Startups move fast. Monitoring often feels like something to "set up later" — but downtime at a critical moment (a Product Hunt launch, a TechCrunch mention, a demo for investors) can be catastrophic. This guide gives you the pragmatic startup approach to uptime monitoring: what you actually need, when you need it, and how to set it up in an afternoon.
Why Startups Need Monitoring Earlier Than They Think
Pre-launch: "We don't have users yet, so downtime doesn't matter."
This is wrong. During launch prep, every founder and potential early adopter who can't reach your site is a missed opportunity. You need to know when your app is down even before you have real users.
Early stage (1-100 users): At this stage, individual users matter enormously. One churned user who left because of downtime they never told you about is a missed reference.
Growth stage (100-10,000 users): Downtime now has real revenue impact. Every minute offline is money and churn.
What a Startup Actually Needs to Monitor
Start simple. Don't monitor 50 things when you have 3 users.
MVP Monitoring (Day 1)
- Your main URL: Is the homepage/landing page responding?
- Your API: Is the core API responding?
- SSL cert: Will it expire in the next 30 days?
That's it for the first month. Three monitors, takes 10 minutes to set up with Vigilmon.
Launch Monitoring (Pre-launch week)
Add:
- Signup/onboarding endpoint: The most critical user flow
- Dashboard or core feature: The thing users pay for
- Payment endpoint (if applicable): Stripe webhooks, checkout
Scaling Monitoring (10+ users)
Add:
- Database health check: Is your app able to query the DB?
- Background jobs: Are your scheduled tasks and queues running?
- CDN: Is your static asset delivery working?
Setting Up Monitoring with Vigilmon
vigilmon.online has a free tier that covers everything you need as an early-stage startup.
Step 1: Create your account
Takes 60 seconds. No credit card required.
Step 2: Add your main URL
- Click Add Monitor → HTTP
- Enter
https://your-startup.com - Set interval: 60 seconds
- Enable multi-region (critical — prevents false alerts from single-region hiccups)
Step 3: Add your API
Add https://api.your-startup.com/health (create a /health endpoint that returns {"status":"ok"} — 5 minutes of work).
Step 4: Add SSL monitoring
Turn on SSL certificate monitoring for your domain. Set alert threshold to 30 days before expiry.
Step 5: Configure alerts
Set up email alerts at minimum. Add Slack if you use it. If you're close to launch, add PagerDuty or SMS.
Pre-Launch Day Checklist
The 24 hours before a big launch:
- [ ] All monitors green for 24 hours before launch
- [ ] Alerts configured and tested (send a test alert)
- [ ] Team knows the on-call protocol (who gets paged if site goes down at 3am?)
- [ ] Status page created and linked from your site
- [ ] You've tested the signup flow manually in the last 2 hours
During a Launch Event
When you're live on Product Hunt, Show HN, or getting press coverage:
- Keep the Vigilmon dashboard open in a browser tab
- Lower alert thresholds temporarily (if response times spike, alert immediately)
- Have your hosting/DB console ready if you need to scale up quickly
- Have someone dedicated to monitoring while others do outreach
The Startup Incident Response Playbook
When Vigilmon alerts you:
- Acknowledge the alert (marks it as seen in team channels)
- Check the monitoring dashboard — which endpoint? How many regions?
- Check your hosting dashboard — is the server crashed? Out of memory?
- Check deploy history — did a deployment just go out?
- Fix or rollback
- Communicate via status page — even 10 users deserve to know
Common Startup Downtime Causes
| Cause | Detection |
|---|---|
| Ran out of free hosting hours | HTTP monitor shows 503 |
| Database connection limit hit | Health check returns 503 |
| SSL cert expired | SSL monitor alerts 30 days before |
| Bad deployment | Monitor shows 500 after deploy |
| Memory leak | Response times increase over hours |
| DDOS or traffic spike | Alert fires; check hosting dashboard |
Status Pages for Startups
Create a public status page at status.your-startup.com. Why?
- Users check status pages when your site is down
- It reduces "is your site broken?" support tickets
- It communicates professionalism to investors and prospects
- Vigilmon creates one for you for free
Monitoring Costs at Each Stage
Pre-revenue startup: Vigilmon free tier. $0/month.
Seed stage: Vigilmon paid plan for more monitors. $10-30/month.
Series A: Add APM (Datadog or similar) for internal observability. $50-200/month.
Uptime monitoring should never be a significant line item for a startup. The cost of a single hour of undetected downtime dwarfs the monitoring tool cost.
The One Thing
If you take nothing else from this guide: add one monitor for your main URL today. Not tomorrow. Not after launch. Right now.
It takes 5 minutes. The next time your site goes down, you'll know in 60 seconds — not when a user tweets at you.
