Engineering intelligence · Local-first · Deterministic

The Carfax for code.

AI shipped your codebase. We tell you what's actually inside — before your acquirer, investor, or new hire finds out. We ran LuxScope against express — score 84/100, 25 findings across 56 risk files, plus 23 generated handoff documents. View the report →

Everything we build, in one place.

Infrastructure tools built for engineers. MIT where open, proprietary where not.

Intelligence. Delivered as a session.

Deterministic scanners for code, agent-readiness, and the media accessibility debt generic audits miss — each shipped as a scored, versioned report.

Codebase IntelProprietary

LuxScope

Know what breaks before you change it.

Know which files will break before you touch them. Identify the tech debt due-diligence will surface — before the investor does. Give a new hire a working mental model in one report instead of two weeks of context-gathering. Audit AI-generated code you didn't write and can't fully vouch for. LuxScope reads your codebase deterministically. It is local-first and sends no telemetry.

Sample: 40/100 · 27 files analyzed (SecGate, our own public repo)

$750 launch price (first 5 audits), then $1,500 · one-time

Agent ReadinessProprietary

LuxFaber

Know if AI agents can read your site.

AI agents and AI crawlers read public websites whether you designed for them or not. LuxFaber scores your site on agent-readiness: crawl accessibility, structured data, semantic HTML, content clarity, and determinism. It does not promise that any AI product will cite your site. Same input, same score every time — no LLMs in the scoring path.

Sample: 86/100 · 6 categories scored · stelnyx.com (our own site)

$499 launch price (first 5 audits), then $900 · one-time

Media AccessibilityProprietary

LuxAbility

Media & document accessibility scanning.

Deterministic scoring against WCAG 2.1 media and document criteria (1.1.1, 1.2.x, 2.4.2, 3.1.1) for the assets HTML scanners skip. Crawls video, audio, PDFs, Office documents, and image alt text — quantifies content accessibility debt in billable units, plus an unscored static-HTML code baseline. Same input, same score, every run. An automated scan is a prioritization aid, not a certification of ADA or legal compliance.

Sample: 51/100 · 13 pages crawled · 14 assets (fictional township fixture)

$750 launch price (first 5 audits), then $1,200 · one-time

What ships

One scan. One PDF report.

  • Deterministic score (0–100) + rule-versioned report
  • Risk-scored file list — what to touch first
  • Architecture map + dependency graph
  • Handoff documents generated from the codebase
  • 1 re-scan within 30 days
  • 1 walkthrough call of the findings, up to 60 minutes
  • PDF report
TurnaroundTypical: 5–7 business days
Data residencyDeleted the day of delivery
FormatHTML + PDF + JSON

Also free for engineering teams.

Two MIT-licensed CLIs we maintain alongside LuxScope. One command, no account, same scoring discipline — built for engineers who already own the codebase, not for buyers commissioning a review.

SecurityMIT · free · zero config

SecGate

One command. One report. One exit code.

$ npx @stelnyx/secgate

Runs Semgrep, Gitleaks, osv-scanner, Trivy, and npm audit in one command. Normalizes findings into one report and fails the pipeline on CRITICAL or HIGH. Aggregation is deterministic — same inputs produce a JSON-byte-identical report every run, locked by determinism + golden snapshot tests.

Sample: FAIL · 43 findings · risk 365 · 5 scanners (express-pin)

API SurfaceMIT · free · zero config

ApiGate

Every endpoint. Scored. One command.

$ npx @stelnyx/apigate .

Inventories every HTTP endpoint across Express, Fastify, NestJS, and OpenAPI specs. Classifies auth posture, diffs code vs spec, fails the pipeline on open writes. 100% static — no HTTP, no credentials, no running server. Same inputs → byte-identical report.

Sample: FAIL · 50/100 · 68 endpoints · 68 open · 0 auth-drift (express-pin)

LuxAbility + LuxFaber Audit

Both audits on the same domain

$1,100one-time

$1,100 launch price (first 5 audits), then $1,800

The LuxAbility and LuxFaber audits run together against one domain.

Scope: 1 domain. Scopes as listed for each audit.

Multi-domain or government-wide scopes: quote separately (from $2,500). A single city, county or agency with one domain pays the per-product price above.

We run the scan first. You pay when you get the report.

Free tools: SecGate and ApiGate, MIT-licensed CLIs on npm. Scan data from audits is deleted after delivery on request.
