o-flow gives you a fixed kit of meaningful shapes, five tidy sizes and a grid that everything snaps to — so every diagram your team makes looks 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 — unlimited objects and canvases.
Most diagram tools give you infinite freedom and you end up with wonky boxes and inconsistent styles. o-flow constrains the messy bits so your team produces standard, reviewable diagrams every time.
Move anything and it locks to a 20px grid. Five fixed sizes per shape mean boxes line up edge-to-edge and centre-to-centre — no nudging.
A diamond is always a decision; a cylinder is always a datastore. Pick by meaning, not by drawing. There's even a Person card — name, role and photo — for org charts and ownership.
Toggle to the code panel and edit your diagram as plain text. Change a colour, size or position and the canvas updates live. Perfect for version control.
Invite your team to a canvas and edit together in real time. See each collaborator's cursor, labelled with their profile, as they work.
Organise diagrams into folders, save versions, and pick up where you left off. Export to SVG, PNG or JSON any time.
20 curated colour themes (5 dotted), consistent black-on-light text, system-coloured cylinders. Beautiful, on-brand diagrams without a design review.
Drag a box anywhere; it snaps. Hit Tidy and o-flow aligns every column and spaces it evenly. Because widths are multiples of the grid, connectors land perfectly straight every time.
Every diagram has a clean text representation. Tweak size, style or position in the
Code tab and watch the canvas redraw instantly. Paste a spec, get a diagram. Diff it in a pull request.
Invite teammates to any design. Everyone edits the same canvas at once and sees each other's labelled cursors moving in real time.
