How much would it cost?

Estimate the AI API cost to build any GitHub project from scratch

Try it with ($20K reference project)

How does this work?

Anthropic's Claude C Compiler project gives us a real-world data point: 100K lines of Rust cost $20K in API usage (2B input + 140M output tokens across ~2,000 sessions).

We use this ratio to estimate the cost of any GitHub repository. We fetch the repo's file tree and language breakdown via the GitHub API, then apply token-per-byte multipliers adjusted for language complexity.

The estimate represents the cost of AI-generating the entire codebase from scratch — not the cost of using AI as a coding assistant. Actual costs vary based on project complexity and development approach.
