[Here ]: Monitorly - API & Website uptime monitoring with real-time alerts
[Here. ]: Software developers, dev teams, SaaS companies (any company with APIs/websites)
[Here. ]: Developers have no way to know if their APIs are down until customers complain; fixing outages takes 2-3x longer without real-time alerts
[Here ]: 3,500 in Year 1 (development teams)
[MVP / Revenue / Scale / Enterprise]: MVP ā Revenue within 4 months
Example output
## š **SECTION 1 ā BUSINESS VALIDATION**
### Market Opportunity Assessment
**Market Demand**: ā
VALIDATED
- 30M+ developers worldwide
- 2.8M SaaS companies (each needs uptime monitoring)
- API downtime costs $1,000-10,000/hour per company
- 45% of developers manually check API health (no automation)
- $3.1B infrastructure monitoring market (2025)
- Monitoring market growing 18% YoY
**Customer Pain Points**:
- ā No automatic alerts when APIs go down (find out from angry customers)
- ā Manual health checks via curl/Postman waste developer time
- ā Incidents take 3-4x longer to fix without real-time monitoring
- ā No visibility into API performance (latency, error rates)
- ā Existing tools (Datadog, New Relic) overkill + $500+/mo
- ā Can't see which endpoint failed (dependency tracking)
- ā No status page for customers (opaque about outages)
**Competitive Analysis**:
| Competitor | Pricing | Weakness |
|---|---|---|
| UptimeRobot | $5-300/mo | Basic, poor API monitoring |
| Statuspage | $29-599/mo | Status page only, no monitoring |
| Pingdom | $10-109/mo | Limited for modern APIs |
| Datadog | $15-50+/host/mo | Enterprise, overkill for startups |
| New Relic | $99-1000+/mo | Expensive, complex setup |
| **Monitorly** | **$19-149/mo** | **Simple API-first, fast, affordable** |
**Differentiation**:
- API-first (not just HTTP pings)
- Response validation (check JSON response, not just status code)
- Global monitoring locations (monitor from 20+ cities simultaneously)
- Slack/PagerDuty/Teams integration (alerts where devs live)
- Public status page (auto-generated from monitoring)
- Performance analytics (response time trends, error rate tracking)
- Custom webhook retries (validate entire workflow)
**Revenue Opportunity**:
- TAM: $105M (7M teams Ć $15 ARPU)
- Year 1: 3.5K users Ć $19-40 avg Ć 12 = $950K potential
- Path to Profitability: 2 months after launch
**Opportunity Score**: š¢ **8.7/10** ā Large TAM, clear pain, high retention, usage-based growth

āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāā
BACKGROUND WORKERS:
āā Monitor Scheduler (triggers checks every N minutes)
āā Alert Processor (processes alert rules)
āā Incident Detector (identifies outages)
āā Webhook Retry Handler (reliable delivery)
āā Report Generator (daily/weekly reports)
āā Cleanup Worker (archive old data)
āā Status Page Renderer (generate static pages)
```
**Key Architectural Differences**:
- ā
Distributed monitoring network (multiple locations)
- ā
Real-time alerting (WebSocket for dashboard updates)
- ā
Time-series database (store monitoring metrics efficiently)
- ā
High availability (if one monitor location fails, others pick up)
- ā
Webhook delivery (guaranteed retry logic)
- ā
Static status page generation (fast, cacheable)
- ā
Horizontal scaling (add more monitor agents)

return { status, avgResponseTime, checks };
}
}
```
**CheckExecutor** (Performs HTTP checks):
```typescript
class CheckExecutor {
async executeCheck(monitorId: string, location: string) {
const monitor = await Monitor.findByPk(monitorId);
const startTime = Date.now();
try {
// Make HTTP request
const response = await axios({

// "response.json.status" -> obj.json.status
return path.split('.').reduce((curr, prop) => curr?.[prop], obj);
}
}
```
**IncidentService** (Tracks outages):
```typescript
class IncidentService {
async detectIncident(monitorId: string, location: string, success: boolean) {
// Get previous check result
const previousCheck = await Check.findOne({
where: { monitor_id: monitorId, location },
order: [['created_at', 'DESC']],

const incident = await Incident.create({
monitor_id: monitorId,
location,
started_at: new Date(),
ended_at: null,
status: 'investigating'
});
// Trigger alerts
await AlertService.sendAlert(monitorId, {
type: 'down',
incident_id: incident.id
});
}
// Transition from DOWN ā UP = incident resolved
if (!previousSuccess && success) {
const incident = await Incident.findOne({
where: {
monitor_id: monitorId,
location,
ended_at: null
},
order: [['started_at', 'DESC']]
});
if (incident) {
incident.ended_at = new Date();
incident.status = 'resolved';
await incident.save();
// Trigger recovery alert
await AlertService.sendAlert(monitorId, {
type: 'recovered',
incident_id: incident.id,
duration: incident.ended_at - incident.started_at
});
}
}
}
}
```
**AlertService** (Send notifications):
```typescript
class AlertService {
async sendAlert(monitorId: string, { type, incident_id, duration }) {
const monitor = await Monitor.findByPk(monitorId);
const user = await User.findByPk(monitor.user_id);
const alertConfigs = await AlertConfig.findAll({

await WebhookQueue.add({
webhookUrl: config.webhook_url,
payload: {
monitor: monitor.name,
type,
incidentId: incident_id,
timestamp: new Date()
}
});
}
}
}
private async sendEmailAlert(email: string, monitorName: string, type: string, duration?: number) {
const subject = type === 'down'
? `š“ ${monitorName} is DOWN`
: `š¢ ${monitorName} is back UP`;
const message = type === 'down'
? `Your monitor "${monitorName}" is experiencing issues.`
: `Your monitor "${monitorName}" has recovered (was down for ${this.formatDuration(duration)}).`;
await SendGrid.send({
to: email,
subject,
text: message
});
}
}
```
**StatusPageService** (Public status page):
```typescript
class StatusPageService {
async generateStatusPage(statusPageId: string) {
const statusPage = await StatusPage.findByPk(statusPageId);
const monitors = await Monitor.findAll({
where: { status_page_id: statusPageId }

**Key Design Decisions**:
- ā
TimescaleDB for checks (time-series optimized)
- ā
Hypertables auto-compress old data
- ā
Continuous aggregates (pre-computed analytics)
- ā
Webhook delivery logs (reliable alert delivery)
- ā
Usage metrics (for billing calculations)
- ā
Status pages table (support white-label)
- ā
Monitor locations as JSONB (flexible, can add new locations)

## š **SECTION 8 ā SECURITY & AUTHENTICATION**
### API Key Authentication
```typescript
// For programmatic access (monitoring agents)
class APIKeyService {
async generateAPIKey(userId: string): Promise<string> {
const key = crypto.randomBytes(32).toString('hex');
const hash = crypto.createHash('sha256').update(key).digest('hex');
await APIKey.create({
user_id: userId,
key_hash: hash,
name: 'Default key',
created_at: new Date()
});
return key; // Return once, don't store plaintext
}
async validateAPIKey(key: string): Promise<string | null> {
const hash = crypto.createHash('sha256').update(key).digest('hex');
const apiKey = await APIKey.findOne({ where: { key_hash: hash } });
return apiKey?.user_id || null;
}
}
// In middleware
app.use('/api', async (req, res, next) => {
const apiKey = req.headers['x-api-key'];
if (apiKey) {
const userId = await APIKeyService.validateAPIKey(apiKey);
if (userId) {
req.user = { id: userId };
return next();
}
}
res.status(401).json({ error: 'Invalid API key' });
});
```
### Webhook Signature Verification
```typescript
// Verify webhooks from customer servers
class WebhookSignatureService {
generateSignature(payload: string, secret: string): string {
return crypto
.createHmac('sha256', secret)
.update(payload)
.digest('hex');
}
verifySignature(payload: string, signature: string, secret: string): boolean {
const expected = this.generateSignature(payload, secret);
return crypto.timingSafeEqual(
Buffer.from(signature),
Buffer.from(expected)
);
}
}
// In webhook handler
app.post('/webhooks/customer-events', (req, res) => {
const signature = req.headers['x-monitorly-signature'];
const payload = req.rawBody;
const secret = process.env.WEBHOOK_SECRET;
if (!WebhookSignatureService.verifySignature(payload, signature, secret)) {
return res.status(401).json({ error: 'Invalid signature' });
}
// Process webhook...
});
```
### Rate Limiting (Strict for API)
```typescript
// Use Redis for distributed rate limiting
const rateLimiter = new RateLimiter({
redis,
keyPrefix: 'rl:',
points: 1000, // 1000 points per windowMs
duration: 60 // per 60 seconds
});
app.use('/api', async (req, res, next) => {
try {
await rateLimiter.consume(req.user.id);
next();
} catch (err) {
res.status(429).json({
error: 'Rate limit exceeded',
retryAfter: Math.ceil(err.msBeforeNext / 1000)
});
}
});
```
### Data Privacy
```typescript
// Encryption for sensitive data
class EncryptionService {
static encrypt(value: string): string {
const iv = crypto.randomBytes(16);
const cipher = crypto.createCipheriv(
'aes-256-cbc',
Buffer.from(process.env.ENCRYPTION_KEY, 'hex'),
iv
);
let encrypted = cipher.update(value);
encrypted = Buffer.concat([encrypted, cipher.final()]);
return iv.toString('hex') + ':' + encrypted.toString('hex');
}
}
// Encrypt webhook URLs, API keys, etc
class AlertConfig {
setWebhookUrl(url: string) {
this.webhook_url = EncryptionService.encrypt(url);
}
}
```

2. **Time-series expertise**: Use TimescaleDB, not generic PostgreSQL
3. **Real-time**: Implement WebSocket for instant dashboard updates
4. **Alerting reliability**: Webhook retries with exponential backoff
5. **Horizontal scaling**: Design check executor to scale horizontally
6. **Observability**: Monitor the monitor (Prometheus + Grafana)
7. **Testing**: Mock API failures extensively
8. **Team structure**: 2 backend engineers (one specializing in distributed systems)
9. **Database**: Start with TimescaleDB, not regular PostgreSQL
10. **Pricing**: Build metering/usage tracking into API from day 1
---
