Gibbon is a free, open-source school platform for learning, teaching, and school administration.
What Gibbon is
Gibbon is a free, open-source school platform for learning, teaching, and school administration. Designed by educators, it gives teachers, students, parents, and administrators one web-based system while allowing schools to set different access levels. The Planner organizes lesson plans, homework submissions, curriculum mapping, and peer assessment. Student Profiles collect academic, behavioural, medical, and special educational needs alerts for authorised users. Markbook, rubrics, progress tracking, and formal assessment modules support recording and reviewing student achievement. Attendance tracking, gradebook, parent portal, fee management, and admissions and enrollment are available; transport management is not. Messenger sends group communications through email, SMS, or a Message Wall. Schools can extend the platform with modules and themes, including BigBlueButton and Moodle integration. Documentation covers Google single sign-on and calendar integration and Microsoft single sign-on setup. Gibbon is installed on a web server and hosted by the school, with minimum requirements of PHP 8.0 and MySQL 8.0 for the v30 download. Documentation, community forums, and optional expert support are available. Gibbon says it serves international, public, home, and refugee schools.

The full review of Gibbon
Gibbon is a free, open-source school platform that combines classroom planning, student records, assessment, communication, and administration in one web system. It suits schools with the technical capacity to run their own server and with several school roles needing shared, configurable access. The trade-off is that the software price is zero while hosting, updates, and operational responsibility stay with the school.
Overview
Designed by educators and founded in 2010 in Hong Kong, Gibbon is intended for international, public, home, and refugee schools. Teachers, students, parents, and administrators work in the same platform, with access levels adjustable by role. That unified approach can reduce the need to stitch together separate classroom and office tools, but it also puts schools in charge of sensible permissions for records that may include medical and special educational needs information.
Gibbon is self-hosted software installed on a web server, including a school's own server. The v30 download page requires at least PHP 8.0 and MySQL 8.0. Schools therefore need suitable server administration, backup, and update practices rather than expecting a vendor-managed service.
Key features
Teaching and assessment
The Planner covers lesson plans, homework submissions, curriculum mapping, and peer assessment. Markbook, rubrics, progress tracking, and formal assessment modules support both routine grading and more structured reviews. This breadth is useful for schools seeking connected teaching workflows; it is unnecessary overhead if the only requirement is a simple gradebook.
Student 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 posts to groups drawn from the system, making it practical for class, year, or wider-school communication. The same centralisation that saves duplicated data entry makes role configuration and ongoing account administration important.
Integrations and extensions
Documentation describes Google single sign-on and calendar integration, as well as Microsoft single sign-on setup. Schools can add modules and themes; listed extensions include BigBlueButton and Moodle integration. These options give a self-hosting school room to adapt the system, although each extension adds another component to manage.
Core administration
Gibbon includes attendance tracking, a gradebook, a parent portal, fee management, and admissions and enrollment. It does not provide transport management, so schools needing bus routes or transport operations will require another system or a different platform.
Pricing
Gibbon Core — free. This free, open-source school platform has no software charge, and hosting is self-managed. There are no paid tiers, seat allowances, trial period, or renewal terms stated for this plan. The saving is significant for schools able to supply and maintain the required web server; schools without that capability should budget for their own infrastructure and administration instead of treating the plan as a managed service.
Platforms
Gibbon runs on Linux, macOS, and Windows environments through the web, and it can be self-hosted. The stated server baseline for v30 is PHP 8.0 and MySQL 8.0. It is therefore a fit for schools able to operate a compatible web stack, not for organisations seeking a turnkey hosted deployment.
Who it's for
Choose Gibbon when a school wants one configurable system spanning teaching, records, assessment, messaging, attendance, fees, and enrollment, and has staff who can run a server. Its role-based access and parent-facing capabilities suit communities where teachers, families, students, and administrators need connected workflows. It is a weaker fit for schools that cannot maintain PHP and MySQL hosting, want vendor-managed operations, or require transport management within the same product.
Pros and cons
Pros
- No software fee: the core plan is free and open source, allowing schools to avoid licensing charges.
- Broad school coverage: planning, homework, curriculum mapping, assessment, attendance, fees, admissions, and parent access sit in one platform.
- Configurable shared access: distinct school roles can use the same web system, with permissions adjustable to the role.
- Extensible deployment: modules, themes, BigBlueButton, and Moodle integration provide ways to adapt the installation.
- Multiple support routes: documentation and community forums are available, with optional ad hoc expert support or a support contract.
Cons
- Self-hosting burden: the school must provide and maintain a web server meeting PHP 8.0 and MySQL 8.0 requirements.
- Security upkeep is essential: older Gibbon versions are not directly supported, and production use is advised on the current stable release.
- No transport management: bus and transport workflows are outside the platform's stated scope.
- Permission management matters: consolidated medical, behavioural, and special-needs data demands careful authorised access.

Verdict
Gibbon is a strong choice for schools that want wide school-management coverage without licensing fees and can confidently operate their own PHP/MySQL server. Its unified records, teaching, assessment, messaging, and administration tools are the main reason to choose it. Look elsewhere if self-hosting and version maintenance are unacceptable, or if transport management is a core requirement.
