Withdrawn from the index
Stacker is no longer in the App Builder Index
Status today: Now an AI agent platform, not an app builder.
Stacker has changed category. The site now leads with AI agents that get work done, described as more than just a chatbot. The builder we reviewed has gone with it: there are no pages to design, no schema designer and no deploy step. We removed Stacker from the App Builder Index on 20 August 2026, when we re-verified every tool against its own live pages. Anyone who came here looking for the customer portal builder should read that as the answer: the product they remember is not what the vendor sells today.
