• User experience/ease of use (grade 1 to 10, lets take Proton as a benchmark with an 8): 6
• Pricing: Based on solidarity, but recommend minimum is 5 € per month

https://www.hostsharing.net/

• Server location (jurisdiction): Germany
• Integrity/trustworthiness/transparency: well, you own part of hostsharing if you use it (collective-ownership)
