How does Multi-Tab Request Workspace work in 1DevTool?

Step 1: Set Up Your Request — Choose the HTTP method, enter the URL, and configure headers, auth, and body in the tabbed interface. Step 2: Send & Inspect — Hit send and see the response instantly — formatted JSON, headers, status code, and latency metrics. Step 3: Save & Organize — Save requests in tabs for quick re-use. Each project maintains its own request workspace and URL history. Step 4: Share & Debug — Copy as cURL for sharing. Send response data to your AI agent for analysis or debugging assistance.

Why You Need This

How this feature boosts your daily productivity

Real API development involves dozens of endpoints. You need to test the login endpoint, then the protected resource, then the webhook callback — often in sequence. Multi-tab workspaces let you keep all your requests open and organized, with full history tracking. Save up to 50 requests per project and switch between them instantly. No more retyping URLs or rebuilding request bodies from memory.
