Apache Flink
Stream processing framework with powerful stream
Apache Flink is a distributed engine for stateful computations over data streams and batches, designed for low-latency processing at scale. Its core runtime executes dataflow graphs with fine-grained backpressure and checkpointing, allowing applications to recover consistently from failures. Flink’s event-time model and watermarks enable accurate out-of-order processing, windowing, and complex time semantics that typical real-time systems struggle with. Developers program against high-level APIs—DataStream and Table/SQL—to express transformations, joins, and stateful patterns, while specialized libraries support CEP, machine learning workflows, and connectors. A rich connector ecosystem integrates with systems like Kafka, Kinesis, filesystems, JDBC sources/sinks, and object stores. Deployments span Kubernetes, YARN, Mesos, and standalone clusters, and operational features such as savepoints, state backends, and metrics make long-running jobs manageable in production. -

Auto
A collection of source code generators for Java
Auto is a collection of source code generators for Java. Java is full of code that is mechanical, repetitive, typically untested and sometimes the source of subtle bugs. Sounds like a job for robots! The Auto subprojects are a collection of code generators that automate those types of tasks. They create the code you would have written, but without the bugs. Save time. Save code. Save sanity. Some of Auto subprojects are AutoFactory, JSR-330-compatible factories, AutoService, provider-configuration files for ServiceLoader, AutoValue, immutable value-type code generation for Java 7+, and Common, helper utilities for writing annotation processors. Auto is licensed under the Apache License, Version 2.0. -

BIMserver
The open source BIMserver platform
The Building Information Model server (short: BIMserver) enables you to store and manage the information of a construction (or other building related) project. Data is stored in the open data standard IFC. The BIMserver is not a fileserver, but it uses a model-driven architecture approach. This means that IFC data is stored as objects. You could see BIMserver as an IFC database, with special extra features like model checking, versioning, project structures, merging, etc. The main advantage of this approach is the ability to query, merge and filter the BIM model and generate IFC output (i.e. files) on the fly. Thanks to its multi-user support, multiple people can work on their own part of the dataset, while the complete dataset is updated on the fly. Other users can get notifications when the model (or a part of it) is updated. -

Bastillion
Web-based SSH console that centrally manages administrative access
Bastillion is a web-based SSH console that centrally manages administrative access to systems. Web-based administration is combined with the management and distribution of user's public SSH keys. Key management and administration is based on profiles assigned to defined users. Administrators can login using two-factor authentication with Authy or Google Authenticator. From there they can manage their public SSH keys or connect to their systems through a web-shell. Commands can be shared across shells to make patching easier and eliminate redundant command execution. Bastillion layers TLS/SSL on top of SSH and acts as a bastion host for administration. Protocols are stacked (TLS/SSL + SSH) so infrastructure cannot be exposed through tunneling / port forwarding. -

BinExport
Export disassemblies into Protocol Buffers
BinExport is a disassembly export plugin developed by Google as part of the BinDiff ecosystem, designed for reverse engineering and binary analysis. It works with popular disassemblers including IDA Pro, Binary Ninja, and Ghidra, enabling the export of disassembly data into a structured Protocol Buffer format. This exported data can then be used for binary comparison, diffing, and advanced analysis tasks through BinDiff or other compatible tools. BinExport captures detailed information such as instructions, functions, control flow graphs, and metadata, providing a machine-readable representation of a program’s disassembled structure. It supports multiple export formats, including binary, text, and statistics outputs, and can be used interactively or via scripting (IDC, IDAPython, or Ghidra’s headless mode). The project includes complete build instructions for Linux, macOS, and Windows, ensuring reproducibility across platforms. -

ButterKnife
Bind Android views and callbacks to fields and methods
ButterKnife is an annotation-based view binding library for Android that reduces boilerplate in Activities, Fragments, and custom views. Developers replace repetitive findViewById calls with BindView fields and define UI event handlers using annotations like @OnClick, with the library generating efficient binding code at compile time. Because it relies on annotation processing, there’s no reflection at runtime, keeping startup paths lean and predictable. The generated bind/unbind lifecycle helps avoid memory leaks by clearing references when views are destroyed. Butter Knife made UI code more readable and maintainable for years, especially in large codebases with complex layouts and many event hooks. While newer Android APIs now offer official view binding alternatives, the project remains a landmark example of how code generation can simplify everyday Android development. -

EasyExcel
Lightweight Java library developed by Alibaba for reading and writing
EasyExcel is a Java library focused on reading and writing Excel files with very low memory usage, making it suitable for large datasets that overwhelm traditional APIs. It uses streaming/event-driven parsing to avoid loading entire workbooks into memory, and it maps rows to Java objects via simple annotations. Writers support multiple sheets, custom styles, merged cells, and template-based filling so production reports remain maintainable. The API emphasizes developer ergonomics: callbacks are straightforward, converters handle common type transformations, and header/column mapping is explicit. It integrates cleanly into Spring/enterprise stacks, often as part of import/export pipelines or scheduled report generation. By optimizing both performance and ease of use, EasyExcel reduces operational risk around big Excel jobs in web services and back-office tools. -

Feign
Make writing Java http clients easier
Feign is a Java to HTTP client binder that was built primarily to make writing Java http clients easier. Inspired by previous projects Retrofit, JAXRS-2.0 and WebSocket, Feign was designed to reduce the complexity that is often involved in binding the Denominator uniformly to HTTP APIs, no matter the ReSTfulness. Feign works by processing annotations into a templatized request, to which arguments are applied in a straightforward manner before output. While it may only support text-based APIs, it simplifies system aspects dramatically and makes it much easier to unit test your conversions. Feign makes use of great tools like Jersey and CXF for writing Java clients for ReST or SOAP services. It also lets you write your own code on top of http libraries, and connects your code to http APIs with little overhead. -

FreeRTOS BLE Mobile SDK for Android
Android SDK for FreeRTOS Bluetooth Devices
Using the Android SDK for FreeRTOS Bluetooth Devices, you can create mobile applications that do the following. Scan for and connect to nearby BLE devices running FreeRTOS. Perform WiFi provisioning of the FreeRTOS BLE devices after connecting to them ( Only supported for Espressif ESP32-DevKitC ). Act as a proxy for transmitting MQTT messages between a device running FreeRTOS and the AWS IoT cloud. The SDK includes some functions that help you perform BLE operations with FreeRTOS devices. Once the connection to the device is established, you get an AmazonFreeRTOSDevice object, and you can use this object to do WiFi provisioning or Mqtt proxy. The MQTT proxy service controls the MQTT proxy. It allows the device to send and receive MQTT messages from the AWS IoT cloud through the phone, when this feature is enabled. The SDK includes a demo application that demonstrates some of the main features of the SDK. -

GraphQL SPQR
Build a GraphQL service in seconds
GraphQL SPQR (GraphQL Schema Publisher & Query Resolver, pronounced like speaker) is a simple-to-use library for rapid development of GraphQL APIs in Java. GraphQL SPQR aims to make it dead simple to add a GraphQL API to any Java project. It works by dynamically generating a GraphQL schema from Java code. When developing GraphQL-enabled applications it is common to define the schema first and hook up the business logic later. This is known as the schema-first style. While it has its advantages, in strongly and statically typed languages, like Java, it leads to a lot of duplication. Both of these blocks contain the exact same information. Worse yet, changing one requires an immediate change to the other. This makes refactoring risky and cumbersome, and the compiler can not help. On the other hand, if you’re trying to introduce a GraphQL API into an existing project, writing the schema practically means re-describing the entire existing model. -

JSweet
A Java to JavaScript transpiler
JSweet leverages TypeScript to write rich and responsive Web applications in Java through the use of JavaScript libraries and frameworks. With JSweet, Java programs are transpiled (source-to-source compiled) to TypeScript and JavaScript for being run in browsers, mobile Web views, or in Node.js. It provides web applications with type-checking and generates fully type-checked JavaScript programs. It stands on Oracle's Java Compiler (javac) and on Microsoft's TypeScript (tsc). JSweet depends on well-typed descriptions of JavaScript APIs, so-called "candies", most of them being automatically generated from TypeScript definition files. These API descriptions in Java can be seen as headers (similarly to *.h header files in C) to bridge JavaSript libraries from Java. There are several sources of candies for existing libraries and you can easily build a candy for any library out there. -
