HeyGen CLI

What it does

Your agent can now generate video, translate content, create avatars, and deliver, straight from the terminal. Every command returns structured JSON and works out of the box in scripts, CI pipelines, and agent workflows.

Official HeyGen API documentation. Build AI avatar videos, translations, and interactive sessions. Start free, scale on pay-as-you-go from $5.

We orchestrate avatars, voices, images, editing, music, and assets into deterministic, repeatable renders, and deliver production-ready video into your own stack. From one video to batches of thousands on HeyGen Cloud. Onboarding walkthroughs, partner training, guided support — if your team repeats it by hand today, it can run as a persistent, programmable presence. Describe the work and the assistant maps it to the endpoints that automate it — before you write a line of code. “We can update their lines as needed, without ever having to return to the studio.” Miro’s product-education videos star digital twins of their real presenters — when the product changes, the same trusted faces…from developers.heygen.com

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
