Not another AI model guessing at your code.

Using probabilistic AI to find a problem created by a probabilistic AI guarantees more drift.
Applying more agents doesn't solve the gap in a handoff.

DETERMINISTIC

DETERMINISTIC.
NO GUESSING

Same repo, same score, every time. Every dimension is rule-based, not an LLM's best guess — scan a repo twice and get the same answer twice.

NO TOKENS, NO PROMPTS

NO TOKENS,
NO PROMPTS

Nothing here calls an LLM. No API costs per scan, no context window to run out of — which is exactly why this can stay free instead of metered.

VERIFIABLE, NOT NARRATED

VERIFIABLE,
NOT NARRATED

Every finding is a file and a line, not a paragraph of AI prose. Click through to GitHub and check it yourself — nothing to take on faith.

A STANDARDIZED SCORE WEIGHTED BY FIX HOURS

A STANDARDIZED SCORE
WEIGHTED BY FIX HOURS

A WEIGHTED SCORE, NOT A GUESS

A single Production Drift Ratio (0–1), banded from Low to Severe. Two repos, or the same repo six months apart, are actually comparable.

PINPOINTED LOCATION, FILE AND LINE, EVERY TIME

PINPOINTED LOCATION,

FILE AND LINE, EVERY TIME

Tells you exactly where the code has drifted from intent or standards, line by line, so you don't have to go searching.

WHERE THE REPO DRIFT IS HEADING OVER TIME

WHERE THE REPO DRIFT IS

HEADING OVER TIME

The full history gets scored, not just today's code — see precisely which commit opened the gap, and whether it's closing or widening.

HOW MUCH TIME DRIFTDETECTOR JUST SAVED YOU

HOW MUCH TIME DRIFTDETECTOR

JUST SAVED YOU

Tells you how many hours the one scan just saved you and how many issues can be auto-fixed (coming in ReWeaver) versus what needs human judgment.

Your code stays private.

A repository's code goes from GitHub directly to the scanner without passing through the browser, streams into the scanner’s temporary memory, and is never written to disk; the clone used for charting fetches commit metadata only — no file contents — and the scan stops rather than continues if a single file blob reaches disk. 


Nothing about a private scan is kept or left behind: no cached clone, no cached scores, no name, no score, no report.


The only stored element is your GitHub token, encrypted, until you disconnect — you choose which repositories the app may read, and disconnecting, or revoking on GitHub, ends that.
