ざっくりAWS is an unofficial AWS cost estimation website that aims to reduce complex AWS billing parameters into a small number of key inputs, then provide a rough monthly cost in Japanese yen. It covers common services such as EC2, Fargate, Lambda, S3, RDS, Aurora, DynamoDB, CloudFront, and API Gateway. The site clearly states that it is not an official tool, and that users should use AWS Pricing Calculator if they need accurate pricing.
The site’s main value lies in being fast and simplified. For example, the API Gateway page only asks for the number of requests, data transfer volume, and cache size to estimate monthly costs. Its calculation assumptions are disclosed fairly clearly: 30.5 days per month, pre-tax pricing, Tokyo region by default, and the North Virginia region for SES. AWS prices come from the Price List API, exchange rates come from exchangeratesapi, and the site states that data is updated daily at 10:00 AM. The page also displays the calculation function for API Gateway and provides links to the source code, unit tests, and E2E tests, making it more transparent than many similar small tools.
From a user perspective, there does not appear to be a paid pricing model; the site is supported by Google AdSense ads. The source code is public on GitHub, including the repositories nishinoshake/aws-rough and nishinoshake/aws-rough-functions. However, the main content does not include complete self-hosting instructions, nor does it state whether an external API or SDK is available. The author also mentions that the site is for sale due to declining willingness to maintain it, which means its long-term maintenance stability should be assessed carefully.
Its advantages are minimal input requirements, quick onboarding, pricing displayed in Japanese yen, and transparent calculation assumptions. It is suitable for developers, architects, or project leads who need to quickly gauge the approximate scale of AWS costs in the early stages of planning. The limitations are also clear: it only provides rough estimates, its region and configuration coverage is limited, and it cannot handle complex enterprise billing scenarios. The pages include ads, and because the results are unofficial, they should not be used as the final basis for procurement or budgeting.
The source content does not provide information on access, payment, or network availability from mainland China, so this remains unknown. If you need an official and accurate budget estimate, AWS Pricing Calculator should be the first choice. If you care about cost estimation for infrastructure as code, Infracost is worth considering. For cloud environments in China, use the official pricing calculator from the corresponding cloud provider.
