CRM and sales decision
ProspectZero
A technical user can reproduce a narrow, self-hosted workflow (signal scraping → LLM message → automated LinkedIn sends → inbox) using existing open-source projects, but matching ProspectZero's full managed product, polish, and safe LinkedIn automation at scale is nontrivial.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All ProspectZero alternatives, with the arithmetic →
What a replacement has to do
- Detect people engaging with target LinkedIn content → collect prospect records → generate personalized outreach via an LLM → send outreach via automated LinkedIn agent → capture replies in a unified inbox
What it still won’t have
- polished UX and onboarding flows
- reliable, maintained LinkedIn automation at scale and ongoing anti-bot handling
- commercial support and SLA
- built-in team management, analytics dashboards, and account-level reporting
- legal/compliance guidance for LinkedIn automation
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted signal-based LinkedIn outreach service using Node.js + TypeScript, Postgres, Puppeteer (or Playwright), and OpenAI (or a configurable LLM). In scope: 1) a crawler that finds profiles engaging with given LinkedIn posts/hashtags and extracts profile URLs; 2) a Postgres schema with dedupe, tags, and simple filters; 3) an LLM-based message generator endpoint that templates & personalizes messages; 4) a headless-browser worker that sends connection requests or messages on LinkedIn with rate limits, exponential backoff, and logging; 5) a polling-based inbox collector that reads recent conversations and stores replies threaded to prospects; and 6) a minimal web UI to queue targets, view inbox threads, and see send status. Out of scope: multi-seat billing, advanced analytics dashboards, paid integrations, and compliance/legal advisory. Require: robust error handling, retry policies, tests for crawler, sender, and message-generator, config-driven rate limits, and secure storage of credentials.

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.
