Stackable Labs is agnoStack's developer platform for building on-brand interactive experiences inside Zendesk Messenger.
Launched on May 14, 2026, Stackable Labs is an AI-powered open developer platform enabling brands to build interactive experiences atop Zendesk Messenger. Stackable wraps Zendesk Messenger with real functionality — instant answers on messenger open, and self-service actions such as order tracking, purchase history, subscription skip/cadence change, CSAT surveys and engagement opt-ins rendered inside the conversation, branded with the customer's colors, logo and layout.
The platform includes the Stackable Marketplace of ready-made extensions, Stackable AI Studio (describe an extension in plain language and it builds it), Shelf ready-made components, and a full SDK with docs at developers.stackablelabs.com, with hosting, security and auth handled at the platform level.
