## Context

**Moz Pro** — Track selected keywords and audit one owned site without recreating Moz's link index. It currently costs $49/mo.

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Moz Pro, track selected keywords and audit one owned site without recreating Moz's link index. The hard boundary is proprietary link index, keyword data, scoring, education, and campaign history, plus proprietary web index and data acquisition.

This brief describes a focused, single-operator replacement for the part of Moz Pro that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

## What you are building

Track a user-supplied keyword set, collect permitted search-result snapshots at low volume, audit one owned site, and show trends without pretending to recreate a commercial link index.

- Automate a bounded research or reporting workflow using permitted data sources.
- A responsive interface with real empty, loading, success, and error states.

## Requirements

### Functional

- Self-hosted server.
- PostgreSQL.
- Scheduled worker.

### Data and integrations

- Approved search-data API or manual imports.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

### Non-functional

- Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
- Security: server-side secrets, validated input, and no credentials in the client bundle.
- Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
- Portability: the operator can export their data and leave without losing it.

## Implementation brief

Build a closest honest personal substitute for Moz Pro in an empty repository.
Use Python 3.12, FastAPI, PostgreSQL, Playwright, and a small React frontend; do not offer alternative stacks.
The core loop is: track a user-supplied keyword set, collect permitted search-result snapshots at low volume, audit one owned site, and show trends without pretending to recreate a commercial link index.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create projects with domains, keywords, target country, language, device, and tags.
Fetch rankings only through the configured compliant API and enforce a daily budget.
Store raw result snapshots and normalized positions so every chart is auditable.
Display current rank, movement, best rank, URL changes, and a compact SERP history.
Import backlink and keyword files from third-party tools without claiming independent coverage.
Add scheduled runs, failure alerts, CSV export, retention settings, and database backups.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out building a general web crawler or backlink index.
Deliberately leave out circumventing search-engine access controls.
Deliberately leave out traffic estimates presented as observed first-party data.
Finish by running the tests and listing the exact commands used.

## Delivery standard

- Inspect the repository first, then write a short implementation plan before writing code.
- Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
- Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
- Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
- Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
- Add structured logs around every external call and return actionable errors without leaking sensitive details.
- Write unit tests for the core logic and one automated test of the main user journey.
- Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

## Acceptance criteria

- [ ] A clean install starts the app using only the README and .env.example.
- [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
- [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
- [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
- [ ] Tests, type checking, linting, and a production build all pass with no ignored failures.
- [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

## Non-goals

Do not build these, and do not claim to have replaced them:

- Proprietary link index, keyword data, scoring, education, and campaign history.
- Planet-scale crawl index.
- Backlink graph.
- Clickstream estimates.
- The useful dataset is owned, accumulated, or expensive to reproduce.

## What you still own after launch

- Secure credentials, rotate secrets, and handle provider rate limits.
- Run migrations, backups, restores, and dependency updates.
- Test the critical journey after every model, API, or hosting change.
- Monitor failures and fix the edge cases a first prompt will miss.

## Risk

**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.

## Prior art

Working open-source software you can read, fork, or borrow from before starting:
