Quickstart – DevLens Components

DevLens is split into three independently deployable services that work together to give you real‑time error monitoring, AI‑powered fixes, and health checks.

Component	What it does	Typical deployment
App	• Web UI for exploring errors & health • Sends alerts to Slack, Teams, PagerDuty, etc. • Manages data retention and archival	1‑node Docker image or a self‑hosted binary
Agent	• Runs on each host (k8s pod, VM, container) • Collects host telemetry (CPU, memory, network) • Acts as a thin wrapper around Sentry SDKs so your app can emit errors without a native Sentry agent	Deploy as a DaemonSet, side‑car, or standalone binary
AI Service	• Forwards error events + surrounding source code & docs to an LLM provider (OpenAI, Anthropic, etc.) • Returns actionable fix suggestions to the UI	Separate Docker image or binary; can be disabled if you don't need AI

The agent and AI service are optional components.

Installation Options

Method	Steps
Docker Compose	docker-compose up -d – pulls all three images, sets environment variables, and connects them.
Single‑binary	Download the platform‑specific binaries for each component from the releases page and run them as system service.

Tip: If you only need the server (e.g., for a quick demo or local deployment), you can skip the agent and AI service; the server will still receive events via the DevLens API.

Once the services are running, navigate to http://localhost:8000 (default) to start exploring your application’s errors, health checks, and AI‑generated fix suggestions.
