About

Byoky

Features
Read full description

Byoky is a wallet for your AI API keys. Keep your OpenAI, Anthropic, Gemini and other AI keys in one encrypted wallet on your iPhone or iPad. Apps connect to the wallet, you approve, and Byoky makes the API calls for them. The app never sees your key. WORKS IN SAFARI The Byoky Safari extension brings the wallet to Safari. Add keys in its popup, and websites that support Byoky can use them, just like the desktop extension. BUILT-IN BROWSER Open any web app inside Byoky by its address. It connects to your wallet automatically, with no extension needed. ONE WALLET, EVERY PROVIDER Anthropic (API keys and Claude setup tokens), OpenAI, Google Gemini, Mistral, Cohere, xAI, DeepSeek, Perplexity, Groq, Together AI, Fireworks, OpenRouter, Azure OpenAI and custom endpoints. YOU STAY IN CONTROL β€’ Approve every app before it connects. β€’ See every request and token count. β€’ Set allowances, and revoke access any time. β€’ Groups and cross-provider routing: move an app from Claude to GPT without the app changing a line. NO SERVERS No account. No cloud. No tracking. Keys are encrypted and stored in the iOS Keychain. Requests go straight from your phone to the provider. Move keys between devices with password-protected .byoky backup files. OPEN SOURCE MIT-licensed on GitHub: github.com/MichaelLod/byoky

S3Deck puts AWS S3 and every S3-compatible storage on your iPhone β€” Cloudflare R2, MinIO, Backblaze B2, DigitalOcean Spaces, Wasabi, Ceph and any custom endpoint. Check a bucket, grab a file, share a link or fix a bucket setting without opening a web console. BROWSE AND PREVIEW β€’ Folders and files laid out for the phone: tap to open, long-press to select several, β‹― for every action. β€’ Preview photos, PDFs, video, audio and text right in the app. β€’ Filter a folder instantly, or search a whole bucket. UPLOAD AND DOWNLOAD β€’ Upload from the Files app, iCloud Drive or any file provider. β€’ Downloads land in S3Deck's own folder, which you also find in the Files app under On My iPhone. β€’ A live transfer queue with retry and cancel; large files go up in parts. MANAGE OBJECTS β€’ Create folders, rename, copy, move and delete. β€’ Edit metadata and headers, tags, storage class and permissions; browse and restore versions. SHARE IN A TAP β€’ Presigned links with an expiry, public/private toggles and copy-ready object URLs. β€’ Open downloaded files in other apps through the share sheet. BUCKET SETTINGS β€’ Bucket policy editor with validation and ready-made snippets. β€’ CORS rules, lifecycle rules, versioning, ACLs and access logging. PRIVATE BY DESIGN β€’ S3Deck connects directly from your iPhone to your storage endpoint. Your files and credentials never pass through any server of ours β€” there isn't one. β€’ Secret keys are kept in the iOS Keychain. β€’ Mark production connections read-only to block every delete and overwrite. β€’ No analytics, no tracking, no account. Works with the same connections as S3Deck for Mac, Windows and Linux. Available in English and Vietnamese.
