Claude is an AI assistant developed by Anthropic. It handles conversations, writing, coding, and analysis through the claude.ai website, mobile apps, and a developer API. When something goes wrong, it usually shows up as failed logins, slow or incomplete replies, or errors in the API and related tools like Claude Code. This page tracks current status and recent incident history so you can tell quickly whether the problem is on Anthropic's side or yours.
Claude is a family of large language models built by Anthropic, available as a chat interface, a developer API, and developer tools such as Claude Code. You can use it through the web app at claude.ai or integrate it into your own software. Common trouble spots include login and account access, conversations that stall or return errors, rate limits on the API, and occasional downtime during high demand. If Claude stops responding or replies look cut off, first check your internet connection and try a fresh browser session. Confirm you are signed in with the right account, clear cached credentials if the login loop repeats, and check your API key and usage limits if you are calling the API. If everything on your side looks fine, the issue is likely on Anthropic's end and should show up here.
