AGPL licences in companies: risks and safe use

The open source misunderstanding: why free code does not mean free of legal obligations

Many managing directors and IT leads in the German Mittelstand wrongly assume that software on platforms such as GitHub may be used commercially without restrictions or legal obligations. The term open source is often equated with complete freedom. That, however, is a consequential error that carries considerable risks for your company. Every software project that is publicly accessible is subject to specific licence terms. If these are disregarded, warning letters as well as claims for injunctive relief and damages threaten, and in the worst case the forced shutdown of the affected application. That is why handling such technologies with legal certainty is a must for every decision maker, and systematic protection belongs on your agenda for IT security as a boardroom issue. This article is a professional assessment and not legal advice.

The apparent lack of cost often tempts developers to integrate third-party code into company applications without review. As soon as an open source program such as the popular analysis tool World Monitor is embedded in your own infrastructure, the legal bonds of the underlying licence take effect. In the case of World Monitor this is AGPL-3.0-only, a licence with strong copyleft. If you integrate this code into your own platform, under certain conditions the licence requires you to disclose the entire modified source code of your own software.

• The obligation to offer the corresponding source code if a modified version is provided as a service over a network.
• Retaining all copyright notices and licence texts in the source code.
• Complying with the strict copyleft principle, which means derived works must likewise be published under the same free licence^[1].
• The prohibition on introducing additional restrictions that take away the rights guaranteed to users.

For mid-sized companies this means a fine balance between innovation and legal certainty. Without structured oversight and complete IT documentation of the software components you use, you risk unintentional licence violations. This is exactly where modern service providers help with holistic managed IT or automated audits, in order to eliminate such risks from the outset.

What is the AGPL licence? The strictest form of copyleft in detail

The GNU Affero General Public License (AGPL-3.0) is one of the most restrictive open source licences in the world. While the GPL only triggers the source code obligation when the software is passed on, Section 13 of the AGPL closes the so-called SaaS gap. As soon as you or your development team modify an AGPL-licensed application and make it available to other users over a network, the strict copyleft obligation applies^[1]. This means: you must offer all users who access this application over a network (such as the internet or a company network) the complete corresponding source code of the modified version at no additional cost. The licence does not require publication to the general public. This therefore also applies to internal adaptations that are hosted as a cloud service.

• Obligation to offer source code: anyone who operates a modified version of the software over a network must offer all users of that service the complete corresponding source code of that version^[1].
• Passing on under the same licence: all changes and extensions to the software must remain licensed under the same AGPL-3.0 licence.
• Retention of all copyright notices: copyright and disclaimer notices in the code may neither be changed nor removed.
• Reach of the copyleft: if you embed AGPL code in your own software, the resulting overall work can itself fall under the AGPL and trigger the obligation to offer source code.

For IT leads and CTOs in mid-sized companies this carries massive business risks. If your company unnoticed integrates an AGPL-licensed tool into its own customer platform, you risk warning letters as well as claims for injunctive relief and damages. The practical consequence is then to offer the corresponding source code in a licence-compliant way or to stop using it. Well-founded IT governance and complete compliance are therefore not a mere formality but the only way to protect your intellectual property. A clear and automated record of all software dependencies used within your IT infrastructure helps here.

The SaaS loophole and how AGPL-3.0 governs network use

Classic open source licences such as the GNU General Public License (GPL) historically only take effect once software is passed on to third parties, physically or digitally. If you only use code internally on your own servers, you need not fear any disclosure. In the age of cloud computing and software as a service (SaaS), however, this led to a legal grey area, the so-called application service provider (ASP) or SaaS loophole. Large platforms were able to modify open source software and offer it to their customers over the network without ever having to disclose their own adaptations.

This is exactly where the GNU Affero General Public License (AGPL-3.0) comes in, the licence that also covers the popular repository World Monitor. It consistently closes this loophole via an extended clause for network use. The AGPL does not classify network use as distribution, but places a separate obligation alongside it in Section 13. As soon as customers, partners or the public access a version you have modified, or an interface based on it, over a network, you have to offer exactly those users the complete corresponding source code of the modified version at no additional cost.

• Direct access: external users open the user interface or the dashboard of the modified software in a browser.
• Interface use: a partner company queries data via an API that is based on the AGPL code.
• Source code offer: the complete corresponding source code of the modified application must be offered to the users of the service under the same licence.
• Separate licence: anyone who wants to avoid the disclosure obligation needs a separate licence from the rights holder, provided that one is offered.

For IT leads in mid-sized companies, the careless integration of such components carries enormous risks that can extend to warning letters as well as claims for injunctive relief and damages. Monitoring software licences is therefore part of solid risk management and shows once more why IT security has to be established as a boardroom issue in a modern company. Only continuous review protects you against legal pitfalls when using open source.

Practical example World Monitor: impressive features under strict conditions

The open source project World Monitor impressively demonstrates the potential of modern, freely accessible software. Initiated on 8 January 2026 by Elie Habib and actively maintained ever since, the repository koala73/worldmonitor on GitHub enjoys great popularity: around 67,900 stars and around 10,400 forks, as of 22 July 2026. For IT leads in your company, the application offers highly developed tools for global situational analysis. But the seemingly free use carries legal obligations that must be observed as part of professional managed IT.

Via the hosted demo at worldmonitor.app^[2] you can try out the enormous depth of functionality directly. The tool aggregates real-time data from more than 65 external data providers and presents it in a modern interface. The software bundles sophisticated features that are highly relevant for strategic decisions in mid-sized companies:

• More than 500 curated news sources in 15 categories plus a financial radar with 29 exchanges, commodities and crypto.
• An interactive 3D globe and a WebGL flat map with a total of 56 map layers for detailed visualisation.
• The Country Instability Index (CII) for 31 countries for the precise assessment of geographic and political risks.
• Local AI evaluation via Ollama without an external API key plus native desktop apps on Tauri 2 for macOS, Windows and Linux in 25 languages.

Behind this technological strength, however, there is a legal hurdle: World Monitor is published under the AGPL-3.0-only licence^[2]. Commercial use and self-hosting are in principle permitted, but only in strict compliance with the copyleft and source disclosure obligations. As soon as a modified version is operated over a network, the licence requires the corresponding source code to be offered to all users of that service. If you want to use the tool proprietarily without disclosing your own code, or to claim official trademark rights, the author expressly offers a separate commercial licence. Without a clean separation you risk serious licence violations that endanger your overall compliance.

The legal and financial consequences of AGPL licence violations

Anyone who ignores the strict provisions of AGPLv3 takes on considerable legal risks. As soon as your company breaches the licence terms, the right to use the software ends automatically. Section 8 of the AGPL does however provide for a cure: if you stop the violation, the licence provisionally revives; it is permanently reinstated if you remedy the breach within 30 days of a first notice from the rights holder, or if the rights holder does not get in touch within 60 days after the violation has ceased. Until then you are using the software without a licence. The rights holder can issue a warning letter, demand a cease and desist declaration with a contractual penalty and assert claims for injunctive relief and damages, in urgent cases also by way of an interim injunction. There is no statutory fine provision for licence violations; this is a copyright infringement. This account is a professional assessment and not legal advice.

Disclosure of trade secrets as the greatest risk

The most threatening scenario for your company, however, is the forced disclosure of your own source code. If you link proprietary software with AGPL code such as that of the World Monitor project by Elie Habib and provide it over a network, the source disclosure obligation applies. You then face the choice of offering the corresponding source code of your solution to the users of the service in a licence-compliant way, or shutting the service down. A court cannot force you to publish your code, but it can prohibit further use and award damages. For you as a managing director or IT lead, this risk is incalculable.

• Automatic end of the usage rights to the affected open source software, with the possibility of cure under Section 8 of the AGPL.
• Chargeable warning letters and lengthy court injunction proceedings brought by the developers.
• The choice between a licence-compliant source code offer and shutting down the affected service.
• Financial losses through the forced shutdown of business-critical systems and possible claims for damages.

To prevent such scenarios, clear IT governance and complete compliance are needed. Breaches of licence rights also affect your personal liability as a managing director, since compliance with legal and contractual requirements is part of the indispensable duty of care. Only if you systematically steer the licensing of open source components such as World Monitor from the outset do you protect your company against existential legal consequences.

Best practices for the legally secure use of open source in SMEs

To systematically minimise risks from copyleft effects and licence infringements in mid-sized companies, proactive software management is indispensable. Software such as the geopolitical dashboard World Monitor^[2] clearly shows that the careless use of AGPL code triggers far-reaching obligations. As a managing director or IT lead you must not leave control of the software supply chain to chance, especially since legal missteps can also touch on the subject of personal liability. With structured processes and technical support, however, the integration of open source software can be made entirely secure in legal terms.

• Creating a software register (SBOM): record all open source components in use and their licence types in your company without gaps, in order to guarantee the ability to provide information and compliance at any time.
• Automated licence scans: integrate automated tools directly into your development pipelines that check new code for risky licences such as AGPL-3.0-only before it flows into productive systems.
• Binding guidelines: define clear rules for your development team on which open source licences may be used without approval (for example MIT, Apache 2.0) and for which licences a legal review is necessary.
• Check commercial licensing: for business-critical applications without source code disclosure, use the commercial licence options offered by the authors, as they are also offered for World Monitor^[2].
