Kaku v0.5 is now available. A fast macOS terminal with great defaults, built for AI coding. Zero config. Codename Yohaku🪽.
github.com/tw93/Kaku
If you live in the terminal all day, this release is for you. I tried to make the common loop faster: run commands, fix errors…Show more, navigate files, review diffs, repeat.
Highlights
• AI Shell fixes: when a command fails, Kaku sends it to the AI and shows the fix in-terminal. Press Cmd Shift E to apply
• Built-in yazi: Cmd Shift Y or type y. First run auto-sets layout and theme. cd Tab falls back to z history when filesystem has no match
• Shell line editing like a real editor: Cmd A select all, Shift arrows extend selection, type to replace selection
• Command palette: Cmd Shift P to fuzzy search commands, with native text editing
• One place for AI configs: kaku ai manages Kaku Assistant, Factory Droid, and opencode.jsonc
• Kaku Doctor: run kaku doctor to detect config issues and fix them interactively
• Global hotkey: Ctrl Opt Cmd K to show or hide Kaku from any app
• Tab bell indicator: background tabs show a blinking dot when something finishes or notifies
• Scrolling and input polish: smoother trackpad scrolling in less and man, better fallback scroll mode, improved CJK IME popup positioning
• Performance: faster startup via Lua bytecode cache and lazy loading, smaller binary via build optimizations
• Shell integration detection fixed: works across environments without relying on TERM being kaku
What do you want from a great engineer terminal in 2026. Anything you miss in your current setup, tell me and I will try to build it.
Saw a very cool tool on GitHub called PortKiller. It’s a powerful cross-platform port management app for developers, with a native UI on macOS, Windows, and Linux.
What makes it fun is that it goes beyond just listing ports. It auto-discovers all listening TCP ports…Show more, lets you kill processes with one click, supports search and filtering, favorites, watched ports with notifications, and smart categorization for common dev services.
It also covers real workflows: managing kubectl port-forward sessions with auto-reconnect, logs, and connect or disconnect notifications, plus visibility into active Cloudflare Tunnel connections.
> brew install –cask productdevbook/tap/portkiller.
Claude just launched a program for open-source maintainers, offering 6 months of free Claude Max 20x.
I’ve applied.
If you’re a primary maintainer of a public repo with 5K+ stars, or a core contributor to a package with 1M+ monthly npm downloads…Show more, and have been active in the last 3 months, you should take a look.
If you’ve been actively contributing to larger OSS projects, including Mole, Pake, MiaoYan or others, and meet the criteria, this might be relevant to you.
Support for serious open-source work matters.
I recently came across a very cool tool called Surge. It’s a blazing-fast, open-source TUI download manager built in Go for power users, with a clean keyboard-driven workflow.
What makes it fun is that it doesn’t treat downloads as a single stream. Surge opens multiple…Show more connections, splits the file into chunks, and pulls them down in parallel, while also supporting multiple mirrors with automatic failover. It even has a streaming mode if you want sequential downloading for previewing media.
It runs as a background engine so you can queue downloads from any terminal tab, and the TUI looks great while staying lightweight and focused.
> brew install surge-downloader/tap/surge
Discovered SuperCmd on GitHub, an open source launcher for macOS. More complete than I expected.
It brings Raycast style extension workflows, voice input, text to speech, memory, and AI actions into one open system.
Exciting to see this level of open source innovation in the macOS launcher space. Worth exploring.
github.com/SuperCmdLabs/SuperCmd
I just integrated yazi into Kaku. Yazi is a terminal file manager written in Rust, built on non-blocking async I O. It is fast, smooth, and surprisingly fun to use.
In the next Kaku release…Show more, yazi will be built in with my tuned config and defaults. I spent a bunch of time polishing the keybindings and the overall feel, and it now fits Kaku really well.
If you want it right now, you can install it first, Then run yazi
> brew install yazi
0:09Kaku is about to ship a feature that makes command line input feel like a real text editor. github.com/tw93/Kaku
Shortcuts
• Shift + Left/Right: select by character
• Cmd + Shift + Left/Right: expand selection to line start/end…Show more
• Cmd + A: select the whole current command line
• Esc: clear selection and exit selection mode
• Backspace/Delete: delete selection first, otherwise keep normal behavior
Does your current terminal handle this well? If not, try the next Kaku release.
0:23Recently switched my main browser back from Edge to Helium. I thought I liked vertical tabs, but what I actually wanted was a minimal UI and maximum working space.
Helium now has vertical tabs…Show more, but the real highlight is compact mode. Address bar and tabs sit on the same row. Clean, tight, and space efficient.
Paired with my Maple theme and Maple bookmark extensions, the setup feels just right. Comfortable, focused, no noise.
Fully open source, privacy first, unbiased ad blocking, no bloat. Simple and lightweight. Highly recommended.
Mole 1.27 is live. The Mac cleaning tool that can free up tens of GBs in one go. 36K stars. github.com/tw93/Mole
Here’s what’s new:
· mo clean: adds safe cleanup for Group Containers, Maven local repo, Chrome and Google Updater caches, Expo ecosystem files…Show more, and improves npm residual detection with custom cache path support.
· mo purge: expands coverage for React Native and Expo targets including DerivedData, Pods, NDK, and .expo, with safer size handling and better trap behavior.
· mo status: prioritizes internal disks, improves layout during terminal resize, and fixes duplicate rendering in error states.
· Compatibility and stability: fixes macOS find argument handling and strengthens safe deletion paths with more consistent protection checks.
This release expands deep cleanup coverage across modern dev environments while keeping safety first. If Mole helps, I’d love your ideas on where to dig deeper for safe cleanup and more hidden junk.
🤱🏻 Pake v3.9 is now available. Turn any webpage into a desktop app with one command. 46K stars. github.com/tw93/Pake
This release is focused on cross-platform polish and shipping reliability.

Wow, I'm glad I could help you.
I recently came across a very cool tool called OpenTrace. It’s an open-source, visualized route tracing tool with a native cross-platform GUI for Windows, Linux, and macOS.
What makes it fun is that you can enter an IP or domain and actually see how traffic flows across nodes…Show more, step by step. It supports MTR-style tracing, custom DNS resolvers including DNS and DoH, CLI-triggered traces, local MMDB databases, and multiple languages. The UI feels familiar but adds much clearer visuals and explanations, which makes network paths far easier to understand.

If you use Claude Code, be sure to try the /plugin feature, then head to the Marketplaces and go crazy picking the plugins that suit you.
🎃Kaku v0.3 is out. A fast macOS terminal with great defaults, built for AI coding workflows. github.com/tw93/Kaku
This release is all about daily driver polish. Fullscreen feels solid, window restore is reliable across monitors…Show more, and a bunch of small workflow annoyances are gone.
Highlights
• Fullscreen is smoother with less flicker. Padding, tab bar, and split rendering stay correct
• Window restore now persists size and position, and restores correctly across multiple displays
• Finder and default terminal support. Open in Kaku from Finder, and set Kaku as the system default terminal
• Remote work is clearer. Tabs show SSH hostnames, and SSH is more compatible by using TERM xterm-256color
• UX feedback is explicit. Toast notifications for Copied and config reload
• Editing flow improvements. Selection autoscroll, shell history peek while staying inside vim or tmux
• Rendering and performance. Better font rendering for wide glyphs and Nerd Fonts, transparent window edge fix, lower GPU usage
• Power user details. Cmd K clears screen, Cmd Shift S toggles split direction, dictation works, Tab completion is back, kaku init auto-creates user config and can set an OpenCode theme, and kaku update is now safer with Homebrew
My workflow in Kaku
Left pane is my AI coding entry. On the right I keep two vertical splits: one for dev commands and debug runs, one for reviews and diffs. Tabs are one project per tab so it never gets messy, and I stay on shortcuts most of the time.
Mole 1.26 is live. The Mac cleaning tool that can free up tens of GBs in one go.
github.com/tw93/Mole
Here’s what’s new:
· mo clean: safer dev cleanup for Xcode, CoreSimulator, Cryptex, Flutter, plus clearer scan progress.…Show more
· mo uninstall: more complete removal with DiagnosticReports cleanup, full path preview, and better scan and metadata visibility.
· mo analyze: faster overview by skipping external disks by default, use mo analyze /Volumes when needed.
· mo purge: Vim style j and k navigation, improved path readability.
· UX and stability: consistent -h and –help, better Ghostty quick launch behavior, fixes for permission denied silent exits, plus new regression tests.
If Mole helps, I’d love your ideas on where to dig deeper for safe cleanup and more hidden junk.
You might replace your current terminal after trying this.
Kaku is now available. A Valentine’s gift for terminal nerds.…Show more
I started this while building Pake. I wanted a terminal that feels truly fast on macOS. That feeling got stronger during Mole. I tried everything: Alacritty is snappy but has no tabs. Ghostty’s font rendering never matched my taste. Warp requires a login. Kitty is powerful, but window management kept biting me.
Then I found WezTerm. It’s Rust-based and hackable, so I went in: removed a lot of legacy/compat modules, tightened the loading path, tuned macOS rendering, and baked in the small things I use every day.
The goal is simple: Alacritty-like speed with native tabs and splits. Built for AI coding. One pane for Claude Code, one for review, git diff at the bottom. Stay in flow.
A friend complained about terminals over dinner. I said “try mine.” I packaged it up and named it Kaku, Japanese, quick to say: Kaku Kaku Kaku Kaku.
It’s not fully mature yet, but I’ve daily-driven it for 6 months. No config needed. Try the shortcuts. File bugs when you find them.
是的 我也喜欢 这里后面会加更多玩法

I came across a project called Happy, a mobile and web client for Claude Code and Codex that lets you run your coding agent from anywhere.
It acts as a secure wrapper around Claude Code or Codex with end-to-end encryption, realtime voice support…Show more, and a fully featured UI. On your computer, you run happy instead of claude, or happy codex instead of codex. When you want to take over from your phone, it seamlessly restarts the session in remote mode. Press any key on your keyboard and control switches back instantly. It’s a clever way to make coding agents truly cross-device.
I’ve been looking for a tool like this for a long time, and FineTune finally checks all the boxes. It’s basically the volume mixer macOS should have shipped with: true per-app volume control with individual sliders and mute.…Show more
It also supports multi-device output, flexible audio routing, input and mic level control, a 10-band EQ with presets, pinned apps, and volume boost up to 400%, all in a lightweight menu bar app.
> brew install –cask finetune
I found a neat little tool called Snitch. It’s a prettier, more human-friendly way to inspect network connections, basically a nicer ss or netstat for humans.
Built in Go, it lets you inspect active connections through a clean TUI or well-styled tables…Show more, making network status much easier to read at a glance. If you like practical tools with good aesthetics, this one is worth trying.
> brew install snitch
I used to rely on anywhere to spin up a quick local server from any directory, but it hasn’t been updated in a long time. Recently I switched to Vercel’s serve, and it’s been a solid replacement.…Show more
serve is a simple static file server with clean directory listing support. It works well for serving a static site, an SPA, or just browsing files locally or on your LAN, with a neat, readable UI. If you need a lightweight static server, it’s worth trying.
> npm install –global serve

I like earnings charts more than price charts.
Sankey diagrams make it obvious how companies actually make money and spend it.
Mole, the Mac cleaning tool that can free up tens of GBs in one go, just got a new release, codename Velvet ✨
github.com/tw93/Mole
Here’s what’s new:
· mo uninstall: much faster app list loading, / filter + Ctrl+U, Homebrew cask uninstall now uses --zap…Show more, better leftover detection for Raycast, Zed, and Maestro, clearer failure diagnostics.
· mo clean: orphaned LaunchAgent cleanup, safer matching and counting, better scan performance, Gradle cache protected by default.
· mo analyze: fewer NFS-related hangs, better cache reuse and stale-first fast paint, deadlock fix for high fan-out scans.
· mo status: smarter proxy detection across env + system settings, with better tunnel awareness.
· mo purge / mo optimize / launcher scripts: more stable scan fallback, cleaner terminal behavior, better Raycast + Ghostty compatibility.

I recently came across a really beautiful Mermaid renderer and it immediately stood out. Compared to older Mermaid renderers, it feels much cleaner and easier on the eyes, with a level of polish that’s hard to ignore.…Show more
It’s called Beautiful Mermaid, an open-source diagram rendering library designed for the age of AI. It’s ultra-fast, fully themeable, and can output both SVG and ASCII. Built by the team at Craft, it’s a great example of how diagrams can be both functional and beautifully designed.
This morning I downloaded the ChatGPT Codex mac app with high expectations. The official video looked great, and I’ve always liked OpenAI’s product interactions, but after a deeper try the experience felt average…Show more, and I ended up uninstalling it with Mole. Compared to Claude Code CLI, the gap is still obvious.
I’ve seen many people argue that in AI coding, GUI will eventually beat TUI.
I see it the other way.
For professional developers, I believe TUI will dominate. Workflows like Claude Code, where everything is shell and everything is a command, make complex tasks easier to handle, keep code simpler, and make maintenance, iteration, and debugging much more straightforward. I still believe the future of serious AI coding belongs to TUI.
I recently found a handy tool for SVG work: SVG Viewer. It’s an in-browser editor where you paste an SVG, tweak the code, and see a live preview instantly. It also ships the essentials you actually need day to day: Optimize to shrink and clean up the SVG, Prettify to format it…Show more, quick transforms like rotate and flip, and exports for React, React Native, PNG, and Data URI.
What I like most is how frictionless it is for quick edits. If you need to adjust text, colors, or small details inside an SVG, it’s often faster than opening a full design tool. Paste, edit, optimize, export, done.
svgviewer.dev/
Tool UI is a React framework for conversation-native UIs. Tools return JSON, and Tool UI renders it as inline, narrated, referenceable surfaces inside messages, optimized for chat width and scroll. It’s schema-first:…Show more every surface is driven by a serializable schema with stable IDs, so results stay consistent and reusable.
It’s assistant-anchored and stack-agnostic, working with any LLM/provider and orchestration layer. If you’re building agents, it’s a clean bridge from tool outputs to real product UX.
