Financial Flow is a cloud-native personal finance PWA built on AWS Amplify Gen 2, Cognito, AppSync GraphQL, and DynamoDB. Designed for salary-to-salary budgeting across custom financial cycles, it features automated debt carry-forward for unsettled payables/receivables, in-line math expression logging, instant profile sync, and full offline support - giving users complete control over multi-cycle budgets.

ForkPoint is a group decision app that ends the endless "where should we eat" debate. Friends join a live "Craving Lobby" with a short code, secretly rank their food mood (comfort, spicy, light, or treat), and optionally tell an AI chat about dietary needs or things to avoid.

A team-morale app built in 24 hours from the word CURRENT. One anonymous ping a day moves a live Canvas river from calm to storm, pushed to every open window over AppSync subscriptions. Pings carry no author and receipts carry no score, so anonymity is enforced by the schema rather than promised by the UI. Amplify Gen 2, DynamoDB, Lambda, Cognito, and Bedrock underneath.

Provides an overview of API Gateway custom domain names for private APIs.

Developers can connect Lambda functions, DynamoDB tables, and other resources to create sophisticated real-time applications with features like data transformation, persistent storage, and validation.

Real-time features have become essential in modern applications. Whether you’re building collaborative tools, live dashboards, or interactive games, users have come to expect instant and seamless upda...

This post demonstrates how integrating an Amazon Bedrock streaming API with AWS AppSync subscriptions significantly enhances AI assistant responsiveness and user satisfaction. By implementing this streaming approach, the global financial services organization reduced initial response times for complex queries by approximately 75%—from 10 seconds to just 2–3 seconds—empowering users to view responses as they’re generated rather than waiting for complete answers.

AWS Amplify now supports seeding data across Amazon Cognito, AWS AppSync, Amazon DynamoDB, and Amazon S3. Developers can programmatically create test users and associated resources through new APIs and a CLI command. This feature simplifies testing and development workflows by enabling quick population of auth-dependent resources. Create Cognito users, seed DynamoDB records via AppSync with user context, and upload S3 objects - all while maintaining proper authentication relationships. This eliminates manual user creation and authentication steps previously required for testing auth-protected resources. This feature is available in all regions where AWS Amplify is supported. To learn more about implementing auth-dependent data seeding in your application, visit the AWS Amplify documentation for seeding.

Starting today, AWS AppSync Events, a fully managed service for serverless WebSocket APIs with full connection management, now supports data source integrations for channel namespaces. This new feature enables developers to associate AWS Lambda functions, Amazon DynamoDB tables, Amazon Aurora databases, and other data sources with channel namespace handlers to process published events and subscription requests. Developers can now connect directly to Lambda functions without writing code and leverage both request/response and event modes for synchronous and asynchronous operations. With these new capabilities, developers can create sophisticated event processing workflows by transforming and filtering published events using Lambda functions, or save batches of events to DynamoDB using the new AppSyncJS batch utilities for DynamoDB. This integration enables complex interactive flows, making it easier for developers to build rich, real-time applications with features like data validation, event transformation, and persistent storage of events. By simplifying the architecture of real-time applications, this enhancement significantly reduces development time and operational overhead for front-end web and mobile development. This feature is now available in all AWS Regions where AWS AppSync is offered, providing developers worldwide with access to these powerful new integration capabilities. Powertools for AWS Lambda new AppSync Events integration are also now available to easily write your Lambda functions. To learn more about AWS AppSync Events and channel namespace integrations, visit the launch blog post, the AWS AppSync documentation, and the Powertools for Lambda documentation (TypeScript, Python, .NET). You can get started with these new features through the AWS AppSync console.
