* feat(cli): smart port selection with instance reuse Replace the simple 10-port retry loop with best-in-class port handling: - Multi-host port testing (127.0.0.1, 0.0.0.0, ::1, ::) catches ports occupied by SSH forwarding or other interfaces invisible to localhost - HTTP probe (/__hyperframes_config) detects existing HyperFrames preview servers — reuses same-project instances instead of spawning duplicates, skips different-project instances - PID detection via lsof for actionable "Port N in use by PID X" logs - Expanded scan range from 10 to 100 ports - Added --force-new flag to bypass instance detection - Async PID detection (execFile, no shell) and parallel host testing Fixes the "10 ports are all in use" error that occurs when zombie preview servers accumulate or devbox port forwarding occupies ports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(cli): add --list and --kill-all flags to preview command - `hyperframes preview --list` scans the port range and displays all active HyperFrames preview servers with their project name, directory, and PID - `hyperframes preview --kill-all` kills all active preview servers - Port scanning uses parallel batched probes (20 at a time) for speed Gives users visibility into zombie preview servers and a one-command way to clean them up.

hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4:
npx hyperframes render ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
