GeckoFlag and Redmine are both self-hosted issue (ticket) tracking and project management tools that you install on your own server. But they differ in what kind of server they run on, how much work setup and maintenance take, and how you think about cost. This page is for teams considering a Redmine alternative: it compares the two tools on setup, cost, and features, and sums up which kind of team each one suits best.

First: Redmine Is an Excellent Tool
We want to say this up front: Redmine is an excellent open-source project management tool that has been used around the world for many years. It is free to use, includes a wiki, forums, time tracking, and version control integration out of the box, and has plenty of plugins for extending it.
This page is not meant to criticize Redmine. It is here to help you consider GeckoFlag as an option with a different approach to setup and operations.
The Short Answer: Who Each Tool Is For
GeckoFlag
For teams that want simple issue tracking on their own shared hosting with no monthly fees, and for agencies and freelancers who want to run it under their own brand for each client.
Redmine
For teams that want zero license costs, can build and maintain a Ruby on Rails server themselves, and want to extend features with plugins.

Ease of Setup and Maintenance
The biggest difference between the two tools is what they run on and how you install them.
Redmine can be installed on your own server, but because it runs on Ruby on Rails, it's hard to run on typical PHP-oriented shared hosting. The usual approach is to prepare a VPS and build the environment from the command line.
GeckoFlag runs on many shared hosting plans that support PHP and MySQL/MariaDB. Dependencies are bundled, so Composer isn't needed: after uploading the files, you simply follow the browser-based installer. Backups and updates are also handled from the admin panel. For step-by-step instructions, see Installation and the Namecheap hosting example.
Cost: One-Time Purchase vs. Free Open Source
- GeckoFlag: A one-time purchase of $30, with future updates included for free. There are no per-user fees. The only other cost is the server you install it on (one license covers one domain).
- Redmine: The software itself is free (GPL v2), and there are no per-user fees. On license cost alone, Redmine is the cheaper option.
What You Still Need When the Software Is Free
- A server: you need an environment that can run Ruby, such as a VPS.
- Setup: someone has to install and configure it from the command line.
- Maintenance: your team has to keep handling version upgrades, security fixes, and backups.
If you already have a PHP-oriented shared hosting plan, GeckoFlag can be installed right there.
Feature Differences
In terms of sheer number of features, Redmine, with its long history, comes out ahead. It includes a wiki, forums, time tracking, and integration with version control systems such as Git and Subversion out of the box, is available in 49 languages, and can be extended with plenty of plugins and themes. A Kanban board, on the other hand, is not built in and is added through plugins.
GeckoFlag keeps things simple and focused on what issue tracking needs. Issues can have a title, issue type, status, priority, assignee, start and due dates and more, and parent/child issues, a Kanban board, a Gantt chart, a wiki and file sharing are all built in. Statuses and priorities can be customized freely from the admin panel, and GeckoFlag also offers custom branding to change the site name and logo, as well as support for 15 languages that each user can switch between.
When GeckoFlag Isn't the Right Fit
- You want zero license costs: Redmine is free to use.
- Time tracking, forums, version control integration, or extending features with plugins is a must: Redmine will suit you better.
- You don't want to manage a server at all (you need a cloud version): GeckoFlag is only available as a self-hosted product.
Frequently Asked Questions
Can GeckoFlag replace Redmine?
For core project management such as creating issues, tracking statuses, parent/child issues, Kanban boards, Gantt charts, and a wiki, GeckoFlag can serve as a Redmine alternative. However, if you need time tracking, forums, version control integration, or plugin-based extensions, Redmine is the better fit.
What is the main difference from Redmine?
Both are self-hosted tools you install on your own server, but Redmine runs on Ruby on Rails while GeckoFlag runs on PHP and MySQL/MariaDB. That means GeckoFlag can be installed on many common shared hosting plans and set up through a browser-based installer.
Redmine is free, so why choose GeckoFlag?
Redmine itself is free, but your team has to set up the Ruby environment, upgrade versions, and handle security. GeckoFlag is a one-time purchase of $30, installs through the browser on shared hosting that supports PHP, and lets you run updates and backups from the admin panel. It is an option when you want to spend less effort on setup and maintenance.
Can I migrate data from Redmine to GeckoFlag?
There is no dedicated migration tool for Redmine. GeckoFlag has a CSV import feature for projects and issues, so if you reshape the data exported from Redmine to match GeckoFlag's CSV format, you can import the issues as new records. Rows that refer to statuses, priorities, or assignees that are not yet registered are skipped, so register them in GeckoFlag beforehand.
Can I try it before buying?
Yes. GeckoFlag has a demo site where you can check the screens and how it feels before you buy.
