API Key Manager

Read full description

API Manager helps you organize the sensitive details behind your projects in one clean, fast vault. Keep API keys, environment variables, server access, and recovery codes grouped by provider and project so you can find what you need in seconds. NEW: WORKS WITH CODESHELL Open any server you save in API Manager in CodeShell, the SSH terminal with on-device Apple Intelligence, in one tap. The host, user, port, password and SSH key go across for you, through your device's keychain and never in a link, so there's nothing to copy or retype. Saved a server in CodeShell first? Send it to API Manager to keep it with the rest of your credentials. Requires CodeShell 1.5 or later. Built for developers, founders, and operators, API Manager makes it easier to manage: • API keys and service credentials • Environment variables for apps and deployments • Server and VPS access details • Recovery keys and backup codes Why people use API Manager: • Organize secrets by service, provider, and project • Open the right credential quickly with a simple, focused interface • Open saved servers in CodeShell in one tap • Copy important details fast when configuring, deploying, or debugging • Keep sensitive information behind an authentication-locked vault • Reduce the chaos of scattered notes, screenshots, and text files Whether you are switching between AI providers, cloud servers, personal accounts, or recovery items, API Manager gives you one reliable place to keep everything organized and ready when you need it.

About

Slipstream File Transfer

Features
Read full description

Slipstream is technically the fastest way to move big files between iPhone, iPad and Mac. Every other way uses one connection. Slipstream uses a cable and a direct wireless link at the same time, so the two speeds add up. WHY IT'S FAST • Two connections, one transfer. A USB cable and a direct wireless link carry the same file together. • In our tests, a 10 GB file went from iPhone to iPad in 1:23, at about 120 MB/s: 40 MB/s over the cable plus 80 MB/s over wireless. That's about 1.5Ɨ faster than wireless alone (AirDrop took 2:05) and about 3Ɨ faster than a USB cable alone (4:10). • These are our own measurements. Your speeds will vary with the device model, the condition of the devices, the cable and the wireless surroundings. • Unplug anytime. If one connection drops, the other one finishes the job. EASY TO USE • Open Slipstream on both devices. They find each other automatically. • Plug in a cable for extra speed, or send over wireless alone. • Tap the circle, pick your files and accept on the other side. On a Mac, just drag files onto the circle. • On iPhone and iPad, received files go to the Slipstream folder in the Files app. SAFE, START TO FINISH • Files go straight from one device to the other, never through a server or the cloud. • Every transfer is end-to-end encrypted with a fresh key. • No account, no sign-in, no tracking. Works between iPhone, iPad and Mac, in any direction.
