Formatting: jsonvet fmt rewrites files in all six dialects and keeps their comments.
Editors: Only files on disk are checked (file: URIs), since the settings are picked by the file's path.
Design: What jsonvet promises, and why it is built the way it is.
Conformance: How 27 parser runs treat the same files in JSON5, JSONC, JWCC (HuJSON), JSON Lines and strict JSON: 18 other parsers, plus jsonvet in each dialect and the duplicate-key variants.
Accessibility: axe-core at 390 px and 1440 px wide, in light and dark mode, and by hand with the keyboard alone (2026-11-06).
Assurance case: This page argues why jsonvet meets its security requirements, and names the code, test or workflow behind each claim.
Decisions: Each record is a choice where we measured or argued an alternative and turned it down, with the numbers, so nobody argues it again without new evidence.
