# About

just trees is a free collection of browser tools for inspecting URL query strings, PHP var_dump output and JSON. The workbenches turn nested input into a tree, with paths, alternative views and exports to help you understand its structure.

Parsing and code generation run locally in your browser. There is no remote parsing API or hosted MCP server. Input is not sent to a parsing server. Share links contain input, so only share data you intend other people to read. See the privacy notice for information about browser storage, analytics and advertising.

After the application has loaded and its resources have been cached, the workbenches support offline use. Each host needs its own cached resources. Browser storage can be cleared or evicted, so offline availability depends on what has been saved on your device.

In supported browsers, WebMCP exposes browser-local tools for parsing and code generation. This is a browser capability, not a remote service; availability depends on browser support. The agent guides describe the supported tools, input limits and output formats.
