Our [Fair Use License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Community%20License%20EN.md) and our [PLANKA Pro/Enterprise License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Commercial%20License%20EN.md) are based on the [fair-code](http://faircode.io) model.
Educational institutions and non-profit organizations requiring commercial-level features or usage beyond our "Fair Use License" are encouraged to contact us for tailored licensing solutions and educational pricing. We look forward to helping your organization accomplish its mission!
PLANKA uses the [Fair Use License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Community%20License%20EN.md) and the [PLANKA Pro/Enterprise License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Commercial%20License%20EN.md). These licenses are based on the [fair-code](http://faircode.io) model.
### What source code is covered by the PLANKA's "Fair Use License"?
The [Fair Use License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Community%20License%20EN.md) applies to our source code hosted in our [main GitHub repository](https://github.com/plankanban/planka) except:
These exceptions are licensed under the [PLANKA Pro/Enterprise License](https://github.com/plankanban/planka/blob/master/LICENSES/PLANKA%20Commercial%20License%20EN.md).
The "Fair Use License" falls under the so-called [fair-code](http://faircode.io) licenses category. PLANKA's license is based on and extends the "Sustainable Use License" introduced by [n8n](https://n8n.io) who's advice was greatly appreciated. With similar goals in mind, we decided to follow their lead and adopt their model for our own needs. [Further below](#why-did-you-choose-this-license) you can read why we chose this license.
- You may use or modify PLANKA (a) for personal, hobby, or educational purposes, (b) internally within your own organization, (c) for private hosting for a typical number of friends, family, or personal projects, (d) to provide free access to non-profit organizations (as recognized by applicable tax authorities), or if you are a recognized non-profit organization yourself involving external users into your mission, and (e) public educational institutions for academic/research purposes only.
- Sharing accounts/credentials with third parties for business purposes or operating PLANKA as a hosted service for third parties for any commercial gain whatsoever is prohibited. Commercial gain includes any form of payment, advertising revenue, data monetization, or indirect commercial benefit or business advantage.
- You may not alter, remove, or obscure any licensing, copyright, or other notices from the software provided by the licensor. Any use of the licensor's trademarks is subject to applicable law.
Our license allows use for "internal business purposes", as well as for personal, hobby, educational, and limited private hosting scenarios. However, it prohibits using PLANKA for any form of commercial gain, such as selling a product or service where the value derives in any form from PLANKA's functionality, operating it as a paid hosted service, monetizing access or user data, or deriving other indirect commercial benefits.
- Providing consulting or public educational services related to PLANKA, for example, to build or integrate workflows for or in connection with PLANKA or develop custom modules to extend its functionalities.
If you use PLANKA and its backend services beyond internal operations within your own organization by enabling third-party access for commercial gain, such as sharing accounts with clients or selling a product or service where the value derives in any form from PLANKA's functionality, operating it as a paid hosted service, monetizing access or user data, or deriving other indirect commercial benefits, you are required to purchase a "PLANKA Pro/Enterprise License".
This includes scenarios where PLANKA serves as core infrastructure for third-party solutions, is accessed by users outside your legal entity as part of a paid or commercial offering, or where you sublicense, repackage, or otherwise make PLANKA available to external parties. Any arrangement that involves integrating PLANKA into another product to serve as the primary operational engine for that product also requires a valid "PLANKA Pro/Enterprise License" or proprietary license available for our enterprise customers.
### Can you give me some quick examples to clarify free use vs. enterprise use?
---
##### Example 1: Use PLANKA's API to control or respond to fabrication machinery processes
Use our API to show and control the feedback coming from fabrication steps inside your company or to control production line events by moving cards.
**ALLOWED** under the "Fair Use License". You can integrate PLANKA into your other systems to use its API to control your internal processes.
##### Example 2: Offer commercial consulting or support services
You provide a service to your client to help them implement new workflows and board concepts into the PLANKA setup.
**ALLOWED** under the "Fair Use License". You are free to offer commercial consulting or integration and support services for PLANKA without the need for a separate license agreement with us.
##### Example 3: Bundle PLANKA in a free and public Docker image
A school or charity bundles PLANKA in a free, public Docker image for students who want to use PLANKA to organize their fields of study.
**ALLOWED** under the "Fair Use License". Since PLANKA is given away for free and without commercial revenues in mind, you are more than welcome to allow charitable entities and schools better access to PLANKA.
**HOWEVER** if you also plan to provide students access to an otherwise school's internal PLANKA instance, this would require our "PLANKA Educational License", which we will gladly offer on request.
##### Example 4: Provide PLANKA logins to clients and affiliates
To facilitate better project feedback, you offer your client and someone from a joint venture, both of whom you have a commercial relationship with, access to project boards inside your company. They can now comment on cards and also benefit from PLANKA's real-time update capabilities.
**NOT ALLOWED** under the "Fair Use License". Offering PLANKA as part of a paid service to third parties or providing PLANKA access to third-party users outside your own legal entity in the context of a commercial relationship requires you to register a "PLANKA Pro/Enterprise License".
##### Example 5: Offer PLANKA as a hosted product to other companies
You want to earn money by providing PLANKA to companies, freelancers, and other people. This way they have easy access to project management and control from everywhere.
**NOT ALLOWED** under the "Fair Use License". Selling PLANKA-based services requires you to agree to a "PLANKA Reseller License". We have a special hosting agreement for those who want to provide paid PLANKA service to customers or simply act as resellers for our own "PLANKA Corporate Hosting Services".
- Personal, educational, hobby, or internal business use:
Free to use. You can use, modify, and host PLANKA for yourself, your team, or your organization for personal, educational, or internal operational purposes.
- Use by non-profits and public educational institutions:
Free to use for academic or research purposes, provided the organization qualifies as a non-profit under applicable tax laws. No application or special license is required.
- Providing access to third parties for any commercial gain:
Not allowed. Sharing accounts or credentials with third parties for any commercial gain is prohibited under the license, even if you are not directly charging for access.
- Hosting PLANKA as a commercial service:
Not allowed. You may not offer PLANKA as a hosted service or integrate it into a paid product or service where the value substantially comes from PLANKA. This includes advertising revenue, data monetization, or indirect commercial benefit or business advantage.
To exceed the limits of the self-hosted Community version, you'll need a "PLANKA Pro/Enterprise License". Once you register with us, the "Fair Use License" restrictions are not only legally lifted, but you also gain access to the full enterprise feature set.
Alternatively, you can exceed these limits by subscribing to a hosted version - either Community or Pro/Enterprise. This allows, for example, providing accounts for your customers.
If you want to provide PLANKA as a service for other organizations or integrate PLANKA into your own software, you must sign a separate revenue agreement with us. We actively encourage software integrators and technical staff to integrate and connect PLANKA within their other products and use our extensive API to respond to, control, and master processes within their company; we just ask them to sign an agreement laying out the terms of use and the license fees required by PLANKA for using the product. Through PLANKA's API, it is capable of controlling and responding to external systems. You can learn more [here](https://docs.planka.cloud/docs/category/api-reference/) or contact us about it.
If you are unsure whether the use case you have in mind constitutes an internal business purpose or not, take a look at the [examples above](#can-you-give-me-some-quick-examples-to-clarify-free-use-vs-enterprise-use), and if you're still not sure, please contact us at [license@planka.group](mailto:license@planka.group).
### Why isn't there a commercial license for a self-hosted Community version which lifts the "Fair Use License" limits?
We support the self-hosted Community version through our GitHub and Discord community channels, but we can't efficiently provide direct phone or email support for multiple versions while meeting our obligations to paying customers. That's why direct support is reserved exclusively for Pro/Enterprise customers.
However, we do offer professional installation services and monthly-based service contracts for setting up, updating, and monitoring all versions to help organizations get the most out of their PLANKA deployment - please contact us at [license@planka.group](mailto:license@planka.group).
### Why doesn't PLANKA use a default open-source license?
We spend a lot of time creating an easy yet powerful tool that makes controlling and mastering projects a fun experience. Also, we wanted PLANKA to be as widely and freely available as possible while also ensuring that we can build a sustainable and viable business. By making our product free to use, easy to distribute, and source-available, we help everyone access the product. By operating as a business, we can develop and release new features, fix bugs, and provide reliable software at scale long-term.
We believe that the "Fair Use License" is beneficial for the community as well as for the developers. Development is a costly enterprise, and giving away a Community version for free is a risk that many companies don't survive without selling software or the company. Therefore, many open-source companies live from donations or financial investors. Instead of selling our soul, we sell services and software licenses. This way we continue to grow, code, and support our community. So the short answer is "Live and let live" is how we feel about PLANKA.
Therefore, we are helping to promote [fair-code](https://faircode.io) software with the goal of making it a well-known umbrella term to describe software models like ours. To keep any friction around our proprietary license to an absolute minimum, we focus on two things:
1. Plain language, minimal length - the license is written in clear, concise English (a German version exists as well), with only the clauses absolutely needed.
2. Advocating fair-code - we actively promote the fair-code model so people recognize it as a straightforward, sustainable way to share and improve software like PLANKA.
### My company has a policy against using code that restricts commercial use - can I still use PLANKA?
Provided you are using PLANKA for internal business purposes and not making PLANKA available to your customers or affiliates, then of course you should be able to use PLANKA. If you are unsure whether the use case you have in mind constitutes an internal business purpose or not, take a look at the [examples above](#can-you-give-me-some-quick-examples-to-clarify-free-use-vs-enterprise-use), and if you're still unclear, email us at [license@planka.group](mailto:license@planka.group).
### What happens to code I contribute to PLANKA in regard to its "Fair Use License"?
Any code you contribute on GitHub is subject to GitHub's [terms of use](https://docs.github.com/en/site-policy/github-terms/github-terms-of-service#d_user_generated_content). In simple terms, this means you own and are responsible for anything you contribute, but that you grant other GitHub users certain rights to use this code. When you contribute code to a repository containing notice of a license, you license the code under the same terms.
PLANKA asks every contributor to sign our [Contributor License Agreement](https://github.com/plankanban/planka/blob/master/CONTRIBUTOR_LICENSE_AGREEMENT.md). In addition to the above, this gives PLANKA the ability to change its license without seeking additional permission. It also means you aren't liable for your contributions (e.g., in case they cause damage to someone else's business).
It's easy to get started contributing code to PLANKA on [GitHub](https://github.com/plankanban), and we've listed broader ways of participating in our community [here](https://github.com/plankanban/planka/blob/master/CONTRIBUTING.md).
### Is PLANKA open source?
PLANKA's source code is freely available under the "Fair Use License". While this doesn't align with the Open Source Initiative's strict definition (which doesn't allow any use limitations), PLANKA still offers nearly all the same benefits as traditionally open-source software to most users, including corporations.
We embrace what's often called the 'fair-code' model - our code is source-available and follows a simple "Live and let live" philosophy. This approach allows us to maintain a sustainable company while still providing transparency and flexibility to our community. Many companies are adopting this balanced licensing approach that preserves the spirit of openness while ensuring the project's long-term viability. We're proud to be part of this movement!
### What is fair-code, and how does the "Fair Use License" relate to it?
Fair-code is not a software license. It describes a software model where software:
- Is generally free to use and can be distributed by anyone.
- Has its source code openly available.
- Can be extended by anyone in public and private communities.
- Is commercially restricted by its authors.
The "Fair Use License" is a fair-code license. You can read more about it and see other examples of fair-code licenses [here](https://faircode.io). To get in touch with us about license questions, please email [license@planka.group](mailto:license@planka.group).
### Can I use the "Fair Use License" for my own project?
Yes! We ourselves made use of the "Fair Use License" by following others' footsteps who openly invite others on their website and in their license to follow the fair code path. Like them, we're excited to see more software use the "Fair Use License".
