Frequently Asked Questions
Check here first before reaching out, we might have already answered your question!
Is my data sent to your servers?
No. Every tool runs entirely in your browser. Your data, whether JSON payloads, JWTs, or Base64 strings, is processed on your device and never transmitted anywhere.
Is Developer Toolkit really free?
Yes. All browser tools are free with no paywalls, and that will not change. A paid REST API tier for CI/CD automation may come later, but the UI tools stay free forever.
Are there any rate limits or usage caps?
No. The tools run locally on your device, so there is nothing to throttle. No rate limits, no usage caps, no restrictions of any kind.
Why use this over other generic tools?
We handle edge cases that generic tools miss: JSON BigInt precision loss (Snowflake and Twitter IDs), duplicate keys, and trailing commas. Every tool also has a keyboard-first UX with shortcuts like Ctrl+Enter to run and Ctrl+K to clear.
Can I use this offline?
Yes. Once the page has loaded, all processing happens in your browser. You can lose your connection and every tool will keep working.
Do I need to create an account?
Never. No sign-up, no login, no tracking of any kind. Open a tool and use it.
