KitchenCost is a recipe costing and menu pricing app built for chefs, bakers, caterers, food trucks, cafes, and small restaurants that need clear numbers without spreadsheet chaos. Instead of recalculating costs manually every time an ingredient price changes, you create ingredients once, build recipes from them, and instantly see total cost, cost per serving, food cost %, and a suggested selling price based on your target margin.

The app also supports reusable sub-recipes, which makes it easier to manage prep components like sauces, doughs, fillings, and dressings across multiple menu items. That means pricing stays more accurate as your menu grows and updates become much easier to manage.

KitchenCost is designed to be practical for day-to-day operations. It works offline by default, does not require an account to get started, and keeps data on your device unless you choose to enable sync. For independent chefs and small food businesses, it offers a simpler way to price confidently, save time, and keep margins visible.

KitchenCost.app features and specs

  • Recipe costing
    Add ingredient prices, quantities, and units once, then instantly calculate total recipe cost, cost per serving, and ingredient-level breakdowns.
  • Target-based pricing
    Set a target food cost or margin and get a suggested selling price so you can price menu items with more confidence.
  • Reusable sub-recipes
    Build components like sauces, doughs, fillings, and dressings as sub-recipes and reuse them across multiple dishes.
  • Offline-first setup
    Start without an account, keep data on your device by default, and enable sync only when you choose to.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.
