Launch HN: Haystack (YC S24) – Visualize and edit code on an infinite canvas

Hi HN, we’re Akshay and Jake from Haystack (https://haystackeditor.com/). Haystack re-imagines the IDE by putting it on a 2D digital whiteboard that automatically draws connections between code as you navigate and edit files. We designed it to match our mental model of how code works – as a graph of connected components. Here’s a demo of what it looks like: https://www.youtube.com/watch?v=5XADctpWNNs. You can download Haystack from https://haystackeditor.com/.

We used to work as software engineers at big companies, and when the explosion in AI code-generation tools started we were really excited about them. They gave us a huge speed boost in our day-to-day work. But something was missing: writing code had become easier, but navigating codebases remained painful. We found that we were spending more time on the latter than the former!

Our vision of Haystack is an IDE that helps you navigate your codebase at speed. You should be able to type a vague description of the code you’re looking for (“Show me the code flow that triggers after we click the submit button”) and immediately see the right result. But we don’t think the traditional split-panel interface is the best fit for this type of rapid navigation. Inspired by the fluidity of design tools like Figma (Akshay used to work there!) and Miro, we realized that the canvas layout is a perfect way to represent and operate on code flows, and a great base for all the AI and collaborative tooling we want to build! This is how Haystack was born.

You might have seen our original Show HN (https://news.ycombinator.com/item?id=41068719) about two months ago. Since then, a ton of our users have told us that they’d love to contribute. We’ve made the decision to make the editor source-available so that folks can make contributions and so that they can examine the code to make sure they can trust it. Our repo is at https://github.com/haystackeditor/haystack-editor.

If you’re wondering why we’re going source-available rather than proper open-source: as a startup, we're going to eventually monetize and it’s too early for us to make the decision on whether going fully open-source is the right move. We want to own the distribution of Haystack until we can better understand the ramifications that open-sourcing would have, and whether it’s sustainable business-wise. We’d love to find a way to make proper open-source work, but it’s a one-way door, so we want to take our time to make sure we’re making an informed decision.

We would love to hear about what you think about having a canvas in your IDE and the role visualizations have to play in software development!
