I think this is ultimately caused by a Bun bug which I reported, which means source maps are exposed in production: https://github.com/oven-sh/bun/issues/28001

I think this is ultimately caused by a Bun bug which I reported, which means source maps are exposed in production: https://github.com/oven-sh/bun/issues/28001 https://github.com/oven-sh/bun/issues/28001 Claude code uses (and Anthropic owns) Bun, so my guess is they're doing a production build, expecting it not to output source maps, but it is.

Open Claude Code? Better than OpenCode and Codex
- rurban 6mo ago
  Not really. This guy expresses my feelings: https://www.youtube.com/watch?v=nxB4M3GlcWQ https://www.youtube.com/watch?v=nxB4M3GlcWQ I also prefer codex over claude. But opencode is best. If you can use a good model. We can via Github Business Subscription.
  - sandipb 6mo ago
    The only issue I have with opencode is that it takes over the entire terminal, unlike claude code. Otherwise I love OC.
- arcanemachiner 6mo ago
  I wish. Claude Code is clearly a pile of vibe-coded garbage. The UI is janky and jumps all over the place, especially during longer sessions. (Which also have a several second delay to render. In a terminal). Lately, it's been crashing if I hold the Backspace key down for too long. Being open-source would be the best thing to happen to them. At least they would finally get a pair of human eyes looking at their codebase. Claude is amazing, but the people at Anthropic make some insane decisions, including trying (and failing, apparently) to keep Claude Code a closed-source application.

    As a point of reference, I’m a heavy cc user and I’ve had a few bugs but I’ve never had the terminal glitches like this. I use iterm on macOS sequoia.
    - breatheoften 6mo ago
      To offer the opposite anecdotal evidence point -- claude scrolls to the top of the chat history almost capriciously often (more often than not) for me using iterm on tahoe
      - JelteF 6mo ago
        Scrolling around when claude is "typing" makes it jump to the top
      - jen20 6mo ago
        I've had it do it occasionally in all of Ghostty, iTerm2 and Prompt 3 (via SSH, not sure what terminal emulator that uses under the hood)

        I thought I was the only one who had this problem - so annoying, and the frequent Ui glitches when it asks you to choose an option .
      - iterateoften 6mo ago
        Wow I thought it was tmux messing up on me, interesting to hear it happens without it too
        rafaelmn 6mo ago
        Not tmux related at all had it happen in all kinds of setups (alacritty/linux, vscode terminal macos)
    - jetbalsa 6mo ago
      i will note that they really should of used something like ncurses and kept the animations down, TTYs are NOT meant to do the level of crazy modern TUIs are trying to pull off, there is just too many terminal emulators out there that just don't like the weird control codes being sent around.
- lrvick 6mo ago
  If you want something better than both of those try Crush which is a standalone go binary by the original developer of OpenCode.

It could be because of a Bun bug, but I don't think it's because of that one. It's a duplicate of a year-old issue, and it's specific to Bun.serve.
- petcat 6mo ago
  Yeah this bun development server bug has nothing to do with the Claude Code leak.
cute_boi 6mo ago
I don’t think that’s the reason, but using Bun for production this early is a bad idea. It’s still too buggy, and compromising stability for a 2–3% performance gain just isn’t worth it.
- leeoniya 6mo ago
  > for a 2–3% performance gain this is highly workload-dependent. there are plenty of APIs that are multiple-factor faster and 10x more memory efficient due to native implementation.
dimgl 6mo ago
I doubt it's this. This was an `npm` misconfiguration.
chalmovsky 6mo ago
It was not cause by this. https://github.com/oven-sh/bun/issues/28001#issuecomment-4164447815 https://github.com/oven-sh/bun/issues/28001#issuecomment-416...

Were source maps needed? Reverse engineering got easy with GPT-4.2-Codex and Opus 4.6 - even from raw binaries https://quesma.com/blog/chromatron-recompiled/ https://quesma.com/blog/chromatron-recompiled/
jakegmaths 6mo ago
My apologies, this isn't the cause. Bun build doesn't suffer from this bug.
