We've re-built Conductor from scratch to make it twice as fast.
Creating tabs, switching workspaces, and rendering files are all 50% faster, memory usage is lower, and the app is 150 MB smaller.
Introducing Conductor Allegro!
A Rust dev just killed Headless Chrome.
It's called Obscura. The open-source headless browser purpose-built for AI agents and scrapers at scale.
Chrome vs Obscura:
- Memory: 200MB+ → 30MB
- Binary: 300MB+ → 70MB
- Page load: 500ms → 85ms
- Startup: 2s → Instant
- Anti-detect: None → Built-in
Single binary. No Node, no Chrome, no dependencies.
Stealth mode is brutal:
→ Per-session fingerprint randomization (GPU, canvas, audio, battery)
→ 3,520 tracker domains blocked by default
→ navigator.webdriver masked to match real Chrome
→ Native function masking so detectors can't sniff it out
Drop-in replacement for Puppeteer and Playwright over CDP. Zero code changes.
If you run agents or serious scraping at scale, this repo prints money.
100% Opensource.
Introducing Tolaria! 💧
Today I am releasing a macOS desktop app for managing markdown knowledge bases, and helping both AI and humans operate them.
It’s free and open source, and always will be.
I have been working on it for three months, and I now use it to run my life and work. I personally have a massive workspace of 10,000 notes — the result of 6 years of Refactoring — which I now operate on Tolaria.
Tolaria is the main collaboration surface with my AI agents: they create new notes there, connect them to what exists, and edit existing ones. Everything is easy to understand for them, because it’s just markdown files. In a way, it’s my implementation of @karpathy's LLM wiki.
Tolaria is also the biggest experiment I have ever run about writing software with AI:
• 2000 commits
• 100K+ lines of code
• 3000+ tests / 85% coverage
• 9.9/10 code health
• 70+ architecture decision records
I am releasing it open source also to use it as a living artifact of how I do AI coding, so you can inspect at any time things like how I write docs, what's in my AGENTS file, what hooks do I run, and so on. You can find it below:

Introducing @21st_dev Agent Elements
Diffed edits. Plan approvals. Clarifying questions. Sub-agents. Tool cards. The pieces every "agent UI" lib skips.
25 @shadcn /ui components built for the new generation of agents that use your computer.
Open-source. Link in thread 🧵
just got the email from @jonpaul, https://t.co/BB4Mi8m4w6, they were building something I've been dreamed of for a long time... A new WYSIWYG, Watch out for their news tomorrow!
