Best API & Subscription for Claude Code

Claude Code speaks the Anthropic Messages API, which gives you three real ways to power it: the first-party Claude Pro/Max plans (best integration, but metered by a 5-hour session window plus weekly caps), Anthropic API billing (no windows, but the bill scales with every token), and — since August 2026 — Standard Compute's flat-rate endpoint, which serves Claude 5-family models over /v1/messages: set ANTHROPIC_BASE_URL to https://api.stdcmpt.com and Claude Code runs with no session windows and a fixed monthly price.

Cheapest tokens

Claude Pro ($20/mo) — if your Claude Code use is light-to-moderate, the first-party plan is the cheapest and most integrated way in. The window resets are the price.

If you need flat-rate / always-on

Standard Compute — heavy agentic sessions are exactly what hits the 5-hour and weekly windows; a flat rate with the same Anthropic-format API removes the meter with one environment variable. Claude 5-family models are served; if you need every Anthropic model variant, first-party API billing is the fallback.

Every option for Claude Code, compared honestly

OptionPriceThe honest take
Claude Pro / Max$20 / $100 / $200First-party and best-integrated — but metered by a rolling 5-hour session window plus weekly caps that heavy agentic sessions hit early. Max raises the caps, it doesn't remove them.
Anthropic API (pay-per-token)Pay-as-you-goNo plan windows — but the bill scales with usage, and agentic sessions re-send growing context every step, so heavy days get expensive fast.
Standard ComputeFLAT-RATE$39 / $89 / $249Flat-rate: no token meter, no 5-hour or weekly windows — and unlike the open-weight-only plans here, smart routing reaches the full frontier (Claude, GPT, Gemini class). Extreme sustained load is paced smoothly, not cut off. Wins when your agent runs all day or needs frontier quality that capped open-weight plans can't match.
GitHub Copilot Pro$10 / $39Cheap closed-model access (GPT/Claude/Gemini) with monthly premium-request allowances. Best if you want frontier models cheaply and lightly.

Disclosure: this guide is maintained by Standard Compute. We're one option among many above — genuinely the best fit only when your Claude Code runs heavy or always-on and the capped plans would stop it. For light or predictable use, the value multipliers above are often cheaper, and we say so.
