Not a repo health-scorer — a reuse decision engine.
Every "is this repo any good?" tool grades maintenance. RepoHunter answers the question you
actually have: should I adopt this — for my project, on my machine?
A GO / MAYBE / SKIP call and a plan to do it — and now a skill your AI agent calls before it installs anything.
🔥 Every token spent regenerating code that already exists is wasted.
Regenerating a ~500-line module ≈ ~20,000 tokens all-in ≈ $0.04–$0.80cheap model → premium · all-in = the code plus the context & retries it takes to generate it
…now multiply that by everyone, every day ↓

A back-of-the-envelope — not a measurement. Every assumption is
shown so you can argue with it. Across the model tiers, the mid case is ~$80K–$1.6M/day
(≈ $29M–$584M/year) of compute burned re-writing code that already exists. That's the problem RepoHunter exists to kill.

Where this is headed: as AI agents write more of the code,
your agent calls RepoHunter automatically — an MCP server that checks before it installs. Same verdict, zero clicks.
Not another repo health-scorer
It answers the question you actually have
Every other tool tells you “is this repo well-maintained?” RepoHunter tells you
“should I adopt this — for my project, on my machine — and what will it cost me?”
🎯
An integration dossier
Relevance to your project, how to integrate, the enhancement you'd gain, build-vs-integrate, and a GO / MAYBE / SKIP call.
💻
Runs-on-your-hardware
A real resource-fit check plus a rough cost to integrate — tokens, time, agents. Nobody else does this.
📥
Ingest from anywhere
Drop a repo, search GitHub live, or paste a “top-10 repos” YouTube video — RepoHunter pulls the repos out.
🔒
Local-first & honest
Runs on your machine with a local model — no bill, no lock-in. It plans; it never installs behind your back.
🧭
Knows what kind it is
Classifies each repo and proposes the right move — integrate, add as a source, or just learn from it.
⭐
Promotes the author
Every link sends you to star the original. RepoHunter celebrates open source — it doesn't strip-mine it.
Low-carbon by default
The greenest code is the code you never regenerate
Every token an AI generates burns real energy — electricity and water in a data center.
When millions of us regenerate the same auth flow, the same RAG pipeline, the same library that
already exists, that's redundant compute for zero new value. RepoHunter finds what's already built,
so you don't reinvent — and don't re-burn.
💸
Fewer tokens, smaller bill
Adopting proven code beats regenerating it from scratch. You skip the compute — and the cost that comes with it.
🌱
Less compute, less carbon
AI inference runs on real power and cooling. Reuse simply avoids it. Think of it as recycling, for software.
🧬
Breaks the monoculture
AI reaches for the same ten popular libraries every time. RepoHunter surfaces the long tail — so we stop all building the same thing.
It's not about an exact number — it's that reusing proven code means you don't spend the time, cost, or energy of rebuilding it.
What reuse is worth — to you
Your inputs. Your math. We don't put a number on it — you do.
We won't invent a savings figure and paste it on a billboard. Put in your own reality
and watch the estimate move. Every assumption stays on screen — nothing hidden, nothing asserted by us.
🧮 What this calculator does
It estimates what you save by reusing existing code instead of rebuilding it from scratch — in three things you actually care about: your time, your money, and AI tokens.
🔥 Wait — what's a "token"?
AI models read and write in tokens — tiny chunks of text, about 4 characters each. It's the unit they're billed by. Every time an AI regenerates code that already exists somewhere, it burns tokens you pay for — for zero new value. Reuse the code and you skip the burn entirely.
👇 How to use it
Type in your own numbers below. The estimate updates live. We never assert a figure — the math is yours, and every assumption is shown. Save a token, save a tree. 🌳

illustrative rates ≈ Budget $2 · Standard $10 · Premium $40 per 1M tokens · all-in ≈ 40 tokens/line
Put in your numbers above — I'll do the math live.
Rough and illustrative — a way to reason about your situation, not a promise or a
claim about typical results. RepoHunter helps you find and vet what to reuse; the value depends entirely on
what you'd have built instead.
🔍 Don't trust us — validate it
Every number here comes from one short, transparent algorithm. Read it, download and run it,
change the assumptions — or paste it into any AI and ask it to poke holes. No trust required.
# all-in tokens = the code PLUS the context & retries it takes to generate it
tokens/month = reuses × lines × 40 # 40 ≈ 13 output tokens/line × ~3 overhead
$/year (tier) = tokens/month × 12 ÷ 1e6 × rate
# rate = $2 Budget · $10 Standard · $40 Premium per 1M tokens
ecosystem/day = AI-devs × redundant-lines/day × 40
A live RepoHunter score you can embed — and can't fake
One line in your README shows your repo's current RepoHunter verdict, straight from
live GitHub data. You embed it — but you can't edit what it says. That's the whole point: a badge
nobody can game is a badge worth trusting. Stale repo, honest badge.
Transparent score over live GitHub data — not a safety or security
rating (that layer ships only after we validate it). Public repos need no login; the badge updates itself.
Why it exists
A love letter to open source, disguised as a tool
Every week, thousands of people give away brilliant work for free — and most of it is never
found. Discovery rewards whatever's already popular, so two things waste away at once: great
projects die in obscurity, and the rest of us reinvent what already exists because we couldn't find it.
The whole digital world runs on maintainers nobody thanks. And now that AI writes more of the
code — reaching for the same ten popular libraries every time — the long tail of great,
perfect-for-you software is going dark faster.
RepoHunter pushes back. It finds the right code for you — underdogs included — tells you the
honest truth about whether it fits your project and your hardware, and sends the
credit home: every path ends at a ★ for the author. Reuse, with gratitude.
