Castport on Web Browser
Runs in any modern browser — nothing to install, works the same on any machine you log in from.
Setup on Web Browser
Download the installer
Download the latest Castport installer from the GitHub Releases page (https://github.com/bensblueprints/castport-mvp/releases) — or build it yourself from the MIT source.
Install
Run the installer — one click, no terminal, no account to create.
Run it locally
Castport runs 100% on your machine — no account, no telemetry, and it keeps working with the Wi-Fi off.
What works offline: everything. Castport is a desktop app — once it's installed, no feature needs a connection to us.
Castport on Web Browser — honest answers
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/castport-mvp, always. $99 buys the packaged installer, guided deploy and lifetime updates.
Will Apple and Spotify actually accept the feed?
That's the part we sweated: exact enclosure byte counts (not estimates), permanent GUIDs, real probed audio durations, and proper HTTP Range support on audio — the exact details that get naive feeds rejected. Set BASE_URL to your real domain first; localhost feeds are rejected.
