The single biggest piece of friction in any web app is the login screen. You land on a homepage, click "Try it", and… you're staring at a "Sign in with Google" button. For a free tool, that's a deal-breaker for a huge percentage of visitors. So we removed it.
What changed
When you visit freeflowcharts.app today, you land directly in the flowchart editor. Drag nodes, connect them, type labels, change colors, switch themes — all without typing an email address.
Your work is held safely in your browser's localStorage until you choose to create an account. When you do, it's a one-click migration to the cloud.
Why we did this
Three reasons.
1. Visitors who can't immediately try the app, leave. Modern web users have ~3 seconds of patience. A login wall before any value is delivered is the highest-friction interaction in the funnel. Removing it lets people experience the product before deciding whether to commit.
2. Search engines crawl the actual app now. Previously, Googlebot would land on a static "Sign in with Google" page when crawling freeflowcharts.app. Now it crawls the real editor — drag-and-drop canvas, 20+ node types, themes, AI assistant, export options. Better signals about what we actually do, better SERP ranking.

What still requires sign-in
We didn't remove all logins — we just moved them to where they actually matter:
/view/ URLs that anyone can open.When you click any of these as a guest, a sign-in modal pops up in place — so you don't lose your work-in-progress.
How guest auto-save works
While you're a guest, every change to your flowchart triggers a debounced 1.5-second auto-save to your browser's localStorage under a single key (ffc_guest_flow_v1). Refresh the page, close the tab, come back tomorrow — your work is still there.
The header shows ✓ Saved locally instead of ✓ Saved to make this explicit, with a subtle "Sign in to save" link next to it.
When you eventually sign in, your guest flow is preserved — you can move it to your account or start fresh.
What about sharing as a guest?
You can build flowcharts as a guest, but sharing them online requires an account. This is a deliberate trade-off: shared links live on our servers and need to be tied to some identity for moderation and abuse-control purposes.
If you want to share, the sign-in flow takes 5 seconds with Google or email — and then your in-progress flow is automatically uploaded.
What about the API?
Nothing changes for the public flowchart API. It's still:
The web app and the API now mirror each other in spirit: try first, sign up only when you need persistence or premium features.
A small UX note
We thought hard about whether to default the homepage to "guest editor" or "marketing splash page with login button". The marketing-first version had clear info architecture: tell, then show. But it added one extra click before users could try anything — and analytics showed a measurable drop-off at that step.
The guest-editor approach is bolder: show, don't tell. Drop visitors into a working canvas and trust the product to sell itself. It's the same philosophy as Figma, tldraw, and Excalidraw — and it works because flowchart-builders are visual products. You don't need to read a brochure to understand them.
Try it
freeflowcharts.app — open in a new tab and you'll land on the editor immediately. Drag a few nodes around. Connect them. Change the theme. Export. All without typing an email address.
When you're ready, the sign-in button is right there in the top-right corner.
