Proxygen 5.3 is now available with client app based request matching in rewrites and scripting. This update fixes the janky table scrolling that’s been there since Tahoe. You also have keyboard shortcuts to zoom in and out editor font size! Download at proxygen.app

Proxygen 5.1 is now available with MCP support. It’s not just programmatic access to the app’s model layer. Whatever the agent does via MCP tools is visible in the app UI for you to review and continue from. This changes what the app is, in a profound way. Download at proxygen.app

Proxygen for iOS v4.5 comes with a new tunneling engine that ensures no traffic leaves your device without the proxy seeing it. There’s a custom TCP/IP stack and a traffic classifier. It now also shows SSE events and has DNS override. It’s a one-time $10 purchase ✌️ apps.apple.com/fi/app/proxy...

Proxygen v4.5.0 now comes with scripting support in Mac and iOS apps. Write JavaScript code to modify HTTP traffic. It’s pretty great! Get the app 50% off for a limited time at proxygen.app (the website also got a refresh)

@gatestone.bsky.social Muistelen että joskus 15 vuotta sitten lyötiin vetoa kumpi tulee ennen, Golla iOS appien vai Swiftillä Android appien kirjoittaminen. Me tehtiin siinä se virhe ettei speksattu tarpeeksi tarkkaan mitä kysymys tarkoitti. Esim. käytän nyt jo Go paketteja osana iPhone appejani.

Google Play store doesn’t allow apps that support older Android versions and kicked my Beacon app out. So I built an APK and made it available as a direct download at freshbits.fi/apps/beacon/. This works on Android as old as 5.0 Lollipop with 2.7” QVGA screens. Basically runs on anything 👍
Beacon app installed on a rugged small sized Android device. It allows the GPS position of this device to be tracked in Maptrails app.
