Turn system architecture into diagrams people actually explore
FlowDocu is an interactive technical documentation tool for engineering teams. Model your APIs, databases, queues, and services as a living diagram — click through it step by step, switch between happy-path and failure scenarios, present it to a room, and export it — instead of another static boxes-and-arrows diagram nobody opens again.
Free forever plan · No credit card · Set up in minutes
Step-by-step playback
Animate a request through every hop in your architecture, one step at a time, so teammates see the flow instead of guessing at arrows.
Scenarios, not one diagram
Model the happy path and every failure path on the exact same canvas, then switch between them instantly during a walkthrough.
Present & export
Walk a room through it slideshow-style, or export a clean PNG, scalable SVG, or an animated GIF when you're done.
Docs live on every node
Attach real API endpoints, queue topics, or database schemas to each component, then try them with a built-in mock request runner.
A colorful component library
Pick from a built-in icon set for every component — or upload your own logo — so a diagram reads at a glance, not just on hover.
Share & collaborate
Keep a flow private to your workspace, share it as a public read-only link, or invite teammates to a shared project.
From blank canvas to shared walkthrough
Build
Drag components onto the canvas, connect them, and describe each one — from a quick sketch to full API/DB documentation.
Animate
Define scenarios and press play to watch a request move through your system, hop by hop, in real time.
Share
Present it live, export an image or GIF, or send a link so anyone on your team can explore it themselves.
