Pick your bug's category
Seven common categories — logic errors, null references, async races, off-by-one errors, type mismatches, state bugs, and integration mismatches.
CURSOR / GITHUB COPILOT / REPLIT / LOVABLE COMPARISONS
Bug Fix Arena
Pick your bug's category and how far its cause spreads across your codebase, and get a scored comparison of how an agentic IDE agent, an inline copilot, and a prompt-to-app builder typically perform at identifying and fixing that kind of bug — based on a transparent rules table, not a live run.
- 7 bug categories × 3 scope levels
- Separate identify and fix scores shown
- All answers stay in your browser
Pick a bug category and scope, then click Compare tool categories to see the scored readout.
Best fit for this bug
How it works
Pick how far the cause spreads
Single file, a few related files, or cross-cutting across many files/layers — scope changes which tool category has the advantage.
Get a scored, reasoned comparison
Each tool category gets a separate identify score and fix score out of 10, based on a documented rules table reflecting how each archetype actually works — not a live run or random result.

Frequently asked questions
Does this run my actual bug through real AI tools?
No. Bug Fix Arena looks up a transparent scoring table based on the bug category and scope you select — it does not execute code or connect to Cursor, Copilot, Replit, Lovable, or any other tool.
Why do scores change with "scope"?
An agentic IDE agent can search across your whole repo and hold up as the cause spreads across files, while an inline copilot only sees what's open in the editor and a prompt-to-app builder works from your description — both lose accuracy as the true cause spreads further from what's visible or described.
Are these scores based on real product capabilities?
Yes — the scoring reflects each tool category's well-known, documented way of working (multi-file agentic search vs. single-file completion vs. prompt-driven regeneration), not fabricated benchmark numbers for specific products.
Should I only use the highest-scoring tool category?
Treat it as a starting expectation, not a rule — the actual outcome always depends on your specific codebase and how you describe the bug. Use the identify/fix breakdown to decide where to focus your own review.
How We Compare
| Feature | MVPHub | Running the bug through each tool manually | General crowd-sourced tool rankings |
|---|---|---|---|
| Scored by specific bug category and scope | Included | Not included | Not included |
| Separate identify vs. fix scoring | Included | Limited | Not included |
| Transparent, documented rules table | Included | Not included | Limited |
| Runs your exact bug for a real outcome | Not included | Included | Not included |
Running the bug through each tool manually gives a real result but costs setup time per tool, and general tool rankings don't account for bug type or scope. MVPHub gives an instant, reasoned expectation for your specific bug category before you decide where to spend that manual effort.
