Written by The Axio Leads team 5 min read
In addition to direct web store installation, users can install the Axio Leads extension manually by sideloading the unpacked ZIP archive. Sideloading guarantees that you always run the latest feature releases without waiting for web store review queues, allows unmetered local scraping performance, and ensures 100% data privacy with all operations executing directly in your local browser sandbox. Here is the complete 5-step walkthrough with HD screenshots.
Key takeaways
- The axio-leads.zip installation package is lightweight (~1.2 MB), strictly Manifest V3 compliant, and 100% clean verified code.
- Requires only toggling Developer mode on any Chromium-based browser (Chrome, Edge, Brave, Coc Coc).
- Always extract the ZIP archive first and select the primary directory containing manifest.json directly.
- Once loaded, the extension automatically attaches an interactive Radar scraping toolbar whenever you navigate to google.com/maps.

Step 5: Pin the extension and start scraping on Google Maps
For fast daily access, click the Puzzle icon (🧩 Extensions) on your browser's top navigation bar, locate Axio Leads, and click the Pin (📌) icon so that the green radar logo remains permanently visible next to your address bar.
Now, open a new tab and visit google.com/maps. Search for any business type in any city or neighborhood (e.g. "Dentists in Dallas" or "Marketing Agencies in London"). The Axio Leads floating Radar scanner will automatically appear on the viewport, allowing you to scrape contact details, filter mobile numbers, and export cleanly formatted Excel spreadsheets in 1 click!
Troubleshooting Common Sideloading Issues
If you encounter an issue during manual installation, check these quick solutions:

manifest.json. Open the folder in file explorer and ensuremanifest.jsonis located at the root level of the folder you select. - "Load unpacked" button is missing: Double-check the top-right corner of
chrome://extensionsto confirm that the Developer mode switch is toggled ON (blue). - How to update to a newer version: When a new update is released, simply download the new zip file, extract and overwrite the existing files in your folder, then click the Reload (circular arrow) button on the Axio Leads extension card.
