An alternative to Inkscape for scientific figures
Inkscape and BioDiorama are both free, so the difference is not price — it is what you start from. Inkscape gives you an empty canvas and a full set of vector tools; BioDiorama gives you 27,200 ready-made 3D biology and chemistry models, about 13,000 science icons, about 500 ready-made biology diagrams and about 320 templates and a 3D studio to pose them in, so a cell, a mouse or a protein is something you pick rather than something you draw. BioDiorama runs in the browser with nothing to install, and exports layered SVG, so a figure started here can be finished in Inkscape whenever you want its deeper vector tools.

At a glance
| BioDiorama | Inkscape | |
|---|---|---|
| What it costs | Free. | Free and open source. |
| Getting started | Open a web page. Nothing to install. | Download and install the program. |
| What you start from | Ready-made models, icons, diagrams and templates, found by searching for the thing itself. | An empty canvas. Scientific artwork has to be drawn, or imported from an icon set. |
| Drawing by hand | Draw shapes and free paths, then double-click to move points and curve handles, and turn text into outlines. | A deeper vector toolkit: boolean path operations, filters, extensions, pattern and clone tools. |
| 3D | A full 3D studio: pose, light, cut open and animate models, then send the view to the page. | Flat vector drawing only. |
| File formats | Editable PowerPoint (.pptx), layered SVG, 3D models (.glb), PDF, and TIFF or PNG up to 600 dpi. | SVG natively, with PNG, PDF and EPS export. |
| Offline | Needs the page loaded; the work itself is saved in your browser. | Runs entirely offline. |
| Print colour | RGB, with colour-blind-safe publication palettes and a colour-blindness check. | Supports CMYK workflows for print. |
What you get by switching
- A cell, an organ, a plasmid, a culture plate or a lab mouse is a search away, at the angle you want, instead of an afternoon of bezier curves.
- Node editing and text-to-path are there when you do want to draw — double-click a shape to move its points and curves, as in Inkscape.
- Nothing to install, so it works on a locked-down lab computer, a borrowed laptop or a tablet.
- SVG export keeps named layers, vector shapes and real text, so Inkscape can pick the figure up exactly where you left it.
- Publication colour themes, including Okabe–Ito and Paul Tol’s colour-blind-safe sets, applied to a whole figure at once.
- Every open-licence picture carries its credit line, gathered for your legend at export.
Where Inkscape is still the better tool
Said plainly, because picking the wrong tool wastes more time than any figure saves.
- Inkscape is the deeper vector editor: boolean path operations, filters, live path effects, extensions and scripting have no equivalent here.
- Inkscape works offline and is open source, which matters if you need to keep working on a plane or audit the code.
- Inkscape handles CMYK and print-shop colour; BioDiorama works in RGB.
- For a logo, a leaflet or anything that is not a scientific figure, Inkscape is the right tool.
Moving a figure across
- Open biodiorama.com and go to the 2D Studio.
- Search the picture library for what you would have drawn — it searches BioDiorama’s own icons and models together with Servier Medical Art, NIH BioArt, Bioicons, Reactome, PhyloPic and more.
- Lay out the panels, arrows and labels, or start from one of the ready layouts.
- Export SVG. Layers keep their names, shapes stay vector, and text stays text.
- Open that SVG in Inkscape if you want its path tools for the last ten per cent.
Questions people ask
Is there a scientific icon library for Inkscape?
Yes — Servier Medical Art, NIH BioArt and Bioicons are all openly licensed and can be imported into Inkscape. BioDiorama searches those same sets alongside its own 27,200 models and 13,000 icons, and attaches each one’s credit line for you.
Can I keep editing a BioDiorama figure in Inkscape?
Yes. SVG export gives named layers, vector shapes and real text, so everything is still editable in Inkscape, Illustrator, Figma or Affinity.
Does BioDiorama let me edit paths like Inkscape does?
It lets you move points and curve handles on any shape you draw, and turn text into outlines. It does not have Inkscape’s boolean operations, filters or extensions.
Which is better for a journal figure, Inkscape or BioDiorama?
If the figure is mostly scientific objects — cells, molecules, organs, equipment — BioDiorama will be much faster, because they already exist. If it is mostly custom vector drawing, or must be finished in CMYK, Inkscape is better. The two work well in sequence.
Does BioDiorama work offline?
The app loads over the web and your work is saved in your browser; Inkscape runs fully offline.
Is BioDiorama open source?
No, and it is not affiliated with Inkscape or the Inkscape project. It is free to use, and the figures you make are yours.
