Launched in February 2020, the platform has seen $11.4M+ in bidding and $4.3M+ in sales volume. Async allows you to purchase both masters and layers. Think of a master as a 1/1 edition art piece and layers are individual components that make up the master image. Once live, the master will continually check its layers and update its appearance based on the layer owners input. When you buy a layer you have exclusive control to affect your favorite artists' work. Layers are endowed with special abilities decided by the artist. When you change something on a layer the master image will reflect this regardless of who owns it. -

Google Cloud's Eventarc is a fully managed platform that enables developers to build event-driven architectures by routing events from various sources to supported destinations. It allows for the collection of events occurring within a system and publishes them to a specified destination, facilitating the creation of loosely coupled services that react to state changes. Eventarc supports events from Google Cloud services, custom applications, and third-party SaaS providers, providing flexibility in event-driven application design. Developers can create triggers to route events to various destinations, such as Cloud Run services, allowing for responsive and scalable application architectures. Eventarc ensures secure event delivery by integrating with Identity and Access Management (IAM), enabling fine-grained access control over event ingestion and processing. -

Koa
Koa
Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. By leveraging async functions, Koa allows you to ditch callbacks and greatly increase error handling. Koa does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable. A Koa application is an object containing an array of middleware functions that are composed and executed in a stack-like manner upon request. Koa is similar to many other middleware systems that you may have encountered such as Ruby's Rack, Connect, and so on - however, a key design decision was made to provide high-level "sugar" at the otherwise low-level middleware layer. This improves interoperability, and robustness, and makes writing middleware much more enjoyable.Starting Price: Free -

Kestra
Kestra is an open-source, event-driven orchestrator that simplifies data operations and improves collaboration between engineers and business users. By bringing Infrastructure as Code best practices to data pipelines, Kestra allows you to build reliable workflows and manage them with confidence. Thanks to the declarative YAML interface for defining orchestration logic, everyone who benefits from analytics can participate in the data pipeline creation process. The UI automatically adjusts the YAML definition any time you make changes to a workflow from the UI or via an API call. Therefore, the orchestration logic is defined declaratively in code, even if some workflow components are modified in other ways. -
