AI is getting smarter.
One definitive perspective.
We do not measure raw typing speed. We evaluate the judgment, taste, and system instincts that separate real builders from code generators.

Replaceability Index
Three steps. One definitive perspective.
We do not measure raw typing speed. We evaluate the judgment, taste, and system instincts that separate real builders from code generators.
Answer thoughtful developer questions
A fast, honest questionnaire exploring your real responsibilities: edge cases, system trade-offs, debugging instincts, and human judgment AI cannot emulate.
Connect your proof of work
Optionally link GitHub, public repositories, and your coding profiles. We look at architectural breadth, commit consistency, and real-world system complexity.
Meet your developer identity
Unlock your Replaceability Index, claim your developer tier, and export a collectible dossier badge engineered for friendly peer comparison.
Your score, explained.
A single percentage cannot tell your whole story. We unpack your Replaceability Index into five deterministic dimensions—evaluating where your human judgment delivers asymmetric leverage.
“A lower index indicates deeper human judgment, architectural taste, and edge case resilience that current frontier LLMs fail to autonomously replicate.”
Technical Depth & Abstraction
Memory models, distributed state, concurrency & zero-cost primitives
Real-World Project Battle Scars
Production scale, failure modes, migration debt & live refactoring
Engineering Rigor & Practices
Test determinism, fault isolation, automated verification & observability
AI Proficiency & Orchestration
Surgical context injection, spec rigor & human-in-the-loop verification
Beyond the questionnaire.
Real proof of work.
Self-reported answers provide the foundation. Optional public GitHub telemetry unlocks deep architectural signal—grounding your score in real commits, tests, and production code.
Where true engineering instincts stand.
Real engineers tested against system failure scenarios, high-load edge cases, and human architectural synthesis.

Clarity before calculation.
How is the Replaceability Index calculated?+
Our model doesn't test syntax trivia that LLMs excel at. Instead, we measure ambiguity resolution, capacity planning under partial failure, latency-cost balance, and taste in system modularity.
Do you store or inspect private repositories?+
No. GitHub verification is entirely optional and performs local client-side AST metadata verification of architectural complexity. We never store source code, private keys, or personal tokens.
Is this project serious or satirical?+
A deliberate mixture of sharp tongue-in-cheek developer humor backed by rigorous systems design benchmarking. It highlights the irreplaceable human dimension of software engineering.
