Accent CMS

Accent CMS is a high-performance markdown CMS in a single binary, written in Rust. It serves markdown files as HTML with on-the-fly rendering, caching, Jinja-style templating, WASM plugins, image processing, client-side search, diagrams, and an admin authoring UI.

This repository is the official download location for Accent CMS release binaries. Product information, documentation, and pricing live at accentcms.dev.

Install

One binary per platform: every download contains the full feature set, and your license key decides which tier is unlocked at runtime. Building a site (accent build) and the development server (accent serve) are free and need no license key at all.

Linux and macOS

curl -fsSL https://raw.githubusercontent.com/AccentCMS/accent/main/install.sh | sh

Re-running the installer when Accent CMS is already current reports "Already up to date" and changes nothing. To reinstall or update in place, pass force -- note that in the piped form, flags must go to sh, not to curl (a flag placed after the URL is consumed by curl):

curl -fsSL https://raw.githubusercontent.com/AccentCMS/accent/main/install.sh | sh -s -- --force
# or, using the environment-variable form:
curl -fsSL https://raw.githubusercontent.com/AccentCMS/accent/main/install.sh | ACCENT_FORCE=1 sh

To install a specific version, use --version v0.23.1 (via sh -s --) or ACCENT_VERSION=v0.23.1; the v prefix is optional.

Windows (PowerShell)

irm https://raw.githubusercontent.com/AccentCMS/accent/main/install.ps1 | iex

Re-running the installer when Accent CMS is already current reports "Already up to date" and changes nothing. The piped form cannot receive parameters at all, so the installer honors environment variables set in the same session before the pipe:

# Reinstall or update in place
$env:ACCENT_FORCE = "1"; irm https://raw.githubusercontent.com/AccentCMS/accent/main/install.ps1 | iex

# Install a specific version (the v prefix is optional)
$env:ACCENT_VERSION = "v0.23.1"; irm https://raw.githubusercontent.com/AccentCMS/accent/main/install.ps1 | iex

$env:ACCENT_FORCE stays set for the rest of the session; Remove-Item Env:ACCENT_FORCE clears it. Any value other than empty or "0" counts as force. The parameterized form is also available, and an explicit parameter always wins over its environment variable:

& ([scriptblock]::Create((irm https://raw.githubusercontent.com/AccentCMS/accent/main/install.ps1))) -Version v0.23.1 -Force

Manual download

Grab the archive for your platform from the latest release:

Platform	Archive
Linux x86_64	accent-<version>-x86_64-unknown-linux-gnu.tar.gz
Linux ARM64	accent-<version>-aarch64-unknown-linux-gnu.tar.gz
macOS Intel	accent-<version>-x86_64-apple-darwin.tar.gz
macOS Apple Silicon	accent-<version>-aarch64-apple-darwin.tar.gz
Windows x86_64	accent-<version>-x86_64-pc-windows-msvc.zip
Windows ARM64	accent-<version>-aarch64-pc-windows-msvc.zip

Stable URLs for automation follow the pattern:

https://github.com/AccentCMS/accent/releases/latest/download/<asset-name>

Verifying your download

Every release ships a checksums-<version>.txt covering all archives, plus a detached GPG signature checksums-<version>.txt.asc made with the Accent CMS release signing key (release-signing-key.asc in this repository).

# 0. One-time: import the release signing key
curl -fsSLO https://raw.githubusercontent.com/AccentCMS/accent/main/release-signing-key.asc
gpg --import release-signing-key.asc

# 1. Verify the signature on the checksums file
gpg --verify checksums-<version>.txt.asc checksums-<version>.txt

# 2. Verify the downloaded archive against the checksums
sha256sum -c --ignore-missing checksums-<version>.txt

The Linux/macOS install script performs both steps automatically when gpg is on your PATH, and always verifies the SHA-256 checksum.

Publication attestation

On every release, a workflow in this repository re-runs the verification above and records a signed attestation in the Sigstore transparency log. This is a publication attestation -- it proves the exact bytes were published here and passed signature verification, with the GPG signature as the primary trust root (builds happen in a private repository, so build provenance is not attested). Verify with the GitHub CLI:

gh attestation verify accent-<version>-<target>.tar.gz --repo AccentCMS/accent

Editions and licensing

The binary is the same for everyone; a license key unlocks paid tiers at runtime. Keys are verified offline (Ed25519-signed) -- the binary never phones home.
