Use when evaluating Carbon for a C++ code base, running the carbon toolchain from a nightly or Bazel build, or comparing Carbon with staying on C++. Not for C++ modules: use cpp-modules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Carbon Carbon is an experimental successor language to C++ from the carbon-language project. As of 2026-09-05 there is no 1.0 and no 0.1: the 0.1 milestone is the minimum language for evaluation, and the 2025 roadmap revision moved its earliest realistic date to the end of 2026 after memory-safety design was added to its scope. The only downloads are nightly toolchain tarballs tagged `v0.0.0-0.nightly.YYYY.MM.DD`, on limited platforms. Treat every finding below as dated to the nightly you ran. ## Contract | Field | Bound contract | |---|---| | Trigger | A team with a large C++ code base asks whether to evaluate Carbon, wants to run the toolchain, wants to call C++ from Carbon, or asks how Carbon's safety model and readiness compare with C++. | | Authority | Reversible local: writes only the toolchain checkout or extracted nightly tarball, Carbon source files, and `--output` artifacts in the working directory; rollback is deleting them. No remote mutation. | | Side effect | A Bazel build of the toolchain compiles a pinned LLVM commit and takes substantial disk and time. | …

How to install
mdr add outlinedriven/outline-driven-development/carbon-lang@sha256:dd43ffcf2947645cThe line at the top of this page pins the label git:20260912.5c5b759, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
