Instagram does not natively allow downloading of photos, videos, reels, or stories. This extension provides a one-click solution to save Instagram media to the user's local device.

1. User installs extension and browses Instagram. 2. injects.js uses MutationObserver to detect page navigation and extract media shortcodes from the DOM. 3. Content script adds download UI controls to Instagram posts/stories. 4. When user clicks download, inject.js dispatches custom events that trigger tel_download_video() to fetch media via chunked range requests. 5. Downloaded blobs are concatenated and saved locally via anchor element click.

Target users: Instagram users who want to save media for offline viewing / Content creators who want to repost or archive Instagram content / Social media managers collecting reference content

content-script.js is heavily minified (102KB) making full logic inspection difficult
Remote config endpoint (scrm-data-us-oss.oss-us-west-1.aliyuncs.com/sp-plus/settings) could theoretically control feature gating server-side but no evidence of this in code
price.html exists as an unused Vue template - purpose unclear

Monetization

No paid features detected

Store description explicitly states '100% free for all users'. No matches found for premium, subscribe, payment, upgrade, purchase, price, billing, stripe, plan, vip, unlock, or limit keywords in source code. The 'pro' keyword hits are false positives from minified code (generic variable names in webpack bundles). The 'license' hit is just a MIT License notice. price.html is an empty Vue.js template shell with no pricing logic. No feature gating or payment platform integration code found.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, authentication, or account creation code found in the extension source. The extension operates as content scripts on Instagram pages the user is already browsing; it does not implement its own auth system or redirect to a login flow. The core workflow (detecting and downloading media from visible Instagram pages) works without any extension-specific login.
