What Gibbon is
Gibbon is a free school platform for learning, teaching, and school management, designed by educators. Teachers, students, parents, and administrators use a shared web-based system with configurable access. Its Planner handles lesson plans, homework submissions, curriculum mapping, and peer assessment. Student Profiles bring together academic, behavioural, medical, and special educational needs alerts for authorised users. Markbook, rubrics, tracking, and formal assessment modules support recording and reviewing student progress. Messenger lets users send group messages by email, SMS, or Message Wall. Schools can add modules and themes, including BigBlueButton and Moodle integration; documentation describes Google single sign-on and calendar integration, as well as Microsoft single sign-on setup. Gibbon is installed on a web server and schools manage their own hosting. The v30 download page lists PHP 8.0 and MySQL 8.0 minimums. Documentation and community forums are available, along with optional expert support by the hour or contract. Gibbon is used by international, public, home, and refugee schools. Its free plan includes attendance tracking, a gradebook, a parent portal, fee management, and admissions and enrollment; transport management is not included.

Getting started

- Prepare a web server meeting the v30 minimums of PHP 8.0 and MySQL 8.0.

Overview
Gibbon is a school information and learning platform built around the work of educators. It is a strong fit for schools seeking a shared space for classroom activity, student records, and administration, especially those able to run their own web server. Its breadth is appealing, but self-hosting makes technical upkeep part of the decision.
Key features
Teachers, students, parents, and administrators can use the same web-based platform, with access levels configured for different roles. That shared approach can reduce the need to split routine school work across separate systems; it also calls for careful permissions because profiles may include medical and special educational needs information.
Teaching and assessment
The Planner supports lesson plans, homework submissions, curriculum mapping, and peer assessment. Markbook, rubrics, tracking, and formal assessment modules help staff record and review progress. Schools wanting connected teaching workflows will get more scope than a gradebook alone provides, though a school seeking only one narrow classroom tool may not need this wider platform.
Records and communication
Student Profiles bring academic, behavioural, medical, and special educational needs alerts together for authorised users. Messenger can send email, SMS, and Message Wall messages to groups drawn from the system. The combination supports coordinated record-keeping and communication, with access control especially important for sensitive student data.
Integrations and extensions
Gibbon documentation covers Google single sign-on and calendar integration, as well as Microsoft single sign-on setup. Schools can extend the platform with modules and themes; examples include BigBlueButton and Moodle integration. This flexibility is useful for schools willing to configure their system, but it also means the right setup may require more administration than a fixed, hosted service.
Pricing
Gibbon Core: free. The free, open-source platform includes no software charge, but hosting is self-managed. That makes it a practical option for schools that can provide server administration; the apparent price advantage is less decisive if the school cannot take on hosting and upkeep.
Gibbon offers documentation and community forums, with optional expert help through ad hoc support or a support contract. The v30 download page states minimum requirements of PHP 8.0 and MySQL 8.0. Older versions are not directly supported, and schools are advised to use the current stable version in production, so maintaining a current installation matters.
Platforms
Gibbon is web-based and self-hosted, with platform availability for Linux, macOS, and Windows. Schools install it on a web server, either on their own infrastructure or through hosting they manage. Its deployment model is not a fit for buyers who want software hosting handled entirely by the provider.
Who it's for
Gibbon says it is used by international, public, home, and refugee schools. Its shared access, teaching tools, student records, and administrative workflows make it relevant to schools looking to bring several functions into one system. It suits organizations with the capacity to manage a server and configure role-based access better than schools wanting a fully managed service with minimal technical responsibility.
Pros and cons
- Pros: A free, open-source core avoids a software licence charge, while the Planner, assessment tools, student profiles, and messaging cover a broad range of school workflows.
- Pros: Configurable access levels and extensible modules let schools shape a shared platform around different roles and needs.
- Cons: Hosting is self-managed, so schools must take responsibility for installation and ongoing maintenance.
- Cons: Older releases are not directly supported; production use calls for keeping to the current stable version.
- Cons: Student profiles can include sensitive information, making careful access configuration essential.
Alternatives
For another self-hosted option, RosarioSIS also has a free plan and requires the school to manage updates; it may suit schools comparing free systems that run on PHP and a SQL database.
openSIS offers a free, open-source Community Edition that schools install and manage independently, making it another option for those comfortable with self-managed software.
OpenEMIS Admissions is free open-source software with no licensing fees; consider it when admissions is the relevant focus.
Gradelink is a paid alternative for readers comparing school software with a different pricing model.
Aeries SIS, Ed-admin, Fedena, and Infinite Campus are other alternatives to compare.

Verdict
Choose Gibbon if your school wants a broad, shared platform for teaching, records, assessment, and communication without paying a software licence fee, and can manage its own hosting. Look elsewhere if you need a provider-managed service or cannot commit to maintaining a current installation and controlling access to sensitive student records.
Verdict
Gibbon brings school management and learning tools into a shared platform, with a free plan and extensible modules. Schools should be prepared to host it themselves and use a current stable version in production.
