I Replaced 3 SaaS Tools With One Python Script: Here's What I Learned

The average small team pays $147/month for tools that one well-written script can replace.

I spent six months auditing our SaaS stack and found something uncomfortable: we were paying for three separate tools that all did variations of the same thing — monitoring, alerting, and reporting. Each cost $49/month. Each had its own login, its own dashboard, its own way of doing things.

Then I wrote 200 lines of Python.

The Problem: Tool Sprawl Is Eating Your Budget

Reality Check: The average small business uses 73 SaaS tools. Most overlap in functionality. The cost isn't just the subscription — it's the context switching, the integration maintenance, and the cognitive load of keeping track of it all.

Here's what our stack looked like:

Tool	Purpose	Monthly Cost
Uptime Robot	Monitoring	$49
PagerDuty Lite	Alerting	$49
StatusPage	Reporting	$49
Total		$147/month

The Solution: One Script, Three Functions

The script does three things:

1. Health Checks (Replaces Uptime Robot)

import requests
import time
from datetime import datetime

def check_endpoint(url, expected_status=200):
    try:
        start = time.time()
        response = requests.get(url, timeout=10)
        latency = (time.time() - start) * 1000
        return {
            'url': url,
            'status': response.status_code,
            'healthy': response.status_code == expected_status,
            'latency_ms': round(latency, 2),
            'timestamp': datetime.now().isoformat()
        }
    except Exception as e:
        return {'url': url, 'status': 0, 'healthy': False, 'error': str(e)}

2. Alerting (Replaces PagerDuty)

def send_alert(endpoint, issue):
    # Send to Slack, email, or SMS
    message = f"🚨 ALERT: {endpoint} is DOWN - {issue}"
    # webhook_url from environment variable
    requests.post(webhook_url, json={'text': message})

    # Escalate if critical
    if issue.get('severity') == 'critical':
        send_sms(on_call_number, message)

3. Status Reporting (Replaces StatusPage)

def generate_status_report(checks):
    healthy = sum(1 for c in checks if c['healthy'])
    total = len(checks)
    uptime_pct = (healthy / total) * 100 if total > 0 else 0

    report = f"""
    # System Status Report
    Uptime: {uptime_pct:.1f}%
    Healthy: {healthy}/{total}

    ## Endpoint Details
    """
    for check in checks:
        status = '✅' if check['healthy'] else '❌'
        report += f"{status} {check['url']} - {check.get('latency_ms', '?')}ms\n"

    return report

The Results

After 30 days:

• $147/month saved → $1,764/year
• Zero context switching between tools
• Customizable alerts — no more "upgrade to Pro for custom rules"
• Full data ownership — all logs stay on our server

What I Learned

1. Most SaaS Tools Are CRUD Apps With Nice UIs

The core functionality of monitoring, alerting, and reporting is simple. The value proposition of SaaS tools isn't the technology — it's the polish, the integrations, and the support. If you don't need those, you don't need the tool.

2. The 80/20 Rule Applies Hard Here

80% of the value came from 20% of the features. We used uptime checking, basic alerting, and a status page. We didn't need AI-powered anomaly detection, custom dashboards, or team collaboration features.

3. Ownership Has Hidden Value

When the script breaks, I fix it in 10 minutes. When a SaaS tool breaks, I open a support ticket and wait 48 hours. That difference compounds over a year.

When You SHOULD Keep SaaS Tools

This isn't anti-SaaS. Keep paying when:

• You need enterprise compliance (SOC2, HIPAA) — don't build your own audit trail
• Your team is non-technical — the UI is worth the cost
• You need massive scale — 1000+ endpoints need infrastructure, not a script
• The tool is core to your business — focus on your product, not your monitoring

The Bigger Lesson

Audit your SaaS stack every quarter. Ask: "Could a script do 80% of this?" If yes, you're paying for convenience. Sometimes that's worth it. Often it's not.

The script took me 4 hours to write. It saved $1,764/year. That's $441/hour of value. Your time is worth more than SaaS subscriptions.
