Shopify Nano-SRE: The Open Source Agent for Autonomous Reliability

We are entering the age of Agentic Commerce. Your Shopify store is no longer just a static storefront; it is a complex, living organism of data pipelines, AI models, and API connections. Yet, most merchants are still monitoring it with tools from 2015.

Traditional monitoring tools—which simply ping your site to see if it's "up"—are relics of a simpler time. They cannot see the silent failures that bleed revenue: the dropped webhook, the mismatched inventory, the API rate limit that blocks your flash sale, or the "Add to Cart" button that stops working on mobile.

Shopify Nano-SRE is our answer to entropy. It is an open-source, self-hosted reliability agent designed to live alongside your commerce stack, providing continuous, deep-level observability into the health of your integrations.

The Core Problem: Silent Commerce Failures

Modern Shopify stores are often a "House of Cards" built from dozens of apps, custom theme code, and third-party integrations.

1. The App Bloat Conflict

When multiple apps compete for DOM manipulation—like a "Sticky Add to Cart" bar fighting with a "Bundle Upsell" popup—race conditions occur. The result? A customer clicks "Add to Cart," and nothing happens. No server error (500) is generated. The site appears "up," but the business function is dead.

2. The Checkout Extensibility Blind Spot

The migration to Checkout Extensibility is the massive shift of 2025. While secure, it creates a new risk: broken pixels. If a merchant migrates their UI but fails to correctly wire up their Web Pixels or Customer Events, their ROAS tracking can silently drop to zero. You could be spending thousands on ads with no attribution data to show for it.

Meet Your New SRE: Core Capabilities

Nano-SRE isn't just a script; it's an autonomous agent composed of specialized "Skills" designed to mimic a human Site Reliability Engineer.

The Synthetic Shopper 🛒

The most expensive bugs are the ones that don't throw errors. Nano-SRE uses Playwright to autonomously browse your store like a real customer.

• Autonomous Browsing: It navigates to product pages, adds items to the cart, and verifies that the checkout flow is functional.
• Visual Diagnosis: If a popup blocks a button, it captures a screenshot, uses a Vision LLM (like Claude 3.5 Sonnet) to identify the obstruction, and alerts you with the specific CSS selector causing the issue.

The Webhook Sentinel 🛡️

Shopify's platform is event-driven. Critical updates to inventory, order status, or customer tags rely on webhooks.

The Threat: Shopify will silently remove webhook subscriptions that fail consistently for 48 hours.

The Solution: Nano SRE polls the Admin API to verify subscription health. If a critical webhook (like orders/create) is flagged for removal, the Agent alerts your engineering team instantly.

The Quota Guardian ⚡

API rate limits are the hard ceiling of your store's throughput. Hitting a 429 Too Many Requests error during a flash sale effectively shuts down your operations.

Nano SRE implements a local Token Bucket algorithm that mirrors Shopify’s internal logic. It visualizes your current "cost" consumption in real-time and implements throttling to smooth out traffic spikes before they hit the limit.

Why Open Source?

We believe that reliability is a fundamental right, not a premium feature. By open-sourcing our internal reliability tooling, we aim to raise the standard of engineering across the entire Shopify ecosystem.

• Transparency: Audit the code. Verify the security. No black boxes.
• Community: Built by ShopIntegrations, refined by the global community of Shopify Developers.
• Extensibility: Write your own "Probes" in TypeScript or Python to monitor your specific business logic.

Get Started

Run the agent in your local environment, or deploy it to your cloud of choice. It's built on Python and Playwright, making it lightweight and easy to extend.

# Install via pip
pip install shopify-nano-sre

# Initialize Configuration
nano-sre init --store your-shop.myshopify.com

# Start the Agent
nano-sre watch
