Built for Power Users

Everything you need to analyze, debug, and transform your data.

Large-File Ready

Graph processing runs outside the React render path, opens large files with a shallow preview, and loads deeper branches on demand.

Multi-Format

Seamlessly switch between JSON, YAML, XML, TOML, and CSV. Copy and paste or drag and drop files.

Security & Privacy First

Everything happens 100% locally on your machine. Your data never touches any server. Performance first, security always.

JQ Query Engine

Filter and transform your data using powerful JQ syntax directly in the app.

Code Generation

Instantly generate TypeScript interfaces, Go structs, or Pydantic models from your JSON.
