よくある質問
Is it safe to paste confidential production API keys or passwords?
Yes, 100% safe. PhuDuy Tools executes entirely inside your client browser RAM via JavaScript Web Workers and standard Web Crypto APIs. No requests or payloads are ever dispatched to any external server.
What is the maximum JSON payload size supported?
Because parsing is performed client-side, the only limit is your device physical RAM. You can comfortably format and search JSON files up to 50MB-100MB with instantaneous responsiveness.
Do these developer tools require an account or subscription?
No account, sign-up, or payment is required. All 33+ developer micro-tools are free forever for open-source and commercial use.
