Claude Max 5x vs Claude Max 20x
Identical models, identical features, identical cap structure. You are buying a multiplier — so the only honest question is how often you hit the current one.
Updated August 28, 2026 · Independent comparison — Claude Max 5x, Claude Max 20x are separate products.
Claude Max 5x
5x Pro usage at $100/month
Claude Max 5x is $100/month for five times Pro's usage per 5-hour session, plus a weekly all-models cap and a separate weekly per-model-group cap. It adds higher output limits, priority at peak times and early access to features, and it includes Claude Fable 5 for up to 50% of the weekly limit. It is monthly-only per Anthropic's help centre. The same shared-pool rule applies: extra Claude Code terminals do not get their own bucket, they just drain the weekly cap faster.
Claude Max 20x
20x Pro usage at $200/month
Claude Max 20x is $200/month for twenty times Pro's per-session usage, on the same weekly all-models and per-model-group caps as Max 5x. It is Anthropic's heaviest first-party seat and is marketed for long uninterrupted sessions, but it is explicitly not unlimited. Like every Claude plan it cannot legally drive a third-party agent — the OAuth token is licensed for claude.ai and Claude Code only — so if you want Cline or OpenCode you need a separate pay-as-you-go API key.
Bottom line
Max 5x and Max 20x are the same product at different allowances: the same models, the same Fable 5 inclusion at up to half the weekly limit, the same priority access, and the same three caps — a rolling 5-hour session limit, a weekly all-models cap and a separate weekly per-model-group cap. Max 5x gives five times Pro's per-session usage for $100/month; Max 20x gives twenty times for $200. Neither is unlimited, and neither gives extra Claude Code terminals their own bucket — parallel sessions drain the same weekly pool faster. Upgrade only if you are actually hitting the weekly cap on 5x; if you are hitting the 5-hour session limit instead, the extra $100 buys you a bigger session allowance but the same weekly ceiling shape.

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.
