Akismet Review
Last updated: 2026-08-07
Overview
Akismet is a spam filtering service created by Automattic in 2005, originally built for WordPress.com and now used on millions of sites. It checks comments, trackbacks, and contact form submissions against a global spam database using machine learning to identify malicious content. The service processes hundreds of millions of spam checks daily. Rated 4.5/5 on SaaSFilter, Akismet is the default spam solution in WordPress — it ships pre-installed on every new WordPress site and requires only an API key to activate.
Pros & Cons
Pros
- Zero-touch integration — install and it starts filtering automatically
- Real-time spam detection reduces manual moderation dramatically
- Spam statistics dashboard shows what was caught
- Wide compatibility with comment systems and contact form plugins
- Free for personal, non-commercial sites
Cons
- Commercial sites must pay — free tier is personal use only
- Can occasionally false-positive legitimate comments
- Requires an API key from Automattic (small setup step)
- No custom moderation rules — it's all-or-nothing filtering
Features
Akismet automatically checks each comment and pingback against its cloud-based spam database, flagging suspicious content before it reaches your moderation queue. The status history shows which comments were caught and why, with one-click "not spam" corrections that improve the global filter. The moderation screen displays a spam count and lets you review caught items in bulk. Akismet integrates with contact form plugins including Contact Form 7, Gravity Forms, and WPForms — form submissions pass through the same spam check. The API is available for non-WordPress applications via REST endpoints, accepting text, author name, email, and URL for scoring. Account-level stats show total spam caught, accuracy rate, and monthly volume. Limitations: Akismet doesn't handle bot traffic (that's a CDN/WAF job), the comment review interface is minimal, false positives require manual unflagging, and there's no granular rule customization — you're trusting the algorithm entirely. The API rate limits aren't documented clearly for custom integrations.

Pricing
Akismet Personal is free for personal sites and blogs with no ads — includes spam filtering for unlimited comments. Akismet Plus at $9.95/month covers commercial sites and adds priority support. Akismet Enterprise at $49.95/month includes multiple sites, higher API limits, and SLA-backed support. Akismet Elite at $249/month handles high-volume networks and agency deployments. All plans include automatic spam catching, moderation history, and the API. No free trial needed — the Personal plan is permanently free for non-commercial use. Annual billing is available but doesn't offer a discount over monthly pricing.
Final Verdict
4.5/5. Akismet is best for any WordPress site that accepts comments or contact form submissions — it catches 95%+ of spam with zero configuration. The free Personal plan is genuinely free for non-commercial use. Drawbacks: no customization of filtering rules, occasional false positives that need manual correction, and it doesn't address bot protection or rate limiting. For comment and form spam specifically, Akismet remains the WordPress standard.
Frequently Asked Questions
Is Akismet worth it in 2026?
Yes for virtually any WordPress site with comments or contact forms. Akismet catches spam automatically with minimal false positives, and the Personal plan is free for non-commercial sites. The only reason to skip it is if you've disabled comments entirely and use a form plugin with built-in spam protection like hCaptcha.
How much does Akismet cost?
Personal: free for non-commercial sites. Plus: $9.95/month for commercial sites. Enterprise: $49.95/month for multiple sites with higher API limits. Elite: $249/month for high-volume networks. All plans include the same core spam filtering — paid tiers add support and capacity.
What are the best Akismet alternatives?
hCaptcha and Cloudflare Turnstile handle bot protection that Akismet doesn't. Anti-Spam Bee is a free WordPress plugin with local spam detection. Spam Protection by CleanTalk offers similar filtering with different pricing. For form spam specifically, hCaptcha on Contact Form 7 works well.
Does Akismet offer a free trial or free plan?
Yes — Akismet Personal is permanently free for personal, non-commercial sites with no ads. It includes full spam filtering for unlimited comments. Commercial sites need a paid plan starting at $9.95/month. No credit card required for the Personal plan.
