GRiSP Software enables running Erlang/Elixir on embedded systems, including microcontrollers and embedded Linux, offering deterministic and real-time runtime environments that boot directly into the BEAM VM. It provides three purpose-built open-source software stacks: 1. GRiSP Metal: Runs Erlang/Elixir on RTEMS, optimized for microcontrollers with a small footprint (fits in 16 MB RAM), real-time scheduling, predictable I/O, and direct hardware access. It offers supervision trees for reliability at the edge. 2. GRiSP Alloy: Boots Erlang/Elixir on a minimal real-time Linux image built with Buildroot. Supports multiple Erlang/Elixir VMs with priority and core pinning, secure local distributed Erlang links, and full Linux driver and networking access, with fast boot and a small attack surface. 3. GRiSP Forge: Similar architecture to Alloy but based on Yocto, targeted at teams needing customizable and long-term Linux stacks with BSP integration. It supports multiple VMs, efficient secure Erlang nodes, industrial Linux tooling, and enterprise-grade lifecycle features. GRiSP-io is a cloud and edge platform for managing, monitoring, and deploying GRiSP-based embedded systems remotely. It offers remote updates, real-time performance insights, and integrates cloud and edge control, helping customers scale deployments from prototypes to large fleets. Benefits of using GRiSP software include efficient, scalable, and fault-tolerant development on embedded platforms. It reduces complexity for developers by enabling Erlang/Elixir on bare metal or embedded Linux with real-time capabilities. For IoT and industrial systems, it supports automation, robotics, and connected devices, complemented by GRiSP-io for management and monitoring. GRiSP is an open-source project by Peer Stritzinger GmbH, with resources and code available on GitHub, a dedicated SaaS platform at GRiSP.io, and further support provided by the company based in Germany.
