draw.io is a free diagramming application for drawing technical diagrams and web-based sketching. Diagrams can be stored in online storage platforms, a browser, a local device, or offline with a standalone desktop app. It integrates with platforms including Atlassian Confluence and Jira, Google applications, GitHub, GitLab, Microsoft applications and Notion.
ParaView is an open-source, multi-platform data analysis and visualization application built to analyze extremely large datasets using distributed memory computing resources. It runs on Linux, macOS and Windows, from laptops to supercomputers, and includes readers for many file formats and more than 200 filters. It can also run in situ using ParaView Catalyst and in a web browser using trame.
PlantUML is an open-source tool that uses simple textual descriptions to draw UML diagrams. It supports diagram types including sequence, use case, class, object, activity, component, deployment, state and timing diagrams, plus non-UML diagrams. Images can be exported in PNG, LaTeX, EPS and SVG.
Terminal Render is a storage, design, or frontend resource for mockups, assets, UI tools, or web search.
Swimlanes.io is a free webapp for making sequence diagrams. Users edit text and the diagram updates in real time. Diagrams can be downloaded as images or shared with a link, and the URL changes whenever the diagram is updated.
Flourish is a storage, design, or frontend resource for mockups, assets, UI tools, or web search.
Dia is free, open-source drawing software for creating structured diagrams. A Windows version is available as a free download, and the download page also provides packages for Mac OS X and Linux. The software is released under the GNU General Public License, GPLv2.
