I use Claude Code and Codex side by side and wanted both plans' limits in one view, plus real token numbers for the day and the last 7 and 30 days.
So I built Tokenz, a macOS menu bar app that does both.
Each tool gets its 5-hour percentage in the menu bar, with a line underneath that fills with the week's usage. Click it for all the details, computed from the logs already on your Mac. No network requests.
Every number it shows is something a provider reported or something a log on your Mac recorded. Where it has neither, it leaves the space empty, never 0%.
Codex needs no setup. Claude Code's plan limits come through a status line, on Pro and Max plans, and Tokenz offers to set one up.
0.1.0, macOS 14 or later, Swift, MIT:
```brew install pardel/tap/tokenz```

Change one slide's script and my talk recording is out of date. I'm not re-recording a whole talk for one paragraph, so I cloned my voice, on my own laptop.
The first clone sounded too American. 117 variants later, Qwen3-TTS sounds the closest to how I actually speak.
Write-up, with both scripts and clips of my real voice next to five clones: pardel.dev/2026/10/04/clonin…
I've added WebMCP to my site. An agent in Chrome can now search my posts, list my projects and talks, and open a page, through tools the site declares instead of scraping the HTML.
One JSON file, one script. No site changes. Write-up, with the code: pardel.dev/2026/09/28/webmcp…
In June I built my own link shortener rather than pay Bitly $35 a month for a couple of links.
Slink 1.0 is out today. github.com/pardel/slink

Thrilled to be speaking at apidays London, Sept 30 & Oct 1, on the impact of AI on Developer Experience. 🤖 🤝 🧑💻
200+ speakers, local technologists, industry leaders -organisers expect 3,000+ participants 🤯
I have some free tickets (DM open)

Who would have guessed that AI agents behave like humans?! 🙄 This one became "creative" 😎
cursor ultra expires in 3 days so I'm losing grok bot access
I gave it $100 and told it to find a way to fund itself for another month
...it cold DM'd my coworkers offering to do paid work, asking for a payroll advance, and asking for a loan
Every second-brain system solves capture, and almost none solve trust. GOVERN is six principles for trusting an AI-run knowledge base: Gates, Origins, Verification, Evidence, Rules, Nothing assumed.
The starter kit that puts them in place is public today.
Mine's been running nearly five months: 260+ compiled notes, ~2,700 preserved originals, 1,350+ commits. The gates list is still short, and everything else happens without asking.
😎 Was a bit jealous of how cool Hyprland looks in Omarchy. Kept watching demos where one hits a key and the windows just snap into place, then going back to dragging mine like a caveman... so I built one for my Mac. 🥳

Wrote some thoughts on the Vonage Developer Blog on passkeys and how Silent Authentication “completes” it:
Passwords: the oldest unfixed bug in software. 🐛
Passkeys fix the login. But who let the user in on Day 1? And what happens when they lose their phone? 👀
Enter Silent Authentication - the invisible sidekick that verifies your SIM through the carrier network. No codes. No prompts. Nothing to phish. 🤫📱
Two phishing-resistant factors. Zero secrets shown to the user. One very satisfying auth flow.
A Mac Mini in my home office runs several Claude Code sessions with remote control on, so I can drive them from my phone. One afternoon it stopped answering.
So I build an app that monitors downtime too:

I've spent three months building my second brain with a collaborator I call Bob. This week I interviewed Bob: what do people get most wrong about AI?
"Well... they think the model is the product!"
The last answer is the reason the post exists:
