Zlab is a free-form board for sticky notes, text, and images. Spread a project out, drag the pieces around until they make sense, and zoom out to see the whole thing at once. No account. No server. It all lives in your browser.

There's nothing to set up. Zlab is one page that behaves like a whiteboard with a memory — everything you place is saved as you go.
It runs entirely in your browser. Install it as a PWA and it opens like a native app — and keeps working offline.
Sticky notes with a real markdown editor, big text for the ideas that need to be loud, and image cards for the visual stuff.
Drag cards anywhere, resize them from the corner, right-click for context actions. The focused note answers to the keyboard, too: ctrl + del deletes it, ctrl + e exports it.
The board is bigger than your screen. The minimap in the corner shows the whole spread and where you're standing in it.
Most canvas tools want an account and a subscription before they'll remember your work. Zlab just remembers — locally, instantly, and for free.
Every note is a real markdown document with syntax highlighting, edited in place. A dot tells you when it's saved — which is always, a split-second after you stop typing.
A 3000 × 3000 canvas you pan by scrolling. Cards drag and resize smoothly and track your cursor exactly — no snapping you didn't ask for, no grid you can't escape.
Big hand-set text for titles and mantras, images for references and mood. Image cards keep their aspect ratio when you resize them, like they should.
A live miniature of the entire board sits in the corner, with a viewport indicator that follows you as you scroll. Getting lost is opt-in.
Add Zlab to your home screen or dock and it launches like an app, full-screen, and works offline. Your boards are stored on the device, so a dead connection changes nothing.
Export your whole board to a JSON file and import it anywhere else — another browser, another machine. No lock-in, because there's no server to be locked into.
Zlab has no backend. Boards are saved to your browser's local storage the moment you make them, and the only copy that exists is the one on your machine.
Notes, text, and images persist in local storage — closing the tab doesn't lose a thing, and no analytics or tracking ever phones home.
One click exports the whole board as JSON. Move the file, back it up, or hand it to someone else — it's a file, not a hostage.
Local-first is the foundation, not the ceiling. Anything networked that ever gets added will be optional and self-hostable — that's the house rule for every Klectr app.
Clone the repo, run it locally, and pin it to your browser. Your first board is about ten seconds away.
