Vibecoding Project Ideas When You're Out of Ideas

The hardest part of vibecoding isn't the AI — it's staring at a blank prompt box wondering what to build. Here's a list of ideas sorted by difficulty, plus a rule for picking the right one.

Start Here (Under 10 Minutes)

These are small enough to finish in one sitting, which matters more than people think — a finished tiny project teaches you more than an abandoned big one.

• Tip calculator — bill amount, tip percentage, split by people
• Countdown timer — pick a date, watch it tick down
• Password generator — length slider, character type toggles
• Unit converter — length, weight, temperature
• BMI calculator — with a visual health range

Every one of these has a clear "done" state. You know exactly when you're finished, which means you'll actually finish it.

Level Up (10-20 Minutes)

Once the basics feel easy, add persistence and multi-step state:

• Habit tracker — a GitHub-style contribution grid stored in localStorage
• Kanban board — drag-and-drop columns
• Poll maker — create a question, vote, watch percentages update live
• Expense tracker — categorize spending, show a running balance
• Snippet manager — save and search code snippets with tags

These force you to think about data shape before you think about UI — what does a "habit" or a "task" look like as an object, and how does it change over time.

Push Further (20+ Minutes)

• Mini spreadsheet — cell references, a real formula parser
• Step sequencer — synthesized audio in the browser, no samples
• Cellular automaton — Conway's Game of Life with pattern presets
• Unbeatable tic-tac-toe — implement minimax yourself instead of asking the AI to

This tier is less about the UI and more about an algorithm or a small engine sitting underneath it. That's usually where the actual learning happens.

How to Pick

Don't pick the idea that sounds most impressive. Pick the one where you can already picture the finished screen in your head — that's the signal you have enough context to write a good first prompt (see the three-prompt rule if you're not sure where to start).

If you genuinely can't picture it, that's fine too — go smaller. A finished stopwatch beats an abandoned SaaS dashboard every time.

Every project on this site was built from a single starting prompt — check the "Built with this prompt" card at the bottom of any project demo to see the exact wording that kicked it off, or start your own in Project Starter.
