You're in Claude Code. You've typed "make it better" for the 11th time. Claude rewrites your entire module. Again. 2,000 output tokens.</p> <p>Multiply that by 30 days. Check your bill. $47.</p> <p>Your reaction: "That can't be right."</p> <p>Narrator: It was right.</p> <h2> Chapter 2: The Dashboard Nobody Asked For </h2> <p>I could have just... spent less. But I'm a developer. So instead I built a pixel bead board. Think Perler beads meets NES retro gaming meets existential dread about AI costs.</p> <p>Every token becomes a colored pixel. Claude = coral. GPT = green. Gemini = blue. Light pixels = input tokens, dark pixels = output (3-5x more expensive).</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fgwlwas3kgh1f0tyablxo.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fgwlwas3kgh1f0tyablxo.png" alt="ohmytoken dashboard" width="800" height="446"></a></p> <h2> Chapter 3: The Cat Head </h2> <p>You can pick board shapes: square, cat head, heart, star, mushroom. Fill patterns: spiral, rain, snake. When full, it saves as pixel art. Each cat costs about $0.80 in API fees. Beautiful and depressing.</p> <h2> Chapter 4: The 80% Problem </h2> <p>My board was 80% dark red. That meant 80% output tokens at $15/MTok vs $3/MTok input. Started asking for shorter answers. Cost dropped 30%.</p> <p>The dashboard paid for itself. Ironically.</p> <h2> Setup: 30 Seconds </h2> <p>Claude Code: 3 env vars. OpenClaw: 1 command. Any agent: 1 curl.</p> <p>Privacy: only token counts, never prompts. Open source.</p> <p><strong><a href="https://ohmytoken.dev" rel="noopener noreferrer">ohmytoken.dev</a></strong> | <strong><a href="https://github.com/0x5446/ohmytoken-oss" rel="noopener noreferrer">GitHub</a></strong></p> <p>Cat head optional but recommended.</p> ai showdev devtools llm
