Hey HN! I’m Robert. I worked on [Percy’s SDKs/support from 2018–2022.](https://github.com/percy/cli/graphs/contributors) If you ever reached out to support or opened an issue, I probably helped you. Hopefully it was positive :) After a few years away, visual testing still felt stuck, so I'm building Vizzly. The problem: Design handoffs kinda suck. Designers make beautiful specs, devs implement them, then everyone realizes the details got lost somewhere. Current visual testing tools catch broken CSS but miss the real issue - making sure what ships actually…

VizDiff▲110Hey HN, I built VizDiff, a streamlined visual regression testing tool specifically designed for Storybook components. I found existing services like Chromatic powerful, but often too feature-heavy or costly for smaller teams and bootstrapped startups. VizDiff simplifies automated screenshot testing—capturing component snapshots in CI, clearly highlighting pixel-level visual changes, and helping teams catch UI regressions before they reach production. My main goal was accessibility and ease of integration for small teams or solo devs who need effective visual testing without the overhead. I'd…

Hi HN, my name is Rahul Sarathy and I built Homer (https://usehomer.app), a tool to allow creators to build more interactive digital textbooks. Right now the software supports image based scrollytelling with a roadmap to add interactive components such as annotations, animations, backlinks, and more. You can check out a demo of an interactive history book here: https://usehomer.app/demo Here's another short example of how a personal finance related book could look like: https://usehomer.app/rahul/8 If you're interested in checking out the UI used…

Directed acyclic graphs are muched discussed in comp-sci, but octopus appears to be the first reusable, turnkey, ready-to-wear, off-the-shelf implementation of a DAG for application development, in any language, that I'm aware of. This is remarkable because DAGs hit a sweet spot in the middle of the three common programming paradigms (OO, event-driven, functional). Let's have a DAG as the top-level structure of our applications. Data-fetching and onChange handlers live in DAG nodes, next to the data they act on. The UI flows out from the DAG with fine-grained reactivity. Our app state is…
