    Easy and intuitive interface, really like the customization options. Fills a true gap in the design process.


    Needs more powerful integration into existing tools, which I'm sure is already planned.

    Have been waiting for a tool like this for a while, really glad to see the work you have put into this 🙏

    Would love to see more powerful integration with Sketch/Zeplin/Invision. Automatically migrate Sketch Prototyping flows into Overflow. Ability to Export to Zeplin/Invision.

    Best of luck, looking forward to see more!

    Easy to use, fills a much needed gap in creating task flows


    Want to integrate into my InVision, Sketch Cloud, or Purple.PM Workflow

    Great tool to create task flows. If can now integrate into an existing workflow and cloud, this will be a very very valuable tool in the designer's toolkit.

👏👏👏 it's what we are waiting for! A tool to build and share storyboards/user-flows more efficiently. Please, don't do the same mistake of all other prototyping tools which think that we only design for mobile. We also do web, desktop app, TV app and more.

@brnltn We definitely haven't forgotten about you! Overflow takes all types of devices into account.

@brnltn @hesperiashimo It's really encouraging to see your reactions. We're eager to see how Overflow will boost your workflow!

Hey Product Hunt! 👋 We’re super excited to introduce Overflow, the world’s first user flow diagramming tool tailored for designers. We set out to reinvent how user flow diagramming should be done, the right way and that is why we’re building Overflow. Overflow is a powerful tool that integrates and syncs seamlessly with the most popular design tools to allow designers to create beautiful user flow diagrams. It gives designers and product managers the flexibility to present their ideas like a maestro, by navigating between their screen designs comfortably and focusing on the details when needed. Overflow will be publicly available in just a few weeks, but you can sign up for early access to our beta and be one of the first to experience Overflow. 🙏 Questions or feedback? We'd love to hear from you. Cheers!

@alexispiperides can you summarise the benefits of overflow + sketch versus sketch’s inbuilt flow tool?
Alexis PiperidesMaker@alexispiperides · CEO, PROTOIO Inc.
@daniel_oertli The latest Sketch update offers features to build rapid prototypes. Overflow is a desktop tool that allows you to create user flows and style your connectors as you see fit and present them in a playable way. Overflow supports the new Sketch features and goes a step further to allow you to customize the look and feel of the connectors, remove the 'unnecessary' connectors, apply device skins and more.

Very clean! Excited to get in and test it out. The current process of user flows is so tedious.
Stefan ManssonMaker@animify · Software Engineer @ Proto.io
@amandasabreah Hey Amanda, we're really excited to release Overflow to solve that exact problem, glad it'll be of use!

This is exactly what we're looking for! We currently do these types of user flows by hand, and it is TEDIOUS! User flows are so important to grasp the big picture of a project. So excited to try this out :)
Stefan ManssonMaker@animify · Software Engineer @ Proto.io
@craigphares We feel you Craig, it's tough. We're as excited to put Overflow in your hands to end that!
Chrystalla PieriMaker@chrystallapieri · Marketing manager @Proto.io
@craigphares Hey Graig :) and that is exactly why we're building Overflow.
