Bulk API Runner

About

Bulk API Runner lets you execute hundreds of API requests in seconds — no code, no scripts, no Postman collections.

HOW IT WORKS
1. Paste any cURL command and use {{variable}} placeholders for dynamic values
2. Upload a CSV file — columns auto-map to your placeholders
3. Hit Run — watch requests fire with a live progress bar and real-time results

FEATURES
• cURL Parser — Paste cURL commands copied straight from Chrome DevTools. Supports all common flags (-X, -H, -d, --data-raw).
• Placeholders — Use {{any name}} in the URL, headers, or body. Supports names with spaces like {{Partner ID}}.
• CSV Upload — Drag-and-drop or browse. Previews your data and auto-maps columns to placeholders.
• Concurrency Control — Run 1 request at a time or up to 20 in parallel.
• Adjustable Delay — Add a pause between requests to avoid rate limits.
• Live Results — Color-coded status codes, response preview, duration, and the final cURL for each request.
• CSV Variable Columns — See original input values alongside each result to quickly identify failures.
• Export — Download all results as a CSV for further analysis or retry.
• Dark/Light Theme — Matches your system preference, or toggle manually.

BUILT FOR
• Retrying failed API calls in bulk
• Migrating or backfilling data via APIs
• Load testing endpoints
• Any repetitive API task where you'd normally write a script

All requests run locally in your browser. No data is sent to any third-party server.
