How to Check OJS Version
Open Journal Systems normally publishes its software version in a generator meta tag in the HTML source. You can inspect the source manually, or use this checker to request the public page, follow the journal's redirect, and read the OJS version automatically.
The generator tag typically looks like this in the page source:
This checker reads that tag, extracts the version string, normalises it, and compares it with the current OJS LTS baseline. No JavaScript is executed from the remote site.
Paste the journal URL
Enter the full URL or just the domain. Redirects (e.g. domain to /index.php/journal) are followed automatically.
Secure server-side fetch
The CyberDairy server fetches the page. Private and internal IP addresses are blocked at every redirect hop.
Generator tag parsed
HTML is parsed with a DOM parser. The generator meta tag is found and the OJS version is extracted.
Version compared
The detected version is compared with the current OJS LTS baseline and the result is displayed with upgrade guidance if needed.
Why OJS Versions Matter
Keeping OJS current affects the security, compatibility, and publishing infrastructure of a journal. Here is why the version you are running matters.
Security & maintenance fixes
Supported releases receive patches for known issues. Older branches may not receive current fixes, leaving avoidable exposure.
PHP & database compatibility
Each OJS branch has PHP version requirements. Running OJS 3.2.x on PHP 8.x produces errors or breaks functionality.
Plugin & theme compatibility
Plugins and themes built for OJS 3.4+ may not work on 3.3.x or earlier. Older versions can block access to newer ecosystem tools.
Crossref & DOI integrations
DOI registration, Crossref deposits, and ORCID integrations are updated in newer OJS releases to match evolving API requirements.
Indexing & discoverability
OAI-PMH metadata, PKP Index compatibility, and structured metadata formats are improved in newer releases.
Future OJS development
PKP builds new features on current branches. Staying supported keeps a journal eligible for future improvements and community support.
What Is the OJS Latest Version?
CyberDairy currently uses OJS 3.5.0-5 LTS as the latest verified production baseline for this checker. The baseline is maintained centrally so the tool can be updated when PKP publishes a newer stable or LTS maintenance release.
The current OJS LTS baseline was released on June 30, 2026 and was verified by CyberDairy on September 13, 2026.

Frequently Asked Questions
Enter the public journal URL in the checker. The tool requests the page and looks for the Open Journal Systems generator meta tag, which normally includes the installed OJS version.
This checker currently uses OJS 3.5.0-5 LTS as the CyberDairy-verified baseline. The baseline is updated centrally whenever PKP releases a newer stable or LTS maintenance version.
The generator tag may have been removed, a firewall may be blocking the request, the URL may point to a non-OJS page, or an anti-bot page may be returned instead of the journal HTML.
No. Version age alone does not prove compromise. However, staying on supported releases helps ensure that current maintenance and security fixes are available and reduces avoidable compatibility and security risk.
Yes. The checker safely follows normal HTTP redirects, including a domain that redirects to an OJS path such as /index.php/journal. Every redirect destination is security-validated before it is requested.
