Show HN: UnUI – Help coding agents make better design decisions

UnUI, a new tool from an independent developer, helps coding agents make better design decisions by turning real interface examples into compact, agent-readable design context. The tool extracts layout hierarchy, spacing, color, and component habits from reference pages, producing an Evidence Pack that agents can cite during implementation. UnUI avoids generic handoffs and preset component systems, keeping agent decisions close to the project's existing codebase.

No finished pages to buy, paste, or force into the current project.

Design evidence

Real samples become layout hierarchy, spacing rhythm, color tone, and reusable interface patterns.

Turns “make it look like this” into references agents can cite.

Design context for coding agents

Turn real interface examples into compact design evidence agents can use inside your project.

unUI skips generic handoffs and turns real interface patterns into agent-readable design context.

No finished pages to buy, paste, or force into the current project.

Real samples become layout hierarchy, spacing rhythm, color tone, and reusable interface patterns.

Turns “make it look like this” into references agents can cite.

No preset component system, and no new UI stack for the project to obey.

Codebase tokens, component habits, naming, and constraints are organized before implementation.

Keeps agent decisions close to the files already being edited.

No static screenshots or mockups that leave implementation choices for later.

Component composition, responsive behavior, and style boundaries are compressed for the current agent task.

Puts visual judgment into CLI-readable context so agents can execute it.

Controlled comparison

unUI keeps every page grounded in a consistent, restrained design language—so attention stays on what matters, not arbitrary visual invention.

Shared task

Track quarterly team goals, overall progress, product owners, and nested key results from one view.

Shared task

Manage verified and pending domains, SSL state, DNS records, and verification actions in one focused panel.

Shared task

Monitor Ethereum mempool health, fee pressure, and newly observed pending transactions.

Shared task

Monitor monthly request quota, daily volume, endpoint consumption, and utilization from one dashboard.

Shared task

Present product releases with clear version and date hierarchy, concise narratives, and scannable change details.

Workflow

When adding a page, unUI first turns evidence from similar interfaces into compact context, then hands it to your local agent to implement inside the current project.

unUI extracts structure, spacing, color, and component habits from real pages and open-source UI fragments.

Your agent reads the Evidence Pack and turns style evidence into an implementation inside your project.
