Your System

Choose Your Platform

Pick the platform you are installing on from the sections below.

See All Platforms

macOS

Install with Homebrew. Requires Apple Silicon and macOS 14 or newer.

brew tap leynier/tap && brew install --cask alera

The cask clears the quarantine attribute after installing, because the macOS build is not notarized yet. Or unpack alera-0.52.0-macos.tar.gz and move Alera.app to your Applications folder.

Download for macOS All Releases

Windows

Install with Scoop, which needs no administrator rights.

scoop bucket add leynier https://github.com/leynier/scoop-bucket
scoop install leynier/alera

Or with Chocolatey, from an elevated prompt.

choco install alera

Requires 64-bit Windows. Or unpack alera-0.52.0-windows.tar.gz anywhere and run Alera.exe.

Linux

Alera installs from a signed package repository so system dependencies resolve through apt or dnf. The same command installs and updates.

curl -fsSL https://alera.build/install.sh | sh

Requires x86_64 and Ubuntu 24.04 or newer, Debian 13 or newer, or Fedora. On RHEL, Rocky, and AlmaLinux enable RPM Fusion first, which is where mpv-libs comes from. openSUSE is not supported yet: the published RPM declares Fedora package names that openSUSE provides under different names.

Android

The companion app pairs with a running desktop workbench over your own network; it is not a standalone editor. Mobile ships on its own version sequence, so its releases carry a -mobile tag suffix. This is the universal alera-0.20.0-android.apk; per-architecture APKs are on the release page.

Download the APK All Mobile Releases

Sideloading an APK means Android asks you to allow installs from your browser or file manager. There is no Play Store listing yet.

iOS

Coming Soon

There is no iOS build to install yet. The companion app targets Android today; iOS is planned and has no date.

Manual Linux Setup

To add the repository yourself instead of running the script, import the signing key from https://updates.alera.build/linux/alera-archive-keyring.asc and confirm its fingerprint is5DE97E7CFE234A1C5869EC54708DA940734CF23A, then write one of these files.

/etc/apt/sources.list.d/alera.sources

Types: deb
URIs: https://updates.alera.build/linux/apt
Suites: stable
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/alera-archive-keyring.asc

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-alera

The published packages carry no per-package signature yet, sogpgcheck stays off whilerepo_gpgcheck verifies the signed repository metadata, which commits to the checksum of every package. That is the same chain apt relies on.

Code Signing Policy

Free code signing provided by SignPath.io, certificate by SignPath Foundation.

SignPath.io runs the signing service, and the SignPath Foundation issues the certificate to open source projects at no cost.

Alera is maintained by one person, who fills every role: Leynier Gutiérrez González is the sole committer, reviewer, and approver of signing requests.

Data handling is described in the Privacy Policy. Alera is local-first: your projects, terminals, and settings stay on your machine.

Current status, so you know what to expect from your system: Linux packages are distributed through a repository whose metadata is signed with the key above. Windows and macOS builds are not signed yet, so Windows SmartScreen reports an unknown publisher and macOS Gatekeeper asks you to allow the app explicitly. Windows signing through SignPath begins once the certificate is issued.
