• There is a list of dapps/sites on HIVE.IO (the official portal to the blockchain):
https://hive.io/eco
• Many dapps/sites are listed on HiveProjects.io:
https://hiveprojects.io
NOTE: Not all devs have listed their projects there, so the above lists aren't complete, sadly.
• I have compiled a list of front-ends to Hive, and try to update it when I find others:

• I have compiled a list of some of the most-used dapps/sites on Hive:

Hopefully, these will help your project! 🙂
