Do I get free credits to try JSON Schema Diff?

Yes — new accounts get 3 free credits to spend on any tool, JSON Schema Diff included. After that you only pay for what you run.

How many credits does JSON Schema Diff cost?

Everything runs in your browser and nothing is uploaded: free accounts pay 1 credit per run, and Pro or Pro+ members run it as often as they like.

Is the content I paste private?

JSON Schema Diff uses your input only to generate the result. Stored results are deleted automatically by our retention policy, and you can remove any run from your history.

Do I need to install anything?

No. JSON Schema Diff works in any modern browser — nothing to download or install.

JSON Schema Diff

Compare two JSON Schemas and see what actually changed: properties added or removed, type and format changes, required fields and enum values.

Compare two JSON Schemas

Paste an old schema and a new schema. Each structural change is listed with its path.

Schema A (before)Schema B (after)

Nothing compared yet

Paste two schemas above, then press “Compare”.

This is a structural diff: it tells you what changed, not whether the change is backwards compatible. Array items and nested objects are compared recursively.

Runs entirely in your browser. Nothing is uploaded.
