Comparison

Facebook group and Nextdoor monitoring tools, compared

Seven ways to hear about a neighbor asking for your trade. We make one of them. For every other one, this page shows only what that company says about itself, in its own words.

Everything said here about another company is a quote from that company’s own website, linked to the page it is on. Every quote is checked against its source daily; last confirmed . A quote that is no longer on their site is removed automatically. Product names belong to their owners, and LeadHunter USA is not affiliated with any of them.

Something here wrong or out of date? Email support@leadhunterusa.com and we will check it against your site and fix it.

Who it is for
A solo local service pro already active in local groups.

A desktop app on your own machine watches the local Facebook groups you are already a member of, and pushes a matching request to your phone. It is read-only: it never posts, comments, likes or messages, and it does not contact the lead for you.

It is built for 25 local service trades — roofers, plumbers, HVAC, electricians, handymen, tree services, cleaners, painters and more — and each trade has its own filter, so a roofer is sent roof leaks and storm damage, not every post that says "house".

When it is the wrong tool: It is the wrong tool if you want someone else to do the replying, if you want exclusive territory, or if you are not already a member of active local groups. If the computer sleeps, the watching stops until it wakes.

The two questions to ask any of these

How does it get inside the group, and whose account does it use? Does it ever post or reply for you?

Our answer: LeadHunter USA runs on your own membership, signed in as you on your own computer, and sees exactly what you would see — and nothing else. It never posts. That is a real limit as much as a feature: if you are not in the groups, there is nothing to watch. Each company’s own answer is quoted in its section above.

LeadHunter USA — $75 a month flat, every area, every lead, and we do not sell leads. Read-only: never posts, comments or messages. 7 days free, no credit card.

Common questions

What is the difference between these tools?

Mostly how each one gets into a group, and whether it posts for you. Each company’s own answer is quoted in its section on this page, with a link to where it says so. LeadHunter USA runs on your own membership, signed in as you on your own computer, and never posts, comments or messages.

Which one sees private Facebook groups?

What each company says about private groups is quoted in its section, in its own words. LeadHunter USA sees the private groups you have already joined, because it watches them signed in as you.

Will any of these get my Facebook or Nextdoor account banned?

Ask each vendor exactly how they get access before you buy. LeadHunter USA uses its own isolated session on your machine and is read-only — it never posts, comments or messages. Nothing here is a guarantee, and any vendor who gives you one is overselling.

What does LeadHunter USA cost?

LeadHunter USA costs $75 per month, flat, with no per-lead fee and no cap on how many leads are included. The annual plan is $720, which works out at $60 a month. LeadHunter USA charges the same $75 whether a contractor watches three local groups or thirty. LeadHunter USA offers a 7-day free trial and does not ask for a credit card to start it.

How does LeadHunter USA send alerts?

LeadHunter USA delivers each alert as a push notification to the contractor’s own phone, on iOS or Android, usually seconds to minutes after the post. Where each other tool sends its alerts is quoted in its section, in its own words.

How current is this page?

Everything said here about another company is a quote from its own website, checked against that page every day. A quote that is no longer on the vendor’s site is removed from this page automatically. Every quote shown was last confirmed on 2026-10-22.
