Single Grain keeps publishing AI-for-marketing how-tos, not product changes
A side-by-side editorial comparison of Swipe Pages and Umbraco CMS — release velocity, themes, recent moves, and the top alternatives to consider.
A landing page builder that turned itself into an agent surface, then started charging for it.
Swipe Pages has spent 2026 converting a conventional landing page builder into an agent-driven one. The AI Agents launch in December 2025 established chat-based page generation; every release since has hardened it — Code Mode with model selection and block locking, AI image generation in-builder, tracking codes and Events API integrations carried over from the classic product. As of July, AI pages have reached feature parity with the hand-built ones on the things that matter commercially: A/B testing, personalization, and cross-subaccount portability.
Umbraco 19 reaches its first release candidate on .NET 11 GA.
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.
Swipe Pages has spent 2026 converting a conventional landing page builder into an agent-driven one. The AI Agents launch in December 2025 established chat-based page generation; every release since has hardened it — Code Mode with model selection and block locking, AI image generation in-builder, tracking codes and Events API integrations carried over from the classic product. As of July, AI pages have reached feature parity with the hand-built ones on the things that matter commercially: A/B testing, personalization, and cross-subaccount portability.
Two arcs are converging. The first is distribution: Swipe Genie became addressable from outside the product via MCP in April, first on request, then GA across all plans in July — the builder is now something an external agent drives, not just a UI a marketer opens. The second is monetization: AI credits landed on every plan in May as a purchasable, non-expiring unit, which turns generation volume into revenue rather than cost. Bug-fix releases in between are dominated by agent-session plumbing — transcripts, thought signatures, invitee access — the maintenance profile of a product whose core loop is now a conversation.
Expect the credit system to gain the usual second-order machinery — per-subaccount allocation and usage reporting — since subaccount timezone and analytics work is already landing. The MCP surface reaching GA on all plans without a matching pricing line suggests agent-driven publishing is next to be metered.
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.
The 19 cycle is moving quickly from beta to candidate, and rc1 is about hardening rather than new editor features: dependencies on GA, environment-level permissions and load-balancing performance. The 17 and 18 lines are kept in step on security fixes while 19 matures.
Expect 18.3 and 17.8 to go stable, followed by further 19 release candidates and a 19.0.0 stable release built on .NET 11.
