Useful software. Clear choices. A better way to find what you need.
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.
SU2 is an open-source suite for computational analysis and design optimization, particularly in aerodynamic and fluid-flow applications. Its configurable solvers and sensitivity tools support technical users who want to investigate performance and optimize geometry through reproducible numerical workflows.
OpenRocket designs and simulates model rockets using configurable components, motors, and flight conditions. It helps hobbyists compare stability and predicted trajectories before construction, while real-world material choices, assembly quality, weather, and flight rules remain separate considerations.
OpenVSP is a parametric geometry tool for aircraft concepts, using configurable components to build and modify vehicle shapes. It supports early design exploration and analysis preparation, helping users compare configurations before moving into more detailed engineering workflows.
EnergyPlus is a whole-building simulation engine for evaluating energy consumption and related thermal behavior. It models building systems and operating conditions through detailed inputs, supporting researchers and engineers who need reproducible analysis of design or operational alternatives.
BIMvision is an IFC model viewer for examining building models exported from different design systems. Its free core application supports visual inspection and model navigation without requiring the original authoring software, while optional plugins add separately licensed functions.
Penpot is a browser-based interface design platform that brings vector drawing, reusable components, responsive layouts and interactive prototypes into a shared workspace for designers and developers building digital products.
Pencil Project is a desktop mockup tool for arranging interface screens and diagrams with reusable shapes. It helps teams explain navigation and layout decisions before committing to detailed visual design.
MyPaint is a focused digital painting application with an expansive canvas and a configurable brush system. It suits sketching and expressive illustration where tablet response and uncluttered drawing matter most.
Pinta combines familiar painting tools with selections, adjustments and image effects in a compact desktop editor. It is useful for everyday image cleanup, annotated graphics and simple illustrations across major desktop systems.
Photopea is a browser image editor for layered raster and vector work. Its familiar editing model helps users open complex design files, retouch photographs and prepare graphics without installing desktop software.
darktable is a raw photography editor and library manager with a non-destructive processing pipeline. It gives photographers detailed control over tone, color and image organization while retaining their original camera files.
RawTherapee develops camera raw files with extensive controls for color, detail and image reconstruction. Its desktop workflow suits photographers who want fine adjustment and repeatable processing without altering original image data.
digiKam organizes photo and video collections with albums, searchable metadata, face tagging and editing tools. It is suited to people who need to find and maintain a growing local media archive.
Hugin combines overlapping photographs into panoramic images and other stitched compositions. It exposes alignment and projection controls for photographers who need more intervention than a camera or automatic phone panorama provides.
Scribus is desktop publishing software for arranging text and images into brochures, magazines and other page-based documents. It gives print-oriented projects control over layout, color and PDF output.
FontForge is a desktop font editor for drawing glyphs, adjusting spacing and generating font files. It gives type designers access to a detailed toolset for creating or repairing typefaces.
Birdfont provides a visual workspace for building glyphs and exporting fonts. Its editions distinguish open-source code from packaged binaries, with different permissions for free-font creation and commercially licensed font work.
