In this talk, the speaker will explore how Astro Content Collections create a true abstraction layer, letting developers swap CMSs without touching component code. Through live demos migrating between four different headless CMSs, attendees will see this pattern in action. Maciek will also mention all the limitations. ## Speaker ### [Maciek Palmowski](https://www.wearedevelopers.com/@maciek-palmowski) Security Community Manager at Patchstack ## Related talks at this congress - [Frontend Abstractions: Frameworks and Applications Architectural Patterns](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1549-frontend) — Abdu Taviq - [Designing for Every Direction: Logical CSS for Global, Adaptive, and Effortlessly Reversible UIs](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1525-designing-for-every) — Vidhya Krishnamoorthy - [The Async Revolution: Balancing Focus, Alignment, and Agility](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1615-the-async-revolution) — Gabriel Casals - [Why Is Software Documentation Still Static – And Why Modern Browsers Deserve Better](https://www.wearedevelopers.com/events/world-congress-2026-europe-virtual-stage/sessions/1644-why-is-software) — André Dietrich, Jihad Hyadi
