Flostep – Diagrams people can actually walk through

In plain words

Flostep is a tool for creating interactive, walkable diagrams that explain how systems, processes, or customer journeys work. Users sketch components and connect them with labeled arrows to show the order of steps, or let an AI assistant generate the diagram. The result is a live, interactive flow that can be stepped through one stage at a time and embedded anywhere as a link. No account is required to try it.

From the sources

Flostep turns a system design diagram into something people can actually follow. Drag components — frontend, service, database, cache, queue: connect them in the order interactions happen, label each step, then click Next to walk through it one hop at a time. Share it as a public link or embed it in your docs with one iframe; anyone can step through it without an account. No signup needed to try. And via MCP, AI assistant tool can build the whole thing straight from your codebase.

Sketch an interactive diagram of how anything works, or let your AI assistant build it. Then walk through it one step at a time, and embed it anywhere. A live diagram, not a screenshot — scroll down and step through it yourself. Every shared diagram embeds like this, one iframe, any site. From blank canvas to a fully walkable flow in minutes — or watch it happen. Pick from Frontend, Service, Database, Cache, Queue, External API — or create a custom component. Place them on the canvas. Draw arrows between components in the order they happen. Label each one — "POST /login", "returns JWT", "cache miss". Multiple interactions between the same pair are fine. Hit Next to step through each…from flostep.dev

  If you’ve ever tried building onboarding or product adoption with Appcues, Chameleon, Userflow, WalkMe, or Usetiful, you’ve probably hit the same two problems: 1. Everything is rendered with JavaScript overlays 2. Customization is a nightmare A little backstory: When I was choosing an onboarding tool for my previous project, nothing matched what I needed. So I had to build my own. With help from IntroJS I built onboarding solution that I needed: Tooltips, Modals, custom CSS, waiting for interactions, and saving the state into the database. It worked… but it took way more time than it should…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
