Method
Ajv compiles the pinned draft-07 source in a disposable worker. Validation never coerces, inserts defaults, or removes properties.
Limits
Schema ≤120,000 characters, data ≤500,000; schema depth 32 / 5,000 nodes, data depth 40 / 10,000 nodes. Only local # references; formats are not checked. Patterns ≤200 characters. At most 100 errors are shown.
All work stays in this browser. Each disposable worker is terminated after 2.5 seconds or cancellation. Inputs and processing logs are not sent to analytics.
Your inputs stay on this device. Only optional, consented page visits are measured. Input values, files, filenames and processing logs are not sent to Analytics.
When switching languages, text, settings and selected files are temporarily kept on this device. Transfers are removed after restoring; interrupted transfers are cleaned up on a later visit. Inputs and files are never uploaded.
