Claude Pro vs ChatGPT Plus
Two $20 seats, two first-party coding agents, and two different answers to the only question that matters — what happens when you hit the wall.
Updated August 28, 2026 · Independent comparison — Claude Pro, ChatGPT Plus are separate products.
Claude Pro
Anthropic's $20 seat, Claude Code included
Claude Pro is Anthropic's $20/month seat ($200/year, about $17/month) and it includes Claude Code. Usage runs on a rolling 5-hour session window stacked on a weekly cap, and — critically — chat, desktop, mobile and Claude Code all draw from the same pool, so a long conversation eats your coding budget. Anthropic does not publish numeric limits. Claude Fable 5 is not in the included weekly pool on Pro; it bills through usage credits at API rates instead. The product context window on individual plans is 200K.
ChatGPT Plus
OpenAI's $20 seat, Codex included
ChatGPT Plus is OpenAI's $20/month seat and the entry point for real Codex work — web, CLI, IDE and iOS — plus GPT-5.6 Sol, Terra and Luna. Its limit structure moved twice this year: OpenAI removed the 5-hour window on 2026-07-12 during a Sol traffic spike, then restored it for Plus on 2026-08-25, so Plus is once again capped on a 5-hour window stacked on a weekly one. Past either window you wait, or buy extra Codex credits on the token-based rate card. There is no annual billing.
Bottom line
Two $20 seats, two first-party coding agents, and two different answers to the only question that matters — what happens when you hit the wall. Choose Claude Pro if claude Code is the harness you want, with Opus 5 and Sonnet 5 behind it; choose ChatGPT Plus if codex across web, CLI, IDE and iOS matters more than any single model.

1DevToolOne window, every agent you're paying for
Whichever seat wins here, you end up locked to one vendor's harness — and most of these subscriptions are contractually barred from driving anything else. 1DevTool runs Claude Code, Codex CLI, Cline, OpenCode and Gemini CLI side by side in persistent terminals, so you can put each subscription behind the agent it's actually licensed for and switch between them without switching windows. It adds an HTTP client, a 13-engine database client and an embedded browser too. One-time $29, no subscription.
