Propeller is a lightweight orchestration platform developed by Abstract Machines in the context of the ELASTIC project. It enables secure, event-driven deployment and execution of WebAssembly (Wasm) workloads across heterogeneous cloud, edge, and IoT environments — including microcontrollers running RTOS.
Key features include:
- Fast, low-overhead orchestration of serverless (FaaS) workloads
- Support for resource-constrained devices (e.g. ESP32, Zephyr RTOS)
- Secure multi-protocol messaging via the built-in SuperMQ
- OCI-compliant Wasm artefact handling
- No dependency on Kubernetes or heavyweight control planes
Propeller is used in both ELASTIC Demonstrator 1 (6G IoT data fabric services) and Demonstrator 2 (secure workload migration across trust boundaries).

Wasm Operator is a platform to run Kubernetes Operators as Wasm components that only wake up when there are changes to be processed. This reduces their memory footprint and enhances efficiency for edge orchestration.

NETTO is an eBPF-powered network monitoring tool for Linux that focuses on measuring the CPU utilization of the key kernel tasks responsible for running the network stack. Thanks to a lightweight profiling-centric design, NETTO can provide a detailed breakdown of the low-level kernel runtime operations with minimal and configurable system overhead. NETTO is an essential tool for system administrators that wish to understand their servers’ CPU time allocation, and optimize the networking configuration around it.

Pretty Verifier is a static analysis tool for eBPF C code, developed to detect and explain security issues that would cause verifier rejections in the Linux kernel. It provides early error reporting, clear diagnostic messages, and fix suggestions, based on combined analysis of the C source, compiled object code, and verifier logs. Developed within the ELASTIC project (Task 1.3), the tool helps developers write eBPF programs that comply with verifier constraints and security requirements.
