As someone with experience writing Django backed websites and various scripts and applications for my work, I can say coding is a near thankless job.

Warframe.market is a website you can use for free, someone coded it and poured their heart and soul into it and not only that, someone is paying for hosting.

Don't be that horrible person who focuses on the negative.. New release has issues, give it time and when it's stable be constructive.

The fastest way to get a site shutdown is be overly harsh on a product you are not entitled to.

I'm not in any way affiliated with warframe.market but it's clearly a work of love.

EDIT: grammar and typos from phone.

Additional: sure there's clearly some income from ads and patreon - I'd say most people have adblock so no dice there (a lot of sites using ads for revenue are facing the same problem). Patreon - so people found value in the site and contributed but a highly trafficked site isn't free - it's not your $99 dedicated server that you run your pet projects on.

Also - nowhere did I say the site should be free from criticism, just don't be a toxic basement reject and act entitled. If you do that, there might not be a site to criticise anymore. If you feel that strongly about a community project, kick off your own. I'm certainly capable but you know, I'd rather be playing Warframe than contributing commits to something people are just going to rag on.
