Haystack Editor

Haystack Editor blends a traditional code editor with a canvas‑based workspace, allowing developers to view and manipulate code structures visually. The canvas workspaces display relationships between files and functions, while the explorer view and keyboard navigation provide quick access to project components. Editing, navigation, and lightweight debugging are integrated, and the editor supports extensibility through built‑in extensions that add language grammars, snippets, and richer language features such as code completion and “go to definition.”

The product is released under the PolyForm Strict License 1.0.0 and is maintained as an open‑source, free‑tier project. Updates are issued weekly, and the code runs on Windows, macOS, and Linux. A roadmap and contribution guidelines are publicly available, encouraging community involvement through bug reports, feature requests, and pull‑request reviews.

Target users are developers who want a visual overview of codebases without leaving a familiar editing environment. The canvas UI aims to improve code comprehension at a glance, while the extensible architecture lets users tailor language support and tooling to their workflow.
