Best API & Subscription for Aider

Aider is already lean, so the plan choice is mostly about model access: OpenCode Go for cheap open-weight value, GitHub Copilot Pro or OpenRouter for frontier models pay-as-you-go. If you run Aider heavily across big repos, Standard Compute's unlimited flat-rate caps the bill.

OpenCode Go, paired with Aider's --weak-model for the cheap chores.

If you need unlimited / always-on

Standard Compute for heavy repo-map-heavy sessions that would otherwise scale per-token.

Every option for Aider, compared honestly

OptionPriceThe honest take
OpenCode Go$10/mo ($5 first month)Best raw open-weight value: ~$60/mo of usage for $10 (~6x). Capped by $12/5h + $30/week windows. Works with any agent.
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.
OpenRouterPay-as-you-go400+ models, ~5.5% fee, no markup on inference. Maximum flexibility, not a subscription — bill scales with usage, so heavy agents get expensive.
Standard ComputeUNLIMITED$9 / $39 / $99 / $399Unlimited: 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.
GLM Coding Plan (Z.ai)$18 / $72 / $160GLM-5.2-only on prompt-count windows. Good if GLM quality covers you; quota burns 2-3x faster at peak.

Disclosure: this guide is maintained by Standard Compute. We're one option among many above — genuinely the best fit only when your Aider 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.
