Common questions

Is SigRank — AI Operator Benchmarking safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

SignalAF · SigRank web app

Browse AI operator token telemetry, explore personal profiles, and compare token-cascade metrics on signalaf.com.

[Live site](https://signalaf.com) · [Leaderboard](https://signalaf.com/board/all) · [Methodology](https://signalaf.com/methodology) · [CLI & MCP](https://github.com/SunrisesIllNeverSee/sigrank-mcp) · [Local setup](#local-setup)

This repository contains the Next.js application: the leaderboard homepage, operator profiles, Compare, Hall of Signal, editorial pages, accounts, billing, and server APIs.

Explore the site

Surface	What you can do
Leaderboard / homepage	Filter the field by window and platform; inspect RAW and derived metrics
Operator profiles	View personal stats, submission history, badges, and account settings
Compare	Examine two operators' telemetry and metric differences
Hall of Signal	Browse records and the badge directory
SigRank overview	Understand the measurement and enrollment flow
Field, Articles, Blog, Wiki	Read research, explanations, and metric definitions

Some features are gated; see Feature flags. This README describes the source tree, not a promise that every optional integration is configured on every deployment.

Get your own results

You do not need to clone this application to use it. Run the CLI/MCP package:

npx sigrank                       # inspect local usage in the terminal

npx sigrank enroll # bind your device using a Settings connect code npx sigrank submit --dry-run # inspect the payload without sending it npx sigrank submit # publish a signed snapshot

Sign in at signalaf.com to create a connect code. Claims for profiles from the original board require ownership verification through hello@signalaf.com.

What is measured

Four token pillars feed the cascade: input, output, cache-write, and cache-read. Yield is calculated as:

Υ = (cache_read × output) / input²

The server verifies and re-scores submissions. Leverage, Velocity, SNR, and 10xDEV describe token-processing patterns; they are not measures of model quality, work quality, productivity, or business outcomes.

Upsilon is the measurement engine; SigRank is the public leaderboard and proof surface on SignalAF. Protocol semantics belong to TTEOP. See the methodology and wiki for definitions and limitations.

Ranked telemetry does not require prompt text, responses, or source code. Submissions also carry identity, device/signature, platform, and report metadata; see the CLI privacy details.

Stack

Next.js 16 App Router, React 19, TypeScript (strict)
Tailwind CSS 3
Supabase (Postgres, Auth, Realtime)
Stripe Checkout, Billing Portal, webhooks
Upstash Redis for rate limiting (Supabase Postgres fallback)
zod, Node test runner, Vitest, Playwright

Local setup

Requires Node 22.x (engines in package.json, .nvmrc).

npm install

cp .env.example .env.local # optional; see Environment npm run dev # http://localhost:3000

Unconfigured local development can use snapshot or demo data on supported read paths. This is not live telemetry. Live board data, authentication, signed writes, and billing need their corresponding services configured. A configured database with no matching records returns an empty result rather than a fabricated operator history.

Scripts

Command	What it does
`npm run dev`	Start the dev server
`npm run build`	Build for production (`next build --webpack`)
`npm run start`	Serve the production build
`npm run lint`	Run ESLint
`npm test`	Run the Node test suites in `__tests__/`
`npm run test:ui`	Run Vitest component tests
`npm run test:canonical`	Check canonical ingest parity (MO§ES Υ 18436.98)
`npm run test:coverage`	Run `npm test` with c8 coverage
`npm run e2e`	Run Playwright tests (`e2e:local` targets localhost:3000)
`npm run verify`	Run `tsc --noEmit`, the canonical test, and `npm test`
`npm run db:parity`	Check local migrations against the remote ledger (`db:parity:ci` for CI)
`npm run snapshot`	Refresh the cold-store board snapshot
`npm run sitemap:validate`	Validate the sitemap (`:live` checks production)

Before opening a PR, run npm run verify and npm run build.

Environment

Copy .env.example to .env.local. It lists every variable with notes. Never commit values. Production values live in Vercel environment variables.

Variable	Used for
`NEXT_PUBLIC_SUPABASE_URL`, `NEXT_PUBLIC_SUPABASE_ANON_KEY`, `SUPABASE_SERVICE_ROLE_KEY`	Live Supabase reads and service-role writes. The server client needs all three.
`STRIPE_SECRET_KEY`, `NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY`, `STRIPE_WEBHOOK_SECRET`, `STRIPE_PRICE_*`	Billing and webhooks
`NEXT_PUBLIC_SITE_URL`	Stripe redirects and public URLs
`UPSTASH_REDIS_REST_URL`, `UPSTASH_REDIS_REST_TOKEN` (or Vercel's `KV_REST_API_URL`, `KV_REST_API_TOKEN`)	Shared rate limiter. Without Upstash, the limiter uses Supabase Postgres (`api_rate_limit_hit`, migration 0055), then a per-instance in-memory counter. Sensitive write routes fail closed.
`SIGRANK_RULESET`	Server-only RS.xx scoring overrides
`SIGRANK_API_KEY`	Trusted bulk-read key for the public API (`x-api-key`)
`SIGRANK_INGEST_WRITE`	`1` enables persistence of verified snapshots to the board.
`CRON_SECRET`	Bearer token for `/api/cron/recompute`
`NEXT_PUBLIC_POSTHOG_KEY`, `NEXT_PUBLIC_POSTHOG_HOST`, `POSTHOG_KEY`	Product analytics
`RESEND_API_KEY`, `*AGENTMAIL_API_KEY`	Contact form and exchange email
`ALGOLIA_`, `EXA_API_KEY`, `MOTHERDUCK_`, `AI_GATEWAY_`, `VERCEL_CLIENT_`, `SIGNALAF_LIVE_TOKEN`	Search, enrichment, analytics, AI gateway, Vercel integration, live demo
`NEXT_PUBLIC_REALTIME_ENABLED`	Set to `false` to disable live board updates

Feature flags

lib/features.ts defines the flags. All gated flags default to off and accept 1 or true.

Flag	Gates
`NEXT_PUBLIC_GATE_CHALLENGES`	Throw-down challenges. Also needs `NEXT_PUBLIC_GATE_ARENA`. Off: `/api/v1/challenges` returns 404.
`NEXT_PUBLIC_GATE_ARENA`	Challenge submission interface (required with the challenges gate)
`NEXT_PUBLIC_GATE_SIGNAL_DROP`	Weekly signal drop
`NEXT_PUBLIC_GATE_BRACKETS`	Blind bracket / Circle Wars
`NEXT_PUBLIC_GATE_TRADING_CARD_SPECIES`	Species badge on trading cards

Database and migrations

Migrations live in supabase/migrations/. Use that directory and npm run db:parity for the current schema and remote-ledger status rather than relying on a hard-coded migration count. Apply required migrations before deploying code that depends on them; review the pending SQL and target project first.

Row Level Security policies, seed data, and security tests live in supabase/. See supabase/README.md to run your own instance.

Project map

Path	Contents
`app/`	App Router pages and API routes
`app/api/v1/`	Public API: ingest, claim, devices, billing, metrics, leaderboard
`app/api/mcp/`, `app/api/plugins/sigrank/mcp/`, `app/api/exchange/mcp/`	MCP endpoints (main server, analyst plugin, exchange)
`app/exchange/`, `app/api/exchange/`	Contribution exchange UI and API
`components/`	UI components
`lib/board/`	Board reads: Supabase, snapshot, mock fallback
`lib/ingest/`	Payload parsing, signature checks, cascade materialization
`lib/analytics/`	Scoring engine and server-only ruleset boundary
`lib/exchange/`, `lib/exchange-gateway/`	Exchange server logic and portable gateway reference
`lib/infra/`	Supabase clients, Stripe, rate limiting, API gates
`supabase/`	Migrations, policies, seeds, SQL tests, edge functions
`__tests__/`, `e2e/`	Node, Vitest, and Playwright tests

Development conventions:

Pages are server components by default. Add 'use client' only for hooks, handlers, or browser APIs.
Keep RS.xx scoring configuration out of client code.
Avoid random values and wall-clock reads at module scope.

Deployment

Pushes to main deploy to Vercel (vercel.json). A daily cron calls /api/cron/recompute. Set environment variables in Vercel. An OpenNext Cloudflare path exists (npm run preview, npm run deploy, wrangler.jsonc).

Security

Report vulnerabilities privately. Email the maintainer or open a private GitHub security advisory. Do not file public issues for vulnerabilities. See SECURITY.md.
