What It Is

Fast Feedback is a comments and reviews tool for static websites, positioning itself as “the easiest way to add comments or reviews to static sites.” Based on the available content, it generates an embed URL from a site ID, and developers can enable the feedback module by placing an iframe on the page. Comments must be approved before they are displayed, which suggests it includes at least a basic moderation workflow.

Core Features and Integration

Its primary integration method is <iframe src="https://fastfeedback.io/embed/SITE_ID" />, making it very friendly for static sites that do not want to maintain a backend. It also supports multiple routes: by appending a unique ROUTE slug to the embed URL, different blog posts or product pages under the same site can have separate comment sections. For iframe height adjustment, the documentation recommends using iframe-resizer and provides an example with iframe-resizer-react in React. If developers want full control over the visual style, they can also call /api/feedback/SITE_ID to fetch feedback data; the main content includes a React + SWR example for reading it.

Pricing and Openness

The page has a Pricing entry, but the scraped content does not provide specific prices, free quotas, or plan differences, so it is not possible to assess the long-term cost. The content also does not state whether the project is open source or self-hostable. The API only shows basic GET usage for reading feedback, with no disclosure of authentication, writing, pagination, deletion, export, anti-spam, or related capabilities.

Pros and Cons

Its main advantage is the very low barrier to entry: iframe embedding is suitable for static blogs, documentation sites, and product landing pages. Multi-route support allows it to cover two common scenarios: blog comments and product reviews. The API also supports some degree of custom display. The downside is that the public documentation is rather brief, with insufficient information on commercialization, data control, the moderation dashboard, spam handling, and SLA. Teams should verify these points further before adopting it in production.

Who It’s For and Access from China

It is suitable for frontend developers and static site maintainers who want to quickly add a comment section without building a comment system themselves. If full self-hosting or an open-source ecosystem is important to you, consider comparing it with alternatives such as Giscus, Utterances, Cusdis, and Commento. The content does not describe access conditions from mainland China, so it is recommended to test the reachability of fastfeedback.io and the embedded iframe before actual use. Payment methods are also not disclosed.
