We treat cloud cost as a code bug and catch it before deployment using static analysis.
A local tool that detects cost-heavy code patterns in Python, JavaScript, and Java, estimates cloud cost in ₹ (Indian Rupees), and suggests fixes before code is deployed.
Cloud cost is treated as a code bug. Just like syntax bugs, logic bugs, and security bugs — this tool introduces financial bugs.
- Paste code into the web interface (Python, JavaScript, or Java)
- Click "Analyze"
- Receive a structured cost report with fixes
- 🔍 Static Pattern Detection: Uses AST/regex to detect cost-heavy patterns
- 💰 Cost Estimation: Estimates costs in ₹ per execution and monthly
- 💡 Fix Recommendations: Every issue includes a recommended fix
- 🖥️ 100% Local: Runs entirely offline, no cloud dependencies
- 🌐 Multi-Language: Python, JavaScript, and Java support
| Language | Patterns Detected |
|---|---|
| Python | API/DB calls in loops, N+1 queries, unbounded queries |
| JavaScript | fetch/axios in loops, MongoDB ops in loops, async fan-out |
| Java | Spring Data repos in loops, RestTemplate, JDBC, ObjectMapper |
| Operation | Unit Cost |
|---|---|
| API Call | ₹0.01 |
| DB Query | ₹0.002 |
Formula: per_execution_cost = unit_cost × iterations (default: 100)

Pattern: API call inside loop
Line: 14
Severity: High
Estimated Cost:
₹1.00 per execution
≈ ₹30.00 per month (daily runs)
Why this matters:
Each loop iteration triggers a paid API request.
Recommended Fix:
Use a bulk or batch API endpoint to reduce call count.
