What It Is

BoostN Dev is more of a small plugin store and support forum for the XenForo 2 ecosystem than a general-purpose developer platform. The site shows only one main category, Product Support, and two products: SendySync and Slack Notify. Purchases and downloads require users to be XenForo Licensed Customers and to pass the site’s license verification.

Core Features and Ecosystem

SendySync 2.3.5 is the main paid product. It is designed to keep Sendy.co mailing lists in sync with XenForo user lists, supporting synchronization from Sendy user lists to XF User and automatically handling bounces and complaints. Its description specifically emphasizes using Sendy as the “Source of Truth,” which suggests it is better suited to forum sites that treat their email subscription system as the primary data source. Slack Notify 2.1.1, meanwhile, is an admin tool that sends notifications such as error reports and user registration alerts to Slack channels. The supported framework is clearly XenForo 2, but the site does not disclose details about the underlying language, whether the code is open, or any API/SDK information.

Pricing and Licensing

Pricing is relatively clear: SendySync costs $20, with a 12-month license term and a $10 renewal fee; Slack Notify is free, also with a 12-month license term and a $0 renewal fee. Because XenForo license verification is required before downloading, it is not suitable for users who do not have a legitimate XenForo license.

Pros and Cons

The strengths are its clearly defined use cases and modest pricing. SendySync still has release records in 2026, indicating that at least this product is still being maintained. The drawbacks are also obvious: the forum is very small, with only 34 members, 10 threads, and 23 messages shown on the page. Public pages lack detailed installation documentation, compatibility notes, troubleshooting guidance, and a support SLA. Slack Notify’s most recent publicly visible update was in 2019, so its maintenance activity is questionable.

Who It’s For and Access from China

It is suitable for forum owners and technical administrators running XenForo 2 who also use Sendy.co or Slack. It is not a good fit for teams that need a large ecosystem, comprehensive documentation, or enterprise-grade support. Access from China and supported payment methods are not stated in the available content, so their status should be considered unknown. If Sendy or Slack are affected by network conditions in actual use, you may want to consider alternative plugins from the official XenForo resource marketplace, or build your own integration using the Sendy API and Slack Webhook.
