Argo (@argo-video/cli)

Argo is a command-line tool by shreyaskarnik that turns Playwright demo scripts into product demo videos with AI voiceover. The user writes a Playwright script and a scenes manifest in JSON, then runs one command to get an MP4 with overlays and narration. Kokoro (local, no API key) or OpenAI (cloud, needs an API key) generates the voice clips. Playwright records the browser and marks scene timestamps, the clips are aligned to those marks, and ffmpeg merges video and audio. Config options include 1920x1080 at 30 fps capture, a cursor highlight and an SVG pointer, scene transitions, speed ramps, and GIF or 9:16 exports. The repo is MIT-licensed with 149 stars, created on 2026-03-13. The latest release is v0.42.1 (2026-10-27).
