20SCore

20SCore is an open-source software framework designed to provide a compact, modular core for building scalable applications. It aims to minimize runtime footprint while delivering essential services such as configuration, logging, task scheduling, and inter-component communication. The project emphasizes cross-language bindings and cross-platform portability, enabling developers to deploy modules written in supported languages on various operating systems.

It was initiated by 20S Labs and released to the public in 2020. Since then, versions have been released under a permissive license, with ongoing development and community contributions. The project positions itself as a lightweight alternative to larger application frameworks for embedded, edge, and cloud-native use cases.

The core consists of a runtime engine that hosts modular plugins. Modules implement a defined plugin interface and register with the core during startup. Communication between modules is handled via a built-in message bus or through direct bindings, depending on configuration. The design favors a minimal, well-documented API and a clear separation between the core and ecosystem modules.

Key features include a pluggable configuration system, structured logging, a task scheduler, and a simple dependency-injection mechanism. The ecosystem provides language bindings for C++, Python, and Rust, along with a growing catalog of community modules for data processing, networking, and I/O.

20SCore is released under the MIT license and is widely used in education and small-to-medium-scale projects. Critics note a smaller ecosystem and fewer third-party integrations than larger frameworks, but praise its clarity, small footprint, and ease of embedding in constrained environments.
