Who this is for

Beginners whose app worked before an AI edit and who need a repeatable way to investigate.

Before you start

Comfort opening a project and its preview. No previous debugging experience required.

How long it takes

The in-app lesson estimates total about 18 minutes. Repeat exercises at your own pace and allow separate time for the optional project. Finishing a drill is different from being ready to operate a production app.

The actual curriculum

These titles and summaries come from the same lesson catalog used in the app.

Debug without fear

  1. 1.

    Read the error first · ~3 min

    Turn a wall of red text into the clue that solves the bug.

  2. 2.

    Check what changed last · ~3 min

    Find the prime suspect before anyone rebuilds half the app.

  3. 3.

    Reproduce the bug · ~3 min

    Turn “it sometimes breaks” into a recipe the agent can fix.

  4. 4.

    One change at a time · ~3 min

    Keep changes small enough that you always know what did what.

  5. 5.

    The art of the rollback · ~3 min

    Escape a fix-loop in one minute instead of digging for an hour.

  6. 6.

    Verify the fix · ~3 min

    Prove a fix worked — and catch what it quietly bent next door.

Put it into a small project

Use a copy of a small app, introduce an incorrect import, record the browser error, then fix and retest it. Keep the working version recoverable.

This is a suggested practice assignment, not a claim that VibeGym automatically creates or hosts the app for you. Keep a working checkpoint and show the result to someone else before increasing the scope.

Access and next steps

The public sample and guides are free. All 36 in-app lessons are also free with an account, alongside one standard training session per day. Paid plans add unlimited training, mistake review and the full project challenge. AI coding tool subscriptions and hosting are separate. See plans and prices.
