Media Grab | Flutter Social Media Video and Audio Downloader

This app requires a download engine you host yourself. Choose either path: a self-hosted Cobalt instance for the simplest direct setup, or the included Node.js backend, which can be configured to route through Cobalt, TikWM, yt-dlp, or any mix of the three. Neither is included in this purchase — either way you will need your own VPS or server to run it, at your own recurring cost. No API keys, servers, or hosting are provided with this item.

Media Grab is a complete Flutter Android app for downloading video and audio from Instagram, TikTok, Facebook, X/Twitter, Pinterest, Reddit, Snapchat, Vimeo, Dailymotion and more — built with a self-hosted download engine (direct Cobalt, or the included multi-engine Node backend — your choice), server-verified subscriptions, AdMob monetization and full localization in 18 languages.

Most downloader templates hard-code the seller’s own API keys into the app. Anyone who unzips the APK gets them, the seller pays for every buyer’s traffic, and the day the seller shuts the service off, every buyer’s app stops working.

Media Grab does not work that way. The app ships with no third-party API keys at all. Connect it directly to your own self-hosted Cobalt v11 instance for the simplest setup, or deploy the included Node.js backend, which can run Cobalt, TikWM, yt-dlp, or any mix you configure — including entirely without Cobalt — plus multiple fallback engines and server-side purchase verification when you need them.

App features

• Downloads from Instagram, TikTok, Facebook, X/Twitter, Pinterest, Reddit, Snapchat, Vimeo, Dailymotion and more
• Video and audio-only downloads, with capability-aware quality selection up to 4K when the engine and source support it
• Available in 18 languages — including right-to-left Urdu, Arabic and Persian
• Light and dark themes
• Share-sheet import, clipboard link detection, in-app media player, download history
• Clean Material 3 interface built with Flutter

Backend included

• Direct Cobalt v11 mode — no API key and no Node proxy required for the simplest setup
• Four download engines available: Cobalt, RapidAPI, TikWM and yt-dlp, with configurable routing and fallback
• HMAC-signed requests, rate limiting and boot-time configuration validation
• Docker, docker-compose, PM2 and nginx deployment recipes included
• A one-command smoke test to verify every deployment

Monetization

• AdMob banner, interstitial and rewarded ads
• Google Play subscriptions — monthly, 6-month and yearly plans
• Server-side purchase verification: premium access is granted only after Google confirms the purchase, and Firestore security rules prevent any client from writing the entitlement itself

Built to be rebranded

• One single configuration file drives the app name, package ID, brand colors, support email, legal URLs, ad unit IDs and subscription product IDs
• One command renames and rebrands the entire project, including the Android package structure
• A packaging script that scans for secrets before every build, so nothing of the previous owner’s ever ships by accident
