# CartStack > CartStack is revenue recovery software for ecommerce stores, hotels and > ticketed attractions. It identifies visitors who leave without buying and > brings them back through email, SMS and push — and catches some of them > before they leave at all. Three products, sold together or separately. Recover works after someone leaves, Retain works while they are still on the page, and Reveal identifies the anonymous visitors neither of the other two can reach. ## Products - [Recover](https://www.cartstack.com/products/recover): Abandoned cart and booking recovery. The moment a visitor leaves — a product page, a room search, a half-finished checkout — Recover follows up by email, SMS and push until they come back or the sequence ends. - [Retain](https://www.cartstack.com/products/retain): On-site retention. Exit-intent offers, on-site nudges, cart reminders and tab alerts that stop the abandonment before it happens, including for visitors who have not identified themselves. - [Reveal](https://www.cartstack.com/products/reveal): Visitor identification. Most visitors never say who they are; Reveal identifies high-intent anonymous traffic on your own site and turns it into contacts you can act on. ## Solutions - [Ecommerce](https://www.cartstack.com/solutions/ecommerce): Recovering abandoned carts and browsing sessions for online stores. - [Hospitality](https://www.cartstack.com/solutions/hospitality): Booking abandonment recovery for hotels, resorts and vacation rentals, aimed at direct bookings rather than OTA channels. Formerly sold as RezRecover. - [Ticketing](https://www.cartstack.com/solutions/ticketing): Recovering abandoned ticket and admission orders for venues, attractions and events. ## Integrations - [Integrations](https://www.cartstack.com/integrations): CartStack installs with one script tag and has documented setups for over a hundred ecommerce platforms, booking engines, ticketing systems and technology partners. It runs on any platform that accepts a script tag. ## Writing - [Blog](https://www.cartstack.com/blog): Abandoned cart recovery tactics, benchmarks and the occasional opinion for stores, properties and box offices. ## Optional - [Sitemap](https://www.cartstack.com/sitemap.xml): Every indexable URL on the site, regenerated on each deploy.
