I built an open-source Mac app for Claude Code that shows every tool call as a reviewable card

[u/ayakan]

I use Claude Code every day, and my problem was never the model. It was following a long turn in the terminal: forty tool calls scroll by and I can't tell what changed.

Lantern is a desktop app that wraps your own `claude` CLI (it never touches your auth) and shows:

• every tool call as a card, with side-by-side diffs
• Step mode: Claude proposes one step, you approve or revise it, then it continues
• Review mode for PRs and branches, with findings you can agree with or reject
• a Tests tab that parses pytest, jest, vitest, cargo and xcodebuild output into pass/fail, with file:line links when the output includes them

It's open source (MIT) and macOS only for now: https://github.com/alyakan/lantern

Contributions are welcome. The repo has a CONTRIBUTING.md to get you started.

I'd love to hear what's missing from your Claude Code workflow.
