AI Coding Plan Arbitrage Calculator

Help developers find the real cost and compliance risk between subscriptions and BYOK

Problem

A developer asked whether BYOK or a fixed subscription like Pro Max is cheaper for hobby projects, others discussed whether a Claude subscription can be used with third-party harnesses after confusing official messaging, and a third-party CLI claims prices 95%+ cheaper than direct official access with unclear sourcing and compliance.

Solution

A cost comparison calculator: input your model, estimated token volume, and usage pattern to see monthly costs across official subscriptions, BYOK direct, and various third-party plans, with compliance and terms risk labels. Tracks actual usage and suggests when to switch for savings.

Users

Heavy AI developers, indie hackers, and small teams torn between subscriptions and pay-as-you-go.

MVP

Input model and estimated tokens; compare official subscription, BYOK, and third-party monthly costs; label terms and compliance risks; track actual usage and suggest savings; export shareable comparison cards.

Revenue

Free basic calculator plus subscription for usage tracking, team comparison, historical trends, and recommendations.

Why now

AI coding plans are proliferating with frequent terms changes, and there is no trusted cross-vendor cost tool. A solo developer can start with a pure frontend and light data upkeep.
