Throttlade

About

Slow down specific network requests to test loading states, race conditions, and real‑world performance—without touching your code.

Overview
Modern apps feel fast on localhost, but real users hit slow APIs, flaky networks, and edge cases. Throttlade helps you simulate those moments so you can design and debug with confidence. Create simple rules that delay chosen requests, then watch how your app behaves under pressure: spinners, skeletons, retries, and race conditions become easy to reproduce and polish.

Key Features
- Targeted throttling: match by URL, path, wildcard, or regex
- Per‑method control: apply delays to GET, POST, and more
- Profiles ("Projects"): save rule sets per app or client
- One‑click toggle: turn throttling on/off from the popup
- Live Requests view: see what’s delayed and for how long
- Logs tab: understand exactly what the extension is doing
- Rule priority: reorder to pick the “first match wins”
- Works everywhere: fetch and XHR on any website you open
- Private by design: runs locally, no data leaves your browser

Great For
- Perfecting loading states, skeletons, and spinners
- Reproducing race conditions and timing bugs
- Stress‑testing retries, timeouts, and error handling
- Demonstrating the impact of slow or flaky APIs to stakeholders

Getting Started
- Click “Add to Chrome”, open your app, and click the Throttlade icon
- Add a rule (e.g., delay "/api/*" by 1500 ms)
- Refresh your page and observe your UI under realistic delays

Privacy
