"Threadloom Newsletter has been very rewarding. Increased activity on the forum and interaction between forum members. Worth every penny IMHO!"

Dave Blears, owner

"We are convinced. After much testing (easy with side-by-side test mode), we've found the search results returned by Threadloom to be superior to our elasticsearch results."

Frequently-asked questions

How is Threadloom Search different from XenForo Enhanced Search or Sphinx?

Threadloom is the only search engine for forums securely hosted in the cloud. This lets you offload intensive search queries, and gives you access to advanced features like image search, spell correction, and blog search. There is nothing for you to manage, aside from periodic plug-in upgrades.

How long does it take to get started with Threadloom?

Most forums launch Threadloom Search or Newsletter with less than 15 minutes of active time. There is a waiting period while we build your index. We email you when it's complete so you can finish your configuration on the Threadloom Portal.

Do you sell or share my data?

We do not sell or share your data with any third parties, except for data processing as required to support our services, e.g., Microsoft Azure for spell correction. We are Privacy Shield-certified. You can read more about our commitment to privacy and security in our privacy policy.

What if I decide to cancel?

All plans are month-to-month. You can cancel your subscription in the Threadloom Portal or by dropping us a line.
