Hi DH, we’re building Haystack Editor (https://haystackeditor.com/), a canvas-based IDE that automates the boring stuff (plumbing, refactoring, and finding code) so that you can focus on the exciting parts of software development! You can see a quick overview of Haystack at https://youtu.be/c2uZnR5D_cc Haystack was born out of our frustrations with working in large and mature codebases, specifically with navigating and editing functional flows (e.g. the code flow for adding an item to the Amazon shopping cart). Oftentimes dealing with such flows would involve navigating a maze of files and functions, and making any edits would involve a lengthy process of doing corresponding downstream/upstream plumbing. Haystack attempts to address this in the following ways: 1. It allows you to explore your codebase as a directed graph of functions, classes, etc on the canvas. We feel like this better fits how your mind understands your codebase and helps you find and alter functional flows more intuitively. We especially want to utilize this for pull request reviews! 2. It has a navigational copilot that makes edits across files or functions much easier. After you make some changes, Haystack will try to predict your next action and create functions/methods or refactor upstream/downstream code for you. Haystack will surface these speculative edits on the canvas in a way that you can easily dismiss or incorporate them, allowing you to make large changes with a few clicks or keystrokes. 3. Haystack will utilize natural language search so you don’t have to play “Where’s Waldo” to find a functional flow in your codebase. This is coming soon! We’re still pretty early in development and we really want to perfect the experience of navigating and editing code on a canvas. Any feedback would be much appreciated! PSA: Since Haystack is a VS Code fork, you should be able to move your extensions and keyboard shortcuts. Please let us know if you have any issues with this!

Key features

6 features of Haystack Editor

Diff-based case generation — Reads code diffs and automatically builds test cases from real customer journeys without writing tests.
Production snapshot forks — Creates a full replica of your services, databases and queues for each case, isolated from live prod.
Parallel case execution — Runs all generated cases simultaneously, comparing results with and without the change.
Live failure environments — Keeps a live replica of the failing environment with before/after screens and network traces.
CLI & agent loop — Command-line tool (haystack verify) and integration loop for coding agents to auto-fix failures.
Unlimited verification — No per-seat or per-run limits; verifies unlimited changes and cases per change.
