WHAT IT’S REALLY ABOUT
Claude Code goes web-based; Haiku 4.5 boosts speed, cost
- Claude Code is now accessible via browser and mobile, letting users delegate coding tasks by connecting GitHub and selecting a repository without opening a local IDE.
- The web version runs tasks in isolated cloud sandboxes with Git access and supports parallel sessions across multiple repositories for handling backlogs and feature work simultaneously.
- Claude Haiku 4.5 is introduced as a high-speed, lower-cost model that delivers near–Sonnet 4.5 agentic coding performance and can outperform older Sonnet versions on certain tasks.
- A recommended workflow pattern is to use Sonnet 4.5 for planning and decomposition, then Haiku 4.5 for implementation—especially effective for refactors and tech-debt paydown.
- Claude Code on the web can “teleport” work back to local development via an “Open in CLI” handoff that preserves context and changes, plus it can ask structured follow-up questions to refine vague requests.
IDEAS WORTH REMEMBERING
5 ideasClaude Code web removes the local setup barrier for quick changes.
Instead of launching a terminal or IDE, you can start coding tasks from claude.ai/code or mobile by connecting GitHub, choosing a repo, and describing the change.
Parallel sessions turn Claude Code into a backlog-clearing “task runner.”
Because you can run multiple tasks at once across different repositories, it’s positioned for handling routine fixes, bugs, and small feature additions concurrently.
Haiku 4.5 targets “implementation at scale” with strong price-performance.
Anthropic positions Haiku 4.5 as delivering similar performance to earlier state-of-the-art models at roughly one-third the cost and more than twice the speed, with stated benchmark results and 90% of Sonnet 4.5’s agentic coding performance.
Use Sonnet for thinking, Haiku for typing—an emerging community best practice.
The transcript highlights a multi-agent pattern where Sonnet 4.5 handles decomposition and planning while Haiku 4.5 executes code changes, particularly useful for large refactors and technical debt.
“Open in CLI” preserves momentum when switching from cloud to local.
After cloud execution, a single command lets you continue locally with the full conversation context and modified files available in your local tools (e.g., VS Code).
WORDS WORTH SAVING
5 quotesClaude 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.

Five months ago, Sonnet four 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.
— Unknown
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.

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