Digital voting platforms are becoming increasingly important for organizations that need to make transparent and reliable decisions. Associations, universities, unions, and committees are moving away from manual voting processes and adopting tools that support secure online participation.
Through our work with online voting systems, we have supported more than 1,000 organizations across 35 countries in running digital elections and governance votes. This experience provides valuable insights into how different voting platforms perform in real-world environments.
In this article, we compare OpenSlides and NemoVote, two platforms that enable organizations to conduct online voting. While both solutions support digital decision-making, they are designed for different governance workflows and organizational needs.

Online voting tools often serve different organizational needs. Some platforms are designed to manage entire meetings and conferences, while others focus on secure and flexible voting processes.
Understanding these differences helps organizations choose the right solution for their governance structure.
OpenSlides is a German meeting and conference management platform with integrated online voting functionality.
The platform allows organizations to digitally manage assemblies, meetings, and committee processes.
Core features include:
The platform supports several voting options, including:
OpenSlides can be used for in-person, hybrid, and virtual meetings, enabling organizations to run assemblies regardless of location.
Because the platform combines meeting management with voting, OpenSlides is particularly suited for organizations that run structured assemblies with agendas, motions, and debates.
NemoVote is a digital governance and online voting platform developed and hosted in Germany, designed for secure and GDPR-compliant elections.
The platform is designed to support organizations conducting both simple votes and complex governance elections.
NemoVote is used by a wide range of organizations, including:
The platform combines enterprise-grade security with a simple and intuitive interface, allowing organizations to run elections without requiring technical expertise.
Key governance capabilities include:
The system is fully browser-based, allowing participants to vote from desktop, tablet, or mobile devices.
User experience plays an important role in online elections, especially when administrators and voters may only interact with the system occasionally.
OpenSlides provides a large set of governance tools designed for managing meetings and assemblies.
Administrators can manage many aspects of a meeting within the platform, including:
These tools make OpenSlides powerful for conference-style governance processes.
However, because many modules are integrated into the same system, administrators may need to configure several elements before running elections or meetings.
NemoVote is designed around the idea that secure elections should be easy to run.
The platform guides administrators through the election setup process using a structured interface and clear workflows.
Key usability advantages include:
Because of this guided setup process, organizations can run elections without requiring specialized technical knowledge.
Security and compliance are critical factors when selecting an online voting platform.
OpenSlides includes several security and data protection measures designed to support compliant digital meetings and elections.
OpenSlides instances are hosted in certified data centres in Germany, which are compliant with ISO 27001 security standards and operate within the requirements of the General Data Protection Regulation (GDPR).
The platform also implements secure infrastructure and data protection measures such as:
The platform also supports anonymous or secret voting procedures, and the contractor is obligated to ensure that ballot secrecy is maintained during the voting process. However, due to its open-source and self-hosted nature, the level of anonymity can depend on the specific server setup and implementation, which may raise concerns if not properly configured.
NemoVote was designed specifically for environments where security, transparency, and compliance are essential.
Security measures described in NemoVote include:
Dedicated containers and separate databases
Each customer operates within a logically isolated environment, ensuring that organizational data remains protected.
Different organizations require different governance structures. Some platforms are optimized for formal assemblies, while others focus on flexible voting across multiple decision scenarios.
OpenSlides is particularly well suited for organizations running formal assemblies and conferences.
Typical use cases include:
Features such as motion debates, agenda management, and speaker lists allow organizations to manage the full structure of large meetings.
NemoVote focuses on enabling digital decision-making across many types of organizations.
The platform supports voting processes for:
Because the system is designed for both simple votes and complex elections, organizations can adapt it to different governance scenarios without additional technical setup.
Pricing structures can vary significantly between governance platforms.
Different modules are available depending on the organizational needs.
For the online voting module, pricing depends on the number of accounts and hosting duration:
OpenSlides pricing examples (online voting)
| Number of accounts | 14 days | 1 month |
| 100 accounts | € 200 | € 400 |
| 500 accounts | € 1,000 | € 2,000 |
| 1,000 accounts | € 2,000 | € 4,000 |
OpenSlides also offers additional modules for meeting management:
Conference Management
Committee Management
The platform also offers an open-source version, allowing organizations to self-host the software if they prefer to manage the infrastructure themselves.
NemoVote provides clear and transparent pricing with flexible models designed for both one-time elections and ongoing use.
These include:
The subscription model is ideal for organizations that conduct elections regularly and need continuous access with predictable pricing.
Pricing starts at:
| 100 voters | €40.50 per month |
| 500 voters | €112.50 per month |
| 1,000 voters | €202.50 per month |
Features included:
This model is particularly suitable for organizations, committees, and teams with recurring voting needs.
For organizations that only need to run a single election, NemoVote offers a flexible event-based pricing option.
Pricing starts at:
| 100 voters | €129 per event |
| 500 voters | €369 per event |
| 1000 voters | €669 per event |
€50 for each additional day
Features include:
Because of this structure, organizations can choose between cost-efficient one-time elections or long-term subscription access, depending on their needs.
Looking at the pricing structures, OpenSlides relies on per-account pricing, which seems comparably higher at first. However, it is worth noting, that using the open-source technology, organisations are able to host OpenSlides at way lower cost themselves. However, this might interfere with the anonymity of ballots.
NemoVote, in contrast, offers transparent pricing with clear subscription and event-based options, making it easier to plan costs and choose a model that fits both one-time and recurring elections.
Both OpenSlides and NemoVote provide valuable capabilities, but they serve different governance needs.
OpenSlides may be a good choice if:
NemoVote may be better suited if:
Both OpenSlides and NemoVote support secure online voting and provide tools for organizations to conduct digital decision-making. OpenSlides combines voting with broader meeting and conference management features, such as agendas, motions, and speaker lists, which makes it particularly suitable for organizations that want to manage entire assemblies within one platform.
NemoVote, in contrast, focuses specifically on online elections and governance voting, with workflows designed to make elections easy to set up and run for administrators and participants. For organizations whose main goal is to conduct secure digital elections rather than manage full meeting processes, NemoVote can therefore offer a more streamlined solution.
In addition, NemoVote’s flexible pricing models can be more practical for organizations compared to account-based pricing structures.
As a result, organizations looking for a dedicated platform for online voting and elections switch to NemoVote as the more practical alternative.
