Rebuy vs Katana: at a glance
What is Rebuy?
Rebuy's feed is event recaps and ecommerce trend essays, not release notes.
The recent feed is conference recaps from the Momentum Innovation Summit in London and NYC, a BFCM infographic, and trend essays on headless commerce and AI personalization. Rebuy is a Shopify personalization and merchandising engine, but this channel carries brand and event content rather than product changes.
What is Katana?
Katana ships QuickBooks integration controls amid a feed dominated by op-eds
Katana, an MRP/inventory platform, mixes one genuine release into a feed that is otherwise how-to guides and supply-chain commentary. The lone product entry adds custom fields on sales orders and finer control over its QuickBooks integration.

Rebuy
0.0E-COMM
Rebuy's feed is event recaps and ecommerce trend essays, not release notes.
◆ Current state
The recent feed is conference recaps from the Momentum Innovation Summit in London and NYC, a BFCM infographic, and trend essays on headless commerce and AI personalization. Rebuy is a Shopify personalization and merchandising engine, but this channel carries brand and event content rather than product changes.
◆ Where it's heading
Rebuy is investing in community and thought leadership around AI merchandising and retention, the themes its events emphasize. Product direction is implied, AI-driven personalization, but not shipped in this feed.
◆ Prediction
Expect more event-driven and trend content tied to the ecommerce calendar; a dedicated release channel will be needed for actual feature news.
Katana
5.0E-COMM
Katana ships QuickBooks integration controls amid a feed dominated by op-eds
◆ Current state
Katana, an MRP/inventory platform, mixes one genuine release into a feed that is otherwise how-to guides and supply-chain commentary. The lone product entry adds custom fields on sales orders and finer control over its QuickBooks integration.
◆ Where it's heading
Product work is concentrated on multi-channel inventory accuracy (Shopify, Amazon, wholesale) and accounting sync depth. The surrounding content signals positioning around AI-era commerce and an explicit pitch against SAP closing its ERP to third-party AI.
◆ Prediction
Next moves likely continue deepening integration configurability and multi-channel sync; the SAP op-ed hints Katana wants to market itself as the AI-open alternative.
