ProspectOS Review
Open-source lead prospecting CRM with Google Maps and Instagram scraping
CRM · Open Source · OPEN SOURCE
Overview
ProspectOS is a local lead-prospecting tool for agencies and freelancers who sell websites or digital services to small businesses. It scans Google Maps by niche and city (or by pin and radius), checks each company's website to separate no-site from slow-or-insecure-site, scores the results, and generates an AI-written outreach message plus a PDF diagnosis per lead, all tracked in a visual kanban CRM. The stack is Flask, React 19, TypeScript, and SQLite, runs locally on Windows, and the repo shows 230 passing tests. The honest catch is in the project's own warnings: it is a scraping tool, Google Maps and Instagram scraping can violate those platforms' terms, and the Instagram module logs in with a personal account via instagrapi, which carries a real risk of checkpoint or ban. The README recommends a secondary account and moderate use. MIT-licensed with 206 stars, it is a working codebase for learning and prospecting at small scale, sold to nobody and hosted by you, with the compliance question deliberately left in your hands.

Hands-on notes
The README is unusually candid: a dedicated 'before you use' section spells out that the tool scrapes Google Maps and Instagram, that Instagram access uses your personal account through instagrapi with a documented risk of security checkpoints or bans, and that the WhatsApp cockpit only passively reads a chat window you open yourself. That transparency makes evaluation easier, since the operational risks are the product's most important features. All claims here come from the repository documentation; we have not run prospecting campaigns with it.
The scope is deliberately narrow and local: businesses without websites or with poor ones, approached via WhatsApp with an AI-drafted message and a PDF diagnosis. For a web-design freelancer that is a genuine end-to-end workflow. The Instagram module is optional but account-risk-bearing, and the tool runs on your machine by design, so there is no SaaS convenience layer or team features.
Verdict
A working, well-tested local prospecting tool with unusually honest documentation about its scraping risks. Suitable for individual freelancers who accept the terms-of-service exposure; not a team tool, and not compliant-by-design with Google or Instagram ToS.
