What Crucible does

A fast, native Plex client with Skip Intro, Picture-in-Picture, lock-screen controls, and Handoff — open source, zero dependencies, and built entirely on Arch Linux without ever opening Xcode.

A player that respects your time

Skip Intro and Skip Credits from Plex markers, Picture-in-Picture, background audio, and lock-screen controls. Credits roll the next episode automatically.

Plays anything

Direct play when your device handles the file natively, automatic HLS transcoding through Plex's universal transcoder when it doesn't.

Browse the way you think

Continue Watching, On Deck, and Recently Added up front. Poster grids with genre filters and sort, plus raw folder browsing for unindexed content.

Discover more

Cast and crew, More Like This recommendations, subtitle and audio track selection, and adjustable playback speed on every title.

Continues across devices

Watch progress syncs to your server, resume picks up where you left off, and Handoff plus Spotlight carry titles between your devices.

Built different

Swift 6 and programmatic UIKit with Liquid Glass on iOS 26, cross-compiled on Arch Linux and deployed over USB. No Xcode, no macOS, no dependencies.

About Crucible

Crucible is a fast, native Plex client for iPhone — and a love letter to building iOS apps without a Mac. The whole app is Swift 6 and programmatic UIKit, cross-compiled on Arch Linux and deployed straight to an iPhone over USB. No Xcode, no storyboards, no macOS anywhere in the loop.

EVERYTHING IN ITS PLACE

Continue Watching, On Deck, and Recently Added greet you on the home screen. Browse libraries as poster grids with genre filters and sort options, or dig into raw folders for unindexed content.

A PLAYER THAT RESPECTS YOUR TIME

Skip Intro and Skip Credits straight from Plex markers, Picture-in-Picture with background audio, lock screen and Control Center controls, and Up Next that rolls the next episode as the credits start. Direct play when your device can handle the file, automatic HLS transcoding when it can't.

GO DEEPER

Cast and crew, More Like This recommendations, subtitle and audio track selection, and adjustable playback speed. Hand a title off between your devices and find what you've watched in Spotlight.

OPEN SOURCE, BUILT ON LINUX

Crucible is free and open source under the GPL-3.0 license, with zero third-party dependencies — pure Apple frameworks. Read the code, file an issue, or build it yourself.

./crucible --faq

Frequently asked questions

Is Crucible on the App Store?

No. Crucible is a free, open-source personal project — not an App Store release. You build it from source and deploy it to your own iPhone with xtool, or grab a tagged release from GitHub.

Do I need a Mac or Xcode to build it?

No. That's the whole point. Crucible is written in Swift 6 and programmatic UIKit, cross-compiled on Arch Linux with SwiftPM, and deployed to an iPhone over USB via xtool. No Xcode, no storyboards, no macOS anywhere.

What does it need to run?

An iPhone on iOS 17 or later and a Plex Media Server you can reach. Crucible talks directly to your server — it works great over Tailscale for secure remote access.

Does it support Skip Intro, PiP, and lock-screen controls?

Yes. Skip Intro and Skip Credits come from Plex chapter markers, Picture-in-Picture and background audio keep playback going, and the lock screen and Control Center drive play, skip, scrub, and next episode.

Is it really open source?

Yes — GPL-3.0, with zero third-party dependencies (pure Apple frameworks). Read the code, file an issue, or fork it on GitHub.
