Walkcast questions. Every answer in one place.

What is Walkcast?

Walkcast is a free, open-source Windows app that makes a narrated video walkthrough from a website link. A real browser signs in, visits up to 30 pages on that site, and returns an MP4 with a spoken voice-over, WebVTT captions and a transcript. Every line of narration comes from what the browser actually did.

Which computers does Walkcast run on?

The desktop app installs on Windows 10 or 11, 64-bit. On macOS and Linux you can run it from source with Node.js 22, Rust and ffmpeg.

How do I make a narrated video walkthrough of my website?

Install Walkcast, paste the site's link, add the username and password you normally sign in with, confirm you may test the site, and press Record. You get an MP4 with a spoken voice-over, a WebVTT caption file and a transcript.

Can it record pages behind a login?

Yes. It finds the sign-in form, including two-step email-then-password forms, signs in with the credentials you give it, and then records the pages you only see when signed in.

Is my password stored?

No. It is held in memory for the recording only. Traces, captions and files on disk show a placeholder, and the narration never reads it out.

Will it change anything on my site?

After signing in it only follows links on the same site with ordinary page loads. It submits no forms, skips sign-out, delete, cancel and unsubscribe links, and respects robots.txt.

What happens with CAPTCHAs or two-factor?

The recorder stops and tells you. It never tries to get past a CAPTCHA, bot check or second-factor prompt.

Does the narration make things up?

No. Every line is written from what the browser actually did: which page it opened, which field it typed into, what it clicked and what the site answered.

Is Walkcast free?

Yes. It is MIT licensed with no paid tier, seat limit or usage meter, and it runs on your own PC.

What files does a recording produce?

An MP4 (H.264 video, AAC narration and an embedded caption track), a WebM copy with the narration, the narration as a WAV file, WebVTT captions, and a list of every page visited with its HTTP status.

How long does a recording take?

Usually a minute or two. A six-page site records, narrates and encodes in under a minute on an ordinary laptop; it scales with the number of pages, up to 30.

Which voices does it use?

On Windows the narration is spoken by the voices built into Windows (a female or a male voice). When run from source on Linux or macOS it uses ffmpeg's flite voices. Nothing is sent to a speech service unless you configure one.

Can I edit the narration?

Yes. In the app's Studio you can rewrite any line of the script and re-narrate the video, or replace the voice with your own recording.

Does Walkcast upload my recordings?

No. Recordings are written to the app's folder on your PC and are not uploaded anywhere. You share the MP4 yourself.

Can it record internal tools or a local development site?

Yes. Because it runs on your PC, it can record any site that PC can reach, including localhost and company intranets, as long as you may test it.
