Have you tried the new Claude Code renderer? What has your experience been like?
If you haven't, you can enable it with: CLAUDE_CODE_NO_FLICKER=1 claude
Introducing Claude Managed Agents: everything you need to build and deploy agents at scale.
It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days.
Now in public beta on the Claude Platform.
Holy shit...someone just gave Claude a real browser.
Not screenshots.
Not brittle selectors.
Not slow MCP loops.
Real Playwright code — inside a sandbox.
It’s called dev-browser — and it lets AI agents control Chrome like developers do.
Here’s why this is different:
Instead of inventing new “agent syntax”,
dev-browser just lets AI write actual browser code.
goto
click
fill
evaluate
scrape
screenshot
Everything.
And it runs in a QuickJS sandbox — so the agent gets full browser control without touching your system.
That means:
• Real browser automation
• Zero host access risk
• Persistent tabs
• Multi-script workflows
• Connect to existing Chrome
• Full Playwright API
The key idea is simple:
The fastest way for an AI to use a browser
is to let it write browser code itself.
So an agent can literally:
Open X
Scroll
Extract tweets
Return JSON
All in one run.
No plugins.
No extensions.
No orchestration layer.
No MCP complexity.
Just:
install → tell Claude “use dev-browser” → done.
Even better, scripts run against persistent pages.
So agents can:
login once
navigate once
reuse context
continue workflows
Now you get things like:
• autonomous research agents
• AI QA testing websites
• scraping without MCP overhead
• multi-step browser workflows
• AI that actually uses web apps
• Claude operating real dashboards
And the security model is clean:
Playwright power
QuickJS sandbox
No filesystem access
No host execution
So agents are powerful — but contained.
Benchmarks are wild too:
Dev Browser
3m 53s
$0.88
29 turns
100% success
Faster and cheaper than typical setups like:
• Playwright MCP
• Chrome extensions
• browser skills
We’re moving from:
AI that looks at the web
→ AI that operates the web
That’s a big shift.
Because once AI can control browsers reliably,
it can use any software with a UI.
No API needed.
No integration required.
Just open the page — and work.
AI coworkers just got hands.
Computer use is now in Claude Code.
Claude can open your apps, click through your UI, and test what it built, right from the CLI.
Now in research preview on Pro and Max plans.
