The Debugging Problem That's Costing You Money

Every developer knows the painful fix-run-fix-run cycle. Here's what it's really costing you.

Traditional Debugging

The expensive way everyone does it

Run 1:
❌ NameError at line 45
Fix → Run again
Run 2:
❌ TypeError at line 78
Fix → Run again
Run 3:
❌ KeyError at line 102
Fix → Run again
Run 4-7:
❌ 4 more errors discovered
Keep fixing one at a time...

How We're Fundamentally Different

We catch bugs before your users do. Monitoring tools catch them after.

Traditional Monitoring

Sentry • Datadog • Rollbar • New Relic

After Production

Only catches errors when users trigger them

Reactive

Wait for bugs to happen in production

Runtime Errors Only

Misses syntax, logic, and edge case errors

User Impact

Users experience errors before you know about them

$99-$500/month

Ongoing monitoring costs

Before Production

Proactive

35+ Error Types

Syntax, logic, security, performance, and more

Zero User Impact

Users never see bugs in the first place

Real-World Use Cases

See how DevTraceTool solves common debugging challenges that waste developer time

Debugging Unfamiliar Codebases
The Problem:

Inherited a legacy project with zero documentation?

The Solution:

Run one trace and see ALL problems immediately. No more guessing where bugs might be hiding.

Real Example:

1,387 lines of unfamiliar code → 32 relevant events showing all issues

Save hours of code exploration
Refactoring with Confidence
The Problem:

Worried your refactor broke something?

The Solution:

One trace shows ALL breaking changes across the entire codebase. Fix everything before committing.

Real Example:

Renamed a function → Found 7 places that need updates in one run

Zero regression bugs
Error-Tolerant Code Testing
The Problem:

Try/except blocks hiding bugs in production?

The Solution:

Capture ALL exceptions, even caught ones. See what errors your code is silently swallowing.

Real Example:

Found 3 caught exceptions that indicated data quality issues

Better error handling
Multiple Code Paths
The Problem:

Need to test if/else branches and edge cases?

The Solution:

All branches traced in one execution. See which paths have errors without manual testing.

Real Example:

5 different code paths traced → Found errors in 2 untested branches

Complete test coverage

"Reduced our debugging sessions from 7 runs to just 1 trace"

Traditional debugging required multiple fix-run cycles. Now we see all errors at once, fix them together, and move on. Saves us hours every week.

Real-world usage: 7 bugs found in 2 seconds
"Our LLM token costs dropped by 98%"

We were spending $1.47 per debugging session sending 49,000 tokens. DevTraceTool reduced that to $0.03 with just 1,000 tokens. The ROI is incredible.

Saving $1,728/year on API costs alone
"Perfect for understanding legacy codebases"

Inherited a 1,387-event Python project with zero docs. One trace showed us all 32 critical issues. We fixed everything in one afternoon instead of spending weeks exploring.
