A Go CMS
One binary
Choose your platform, review the release, and get started.
Choose a prebuilt oCMS archive for your platform. Each archive includes the CMS binary, embedded admin assets, core themes and built-in modules, the README, and the license. Go and Node.js are not required to run a prebuilt binary.
Review the release details and upgrade requirements below, then use the platform-specific quick start to run oCMS locally. Keep your database, uploads, custom themes, and configuration when updating an existing site.
Read the latest release notes before installing or upgrading.
Browse the local release history for previous changes and upgrade context.
These links always download the latest stable release from GitHub. Choose the archive for your platform; all archives are .tar.gz files.
Download SHA-256 checksums. Verify the archive before extracting or running it. GitHub build-provenance attestations are also available for these archives.
The details below were checked for v0.30.0 on 2 November 2026. Download links above follow the latest stable release; use its release notes for current changes and requirements.
Read the v0.30.0 release notes.
Production requires two-factor authentication by default. Configure OCMS_MFA_KEY with at least 32 bytes, distinct from OCMS_SESSION_SECRET. Keep the MFA key stable and back it up with the database. Existing users enroll an authenticator at their next sign-in. Read the breaking changes before upgrading; server startup applies pending database migrations.
Follow the complete upgrade walkthrough to rehearse the release, back up the site, install the verified binary and recover the old installation if necessary.
Optionally verify an archive's build provenance with the GitHub CLI before extracting it. For the Linux AMD64 download:
gh attestation verify ocms-linux-amd64.tar.gz --repo olegiv/ocms-goPrefer to explore first? Try the live oCMS demo in your browser.
Explore the admin interface. Content editing is disabled in the shared demo; sample data resets daily. Open demo admin (opens in a new tab)
Choose your platform and run oCMS locally.

)Run in Bash or Zsh. The commands create a new directory and verify the archive before extracting it.
Open localhost:8080/admin/, then follow the first-run setup instructions before deployment.
Follow the Build your first site walkthrough to publish a page, customize a theme, and prepare for deployment.
Having trouble? Check installation troubleshooting.
These checks apply to the prebuilt quick start. Read the terminal's first error before running a command again.
First confirm that you downloaded the Apple Silicon archive from the release linked above and that its checksum matches. Try opening the binary once, then go to System Settings → Privacy & Security and use Open Anyway if macOS offers it.
See Apple's guidance on opening apps safely. If macOS reports malware or that an app will damage your computer, stop and investigate the download.
Stop the other service if you own it, or change OCMS_SERVER_PORT=8080 to OCMS_SERVER_PORT=8081 in my-site/.env. Restart oCMS from the generated site directory, then open localhost:8081/admin/.
Update OCMS_SERVER_PORT in your shell too if you already exported it: environment variables take precedence over the file.
Extract the archive into a directory owned by your user and run the quick start there. If the binary lost its executable permission during copying, run chmod u+x ./ocms from the extracted release directory.
Start the server from my-site with ../ocms serve. The user running oCMS needs write access to the site directory, the SQLite database and its containing directory, and uploads. Do not use chmod 777 or run the local quick start as root.
Download both the archive and checksums.txt again from the latest stable release, into a fresh directory. Choose the checksum command for your platform and rerun verification before extracting.
On macOS the quick start uses shasum -a 256 -c -; on Linux it uses sha256sum -c -. A mismatch means the archive is not ready to run. Do not bypass verification.
Check uname -m: Linux x86_64 uses AMD64; Linux aarch64 or arm64 uses ARM64; an Apple Silicon Mac uses the macOS ARM64 archive. Linux and macOS binaries are not interchangeable.
The prebuilt options above cover Linux AMD64, Linux ARM64 and Apple Silicon macOS. See the source build instructions on master for other build options.
