AI tool comparison (uptime & outage trends)

ChatGPT (OpenAI) and Claude (Anthropic) are the two leading generative-AI chat services. On this page we line up their current status and uptime (our own estimate) live in the table above, then explain how their outages differ and how to switch when one of them goes down.

Claude Code (Anthropic) and Codex (OpenAI) are leading AI coding agents that run in your terminal or editor. Because both depend on an upstream API (Claude API / OpenAI API), their outages share some traits and differ in others. Check each one's current status in the table above as we lay out the differences and how to switch.

The OpenAI API and Claude API are LLM APIs widely used as the backend for production apps. Because availability directly affects your business, it is important to understand both providers' outage patterns and design your fallback accordingly. Check the current status in the table above as we lay out the differences.

Cursor and GitHub Copilot are leading AI coding aids inside the editor. Cursor uses its own IDE plus a cloud Agent, while Copilot is an extension for VS Code and others backed by GitHub's infrastructure, so their setups differ and so do their outages. Check the current status in the table above as we lay out the differences.

We line up the current status and uptime (our own estimate) of the four major AI coding tools (Claude Code / Codex / Cursor / GitHub Copilot) in the table above. It is a comparison to help you quickly pick "which one works right now" when your development stalls.

Gemini (Google) and ChatGPT (OpenAI) are the leading free-to-use generative-AI chat services. This page lines up their current status and uptime (our own estimate) live in the table above, then explains how their outages differ and how to switch when one is struggling.

Claude (Anthropic) and Gemini (Google) are generative-AI chats strong at long-form reading, writing, and summarizing. They run on different providers (Anthropic / Google), so their outages surface differently. Check both services' current status and uptime (our own estimate) in the table above, then read how they differ and how to switch.

Perplexity is a search-focused AI that answers with cited sources, while ChatGPT (OpenAI) is a general-purpose generative-AI chat. Their uses overlap, but their architecture and dependencies differ, so their outages surface differently. Check both services' current status and uptime (our own estimate) in the table above, then read how they differ and how to switch.
