About Rester : REST API Client

Rester is a powerful, beautifully designed REST API client built to test, debug, and interact with APIs directly from your mobile device. Whether you're on a commute, away from your desk, or just prefer mobile — Rester has you covered.

SEND REQUESTS INSTANTLY

Craft and fire HTTP requests with support for all major methods: GET, POST, PUT, PATCH, and DELETE. Set custom headers, configure request bodies, and see detailed responses — all from one clean interface.

FLEXIBLE REQUEST BODY

Choose the body format that fits your use case:

• Raw (JSON, XML, plain text, etc.)
• Form Data (multipart)
• URL Encoded

BUILT-IN AUTHENTICATION

No need for manual header setup. Rester supports:

• Bearer Token
• Basic Auth (username & password)
• API Key (placed in header or query parameter)

COLLECTIONS

Organize your API requests into collections. Save, name, and reorder your requests so you can find and rerun them effortlessly.

ENVIRONMENTS & VARIABLES

Define environments (Development, Staging, Production) with custom variables. Use {{variable}} syntax in your URLs, headers, and body — and switch contexts in a tap.

REQUEST HISTORY

Every request you send is automatically saved. Browse your history and quickly resend previous calls.

DETAILED RESPONSE VIEWER

Inspect responses with:

• Status code & status text
• Response time & size
• Full response headers
• Formatted response body (JSON, XML, HTML, plain text)

💾 100% OFFLINE & LOCAL

All your data — requests, collections, environments, and history — is stored locally on your device using SQLite. Nothing is sent to any server. Your data stays yours.

MODERN, PREMIUM DESIGN

Rester features a sleek, dark-first UI with:

• Light, Dark, and System theme modes
• Smooth animations and intuitive interactions
• Clean typography and vibrant color palette
