A small, personal-use prospect workspace. It sends one search at a time to the bundled gosom/google-maps-scraper worker, waits for its asynchronous job to finish, filters places already in the local catalogue, and presents the remaining places for human review.

The interface is intentionally focused: discovery, run progress, catalogue search, and review status. It does not send outreach, create a CRM campaign, or make an AI decision. The opportunity score is a transparent triage hint based on fields returned by Maps (for example, a missing website and a listed phone number); you make the final review decision.

Start the stack

cp .env.example .env
docker compose up -d --build

Open http://SERVER:8000 for ProspectOS. The Maps worker is available on http://SERVER:8081 for its one-time setup.

Connect the Maps worker

Open port 8081 in a browser on your private network.
Use the worker's admin screen to create an API key for this local app.
Put that key in .env as GMAPS_API_KEY=....
Restart the app with docker compose up -d --build and reload ProspectOS.

The app calls /api/v1/scrape to queue a job and /api/v1/jobs/{id} to poll it. Jobs are deliberately asynchronous because a Maps scrape can take several minutes. A run that loses its worker connection is shown as failed with a specific error rather than remaining stuck forever.

Configuration

Variable	Default	Purpose
`HOST_PORT`	`8000`	Host port for ProspectOS
`GMAPS_HOST_PORT`	`8081`	Host port for the Maps worker admin UI
`GMAPS_API_KEY`	empty	API key created in the Maps worker admin UI
`GMAPS_REQUEST_TIMEOUT`	`300`	Per-job scraper timeout in seconds
`GMAPS_POLL_SECONDS`	`2`	Poll interval while a job is running
`DISCOVERY_BACKEND`	`gmaps` when `GMAPS_URL` is set	Set to `browser` only for the old public-search fallback

The app stores its catalogue in the prospect_data Docker volume. The worker stores its own job data in gmaps_data; keep both volumes if you want to retain history. To inspect status:

docker compose ps
docker compose logs --tail=100 app
docker compose logs --tail=100 gmaps

Local fallback mode

For a quick local smoke test without the Maps worker:

DISCOVERY_BACKEND=browser GMAPS_URL= docker compose up -d --build

This uses Playwright against public search engines, keeps the same catalogue and review UI, and does not bypass CAPTCHAs or other access controls.

Data and review behavior

Each saved place includes its name, Maps link, website (when present), root domain, address, phone, category, rating, review count, public emails returned by the worker when explicitly enabled, source ID, and raw result JSON. A place with no website is still retained using a stable maps:<place_id> catalogue key, so it can be reviewed as a potential website opportunity. Existing websites are deduplicated by root domain.

Email extraction is off by default in the UI. If you enable it for a run, the worker may visit the public business website; expect a longer run and review the resulting provenance before using any contact information.

Tests

python3 -m py_compile api/server.py
node --check web/app.js
python3 -m unittest discover -s tests -q

This project is packaged for personal research. Public availability does not override a website's terms, robots controls, or applicable privacy law; keep searches small, use the worker only on data you are permitted to collect, and do not turn the review screen into unattended outreach.
