About this project

Visual diffs for JSON and YAML configs, right inside VS Code.

Stackpane renders configuration files as a structured tree and shows you exactly which keys changed between commits, environments or branches. Stop squinting at 400-line diffs to find the one flag that broke staging.

Large config files are loading

The streaming parser is in the 0.9 preview. A 4MB Helm chart opens without freezing the editor now. I still want the worst file you can throw at it.

Smart people. Helpful takes.

    I would pay for a team licence but there's no way to buy one. You've made staying in the Club very easy.

    Genuinely useful for Helm charts. The tree view chokes on files over ~2MB though.

    1. Tom OkaforFounder3mo ago

      Known. Streaming parser is in progress — large files will land in 0.9.

  3. Kwame Asante1mo agoIdea

    A GitHub PR check that comments the structured diff would be the thing I'd actually expense.
