Roadmap

The current stage of Proto UI and the main direction of its evolution from v0 to v1

Proto UI is currently in its v0 stage.

At this stage, the priority is not to expand surface-level features as quickly as possible. Instead, the focus is on completing the foundational protocol loop first: making sure the core information pathways, execution semantics, and cross-host translation model have a stable and verifiable basis.

v0 is the stage where Proto UI moves from concept to verifiable implementation.

At this stage, Proto UI is mainly focused on the following goals:

• consolidating the foundational model for expressing component prototypes
• stabilizing the core semantics shared by prototypes, adapters, and runtimes
• using contract tests to verify consistency across different implementations
• validating how Prototypes can be realized across multiple host environments
• establishing a dependable reference baseline for the foundational prototype library and the adapter ecosystem

The significance of v0 is not that it delivers a fully complete UI framework. Its role is to confirm that the Proto UI protocol model can work, can be implemented in practice, and can serve as a foundation for further expansion.

In v1, Proto UI will move beyond being merely verifiable as a protocol and toward becoming stable and dependable in practice.

Compared with v0, v1 will focus on:

• providing clear stability and backward-compatibility guarantees for prototype syntax
• developing the Compiler into a more primary execution path
• extending Proto UI beyond Web targets to a broader range of platforms
• continuing to build out the official prototype library, adapters, and related tooling
• forming a more complete relationship between protocol semantics, generation capabilities, and ecosystem collaboration

If v0 mainly answers the question “Can Proto UI work as a model?”, then v1 is more concerned with “How can Proto UI scale into broader practice in a stable way?”

At the v0 stage, Proto UI does not yet promise the following:

• industrial-grade backward compatibility guarantees
• comprehensive performance optimization
• a mature and complete adapter ecosystem
• stable implementations across all target platforms

These capabilities are important, but they depend on the protocol semantics being sufficiently stabilized and the foundational constraints being clearly established first.

Proto UI does not evolve by piling up features first and cleaning up the foundation later.

Instead, it first clarifies the semantics of the protocol layer, the relationships between adapters and hosts, and the boundaries of implementation. Only then does it gradually expand its stability guarantees, generation capabilities, and ecosystem scale.

v0 focuses on whether this model can work and be implemented in practice.
v1 focuses on how this model can scale in a stable way and remain viable over time.
