Why Crawlbench never touches your Facebook account

Why does Crawlbench never touch your Facebook account?

Because your Facebook account is how you buy, and losing it would cost more than any single deal. We made two decisions early, and they hold on every plan:

1. No Facebook login. You sign in to Crawlbench with Google, Apple or your email. We never ask for your Facebook password, a Facebook session or permission to act on your Facebook account.
2. No messages to sellers. Crawlbench finds the listing, checks its price against similar listings and alerts you. Every message to a seller comes from you, from your own account.

A tool you can cancel tomorrow should not be able to put that account at risk today.

Does a Marketplace tool need your Facebook login?

Only if it acts through your account or runs on your computer with it. A Facebook Marketplace tool relates to your account in one of three ways, sometimes two at once, and its own site usually tells you which.

1. Watches without it. The tool checks Marketplace on its own servers. It never sees your login, and nothing it does happens on your account.
2. Acts through it. The tool, or an AI agent, sends messages or offers from your account. Every message carries your name. Facebook publishes no limit for how much automated messaging is too much, so nobody can tell you where the line is.
3. Runs on your machine with it. A browser extension or desktop app checks Marketplace from your computer while you are signed in, so its searches come from your account, and it stops when the computer sleeps. Some of these also send messages, which makes them both kinds at once (extension or hosted, compared).

What do other tools and Muse's terms say?

Here is what five tools and Meta's Muse say about your account, on their own sites. Each line names the page and the day we read it, and reports what the company says, not a verdict on whether it follows Facebook's rules.

Watches without it:

• Outpost Alerts says it searches Facebook Marketplace from its own servers, so it never asks for your Facebook login, and you message sellers in Facebook as usual (home page, read 20 Oct 2026).
• SuperFlip AI says it never requires your Facebook login or credentials, and scans publicly available listings without connecting to your Facebook account (home page, read 20 Oct 2026).
• Flipify says core alerts work without linking an account and it never asks for marketplace passwords; its optional Facebook auto-messaging needs you to sign in to Facebook, and keeps that session on your device (home page, read 20 Oct 2026). Its alerts watch without your account; its optional messaging acts through it.

Lists outreach, without saying how:

• Swoopa lists AI-assisted outreach among its plan features, and the page does not say how those messages reach sellers or whether they go out from your Facebook account (pricing page, read 20 Oct 2026). Ask Swoopa how it works before you turn it on.

Runs on your machine and acts through it:

• Pounce says it is a Windows app that needs a Facebook account that can access Marketplace; with Auto-message on, it sends an opener from the account that found the listing; its FAQ says any Marketplace automation has risk, and suggests aged secondary or backup accounts and not pushing too hard on your main one (home page, read 20 Oct 2026).

An AI agent that acts for you:

Muse is Meta's AI agent. Muse's terms, as they read when this post was published, say:

• It uses AI and the services you connect to "serve as your AI agent and take actions on your behalf".
• You alone are responsible for what it does in your name.
• You should review state-changing actions, such as sending messages, before they happen, or approve them in advance.
• Meta may suspend your access to Muse and to associated Meta accounts if it finds a violation or a risk. Your Facebook account is a Meta account.

What do you give up with a tool that never touches your account?

You give up anything that needs your account to act, and that is a real cost. Three things change:

• No first message while you sleep. An auto-messenger can write to a seller before you see the alert. With Crawlbench, the first message waits for you.
• No automatic offers or haggling. You write every offer and every reply.
• Only what Facebook shows publicly. Crawlbench checks Facebook Marketplace signed out, on our own servers. It sees the listings Facebook shows anyone who isn't signed in, and it uses no Facebook account, yours or ours. A listing Facebook shows only to signed-in people is outside what we check.

What you keep is an account that only does what you do.

What does Crawlbench do instead?

Crawlbench does the part of the job that doesn't need your account, in every city your search covers, with no tab left open.

• Searches you write once: what you buy, a price cap, words to leave out and the cities you'll drive to.
• Checks on our servers: Busy cities are checked every minute on Scale, every 2 minutes on Pro, every 5 on Growth and every 10 on Starter. Each plan's speed is on Pricing.
• A price check on every alert: each listing next to the usual price of similar listings, with the range and how many listings it rests on.
• Alerts where you already look: email, Telegram, Slack, Discord or the Phone app, on every plan. The API and webhooks are on the plans listed on Pricing (every alert channel).
• The Team desk on team plans: every new listing once for the whole team, claimed by one person, so two people never message the same seller.

About Crawlbench lists what it does today, with the countries and cities it covers and the day they were measured.

What should you ask any tool before you connect your account?

Ask five questions, and read the answer on the tool's own site, not in an ad:

1. Does it ask for my Facebook login, a session or a connection to my account? If yes, it acts through your account or runs with it.
2. Where does it run? On its own servers, or on my computer and in my browser? If it is on your machine, it searches as you.
3. Can anything go out in my name? Messages, offers or listings. Is that off until I turn it on, and can I read each message before it is sent?
4. What does its own site say about account risk? A tool that suggests spare or secondary accounts is telling you how it sees the risk.
5. What stays connected if I cancel? Nothing should. Sign out of any session it used.
