Claude Code is now available on the web.

So instead of loading up your terminal or having to open up your IDE anytime you want to make a change, you can now delegate coding tasks directly from your browser or the Claude mobile app.

You simply connect your GitHub account, you select your repo, describe what you need done, and Claude handles the rest, all running on our cloud infrastructure.

And the best part is you can now run multiple tasks in parallel across different repositories.

So whether you have a bug backlog, routine fixes, or a brilliant new idea or feature you want to add, you can just spin up a session or multiple sessions and let Claude handle them simultaneously.

Let me show you how this works.

So I'll open up Claude Code on the web at claude.ai/code.

I'll select a repo. I have a repo already selected here.

And then I'll give it a prompt. Let's say add input validation to the user registration endpoint.

Also make sure we're using a strong password on both the front end and backend API.

We'll hit enter and we are off to the races.

Claude is working in its own isolated sandbox with full git access and we can watch the progress in real time.

But while this runs, let me tell you about some of the other stuff that we've recently launched.

The big one is Claude Haiku 4.5.

And a few weeks ago, we launched Claude Sonnet 4.5, which became the world's best coding model.

And just last week, we followed it up with Claude Haiku 4.5.

And here's the really remarkable thing.

5 months ago, Sonnet 4 was state-of-the-art.

And now Haiku 4.5 gives you a similar coding performance at one-third the cost and more than twice the speed.

It even surpasses Sonnet 4 at certain tasks like computer use.

Now the benchmarks are impressive.

73.3% on Sweetbench verified, 41% on Terminal Bench, and it achieves 90% of Sonnet 4.5's performance in Agentic coding evaluations.

But the big question you're probably having is when should developers use Haiku 4.5?

And the big pattern that we're seeing from our community is that Sonnet 4.5 does the high-level problem decomposition and planning, and then Haiku 4.5 is used to actually implement and write the code.

Now this multi-agent approach is becoming really popular for things like large-scale refactors or tackling technical debt.

Haiku 4.5 is available wherever you get your Claude and it's available at just $1 per million input tokens and $5 per million output tokens.

All right, let's check back on our task and see how it's doing.

So, if we open it up here, we can see that Claude gave us a good summary of all of the changes that it made in the service.go go file in the TypeScript on the front end.

And my absolute favorite feature of Claude Code on the web is this open in CLI button.

And the reason that I really like it is you simply click it, you open up your terminal, paste in the command that it gave you, and now I am working in my local development environment with all of the context and all of my progress from the web preserved.

So, I can see the messages. I can see all of the files that have been changed.

I can go into VS Code and see all of the changes that were made to the service signup, the signup.typescript file, and much more.

And I can continue right from where I left off on my mobile phone or the browser.

Now, I want to show you one final feature that we recently added to Claude Code.

I gave it this prompt earlier talking about adding caching to my application, but I gave it a very broad prompt saying, "Hey, I would like to add caching to my application."

And what Claude Code did is it's going to ask me a number of follow-up questions to make sure that it implements it correctly.

So, it's going to ask the caching level here. Uh, should it be database query caching, API response caching?

And I can choose any of these, go to the next section and figure out what my goals are.

Is it to improve performance, reduce database load, the target area, is it for the workout data, for the user data, analytics, choose the technology, Redis, in-memory, PostgreSQL, and then I can hit submit and have it go and implement based on the follow-up information that I gave it.

And there you have it. Claude Code on the web for parallel cloud-based development at home and on the go.

Haiku 4.5 for lightning fast coding at a fraction of the cost and smarter local workflows with multi-question support.

Claude Code on the web is available now for pro and max users at claude.ai/code.

Give it a try and let us know what you think. Happy building.
