ION ⚡
The C++ toolchain
you actually want.

One CLI for packaging, building, and linting C++ projects. Declare deps in ion.toml. Ship with confidence.

Why Ion?

EVERYTHING A C++ PROJECT NEEDS

Packaging, building, linting — one tool, one config file.

Cargo-style manifest

Declare every dependency in ion.toml. One lockfile, reproducible builds everywhere.

Multi-registry resolution

Resolve from the Ion registry, GitHub, ConanCenter, vcpkg, git URLs, or local paths — all in the same project.

Built in Rust

Lightning-fast resolution, caching, and build orchestration. No Python, no JVM, no warm-up.

Built-in linter

ion check catches memory leaks, use-after-free, null deref, and modern C++ anti-patterns before they ship.

LSP editor integration

ion lsp delivers diagnostics, code actions, and go-to-definition in any editor that speaks LSP.

Cross-platform

Linux, macOS, and Windows — one installer, same behaviour.

INSTALL IN SECONDS

curl -fsSL https://ion.cybergenii.com/install.sh | sh

The installer auto-detects your platform. Optional env vars: ION_INSTALL_DIR, ION_VERSION, ION_INSTALL_DEPS=0 to skip dependency bootstrapping. Full options →

60 seconds to your first build

FROM ZERO TO RUNNING IN 60 SECONDS

STEP 1

Create a project

$ ion new my-app --std 23

Scaffolds src/, include/, tests/, ion.toml, and CMakeLists.txt.

STEP 2

Add dependencies

$ ion add fmt spdlog

Resolves and locks versions in ion.lock. Conan/vcpkg names also work.

STEP 3

Build & run

$ ion build && ion run

Generates CMake, compiles with your system compiler, runs the binary.

STEP 4

Check code quality

$ ion check --fix

Static analysis with optional auto-fix. Use ion lsp for in-editor diagnostics.

CATCH BUGS BEFORE THE COMPILER DOES

Memory leaks, use-after-free, null derefs, and modern C++ anti-patterns — caught instantly via ion check or in your editor via LSP.
