Which should you pick?
Pick EchoThread if you want a permanent free tier instead of a 30-day trial, simple flat pricing, and a first-party ML classifier tuned for AI-generated spam. Pick FastComments if you want the deepest community feature set — SSO, real-time chat, surveys, localization in 14+ languages, and dozens of platform integrations — and a standing free plan is not a dealbreaker.
Where FastComments is the better call
FastComments is a mature, ad-free platform with the broadest feature set in this comparison: single sign-on and webhooks, real-time live chat and direct messages, ratings and surveys, localization in 14+ languages, server-side rendering, and dozens of platform integrations with official framework SDKs. If you want the deepest community toolkit available today and do not need a permanent free tier, FastComments is an excellent, well-established choice.
The difference that matters in 2026
Built for AI-generated comment spam.
Comment spam is now AI-generated — fluent, on-topic, and invisible to keyword filters and Akismet bolt-ons. EchoThread ships a first-party ML classifier (Siftfy) that scores every comment the moment it lands, so you can let readers comment freely and still keep threads clean.
Create your free siteQuestions
- Is EchoThread cheaper than FastComments?
- EchoThread has a permanently free Hobby tier (10,000 page views and 1,000 comments per month, per site). FastComments runs a 30-day trial and then bills on every plan — its usage-based Flex plan starts under $1/month but there is no standing free tier. EchoThread paid plans start at $5/month for 3 sites and 100,000 page views.
- Do EchoThread and FastComments both avoid ads and tracking?
- Yes. Both are ad-free and avoid third-party tracking cookies, which is the main reason people leave Disqus for either one. The deciding factors are usually pricing, spam handling, and how much community tooling you need.
- How is EchoThread's spam filtering different from FastComments'?
- Both filter spam automatically — this is not a case where one tool leaves you exposed. FastComments uses a Bayesian classifier with an LLM second pass. EchoThread uses a first-party machine-learning classifier (Siftfy) built specifically to catch fluent, AI-generated comment spam the moment it is posted.
