How to pick an idea you’ll actually finish

Pick a problem you have. You’ll know what “good” looks like, and you’ll keep using it after launch.

Start with the weekend size. A small app you ship beats a big one you abandon. You can always grow it.

Decide how it earns before you build. A one-time price or a small subscription shapes what you build first.

Then write a short spec with the PRD generator and hand it to your agent with a kickoff prompt.

Made by Eddie

Stop checking on your agents.

Building your idea with Claude Code or Codex? Eddie keeps an eye on your agents while you do.

Questions.

What is a good first vibe coding project?

A small tool for a problem you have, that one person can finish in a weekend: a tracker, a calculator, a simple booking page. The “Weekend” filter shows those.

Can I build these with Claude Code, Codex or Cursor?

Yes. Each idea is sized for one person working with an AI coding agent. Copy the build prompt or turn the idea into a PRD first for better results.

Can I make money from these apps?

Each idea lists a simple way it could earn, like a one-time price, a subscription or credits. Validate with a few real users before you build the paid parts.
