Built for Modern API Engineering

Everything you need to capture, sanitize, and test production endpoints without breaking your development flow.

⚡

Zero-Proxy Native DevTools

No Charles, Fiddler, or local proxy certificates required. Integrates directly into your existing Chrome DevTools pane via Chrome DevTools Protocol (CDP).

🛡️

Automated Credential Redaction

Pre-configured safety net automatically scrubs Bearer tokens, Authorization headers, session cookies, and sensitive payload keys, replacing them with Postman environment variables.

📦

Postman Collection v2.1 Format

Produces fully spec-compliant Postman Collection v2.1 JSON files with organized folders, URL path arrays, query parameters, and raw JSON payloads.

☁️

Direct Workspace Synchronization

Optionally connect your Postman API key and Workspace ID to create collections in your cloud team workspace with a single click.

💻

Instant cURL Generator

Copy any captured endpoint as a ready-to-execute cURL command with masked secrets so you can immediately debug in your terminal or share with colleagues.

🔒

Strict Local Privacy (Zero Telemetry)

All captured data stays in your browser's local memory. No analytics pings, no telemetry, no advertisements, and no tracking databases.

From Browser to Postman in 3 Steps

Streamline what used to take 20 minutes of tedious manual copying into a 5-second workflow.

Open DevTools & Start

Press F12 on any web page, navigate to the API to Postman panel, and click Start capture. Chrome attaches the debugger cleanly.

02

03

Filter, Redact & Export

Select the requests you want, review the automated credential masking, and download the Postman Collection JSON or sync directly to your workspace.

Frequently Asked Questions

Got questions about how API to Postman works or how your data is handled?

Chrome requires this notification whenever an extension uses the official debugger API to interact with the Chrome DevTools Protocol. This is a standard security banner that guarantees full transparency. The extension only captures network events while you have the capture running.
Yes! By default, the extension scrubs common authentication headers (Authorization, Cookie, X-API-Key) and sensitive JSON payload fields (password, token, secret, otp), replacing them with Postman environment variable templates like {{authorization}}. You can also inspect the collection before downloading.
No. We do not have any remote servers or databases. If you choose to save your Postman API key, it is kept exclusively in your computer's local chrome.storage.local. You can also download the collection JSON without entering any API key at all!
Yes. The extension UI provides checkboxes for individual requests, a "Select visible" toggle, and search/filter controls so you can isolate and export only the specific API calls you care about.
Yes, the complete TypeScript codebase is licensed under the MIT License and hosted on GitHub. Contributions, issues, and audit requests are welcome.
