Bring me the
broken build.
Paste an error, share a code snippet, or check a public website. DebugSmith checks common failure patterns and gives you likely causes, suggested changes, and a checklist to test them.

Show us what broke.
Paste the evidence. DebugSmith triages the failure, inspects a public URL when provided, and builds suggestions for you to review and test.
The method
Repair, not guesswork.
Evidence first
Errors, logs, URLs and the smallest relevant code snippet. No vague “try this” roulette.
Understand the failure
Use pattern-based checks to identify likely explanations and the evidence needed to narrow them down.
Smallest safe fix
Get a focused patch, not 1,000 lines of unrelated AI-generated churn.
Prove it
Every repair packet ends with checks for the original failure and nearby regressions.
Built for the ugly part
Your AI builder got you to 80%.
DebugSmith gets you unstuck.
✕ “It works in preview but dies in production.”
✕ “The extension loaded yesterday. Now the service worker is dead.”
✕ “The agent loops, hallucinates a tool result, or silently stops.”
✕ “I changed one thing and the entire page layout exploded.”
✕ “The AI keeps rewriting code instead of finding the bug.”
Free tools, ready now
Start with a useful diagnosis.
Free
Check common errors without an account.
- Known error patterns
- Text and code attachments

Everything available in the Repair Lab is free. No account, credit card, or subscription required. Deeper AI reports will be offered separately when ready.
Maintained with care
Clear about what we know.
We review official framework, AI-provider, and payment documentation periodically to guide tested updates. Each report uses the evidence you provide; it does not automatically browse the web or verify the latest version of every dependency.
Include your framework and package versions for more useful advice. Suggested changes still need review and testing in your project.
Release 1.2.1 · free launch September 10, 2026.
Free field guides
Get unstuck before you ship.
Short, practical notes for the failures we see most often. Use them on your own, then bring the evidence to the Repair Lab when you need a second set of eyes.
