Ferrocene is a Rust compiler toolchain for embedded, safety-critical and mission-critical systems. The vendor states that it is qualified by TÜV SÜD for development under ISO 26262 (automotive), IEC 61508 (industrial) and IEC 62304 (medical software), and that it supports Linux, QNX and bare-metal Arm and x86-64 targets. The toolchain is distributed as open source under the MIT or Apache-2.0 licence, including the qualification documents, on a quarterly release cycle. Commercial support and work on custom targets are offered alongside it.
Ferrocene is developed by Ferrous Systems GmbH, whose legal notice gives an address in Berlin, Germany, and lists its managing directors. The legal notice names no parent company. Because the compiler is open source and its qualification documents are published, a European organisation can inspect the toolchain, build it itself and run it on its own infrastructure. This reduces dependence on proprietary compiler vendors, although commercial support comes from the company itself.
