What you’ll learn to build
- Understand a baseline and a single safe HTTP check
- Detect a meaningful change without confusing network failure with content change
- Build a respectful, testable monitoring workflow
Who it’s for
Beginner-to-intermediate Python learners interested in web requests, monitoring and reliable scripts. Start after running and modifying a small Python script.
Two focused lessons
- 01
Run and understand the working tool
- 02
Test, extend and document the workflow

- HTTP errors can be informative
- Read the generated report
- Be a considerate network neighbor
- Dynamic page false positives
- Milestone: baseline, change, exception
- Design a pure comparison function
- Never erase a good baseline on errors
- Timeouts are design decisions
- Body size caps
- Duplicate and empty URL lists
- Local state file ownership
- Redirects affect what you measure
- Alerts are a separate concern

- Error messages as operating evidence
- Offline test matrix
- Monitoring ethics and security
- Roadmap to observability
Project boundaries
A command-line monitor, not a hosted uptime service. Dynamic HTML may produce harmless changes. Monitor only authorized URLs; no email or SMS alerts.
