Tiny tokens.
Big ships.
Track your AI coding burn, compete in verified cost-per-fix challenges, and learn the workflows behind top builders.
Who ships the most for the least?
Ranked by VES — Verified Efficiency Score (verified fixes ÷ AI cost USD). Lower spend, more fixes = higher rank.
Provider or device-synced — measured at the source.
Submitted by the builder, not yet confirmed.
VES = verified fixes ÷ AI cost (USD). Higher is better. Verification badges: Provider-synced > Device-synced > Estimated > Self-reported.
Compete on verified efficiency.
Every challenge is judged by VES — independently verified fixes divided by your total AI spend. No vanity metrics.
Fix a real Lighthouse regression
Ship a verifiable fix that improves Lighthouse score by ≥10 points. Claude Code only.
Zero-token refactor
Refactor a component with the lowest possible token spend. VES judged.
Bug hunt: cost < $0.10
Find and fix a verified bug for under 10 cents of AI spend.
# Verified Efficiency Score
def score(fixes: int, cost: float) -> float:
return fixes / cost
# Example from this week
score(fixes=847, cost=4.20) # → 201.7
The builders setting the pace.
Each card shows verified efficiency over the last 7 days. Badges reflect how usage data was collected.
Proven workflows from top builders.
Read-only guides, config packs, and executable bootstraps — all verified by VES score. No black-box prompts.
Low-Cost Debugging
A step-by-step workflow for debugging with minimal token spend. Read-only guide.
Claude Code Review Loop
Pre-configured review loop that cuts review token cost by ~40%.
Codex Repo Bootstrap Pack
Executable scaffold pack for starting new repos with Codex-optimized structure.
Built for builders who own their data.
We track efficiency metrics — never your code, prompts, or secrets. The collection spec is public and auditable.
No raw prompt storage
We never store, process, or transmit your source code, prompts, or responses. Zero.
Device-local collection
Usage data is aggregated on your machine. Only token counts and cost estimates leave your device.
Transparent verification
Every badge shows exactly how it was verified: Provider-synced, Device-synced, Estimated, or Self-reported.
Open collection spec
The collector spec is public. Anyone can audit what fields are collected and what stays local.
