What is Polter.io?
Stop waiting for the backend. Start building today. Polter.io is an elite, lightweight desktop application engineered for modern frontend and full-stack developers who want to eliminate API bottlenecks. Built entirely in Rust and Tauri, Polter lives right in your system tray as an intelligent network proxy that effortlessly bridges the gap between a missing backend and a working frontend. We’ve all been there: frontend development grinds to a halt because a team member hasn’t deployed an API endpoint yet, or because writing a temporary "fake" local controller feels like a massive waste of time. Polter fixes this with Smart Hybrid Interception. It routes 90% of your development traffic to your real staging or production API, but the moment a 404 occurs, Polter instantly intercepts the request and injects a locally defined, lightning-fast JSON mock. No complex Nginx configurations. No manual /etc/hosts hacking. No bloated Electron-based enterprise suites. Just zero-config, native speed that keeps you in your flow state.
Key Features
Smart Hybrid Proxying
Keep using your real API for everything that works. Polter transparently passes your traffic through, only intercepting and mock-injecting specific endpoints or routes that aren't ready yet.
The Chaos Engine (Pro)
Test how your frontend actually behaves under stress. Use a simple slider to introduce artificial network latency, packet throttling, or random 5xx server errors to ensure your app is resilient before hitting production.
Local Stateful Mocking (Pro)
Go beyond static files. Polter understands application state. If you execute a POST request to a mock endpoint, a subsequent GET request will automatically reflect those changes in its temporary, embedded local database.
One-Click SSL & HTTPS
Wrestling with self-signed certificates is over. Polter handles local HTTPS configuration natively on macOS and Windows, letting you test secure webhooks and secure API requests with zero friction.
