Two different building blocks: GLACIER and ATRIUM both let you build without writing code, but they solve different problems. GLACIER, part of TRIVE, is an AI vibe-coding studio: you describe what you want in plain language, and it generates a single working mini app or website, deployed directly on Web4 infrastructure. ATRIUM builds an entire social network or "super app" — messaging, content sharing and community features together — from a single AI prompt.
Scale is the key difference: Think of GLACIER as building one specific tool, and ATRIUM as building the whole platform that tool might live inside.
They're not an either/or choice: A mini app built with GLACIER can be integrated directly into a super app built with ATRIUM. A community can start with an ATRIUM network and then add its own custom, GLACIER-built tools into it as additional features, rather than being limited to what ATRIUM ships with out of the box.
Which one to start with: If you need one specific tool or internal app, start with GLACIER at glacier.linkspreed.com. If you want a whole community platform, start with ATRIUM at web4.community. If you want both, build your custom tools in GLACIER first and add them into your ATRIUM network afterwards.
