Leadbomb
A capable developer can build a smaller, useful replacement (search + scraping + SMTP verify + CSV) in ~40 hours using existing open-source scrapers, but reproducing LeadBomb's full multi-source coverage, scale, and polish is non-trivial.

No open-source build does this yet
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
- Search public sources for businesses/accounts, scrape public profile/contact pages, verify emails via SMTP, deduplicate and store results, export CSV.
What it still won’t have
- Coverage of 15+ sources (minimal replacement implements only a few)
- Polished UI/UX and bulk search polish (pagination, credit system, team seats)
- Unlimited-scale scraping infrastructure and dedicated support
- Built-in AI query expansion and other Pro features
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hosted LeadBomb replacement using Python FastAPI, Playwright for scraping, Postgres for storage, Redis + RQ for background jobs, and a minimal React UI. Core features in scope: run keyword+location searches, scrape results from Google Maps + LinkedIn + Instagram (one social), extract emails, run SMTP verification, deduplicate, store leads, and export CSV. Out of scope: implementing 15+ source connectors, AI query expansion, billing/credits, team seats, and advanced UI polish. Include error handling, retry/backoff for scrapers, rate-limiting, basic tests for scraping and verification flows, and a Docker Compose setup for local deployment.

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.
