Interactive, automated, browser-based, or agent-driven
Use JSONBuddy as a Windows JSON editor, from CLI/CI, through supported API workflows, from AI agents, or in focused browser tools. Platform pages explain access; solution pages keep the customer outcome primary.
- Desktop: interactive JSON and JSON Schema editing on Windows.
- CLI / CI: repeatable validation and conversion in automation.
- Web API: use the public service contract for supported remote operations.
- AI agents: use AI-agent workflows; ValBuddy for Codex stays distinct.
- Browser tools: focused in-browser workflows remain intentionally unlinked.
