What's the best software for creating flowcharts and other visuals to document application logic?

I'm looking to create some flowcharts, but I'm only aware of the obvious solutions like PowerPoint or Keynote. Does anyone have any suggestions?

Here's an example of a decently complex flowchart, via Slack:

Mermaid is awesome with the corresponding plugin for Visual Studio Code: marketplace.visualstudio.com/items...

When I need something prettier than Dia, I resort to PowerPoint. I love Dia for being cross-platform.

Mermaid is really great for "coding" diagrams. I mainly use it fro sequence diagrams.

The beauty is, you can embed it everywhere you can run JavaScript.

Sparx Enterprise Architect is perfect for UML. Not so to document physical data models.

Anybody know of an interactive flowchart software where you could step through the flow?

+1 for yEd and Draw.io. I also like websequencediagrams.com for documenting messaging flows between components.

I have been using PlantUML for all my thesis figures almost. Besides that, at work we use Gliffy as a plugin to Confluence. Furthermore, draw.io is a good alternative which is free.

The big advantage I found about PlantUML is the automatic routing and layout it generates. And as it just writing the PlantUML language, it works quite fine!

I first started with Astah but found it completely useless, then I discovered draw.io and it's a big improvement. It's far from perfect, but it's great for collaborating.

the best one's missing :-)
Draw.io - draw.io

A browser-based, feature rich (stencil lib, visio im-/export, etc), well maintained, free and open source diagram editor. Has UML stencils for your use case.

Available as a free software as a service, as an oflline app (Chrome App in the Chrome store) or as web app for self-hosting. They earn money from selling a draw.io Confluence plugin (which is based on the open source draw.io, but is not not open source by itself). I highly recommend it if you use Confluence as the company wiki.

I would alwyas prefer draw.io over gliffy, Visio Online, etc.

especially since they offer an offline version...

fancy export facilities, to png, svg and other formats.

Draw.io is definitely the best choice if you want only handful of charts without any super sophisticated features 😊 .For a developer like me this tool is more than enough.

Yeah, I second that recommendation, too.

Draw.io is not perfect and has some rough edges (e.g PDF export requiring contact to an external server) but has a quiet impressive featureset and is just helpful in getting things done.

I'll second for draw.io. I'd much rather be coding than drawing, and draw.io is a slick tool that gets me back to the work I love ASAP.
