StackGap
Delivers a CSV of local businesses with no live chat widget on their site, $1.20 per lead.
Tell it who you sell to and where; it scans local business websites for known chat-widget scripts (Intercom, Tidio, Crisp, Drift, Zendesk and others) and emails a CSV of only the businesses with none installed, within 24 hours. It costs $1.20 per lead, $120 for 100, one-time, with bad leads replaced free. A free weekly email also sends one sample lead plus a ready-to-send cold-pitch script.

What holds up
- +$1.20 per lead, one-time, versus the $295+/month tech-lookup tools it compares itself against
- +Every lead ships with contact details and the confirmed chat-widget gap, ready to pitch same day
- +Bad leads get replaced free — you're not stuck paying for a wrong match
- +Free weekly email gives one real lead plus a cold-pitch draft, no purchase required
Mind the limits
- −Checks only for known chat-widget scripts — a tool it doesn't recognize could slip through as a false lead
- −"No chat widget" only confirms a gap, not that the business wants or can afford one
