www.Peakd.com is (probably together with Ecency) the frontend of Hive with the most features and capabilities.
It originated from https://steempeak.com/ on the Steem blockchain, but after the fork to Hive it closed its operations on Steem to fully focus on developing the frontend for Hive|Reference: @steempeak (2020) SteemPeak goes Quietly into the Sunset https://steemit.com/hive-175001/@steempeak/steempeak-goes-quietly-into-the-sunset.
It was founded by @jarvie and @asgarth.
Noteworthy on Peakd are the "Badges", up to 8 icons in a users profile page indicating special features or community memberships.
Another unique feature are the "Collections", lists of posts a user can create which collect e.g. special subtopics or themes, "best of" lists, etc. of his own posts or across many other users.
If a user prefers microblogging, with posting just short texts like in X (former Twitter) and those posts not publishing as main posts on the Hive blockchain but as comments rather, he/she may check out Ecency or InLeo, which both have a microblogging feature.
