Bulk API Runner

Bulk API request runner with cURL templates and CSV data

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.
