Hey Product Hunt community! 👋
I’m Johan, creator of forkstorm.
Why I built this
Whenever I brainstorm on a standard digital whiteboard, I run into the same problem: as soon as an idea splits into two alternative directions ("what if we design it like this instead?"), you either have to:
Copy-paste everything across an infinite canvas and clutter the board, or
Keep undoing and lose what you just had.
As developers and builders, we take branching and commits for granted in Git. I wanted that same non-destructive freedom for visual thinking.
How forkstorm works
Commit: Snapshot your thoughts whenever you hit a milestone.
Branch: Fork any point in your commit tree to explore a totally different direction without duplicating your canvas.
Peek (Layering): Ghost another branch directly beneath your current canvas with a subtle glow so you can compare concepts or build directly on top of an alternative.
Full visual toolbox: Sticky notes, text boxes with clean auto-reflow, filled shapes, lines with anchored endpoints, arrows, freehand drawing, highlighter, eraser, and image upload/paste.
100% Local & Private: No sign-up, no account, no tracking. Everything stays in your browser (IndexedDB), with one-click export/import to .json files.
Try it in 5 seconds
You can jump straight into forkstorm.com and click "Try an example" to see a branching scenario in action immediately. No login required.
I’d love to hear your thoughts:
How do you currently manage alternative concepts or iterations when sketching ideas?
What tools or integrations would make this part of your daily workflow?
I’ll be here all day answering questions and reading your feedback. Thank you for checking it out! 🚀
