Analytics and monitoring decision
Nightwatch
A small, useful rank-tracking + AI-visibility workflow can be built and self-hosted using prior open-source tools, but Nightwatch's proprietary long-term historical data, large localized access infrastructure, and SOC2/enterprise features are not reproducible by a lone developer, so keep paying for scale or build a limited in-house alternative.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Collect SERP HTML for keywords, parse positions and SERP features, store raw snapshots, run AI prompt queries against LLMs and detect citations, surface results in a dashboard and exportable reports.
What it still won’t have
- 54,000+ localized access points and their scale
- 13 years of historical ranking data
- Built, verified 99.9% accuracy and the proprietary infrastructure that claims it
- Built-in integrations, SLA, and enterprise features (SSO, dedicated infra, priority support)
What remains hard
- Proprietary data
Nightwatch is the only platform built on 13 years of ranking data that connects both — because AI cites what ranks.
- Infrastructure at scale
proprietary infrastructure of 54,000+ localized access points — not shared proxy pools — which is why accuracy reaches 99.9%.
First-year cost

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 2 seats.

Runnable build prompt
Build a self-hosted minimal SEO rank tracker in Node.js (Express) + Postgres + React. Scope: (1) a worker that fetches Google SERPs for a provided list of keywords+locations, stores raw HTML in S3-compatible storage, parses rank and SERP features into Postgres; (2) a background scheduler to run daily checks and support on-demand refresh; (3) an integration that sends a concise prompt to OpenAI (or configurable LLM) to simulate an AI answer for a keyword and stores whether the brand/domain is cited; (4) a lightweight React dashboard showing keyword positions, snapshot history, and CSV/PDF export; (5) a REST API to fetch keyword history. Out of scope: enterprise-scale geo-grid (54k nodes), multi-engine scraping at massive scale, and multi-year historical backfill. Include error handling for network failures, retries, basic rate limiting, unit tests for parsers, and end-to-end tests for the core worker and API.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
