Postme is a simple and powerful HTTP client for API developers and testers.
Main features:
• Multiple tabs — work with several requests at the same time.
• HTTP methods: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS.
• Parameters, headers, and body editors (form-data, x-www-form-urlencoded, raw JSON/XML, binary).
• Authentication: Basic and Bearer tokens.
• mTLS support — client certificate + private key (PKCS#8 PEM), with optional passphrase.
• SSL verification toggle.
• Import Postman collections (JSON) and continue testing on mobile.
• Collections manager — save, duplicate, and organize your requests.
• Variables support — reuse values across requests.
• Auto-save — your tabs and settings are restored when you reopen the app.
• Lightweight, modern UI optimized for developers.
Postme does not collect or share your data. All requests and settings stay on your device.
