Useful software. Clear choices. A better way to find what you need.
QualCoder is a qualitative analysis application for coding text and supported media, organizing categories, and reviewing evidence. It provides a local research workspace for interpreting interviews, documents, images, audio, and video with explicit coding decisions.
Taguette is a qualitative research tool for importing documents, highlighting passages, and organizing them with tags. It provides a focused workflow for thematic coding and exporting coded material, with local or self-hosted operation available through its open-source software.
OpenSesame builds behavioral experiments through a graphical interface with scripting available for customization. It supports presenting stimuli and collecting responses, giving researchers a practical way to structure controlled tasks while checking timing and hardware behavior on their own setup.
PsychoPy creates behavioral and neuroscience experiments using a visual Builder interface or Python code. It supports stimulus presentation, response recording, and local experiment execution, while online hosting through associated services has separate access and usage arrangements.
eLabFTW is an electronic laboratory notebook for documenting experiments and managing research resources. Its self-hosted platform combines entries, attachments, templates, and team organization, helping laboratories keep experimental records in a searchable system under their administration.
DSpace is repository software for collecting, describing, and publishing digital research outputs and institutional materials. It supports organized collections, metadata, and access management, giving libraries and research institutions a platform for maintaining a self-hosted scholarly repository.
LibreCAD is a two-dimensional CAD application for creating technical drawings with layers, dimensions, and standard drafting tools. It serves users who need editable 2D geometry without a subscription, while remaining distinct from full parametric 3D modeling systems.
SolveSpace is a parametric CAD tool for constrained sketches, simple solid models, and mechanical assemblies. It offers a compact environment for dimension-driven design, helping users explore geometry and relationships without the overhead of a larger engineering suite.
OpenSCAD creates solid 3D models from scripts that describe geometry and transformations. It is particularly useful for dimension-driven parts and repeatable variants, offering a code-centered modeling workflow rather than a conventional interactive sculpting or drawing interface.
BRL-CAD is a solid-modeling system with geometry editing, ray tracing, and analysis tools. Its long-established constructive geometry workflow serves technical users who need explicit solid models and computational geometry capabilities rather than a purely artistic modeling interface.
KiCad is an electronic design suite for drawing schematics and laying out printed circuit boards. It includes electrical and design-rule checks, board visualization, and manufacturing outputs, supporting a complete PCB workflow without a software subscription or artificial board-size tier.
LibrePCB is an electronic design application for creating schematics and printed circuit boards. Its library and project workflows aim to keep component definitions and board design organized, making it useful for makers and engineers seeking an open desktop PCB tool.
QElectroTech creates electrical schematics and industrial diagrams using reusable symbols and drawing elements. It helps document wiring and control systems in an organized project, with a focus on schematic communication rather than numerical circuit simulation or PCB routing.
OpenModelica is a modeling and simulation environment based on the Modelica language. It supports equation-based descriptions of physical systems and reusable component models, helping engineers and researchers explore interactions across multiple domains in an open simulation toolchain.
OpenFOAM is a collection of open-source computational fluid dynamics tools for setting up, solving, and analyzing fluid-flow problems. It gives experienced users access to solver implementations and case configuration, with substantial responsibility for meshing, numerical choices, and validation.
Code_Aster is a finite-element simulation system for structural and multiphysics analysis, developed for demanding engineering studies. It offers a broad set of modeling and solution methods, with open-source access to the computational tools and their documented numerical behavior.
CalculiX is a finite-element analysis package for structural and related engineering simulations. It combines solver capabilities with a pre- and post-processing workflow, supporting users who can prepare meshes, define materials and boundary conditions, and interpret numerical results carefully.
Elmer FEM is a multiphysics finite-element package with solvers for several physical domains and tools for model setup. It supports researchers and engineers who need coupled simulations and can manage the mesh, material definitions, boundary conditions, and numerical validation.
