10 Passive Income Ideas for Developers in 2026

Let's be honest: trading time for money has limits. Even senior developers earning $200K+ eventually hit a ceiling. Passive income changes the equation—you build once, earn forever.

Here are 10 realistic passive income ideas for developers, ranked by effort required and income potential.

1. Idlen: Earn While You Code (Easiest)

This is the lowest-effort passive income available to developers. Idlen displays relevant developer ads during your AI tool usage:

• Works with ChatGPT, Claude, Cursor, VS Code, and more
• Non-intrusive sidebar or toast ads
• No extra work required—just code normally
• Cash out when you hit $50

Why it works: You're already using AI tools. Idlen monetizes the waiting time that would otherwise be wasted.
