Akismet Alternatives Compared: Free, $12 and CAPTCHA

The free Akismet alternative most sites should install is Antispam Bee: free forever for commercial projects as well as personal ones, 700,000+ active installs, rated 4.8 out of 5 from 226 reviews, and it reaches its verdict on your own server instead of posting every comment to a third party. If the spam is arriving through registrations, contact forms or a WooCommerce checkout, Antispam Bee will not see it and Anti-Spam by CleanTalk will, at $12 a year for one site against the $119.40 a year Akismet charges for the cheapest plan a commercial site is permitted to buy. If you want the bill at zero and will accept a challenge on the form, Cloudflare Turnstile is free with unlimited challenges — but a challenge is a toll on every visitor, not a filter on every submission.

Where exactly does Akismet stop being free?

Akismet Personal is name your price, with unlimited spam checks on unlimited sites. It is also, in Akismet’s own words, “for personal sites”. Before you can take it you confirm three statements: I don’t have ads on my site, I don’t sell products/services on my site, and I don’t promote a business on my site. The page then says plainly that if your site does not meet those qualifications you must choose a commercial plan.

Most people read that as “no shop, no ads” and assume a modest blog is safe. Akismet’s own support documentation is more specific, and this is the list that catches people out. A free Personal key does not cover:

• Ad code of any kind, naming Google AdSense, Taboola, Infolinks and ExoClick.
• Affiliate links.
• Promoting a business or service.
• Running on e-commerce plugins or platforms.
• Accepting donations, or running a donation plugin.
• A domain recognised as commercial.
• Live chat plugins or services.

Akismet states that free keys “do not support commercial activities” and that noncompliance “will result in immediate suspension of services without notice”. A hobby blog with one affiliate link, a tip jar or a support-chat bubble is on the wrong plan by that reading, which is why so many people arrive at this search without ever having opened a shop.

The commercial ladder starts at Pro, $9.95 a month billed yearly: one site, 500 spam checks a month. It steps up to two sites and 1,000 checks at $19.90, three and 1,500 at $29.85, and four and 2,000 at $39.80. Above that sits Business at $49.95 a month billed yearly, which covers unlimited sites but caps the whole account at 5,000 checks a month, then Enterprise at a price on application. Registered nonprofits get a free key capped at 60,000 API calls a month.

Two things about that ceiling matter. A check is any submission Akismet inspects, legitimate or not, so a busy contact form eats the allowance as fast as a spam run does. And 500 checks a month is under 17 a day, which a single lightly-used contact form can exceed before a single comment arrives.

What does leaving Akismet actually save?

Here is the same site priced across every option on this page, at one site and at ten, with each plan’s monthly ceiling converted into a per-day number so the limit means something. All arithmetic is on a 30-day month.

Prices read from each vendor’s own pricing page on 12 September 2026. Annual figures are the advertised monthly price multiplied by twelve.

The number worth taking away is in the last column, and it does not move. Akismet Pro at $119.40 a year gives one site under 17 checks a day. Pro at its top tier, $477.60 a year, gives each of four sites under 17 checks a day. Business, at $599.40 a year and five times the entry price, spread over ten sites gives each of them under 17 checks a day. Every Akismet plan buys the same per-site headroom; what the extra money buys is more sites, not more room on the site you already have. So if the reason you are here is that you ran out of checks, moving up an Akismet tier will not fix it. Every alternative in the table has no ceiling at all, and the cheapest of them costs $12 a year.

Which Akismet alternative fits your reason for leaving?

People leave Akismet for four different reasons, and the four reasons have different answers. Set yours below and the pick changes.

Every branch uses the figures in the table above, read from WordPress.org and each vendor’s pricing page on 12 September 2026.

The Akismet alternatives compared

Versions, installs, ratings and review counts read from each plugin’s WordPress.org page on 12 September 2026; prices from each vendor’s pricing page the same day. All seven plugins are tested to WordPress 7.1.

CleanTalk vs Akismet

These two work the same way, which makes the comparison unusually clean. Both are cloud filters: the submission goes to a remote service, the service returns a verdict, and neither asks your visitor to do anything. If you were content with how Akismet behaved and only object to the bill or the ceiling, CleanTalk is the like-for-like swap.

Price. CleanTalk is $12 a year for one site with unlimited spam checks. The cheapest plan Akismet permits a commercial site is $119.40 a year for 500 checks a month. That is 9.95 times the price for a metered service instead of an unmetered one. At ten sites it is $69 against $599.40.

Scope. Akismet filters comments and contact forms. CleanTalk also covers user registrations, WooCommerce orders, bookings, newsletter signups and custom forms, across 70+ form plugins, from one settings page. That breadth is the real reason to move rather than the price.

Where Akismet wins. Reach and inertia. Akismet has 5 million+ active installs against CleanTalk’s 200,000+, it ships with WordPress, and a site that already has a working key needs no decision at all. CleanTalk carries a higher rating on far more feedback — 4.8 from 3,211 reviews against 4.7 from 1,186 — but it is a subscription, and when it lapses the filtering stops, because the verdicts were never on your server.

WPNeon runs Anti-Spam by CleanTalk 6.87 on this site and does not run Akismet. The detail, including what to do about false positives, is in the CleanTalk review. CleanTalk pricing and trial (Affiliate link) · the plugin on WordPress.org

Antispam Bee vs Akismet

This is the comparison behind “akismet alternative free”, and the answer turns on two differences that have nothing to do with how well either one catches spam.

The licence. Antispam Bee’s listing says it is “free forever, for both private and commercial projects”, on as many sites as you like, with no plan above it. Akismet’s free tier excludes ads, affiliate links, e-commerce, donations, live chat and a domain recognised as commercial. For the large middle group — a blog with one affiliate link or a tip jar — that single difference decides it.

Where the comment goes. Akismet posts the comment, the author name, the email address and the IP to Automattic for a verdict, which makes it a third-party processor you must name in your privacy policy. Antispam Bee reaches its decision in PHP on your own server, so there is no processor to declare and no ceiling to run out of.

Where Akismet wins. Scope and scale. Antispam Bee protects comments and trackbacks, full stop; if your spam arrives through a contact form or a registration page it will never see it. Akismet also covers contact forms and has 5 million+ installs to Antispam Bee’s 700,000+. On rating the gap runs the other way: 4.8 from 226 reviews against 4.7 from 1,186.

reCAPTCHA or Turnstile vs Akismet

This one deserves a straight answer: a CAPTCHA is not a spam filter, and it is not really an Akismet alternative. Akismet inspects the submission after it is sent and decides silently. A CAPTCHA makes every visitor prove something before they can send anything. One is a filter on submissions, the other is a tax on visitors, and they fail in opposite directions. A CAPTCHA stops bots that cannot solve it and does nothing whatever about spam typed by a paid human, which is most of what gets through on a site worth targeting.

Where a challenge earns its place is when a cloud filter is not an option — a policy that forbids sending submissions to a filtering service, or a budget of exactly zero on a site with forms. On price the three differ sharply:

• Cloudflare Turnstile is free with unlimited challenges, up to 20 widgets and 10 hostnames per widget, and your domain does not need to use Cloudflare DNS.
• hCaptcha has a free Basic plan; Pro is $99 a month billed annually, or $139 billed monthly, for 100,000 evaluations and $0.99 per 1,000 after that.
• Google reCAPTCHA Essentials is free to 10,000 assessments a month, but that allowance is per organisation and aggregates across every account and every site you run. Premium charges a flat $8.00 from 10,001 to 100,000 assessments, then $1.00 per 1,000.

Turnstile is the one to take if you want a challenge, because it is the only one of the three with no volume cliff. Do not run a challenge and a cloud filter together on the same form: you pay the conversion cost of the challenge and gain nothing the filter was not already doing.

The alternatives in detail

Antispam Bee

For a blog whose only problem is the comment box, and whose only objection to Akismet is the licence or the bill. Version 2.11.13, updated in August 2026, 700,000+ active installs, 4.8 out of 5 from 226 reviews, tested to WordPress 7.1, requires PHP 5.2.

The capability that decides it is the licence combined with the architecture: free for commercial projects with no plan above it, unlimited sites, and every verdict reached on your own server. That answers both reasons people leave Akismet in a single install, and there is nothing metered to run out of.

The limitation is scope, and it is absolute. Comments and trackbacks are all it touches. Registration spam, contact-form spam and WooCommerce order spam pass it without being looked at.

Anti-Spam by CleanTalk

For sites where spam arrives through more than one door. Plugin version 6.87, updated in September 2026, 200,000+ active installs, 4.8 out of 5 from 3,211 reviews — the largest review count on this page — tested to WordPress 7.1, requires PHP 7.2.

Breadth is the capability. Comments, registrations, contact forms, WooCommerce orders, bookings and newsletter signups are covered from one screen, across 70+ form plugins, using behavioural analysis, invisible JavaScript tests and a shared spam database rather than a challenge. Spam checks are unlimited on every package, which is the direct answer to Akismet’s 500-a-month entry ceiling.

The limitation is that there is no permanent free tier and no local fallback: the service decides, so cover ends when the subscription does. It is $12 a year for one site, $36 for five, $69 for ten and $27 a month for unlimited sites.

WP Armour – Honeypot Anti Spam

For sites that must not send submissions anywhere, but need more than comments protected. Version 2.4.02, updated in September 2026, 400,000+ active installs, rated 5 out of 5 from 1,440 reviews, tested to WordPress 7.1.

The deciding capability is stated flatly on its listing: “No external API calls like Akismet or CleanTalk for spam filtering”, with no tracking, no cookie storage and no external server calls. It injects a honeypot field with JavaScript, which bots fill and humans never see, and the free build covers WordPress comments and registration, bbPress, Contact Form 7, Gravity Forms, WPForms, Formidable, Elementor Forms, Fluent Forms and WooCommerce reviews.

The limitation is the paywall line. WooCommerce checkout and registration, Easy Digital Downloads, Ninja Forms, MC4WP and BuddyPress are in the paid Extended version, so a shop does not get full cover for free. A honeypot also does nothing against a human filling the form by hand.

Cloudflare Turnstile

For a zero budget on a site with forms, where a visible challenge is acceptable. The Simple Cloudflare Turnstile plugin is version 1.43.0, updated in September 2026, 200,000+ active installs, 4.7 out of 5 from 256 reviews, tested to WordPress 7.1, with no premium version.

What decides it against the other challenges is that the free plan has no volume cliff: unlimited challenges, up to 20 widgets, 10 hostnames per widget, and no requirement to move your DNS to Cloudflare. The plugin covers the comment form, login, registration, password reset, WooCommerce checkout and account pages, and nine form builders including WPForms, Contact Form 7 and Gravity Forms.

The limitation is what a challenge is. It costs every real visitor a moment and some proportion of them the submission, and it will not stop a human being paid to post links.

hCaptcha for WP

For a site that wants a challenge from neither Cloudflare nor Google. Version 5.3.0, updated in September 2026, 70,000+ active installs, 4.6 out of 5 from 86 reviews, tested to WordPress 7.1, requires PHP 7.4.

Its useful capability is reach: 60+ integrations covering logins, registrations, lost-password forms, comments, checkout and custom forms, plus honeypot fields, IP access control and country blocking in the plugin itself. hCaptcha’s Basic plan costs nothing.

The limitation is the upgrade path. Low-friction passive mode, custom themes and analytics are on Pro at $99 a month billed annually, which is a large step from free, and with 86 reviews it has the thinnest feedback of anything on this page.

Titan Anti-spam & Security

For a site being hit at the login page as well as the comment box. Version 7.5.2, updated in August 2026, 50,000+ active installs, 4.5 out of 5 from 370 reviews, tested to WordPress 7.1, requires PHP 7.4.

The reason to pick it is that it treats comment spam and brute-force login attempts as one problem, which they usually are, since the same networks drive both. The free version blocks comment spam without a CAPTCHA, limits login attempts, and hardens the install by hiding the WordPress version and disabling XML-RPC.

The limitation is where the good filtering sits. Machine-learning spam detection, rescanning comments you already have, spam-account detection and two-factor authentication are all in Pro, and 4.5 is the lowest rating among the plugins kept here.

The route that needs no plugin at all

Before installing anything, check whether you already own the fix. Two places usually have it.

WordPress Settings, Discussion. Core ships four controls that remove most comment spam without a filter: Automatically close comments on articles older than [X] days, which kills spam on old posts where almost all of it lands; Comment author must have a previously approved comment; Hold a comment in the queue if it contains [X] or more links; and the Comment Blocklist, which marks as spam any comment matching a word, name, URL, email, IP or user-agent you list. Closing comments after 30 days is the single highest-value setting on that screen for an archive-heavy blog.

Your form plugin’s own honeypot. If the spam is coming through a form, the form plugin may already stop it. Gravity Forms, for one, has an Anti-spam honeypot checkbox under Form Options in Form Settings, described by its maker as a built-in feature available free with all licence types. Turning on a switch you already paid for beats adding a seventh plugin.

Neither route covers registration or checkout spam, and neither reads content the way a filter does. They are the first thing to try, not the last.

Which “Akismet alternatives” to ignore

Older lists still recommend plugins that are no longer safe to install. Three names come up repeatedly.

WPBruiser, listed as goodbye-captcha, was closed on WordPress.org on 23 July 2026 pending a full review and cannot be downloaded. Its last release predates WordPress 5.6, and it is tested only to WordPress 5.5.20. If it is on your site, deactivate and delete it.

WP-SpamShield was closed on 28 October 2017 for a guideline violation, and that closure is permanent. It is tested to WordPress 4.8.30.

Stop Spammers is still downloadable at version 2026.6, with 30,000+ installs and 4.4 from 243 reviews, but its own author states that development has ended and it receives security patches only. Tested to WordPress 7.0.4. It is not dangerous, but it is not a plugin to start with.

Which Akismet alternative should you choose?

For most people, Antispam Bee. It is free for commercial sites as well as personal ones, it keeps comment data on your own server, it has no check ceiling to hit, and at 700,000+ installs and 4.8 from 226 reviews it is thoroughly proven. Install it, deactivate Akismet, and read your moderation queue for a fortnight before deleting anything.

If the spam is not in the comment box, CleanTalk at $12 a year. Registrations, contact forms, bookings and WooCommerce orders are outside Antispam Bee’s reach entirely, and CleanTalk covers all of them with unlimited checks for a tenth of what Akismet charges a commercial site.

If nothing may leave your server, WP Armour. Its honeypot makes no external calls at all, which neither Akismet, CleanTalk nor any CAPTCHA can claim — but price the paid Extended version first if the WooCommerce checkout is the target.

Skip the CAPTCHA route unless you have to use it. Turnstile is free and unlimited and the best of the three, but every challenge is paid for by real visitors, and none of them stops a human writing spam by hand. Whichever you take, run one anti-spam tool, not three. Stacked filters fight each other and make it impossible to tell which one ate a legitimate comment.

Once you have chosen

• The wider anti-spam plugin field — if you are not leaving Akismet specifically and want the full comparison rather than the switch.
• CleanTalk review — the setup, the dashboard and the false-positive question, before you spend the $12.
• WordPress comment plugins — if the comment section itself is the problem and moving off the native form is on the table.
• WordPress security plugins — for the login and brute-force half of the same bot traffic, where doubling up causes the same trouble it does here.

Frequently asked questions

Is there a free version of Akismet?

Yes, but only for non-commercial sites. Akismet Personal is name your price with unlimited checks, and taking it means confirming you have no ads, do not sell products or services, and do not promote a business. Akismet also excludes affiliate links, donation plugins, e-commerce platforms and live chat from free keys, and says non-compliance results in immediate suspension without notice.

What is the best free Akismet alternative?

Antispam Bee, for a site whose spam arrives in the comment box. It is free for commercial projects as well as personal ones, runs on unlimited sites, has no paid tier and no check ceiling, and decides on your own server rather than sending comments to a third party. It has 700,000+ active installs and is rated 4.8 out of 5 from 226 reviews.

Is CleanTalk better than Akismet?

For scope and price, yes. CleanTalk covers registrations, contact forms, WooCommerce orders and bookings as well as comments, with unlimited spam checks, for $12 a year against $119.40 for the cheapest Akismet plan a commercial site may buy. Akismet is larger, at 5 million-plus installs against 200,000-plus, and ships with WordPress. Both are cloud services, so neither keeps submissions on your server.

Is Antispam Bee enough on its own?

It is enough if comments and trackbacks are the whole problem, and not otherwise. Antispam Bee does not inspect user registrations, contact form submissions or WooCommerce orders, so a membership site or a shop needs something broader such as CleanTalk, or a honeypot plugin such as WP Armour if nothing may leave the server.

Can reCAPTCHA replace Akismet?

Not really, because they do different jobs. Akismet filters a submission after it is sent; reCAPTCHA asks every visitor to prove something before they can send it. A challenge stops bots and does nothing about spam typed by a human. If you want one anyway, Cloudflare Turnstile is free with unlimited challenges, while reCAPTCHA Essentials is free only to 10,000 assessments a month across your whole organisation.

Should I keep Akismet installed as well?

No. Two filters on the same comment form duplicate the work and make it impossible to tell which one blocked a legitimate comment, and Akismet keeps counting checks against your plan while it runs. Deactivate and delete it once the replacement has run cleanly for a fortnight, and empty the spam queue before you remove anything.
