Claw2UI - Agent-to-UI Bridge

Generate interactive web pages from TypeScript DSL specs and serve them via a public URL. Pages include Tailwind CSS, Alpine.js, and Chart.js out of the box, with pluggable themes, type checking, and mobile-responsive layouts.

Source: GitHub · npm · HF Space · License: MIT

Data Safety & User Confirmation

Every published page is accessible via a public URL. Never publish without explicit user approval.

• Always confirm with the user before publishing — describe what will be published and wait for explicit "yes"/"go ahead". Silent publishing is never acceptable
• Never include secrets, credentials, API keys, tokens, PII, or internal endpoints in page content
• Sanitize all user-provided data before embedding — the html component is sanitized server-side, but avoid passing raw untrusted input to other components
• Use TTL for ephemeral or sensitive data so pages auto-expire: --ttl 3600000 (1 hour)
• Review content before publishing — check that no sensitive information leaks through table rows, stat values, or chart labels

Setup

Claw2UI uses the public server at https://0xsegfaulted-claw2ui.hf.space by default. No local server needed.

npm install -g claw2ui
claw2ui register --server https://0xsegfaulted-claw2ui.hf.space
# Done! Token saved to ~/.claw2ui.json automatically.

Self-hosting: To run your own Claw2UI server (local, Docker, or HF Space), see the self-hosting guide.

Workflow

Step 1: Ensure Connection

# Register once (token saved to ~/.claw2ui.json)
claw2ui register --server https://0xsegfaulted-claw2ui.hf.space

Step 2: Write a TypeScript DSL Spec

Write a .ts file. Always wrap content in a container. The file is type-checked automatically.

cat > /tmp/claw2ui_page.ts << 'SPECEOF'
import { page, container, header, row, stat, card, chart, dataset } from "claw2ui/dsl"

export default page("Page Title", [
  container(
    header("Title", "Description"),
    row(3,
      stat("Metric 1", "100", { change: 5.2, icon: "trending_up" }),
      stat("Metric 2", "200"),
      stat("Metric 3", "300"),
    ),
    card("Trend",
      chart("line", {
        labels: ["Jan", "Feb", "Mar"],
        datasets: [dataset("Value", [10, 20, 15], { borderColor: "#3b82f6", tension: 0.3 })],
      }),
    ),
  ),
], { style: "anthropic" })
SPECEOF

Step 3: Confirm with User

Before publishing, tell the user what will be published and confirm they want to proceed. The page will be accessible via a public URL. Example:

"I've prepared a dashboard with [summary of content]. Ready to publish it to a public URL? (Use --ttl 3600000 for auto-expiry in 1 hour.)"

Step 4: Publish

Only after user confirmation:

claw2ui publish --spec-file /tmp/claw2ui_page.ts --title "Dashboard"
# For sensitive/temporary data, always set a TTL:
claw2ui publish --spec-file /tmp/claw2ui_page.ts --title "Dashboard" --ttl 3600000
# Skip type checking for faster publish (not recommended):
claw2ui publish --spec-file /tmp/claw2ui_page.ts --title "Dashboard" --no-check

Outputs the public URL.

Step 5: Share the URL

Include the URL in your response to the user.

Best Practices

Always use TypeScript DSL, not JSON

The DSL is type-checked, uses ~60% fewer tokens, and supports logic. JSON specs are still supported but considered legacy.

Use loops and conditionals

// Generate stats from data
const metrics = [
  { label: "CPU", value: "42%", icon: "monitor" },
  { label: "Memory", value: "6.2 GB", icon: "memory" },
  { label: "Disk", value: "120 MB/s", icon: "storage" },
]
row(3, ...metrics.map(m => stat(m.label, m.value, { icon: m.icon })))

// Conditional rendering
container(
  header("Report"),
  data.length > 0
    ? card("Trend", chart("line", chartData))
    : text("No data available"),
)

// Filter falsy values
container(
  header("Dashboard"),
  showMetrics && row(3, stat("A", "1"), stat("B", "2"), stat("C", "3")),
  card("Details", table(cols, rows)),
)

Prefer col() / badge() / dataset() helpers

// Good — concise and readable
table(
  [col("name", "Name"), col("rev", "Revenue", "currency"), badge("status", "Status", { Active: "success" })],
  rows,
)

// Avoid — verbose raw objects
table(
  [{ key: "name", label: "Name" }, { key: "rev", label: "Revenue", format: "currency" }, { key: "status", label: "Status", format: "badge", badgeMap: { Active: "success" } }],
  rows,
)

Use markdown() for rich text

card("About",
  markdown(`
## Features
- **Fast** — sub-second rendering
- **Secure** — sanitized HTML output
- **Responsive** — mobile-first layouts

> Built with Claw2UI
  `),
)

Use months() for chart labels

chart("bar", {
  labels: months(6),
  datasets: [dataset("Revenue", [100, 200, 150, 300, 250, 400])],
})

Design Patterns

Dashboard

import { page, container, header, row, stat, card, chart, table, col, badge, dataset } from "claw2ui/dsl"

export default page("Dashboard", [
  container(
    header("Dashboard", "Overview"),
    row(3,
      stat("Revenue", "$1.2M", { change: 15.3, icon: "payments" }),
      stat("Orders", "8,432", { change: 8.1, icon: "shopping_cart" }),
      stat("Customers", "2,847", { change: -2.5, icon: "group" }),
    ),
    card("Trend",
      chart("line", {
        labels: months(6),
        datasets: [dataset("Revenue", [320, 410, 380, 450, 480, 520], {
          borderColor: "#3b82f6", tension: 0.3, fill: true,
          backgroundColor: "rgba(59,130,246,0.1)",
        })],
      }, { height: 280 }),
    ),
    card("Details",
      table(
        [col("name", "Name"), col("value", "Value", "currency"), badge("status", "Status", { Active: "success", Inactive: "error" })],
        [
          { name: "Product A", value: 450000, status: "Active" },
          { name: "Product B", value: 320000, status: "Active" },
          { name: "Product C", value: 0, status: "Inactive" },
        ],
      ),
    ),
  ),
], { style: "anthropic" })

Report with Tabs

import { page, container, header, row, stat, card, chart, table, tabs, tab, text, markdown, col, dataset, months } from "claw2ui/dsl"

export default page("Monthly Report", [
  container(
    header("Monthly Report", "March 2026"),
    tabs(
      tab("overview", "Overview",
        row(3,
          stat("Users", "12,847", { change: 18.5, icon: "group" }),
          stat("Revenue", "$89K", { change: 24.3, icon: "payments" }),
          stat("Churn", "3.2%", { change: -1.1, icon: "trending_down" }),
        ),
        card("Growth",
          chart("line", {
            labels: months(6),
            datasets: [
              dataset("Users", [8000, 9200, 10100, 11000, 11800, 12847], { borderColor: "#3b82f6" }),
              dataset("Revenue", [52, 58, 65, 72, 81, 89], { borderColor: "#10b981", yAxisID: "y1" }),
            ],
          }),
        ),
      ),
      tab("details", "Details",
        table(
          [col("page", "Page"), col("views", "Views"), col("bounce", "Bounce", "percent")],
          [
            { page: "/", views: "23,456", bounce: 28 },
            { page: "/pricing", views: "12,567", bounce: 22 },
            { page: "/docs", views: "9,876", bounce: 18 },
          ],
        ),
      ),
      tab("notes", "Notes",
        markdown("## Key Takeaways\
\
- Revenue up **24.3%** MoM\
- Churn improved by 1.1pp\
- `/pricing` page has lowest bounce rate"),
      ),
    ),
  ),
], { style: "anthropic" })

Comparison

import { page, container, header, row, card, stat, text, table, col } from "claw2ui/dsl"

export default page("Plan Comparison", [
  container(
    header("Plan Comparison", "Choose the right plan"),
    row(3,
      card("Starter",
        stat("Price", "$9/mo"),
        text("5 users, 10 GB storage"),
      ),
      card("Pro",
        stat("Price", "$29/mo", { icon: "star" }),
        text("25 users, 100 GB storage"),
      ),
      card("Enterprise",
        stat("Price", "Custom", { icon: "business" }),
        text("Unlimited users, 1 TB storage"),
      ),
    ),
    card("Feature Matrix",
      table(
        [col("feature", "Feature"), col("starter", "Starter"), col("pro", "Pro"), col("enterprise", "Enterprise")],
        [
          { feature: "Users", starter: "5", pro: "25", enterprise: "Unlimited" },
          { feature: "Storage", starter: "10 GB", pro: "100 GB", enterprise: "1 TB" },
          { feature: "Support", starter: "Email", pro: "Priority", enterprise: "Dedicated" },
        ],
      ),
    ),
  ),
], { style: "anthropic" })
