# How to Vibe Code Your Own Pingdom (and Stop Paying for It)

> Website Monitoring Service - Availability and Performance

- Site: https://pingdom.com
- Category: DevOps & Monitoring
- Verdict: **Solid side project** (65/100 vibecodeable)
- Estimated effort: 2-3 weeks part-time

## Verdict

Build a personal uptime and status page dashboard, but keep paying for enterprise synthetic networks if you need 100 global edge points.

You can build a fully functional personal monitoring tool with cron-based checks, status pages, and an email alerting engine using modern AI coding agents. However, mimicking a commercial distributed probe network across 100+ physical countries and heavy RUM time-series ingestion pipelines requires significant infrastructure engineering beyond a quick side project.

### What you can't replicate

- Physical global probe presence across 100+ isolated datacenter regions
- SolarWinds enterprise customer base and brand ecosystem

## What it does

Pingdom is an availability and performance monitoring SaaS platform for websites, web applications, and servers, offering synthetic uptime checks, page speed waterfalls, transaction monitoring, real user monitoring (RUM), and public status pages.

### Core features

- Global uptime synthetic ping checks (HTTP, TCP, DNS)
- Page speed performance testing with waterfall charts
- Multi-step transaction monitoring via headless browsers
- Real User Monitoring (RUM) via tracking JavaScript snippet
- Multi-channel alerting (Email via Resend, Webhooks)
- Public status pages with uptime history
- Root cause analysis (traceroutes and response headers)

## The business

### Pricing

- Synthetic Monitoring: Custom / Tiered — Scaled tiers based on uptime checks, advanced checks, and SMS credits.
- Real User Monitoring (RUM): Tiered by volume — Tracks actual visitor pageviews and client-side performance.

### Funding

$0 raised.

Founded 2005.
Team size: Subsidiary of SolarWinds.

## The hard parts

- Orchestrating a reliable distributed global polling worker fleet to prevent false positives from regional network blips
- Running headless browser pools (Playwright) at scale securely for complex multi-step transaction checks
- High-throughput time-series ingestion and aggregation pipelines for massive RUM event streams
- Ensuring zero message loss and rate limiting across alerting escalation paths

## How to vibe code Pingdom

### Prerequisites

- Node.js (free): Required runtime for the Next.js application framework and agent tooling.
- GitHub (free): Source code control and deployment pipeline integration.

### Recommended AI tools

- Claude Code: Best-in-class multi-file agentic coding tool for scaffolding the monitoring backend and dashboard UI.

### Stack

- Frontend: Next.js
- Backend: Next.js API Routes / Cloudflare Workers
- Database: Turso
- Auth: better-auth
- Payments: none
- Other: Resend, Tailwind CSS, shadcn/ui

### Hosting

- Cloudflare (Hosting frontend and edge cron worker pollers): $0-5/mo

### Build guide

1. **Project Scaffolding and Database Schema** — Initialize the Next.js project with Tailwind CSS, shadcn/ui components, and configure Turso SQLite connection for checks, incidents, and RUM telemetry.

```
Create a new Next.js project with TypeScript, Tailwind CSS, and shadcn/ui. Set up a Turso database connection using Drizzle ORM. Define schemas for users, monitors (url, frequency, type, expected_status), check_results (monitor_id, timestamp, response_time_ms, status_code, is_up, region), incidents (monitor_id, started_at, resolved_at), and rum_events (monitor_id, pageviews, load_time_ms, browser, device, timestamp). Ensure all table relationships and indexes are properly structured for time-series range queries.
```

2. **Authentication & Dashboard Shell** — Implement authentication using better-auth and build the core SaaS dashboard layout with overview statistics, monitor lists, and navigation.

```
Integrate better-auth into the Next.js application supporting email/password and secure session management. Build a responsive dashboard shell featuring a sidebar navigation (Dashboard, Monitors, RUM, Status Pages, Settings), a top bar with user profile actions, and a main content area displaying high-level system uptime metrics, active incident counts, and recent check response time summaries.
```

3. **Synthetic Polling Engine & Cron Worker** — Implement the synthetic monitoring cron engine that periodically pings target URLs, measures latency, records status codes, and handles false-positive verification checks.

```
Build a robust synthetic monitoring engine using Cloudflare Workers Cron Triggers or Next.js API cron routes. The engine must iterate through active monitors, perform an HTTP GET request with a strict timeout (e.g., 10 seconds), record response time and status code, and execute a secondary validation check upon failure to prevent false positives. Store all telemetry in the check_results table and trigger incident records when state changes from up to down.
```

4. **Alerting & Notification Dispatcher** — Implement notification channels via Resend email API and webhooks to dispatch instant alerts when monitors go down or recover.

```
Create a notification dispatch module that integrates with the Resend API to send immediate downtime and uptime recovery email alerts to configured recipients. Add support for outbound webhook dispatches with payload signing (HMAC). Include configurable alert delay settings and cooldown intervals to avoid notification fatigue during flapping outages.
```

5. **Real User Monitoring (RUM) & Client Snippet** — Build the RUM ingestion endpoint and provide a lightweight JavaScript tracking snippet for users to embed on their websites.

```
Develop a lightweight, high-performance JavaScript tracking snippet that collects client-side performance metrics (Navigation Timing API load times, browser user-agent, device type, geographic hints) and beacons them back via an unauthenticated, CORS-enabled Next.js API ingestion route. In the backend handler, ingest these payloads into the rum_events table with minimal latency and aggregate them for user dashboard visualization.
```

6. **Public Status Pages & Root Cause Analysis** — Build customizable public status pages showing uptime history graphs and incident timelines, along with basic root cause response headers and traceroute diagnostics.

```
Build a public status page module allowing users to publish selected monitors to a customizable public URL (e.g., /status/my-service). Render 90-day uptime history bars, active incident banners, and maintenance windows. Also build a root cause analysis view for individual check failures displaying response headers, SSL certificate status, and simulated traceroute logs.
```

### Cost vs paying

**Starting costs (one-time):**

- Domain name (optional): $12
- Total: ~$12 one-time

**Ongoing costs (monthly):**

- Cloudflare Workers & Turso DB: $0/mo (Hobby Tiers)
- Resend Transactional Email: $0/mo (Free tier up to 3k emails)
- Total: ~$0/mo

- Paying for the SaaS instead: $34/mo+
- Build time: 25-35 hours
- AI tool credits: $20
- Break-even: 0 months (Free self-hosted stack)
