🔍 Buyer's guide

CommentGuard alternatives, compared honestly

We make one of these, so read this knowing that. What follows is the option set we can actually vouch for — including Meta's own free tools, which are the right answer for more people than any vendor will tell you — and the questions that decide between them.

The six questions Just the head-to-head →

The options

Four options, and where our facts come from

There are other tools in this category. They are not listed here because we cannot source them, and a comparison built on a competitor's marketing claims is worth less than no comparison at all. CommentGuard's details are from their help centre and pricing page, checked 26 October 2026, and a hands-on trial account on 15 August 2026. NapoleonCat's are limited to what its public pricing page states — prices, plan limits, platforms — checked 26 October 2026. We have not trialled it, so nothing here says how well it works.

Meta's built-in moderation Free

Best for: One quiet Page, run by the person who owns it.

What it does well: It is already there, it costs nothing, and for a Page that gets a handful of comments a week it is genuinely enough. Keyword blocklist, a profanity toggle, hide or delete by hand.

Where it runs out: The blocklist catches common misspellings of the words you add, but not meaning, so a scam in fresh wording is a new entry you have to think of first. It is per Page, access is granted Page by Page in Meta’s own settings with no view across Pages, and there is no record of what was hidden or why.

CommentGuard From $29/mo

Best for: Teams who want AI filters and comment-to-reply automation today.

What it does well: The incumbent, and ahead of us on AI filters and automations: a keyword or emoji triggers a public reply from a rotating set, with an optional delay. Also further along on bulk inbox actions and muting an author, and it offers annual billing.

Where it runs out: OpenAI-only with no model choice, a 7-day trial, and their help centre confirms no public API, no Zapier, no comment assignment, no AI-to-human handover and no bot detection.

NapoleonCat $139/mo to auto-hide

Best for: Teams moderating more than Facebook and Instagram from one inbox.

What it does well: The widest platform list here: TikTok, YouTube, LinkedIn, X and Google Business reviews sit in the same inbox as Facebook and Instagram, and auto-moderation covers Facebook, Instagram and TikTok ad comments. It is a full social suite, so scheduling, analytics and reporting come with it. 14-day trial, no card.

Where it runs out: Automatic hiding starts on the Expert plan: $139/mo, or $119/mo billed yearly, for 2 users and 5 profile slots, and adding either raises the price. AI spam and hate-speech detection is a separate $29/mo add-on. If Facebook and Instagram moderation is all you need, most of that price pays for the suite around it.

CommentDefender From $9/mo

Best for: Facebook and Instagram comment moderation without a suite around it, starting small.

What it does well: Every Page, seat and filter on every plan, a label on each hidden comment naming the rule that hid it, and per-Page team access so nobody shares a password. 14-day trial, no card, and 1,000 comments for $9 at the bottom of the ladder.

Where it runs out: The AI stage is switched off right now, so the profanity and negativity filters and the Claude-drafted replies are configurable but not acting. Also no keyword-triggered reply automations, no white-label, no reseller invoicing and no public API.

However you decide

Six questions to ask any of them

These separate the tools in this category far better than a feature grid does, and they work just as well on a vendor we have never heard of.

1

Can it moderate the surfaces you actually post on?

Instagram Stories, live video and Advantage+ catalogue ads cannot be moderated by anyone — those are limits in Meta's API. A tool implying otherwise is describing something it cannot do.

2

Are rules per Page, or one setting for everything?

A restaurant and a political campaign do not share a definition of "negativity". If you run more than one client, ask how a rule set moves between Pages, and whether copying replaces or merges.

3

How do other people get access?

The honest answer for a lot of setups is "share the client's password". Ask for roles and per-Page scoping instead, and check what the lowest role can actually change.

4

What exactly counts toward the quota?

Comments received, or actions taken? Do replies count? Ours counts every comment that arrives once, hidden or not. Whatever the answer, get it before the first invoice rather than after.

5

What happens when you hit the limit?

Moderation stopping is defensible. Silently continuing and billing you for it is not. Ask which one it does, and whether it warns you first — ours does not warn yet, and says so.

6

Which model writes the AI replies, and can you see the prompt?

AI reply quality is the thing you will actually live with. Ask what model, whether you can ground it in your own content, and whether replies are reviewed before sending or sent unattended.

True of every option here

Three things none of them do

✓ Clean up your back catalogue. Moderation starts when you connect. No tool working within Meta's API reprocesses your history.
✓ Moderate Stories, live video or Advantage+ catalogue ads. Meta does not expose them for it.
✓ Hide the Page owner's own comments. A comment from the account that owns the post stays visible even when hidden.

If the answer turns out to be us

14 days, no card. Connect one Page and see what the first day catches — that settles it faster than any comparison page, ours included.
