Solo Founder (Vibe Coded SaaS MVP)
‍Stage: Private beta with test users
‍Challenge: Users reported “it doesn’t work” errors — but the founder couldn’t reproduce or pinpoint the issue due to a lack of proper error logs.

Without clarity, the founder had two bad options:

- Open a support ticket for every vague user report (burning hours + subscription credits)
- Keep guessing at fixes, losing momentum and frustrating testers.

With Error Heatmapping turned on, every error was automatically tracked and tagged to the exact page and workflow step.

- Within 24 hours, the founder saw a clear spike in failed submissions on the “Invite Teammate” form.
- The heatmap highlighted the missing field validation.
- The founder fixed the workflow himself in less than 30 minutes — without calling in DevCode911 engineers.

✅ Issue Resolved Independently by founder due to clear error maps provided in his subscription.
✅ 5+ Engineer Hours Saved in that first month.
✅ Higher Confidence: Founder knew exactly what was breaking, instead of flying blind.
