Open Source verpflichtet

Thoughtworks unterstützt und nutzt Open Source-Software, wo immer möglich


Softwareentwicklung liegt uns am Herzen. Wir nehmen unser Handwerk und unsere Rolle als Vordenker:innen ernst, mit dem Ziel, einen außergewöhnlichen Mehrwert zu schaffen und die IT-Branche zu revolutionieren. Dies ist ein zentraler Grundsatz, verankert in unserer DNA.


Wir sind überzeugt, dass die Qualität von Software durch offene Kommunikation und Kollaboration positiv beeinflusst wird. Deshalb lieben wir Open Source, und das schon seit unserer Gründung. Die Entwicklung von Open Source-Software ermöglicht es uns, unsere Erfahrungen weiterzugeben, neue Arbeitsweisen auszutauschen und von der breiten Gemeinschaft zu lernen.


Was wir entwickeln


Unsere Technolog:innen bringen erfolgreiche, praxiserprobte Techniken und Ideen aus der ganzen Welt in Open-Source-Lösungen ein. Hier finden Sie einige Highlights unserer Arbeit.

Continuous Delivery und Monitoring

Understanding your build pipeline and continually improving it isn't always easy. buildviz provides graphs detailing runtime behavior, failures and stability of a pipeline.

Your builds should always be green. As a build monitor with attitude, Nevergreen understands this. It only shows you projects that have failed or are building.

GoCD enables you to easily model and visualize complex workflows end to end, simplifying continuous delivery. It also supports modern infrastructure and cloud deployments.

Machine Learning

CD4ML — Scenarios is evolving to be a great starter kit for bringing machine learning projects into production; the project contains a sample application and machine learning code used for the Continuous Delivery for Machine Learning (CD4ML) and Continuous Intelligence workshop.

EmoPy is a deep neural net toolkit for facial expression analysis. It serves as an accessible educational tool and practical example of how to approach the problem of emotion classification via facial expression recognition (FER). EmoPy has generated interest with students, academics, robotic scientists and other tech consulting firms.


Isula is a Java library for the implementation of artificial intelligence algorithms based on the ant colony optimization paradigm. It contains the common elements present in the meta-heuristic to allow algorithm designers the reutilization of common behaviors. With Isula, solving optimization problems with Ant Colony can be done in a few lines of code.

Digital Identity

TWallet is the next-generation digital wallet. It supports general payment, digital currency transfer and duplex-offline payment. With an emphasis on personal privacy issues, it introduces technologies such as decentralized identity and verifiable claims.

Sicherheit und Datenschutz

By hooking into the pre-push hook provided by Git, Talisman validates the outgoing changeset for things that look suspicious — such as authorization tokens and private keys.

Hawkeye scanner-cli is a project security, vulnerability and general risk highlighting tool, which integrates into pre-commit hooks and pipelines.

FreedomBox is a community project to design, develop and promote personal servers running free software for private and personal communications. The project's goals are privacy, data ownership and censorship resistance under oppressive regimes.

Social Impact

Bahamas Marine Mammal Research Organization (BMMRO) is a non-profit scientific research organization led by scientists finding marine mammals in and around Abaco Island, Bahamas, understanding their primary areas of habitation and using what they learn to make a difference. As a part of the conservation of biodiversity efforts within the social impact umbrella, a team of Thoughtworkers in the UK are developing an open-source web application. The vision is to build a data centric tool to help researchers promote conservation of marine mammals.

Bahmni, an easy-to-use electronic medical record and hospital management system, combines and enhances multiple open-source products into a single solution (including integration with DHIS tracker which was built in collaboration with PSI Zimbabwe). The recent Bahmni COVID-19 Program adds COVID-19-specific features.


Project EKA is an endeavour to create reference solutions for exchanging health information with patients’ consent in Indian Healthcare context. The architecture and solutions are largely inspired by the proposed National Health Stack (NHS). The team wants to improve patient care through informed decision making, clinical history assessments, treatment management and ensuring continuity of care through this initiative.

EpiRust is an open-source fast agent-based simulation framework to model epidemics in large cities. Using this framework, researchers can model diseases like smallpox, H1N1, and now COVID-19. Researchers can use EpiRust to simulate a disease model for a city with a population of up to a few million people using commodity hardware like laptops and desktops.

OpenMRS is a platform used to create a customized EMR system in response to actual needs on the ground. It serves an essential role in a country’s health information system. Data from OpenMRS is increasingly used to inform the public health decisions needed to achieve the UN Sustainable Development Goals, measure progress towards UNAIDS’ 95-95-95 targets for HIV epidemic control and achieve universal health coverage.

Support for Research

HardPosit is a library of hardware units that implement Posit arithmetic using Chisel, a Scala embedded hardware description language. This project is maintained by a relatively small team at E4R (Engineering for Research). It deals with a different programming paradigm all together (hardware description/digital design) and introduces a less familiar technology to the community, ultimately opening doors for new endeavors.

CCMenu displays the build status of projects on a continuous integration server as an item in the Mac's menu bar.

Laconia is a small, lightweight framework for developing AWS Lambda functions in JavaScript.

CommandDotNet is a framework for building modern CLI apps in .NET Core. It has integrations with multiple libraries including autofac and fluent validation.

Batect makes it easy to define and share your development and testing tasks in terms of Docker containers and run those tasks quickly and consistently locally and on CI.

Dojo creates standard development environments, versioned and released as Docker images. The tool's goal is to encourage a better approach to managing development environments as code.


Arium is an automation testing framework for 3D applications built on Unity. The framework is simple, lightweight, and extendable

Taiko is a free and open source Node.js library with a simple API to automate Chromium-based browsers (Chrome, Microsoft Edge, Opera) and Firefox.

Mountebank is the first tool to provide cross-platform, multiprotocol test doubles over the wire.

Simply point your application under test to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.
