Download Claude: every app, every platform

Official download links and system requirements for every way to run Claude in 2026 - desktop apps, mobile apps, Claude Code, the Chrome extension and Microsoft 365 add-ins.

Every official way to get Claude in one place. Anthropic ships a web app at claude.ai, native apps for iOS, Android and ChromeOS, desktop apps for macOS 11+, Windows 10+ and Linux (beta), the Claude Code CLI for the terminal, a Chrome extension, Microsoft 365 add-ins, and Python and TypeScript SDKs. Everything below links to Anthropic's own properties.

This site hosts no installers, no APKs and no mirrors. If a page anywhere offers you a “Claude AI setup.exe”, it is not from Anthropic. The only safe sources are claude.com/download, the official app stores, and the signed package repositories documented at code.claude.com/docs.

#Where can I download Claude for my platform?

One table, every route. Nothing here needs a licence key: you install the client, then sign in with the account described on the Claude login page. Your plan travels with the account, not with the download.

#Which Claude download do you actually need?

Most people end up with two: the mobile app and one of web or desktop. Everything syncs through the account, so a conversation started on an iPhone continues on a laptop without any export step.

#How do I install Claude Code?

Claude Code is a command-line agent, not a GUI app, and it installs the way developer tools normally do. The native installer is the shortest path and is the only route that auto-updates in the background:

# macOS, Linux, WSL
curl -fsSL https://claude.ai/install.sh | bash

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

Package managers work too, and are the better choice on a machine you manage with configuration tooling. None of them auto-update by default, so you will need to run your own upgrade step:

System requirements are modest: macOS 13.0+, Windows 10 1809+ or Windows Server 2019+, Ubuntu 20.04+, Debian 10+ or Alpine 3.19+, on x64 or ARM64, with at least 4 GB of RAM and an internet connection. Two release channels exist - latest by default, and stable, which trails by roughly a week and skips major regressions. Release binaries are GPG-signed; macOS builds are notarized and signed by “Anthropic PBC”. If an install misbehaves, claude doctor prints a read-only diagnostic of your installation and settings.

#Installing the API SDKs

The SDKs are unrelated to the subscription apps. They talk to platform.claude.com using an API key and are billed per token, which is a separate bill from Pro or Max. Install one, export a key, and the first call is four lines:

pip install anthropic

from anthropic import Anthropic
client = Anthropic()  # reads ANTHROPIC_API_KEY

msg = client.messages.create(
    model="claude-sonnet-5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Summarise this contract clause."}],
)
print(msg.content[0].text)

The TypeScript package is @anthropic-ai/sdk and takes the same shape. Community SDKs exist for other languages but are not maintained by Anthropic. Rate limits, prompt caching and the Batch API - the three things that actually determine your bill - are covered on the Claude API page,.

#Legacy to current: updating hardcoded model strings

The most common reason a working Claude integration suddenly returns errors is a retired model ID. Anthropic removes old models on a published schedule, and a call to a retired string fails outright rather than silently falling back. If you have code written before 2026, check it against this table.

Migration is usually a one-line change, but two behavioural differences bite. First, temperature, top_p and top_k no longer work on Opus 4.7+ and Sonnet 5 - passing a non-default value returns a 400 error. Second, thinking is on by default on the current models and its depth is set by an effort parameter rather than a toggle. Both are explained on the extended and adaptive thinking page.

#What Anthropic does not ship

Worth knowing before you go looking. As of August 2026 there is no official Claude app for Windows on ARM Linux, no Firefox or Safari extension, no self-hosted or offline build, and no iPad-only variant - the iOS app covers iPhone and iPad from one binary. There is also no separate Claude Code subscription: it is bundled into the Pro, Max, Team and Enterprise plans, and there is no way to buy it alone.

Anything advertising a “Claude AI Pro crack”, a modified APK or a desktop installer from a download aggregator is malware or a scam. Anthropic distributes only through claude.com, claude.ai, the two mobile app stores, the Chrome Web Store, the Microsoft marketplaces and its own signed package repositories. If you need to connect Claude to your own systems, the supported mechanism is the Model Context Protocol - see MCP and Claude agents.
