Flow diagrams that can’t go wrong.
A fixed kit of meaningful shapes, five tidy sizes, and a grid that everything snaps to — so every diagram your team makes comes out consistent, clean and on-brand. Draw it, or write it as code. Work together live.
Free forever 5-object canvas. Teams from £3/user/month inc. VAT.
Most tools give you infinite freedom — and you end up with wonky boxes and inconsistent styles. o-flow constrains the messy bits, so your team ships standard, reviewable diagrams every time.
Always snaps to grid
Move anything and it locks to a 20px grid. Five fixed sizes per shape mean boxes line up edge-to-edge with no nudging.
Shapes that mean something
A diamond is always a decision; a cylinder always a datastore. There’s a Person card too — name, role and photo — for org and ownership charts.
Draw it, or write it
Flip to the code panel and edit your diagram as plain text. Change a colour, size or position and the canvas redraws live.
Real-time collaboration
Invite your team to a canvas and edit together, each cursor labelled with who’s moving it.
Folders & versions
Organise diagrams into folders, keep versions, and export to SVG, PNG or JSON whenever you need.
Standardised styles
Twenty curated themes and consistent black-on-light text — on-brand diagrams without a design review.
Paste a spec, get a diagram.
Every diagram has a clean text representation. Tweak size, style or position in the Code tab and watch the canvas redraw instantly — then diff it in a pull request like any other file.
node a : process "New customer" @ 40,40
node b : process "Verify email" @ 40,120
node c : decision "KYC ok?" @ 40,200
