Snov.io

A competent developer can build a useful subset (find+verify+send) in about a week, but they cannot reproduce Snov.io’s proprietary, reverified B2B database, warm-up pool, broad integrations, and enterprise deliverability infrastructure; keeping the paid product makes sense if you need those assets.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.

What a replacement has to do

Discover prospects, verify contact emails, store prospects, and send personalized email outreach sequences.

What it still won’t have

Access to Snov.io’s proprietary, extensive B2B contact database and monthly reverification process
Large warm-up pool, premium warm-up infrastructure, and shared deliverability infrastructure
Built-in LinkedIn automation extension and browser extension convenience
Hundreds/thousands of pre-built integrations and enterprise support/implementation services
Scale, fraud prevention, and deliverability monitoring baked into the vendor platform

What remains hard

Runnable build prompt

Build a minimal self-hosted lead discovery + verification + email outreach service using Postgres, a Node.js (Express) API, and a React admin UI. In scope: (1) prospect discovery endpoint that scrapes company pages and accepts CSV uploads, (2) email pattern generator and SMTP/SMTP-probe verification job, (3) prospect storage with deduplication and quota counting, (4) campaign engine to send templated personalized emails and schedule follow-ups via a transactional SMTP provider (Mailgun/SendGrid), (5) simple dashboard to view prospects, campaign status, bounces, and replies (webhooks). Out of scope: building a proprietary global contact database, LinkedIn browser extension, shared warm-up pool, or full deliverability analytics. Include error handling, background job retrying, basic automated tests for core endpoints, and deployment scripts (Docker + single cloud VPS).

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.
