Spectra
Spectra spins up a standalone Gutenberg block plugin — with a paid tier from day one.
A side-by-side editorial comparison of shadcn/ui and Greenshift — release velocity, themes, recent moves, and the top alternatives to consider.
shadcn is becoming a base-agnostic distribution layer, not just a component library.
shadcn/ui has decoupled itself from any single primitive library: Base UI is now the default for new projects, Radix is still supported, and React Aria has been added as a third selectable base. In parallel, the registry has opened up—any public GitHub repository can now act as a shadcn registry, with tooling to organize and validate sources. The component surface is expanding toward AI app building, with a chat-interface set and AI SDK helpers landing alongside a new typography system.
Greenshift's arc: from a Gutenberg block pack to a full builder, now spun out white-label.
Greenshift is a Gutenberg-native block and page-builder plugin. The visible entries span 2023 to 2025 and show it maturing from a block collection into a full builder (class system, StyleBook, variable builder, interaction APIs) while branching into WooCommerce commerce blocks and, most recently, a white-label standalone (GreenLight). The feed mixes real release notes with the occasional editorial post.

The through-line is distribution: shadcn is turning 'copy the code you own' into an ecosystem where primitive bases are swappable and registries are decentralized. The AI-adjacent additions—chat components plus AI SDK and TanStack AI helpers—point at positioning the library as the default UI layer for LLM apps. Ownership stays the core bet: eject inlines everything and removes the dependency entirely.
Expect the base-agnostic story to continue—likely more primitive bases and finer per-component base selection—alongside deeper AI-app scaffolding built on the new chat and helper primitives.

The direction is twofold: deepen the builder (filter blocks, animation chains, Anchor and Scroll APIs) and widen distribution by packaging the block set for agencies to resell under their own brand. The editorial defense of Gutenberg signals a firm bet on the native block editor over third-party builders.
GreenLight suggests the next moves center on the agency and white-label market plus continued builder parity. Note the newest entry is July 2025, so this feed is roughly a year stale and likely misses more recent releases.
