HTTP Pass
Read full descriptionHide full description
HTTP Passは、開発者が管理するPreview、Staging、Development環境をiPhone/iPadのSafariで確認するときに使うSafari Web Extensionです。 HTTPSホストごとにBasic Authのユーザー名とパスワードを保存し、SafariからHTTP Passを開いて同期すると、登録済みのホストとパスにだけAuthorizationヘッダーを付与します。 主な機能: - HTTPSホスト単位のプロファイル管理 - パスプレフィックスによる送信範囲の限定 - 認証情報のKeychain保存 - Face IDまたはデバイスパスコード後のパスワード表示 - プロファイルの有効化/無効化 - Safari Declarative Net Requestによるセッションルール同期 HTTP Passは汎用ヘッダー編集ツール、セキュリティ診断ツール、パスワードマネージャーではありません。所有、管理、または検証権限のある開発環境での利用を目的としています。分析SDK、トラッキング、開発者サーバーへの認証情報保存は行いません。
Diff Checker

Compare two versions of any text and see exactly what changed — line by line and word by word, highlighted the instant you paste. Most "spot the difference" attempts end in squinting at two walls of text side by side. DiffCheck does the reading for you: paste an old version and a new one, and every addition turns green, every deletion turns red, so the change jumps out in a second. It works on code, config files, contracts, and plain prose alike — and it never sends a single character off your device. WHAT YOU GET - See every change at a glance — additions in green, deletions in red, nothing missed - Switch between line-level and word-level diffs to catch even a single edited character - Read changes in a clean side-by-side split view that lines the two versions up - Copy a ready-to-use unified patch of any comparison straight to your clipboard - Keep a local history of past comparisons so you can revisit what changed and when - Save reusable snippets and sample diffs to compare the same text again fast PERFECT FOR - Developers reviewing code, pull requests, and config changes on the go - Writers and editors checking edits between two drafts - Legal and business users comparing contract or document revisions - Students learning how diffs and the unified patch format work WHY NOT JUST EYEBALL IT Reading two versions by hand is where mistakes hide — a flipped number, a deleted clause, a changed flag. DiffCheck compares them character by character so you catch the change you would have scrolled right past. PRIVACY Your text never leaves your device. There are no accounts, no servers, and no tracking — every comparison happens fully offline. FULL ACCESS DiffCheck is free to compare text. Full Access unlocks word-level diffs, the side-by-side split view, saved comparison history, and unified patch export.
