[0.1.0] — 2026-04-21

Public launch. First stable release.

Added

• Single-file Swift CLI wrapping WKWebView for AI agent workflows
• Three modes of operation:
  • --url <url> to open any URL (http/https/file/agent)
  • --a2ui to read A2UI v0.8 JSONL from stdin and render with the built-in renderer
  • Stdin load command for piping custom HTML resources via agent:// scheme
• A2UI renderer supporting 9 components: Text, TextInput, Button, Column, Row, Card, Select, Checkbox, Divider
• Stdout JSON protocol: {"status":"completed","data":{...}} / cancelled / timeout / error
• Exit codes: 0 completed, 1 cancelled, 2 timeout, 3 error
• WKScriptMessageHandler bridge for complete and ready events
• applicationWillTerminate safety net: emits cancelled on SIGTERM
• Escape key and Cmd+W both emit cancelled
• Homebrew tap at giannimassi/homebrew-tap
• /webview skill for Claude Code agents with templates for approval, select, form, and confirmation patterns

Performance

• 193KB binary (no runtime dependencies beyond macOS system frameworks)
• ~180ms cold-start on Apple Silicon (spawn → page rendered)
• macOS 12+ (Swift runtime ships with OS, no bundled libswiftCore)

Known limitations

• macOS-only — no Linux or Windows port
• A2UI subset only — no Image, List, RadioGroup components yet
• No data-binding expressions (dataModelUpdate not fully supported)
• No --css custom-theme flag (opinionated defaults only)
• No persistent cookie storage across invocations (WKWebsiteDataStore.default() is ephemeral)
• No code signing or notarization — Gatekeeper will warn on first open unless installed via brew
