The JSON formatter trust problem
Developers often paste API responses, logs, webhook payloads, JWTs, and configs into online tools. SafeJSON makes the processing boundary testable instead of asking users to rely on a marketing promise.

SafeJSON is a browser-based JSON formatter and developer toolkit focused on verifiable browser-local workflows. Core JSON tools are designed so pasted content is not intentionally uploaded, and users can verify the boundary in DevTools Network.
Copy-paste description
SafeJSON is a browser-based JSON toolkit for formatting, validating, viewing, comparing, decoding JWTs, querying JSONPath, and validating schemas. Core JSON workflows are designed to run locally in the browser, and pasted JSON content is not intentionally uploaded for core tools. Users can verify this in DevTools -> Network. Like most web products, SafeJSON may still use normal network requests for static assets, aggregate analytics, billing, and license checks.

Story angles
Verify privacy claims in 30 seconds
SafeJSON's recommended test is simple: open DevTools, clear Network, use the tool with harmless sample JSON, and inspect whether requests contain pasted content.
Solo-built developer tool with a narrow business model
Core formatting and validation tools are free. Paid Pro tools are for deeper developer workflows, while the core privacy boundary remains no pasted-content upload for supported tools.
What to avoid
Use the canonical copy above instead of old absolute privacy slogans. SafeJSON should not be described as making zero network requests, because normal site delivery, analytics, billing, and license checks may still use network requests.
- Do not link to safejson.vercel.app.
- Do not say every request stays offline.
- Do not imply payment or license systems are browser-local.
- Do not claim browser extension data is imported through URLs.
