT=localhost:8981
+export PRISM_LOGGING_LEVEL=info
+```
+
+**Config File** (`~/.prism.yaml`):
+
+```yaml
+server:
+  listen: 0.0.0.0
+  port: 8000
+  mode: release  # debug or release
+
+admin:
+  endpoint: localhost:8981
+
+logging:
+  level: info
+```
+

+### Running Locally
+
+```bash
+# Start prism-admin control plane
+cd cmd/prism-admin
+go run . serve --port 8981
+
+# Start web console (in another terminal)
+cd cmd/prism-web-console
+go run . --port 8000
+
+# Open browser
+open http://localhost:8000
+```
+
+### Testing
+
+```bash
+# Run tests
+go test ./...
+
+# Run with coverage
+go test -coverprofile=coverage.out ./...
+go tool cover -html=coverage.out
+```
+
+## Docker Deployment
+
+### Build Image
+
+```bash
+# From repository root
+make docker-build-service SERVICE=prism-web-console VARIANT=scratch
+```
+
+### Run Container
+
+```bash
+docker run -p 8000:8000 \
+  -e PRISM_ADMIN_ENDPOINT=prism-admin:8981 \
+  prism-web-console:scratch
+```
+
+### Docker Compose
+
+```yaml
+services:
+  prism-admin:
+    image: prism/admin:latest
+    ports:
+      - "8981:8981"
+
+  prism-web-console:
+    image: prism/web-console:latest
+    ports:
+      - "8000:8000"
+    environment:
+      PRISM_ADMIN_ENDPOINT: prism-admin:8981
+      PRISM_LOGGING_LEVEL: info
+    depends_on:
+      - prism-admin
+```
+
+## API Endpoints
+
+### Health Check
+
+```bash
+GET /health
+```
+
+**Response:**
+```json
+{
+  "status": "healthy",
+  "service": "prism-web-console"
+}
+```
+
+### Web UI Routes
+
+- `GET /` - Admin dashboard
+- `GET /namespaces` - Namespace list
+- `POST /namespaces` - Create namespace
+- `DELETE /namespaces/:name` - Delete namespace
+- `GET /sessions` - Session monitoring
+- `GET /health-dashboard` - Backend health
+
+## Authentication
+
+OIDC authentication integration (to be implemented):
+- Session-based authentication
+- JWT validation
+- Integration with Dex IdP (RFC-010)
+
+## References
+
+- RFC-036: Minimalist Web Framework for Prism Admin UI
+- ADR-028: Admin UI with FastAPI and gRPC-Web
+- [Gin Web Framework](https://gin-gonic.com/)
+- [templ](https://templ.guide/)
+- [htmx](https://htmx.org/)

+## Revision History
+
+- 2025-10-22: Initial separation from prism-admin
