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 includes discovery, run progress, catalogue search, website health and email evidence, explainable scoring, domain ideas, suppression, CSV export, scheduled runs, rescans, and human review. It never sends outreach automatically. Optional AI can analyse a prospect and draft a subject/email from supplied evidence and your offer; you edit and approve the draft yourself.

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 if you want to inspect its native Web UI.

How the worker connects

No Google Cloud API key is required. The bundled standard worker exposes a local REST API on the Docker network, and ProspectOS calls it directly.

The app uses /api/v1/jobs to queue a search, polls /api/v1/jobs/{id}, and downloads /api/v1/jobs/{id}/download when the job finishes. Jobs are deliberately asynchronous because a Maps scrape can take several minutes.

Only set GMAPS_API_MODE=saas and GMAPS_API_KEY=... if you deliberately replace the bundled worker with gosom's optional SaaS edition.

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_MODE`	`standard`	`standard` for the bundled worker; `saas` only for the optional SaaS API
`GMAPS_API_KEY`	empty	Not required in standard mode; only used in SaaS mode
`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 bounded public-search fallback
`AI_BASE_URL`	empty	Optional OpenAI-compatible `/chat/completions` endpoint
`AI_API_KEY`	empty	Optional provider key; keep server-side
`AI_MODEL`	empty	Model name used for evidence-grounded drafts

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 available, 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 always enabled. The worker may visit each public business website found by Maps; expect longer runs and review the resulting provenance before using any contact information. It does not invent email addresses when none are published.

Website scans are bounded and SSRF-safe. A scan records HTTP status, final URL, latency, HTTPS/TLS, title, technology hints, contact-page emails, and errors. Use /api/prospects/{id}/scan for a manual rescan. The explorer's “Draft AI email” action calls /api/prospects/{id}/message; it requires the optional AI variables above and accepts your exact offer/instructions (for example, the Gold Plus R119/month plan and a free rebuild). Suppressions are enforced before new records are saved and can be managed through /api/suppressions.

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.
