Screen Studio Kit 1.3 helps you design, compare, and export complete app-store screenshot campaigns on macOS and Windows.Create multiple campaign treatments inside one project and compare them before choosing the version to export. Start with any of 20 responsive templates or build a layout from scratch.Edit text directly on the canvas, apply rich typography, and import custom fonts. Use responsive focal crops, feature callouts, reusable background systems, multi-device compositions, stickers, and widgets to keep a visual system consistent across the full screenshot set.One responsive composition adapts across iPhone, iPad, Mac, Apple TV, Vision Pro, Apple Watch, Google Play, and Microsoft Store outputs. Add per-size position, dimension, or visibility overrides only where a layout needs them. Device frames also support live Turn and Tilt controls from -60° to 60°.Localization keeps translated copy and language-specific captures in the same project, with CSV import/export and validation of the language-and-size matrix. Preflight catches missing translations or assets, unsafe bounds, invalid counts, output dimensions, and store-specific format rules before deterministic PNG or JPEG export.Free includes the complete editor, local projects, preview, validation, device-frame editing, one size and one language per export, and up to 10 full-resolution exports per local day. A one-time Pro purchase unlocks unlimited multi-size and multi-language export, all templates, the complete element library, localization CSV workflows, automated capture in direct-distribution builds, and store publishing.Available from the Mac App Store and Microsoft Store.

Diff Anything is a local-first desktop comparison app for macOS and Windows. Compare spreadsheet data across XLSX, ODS, Apple Numbers, CSV, and TSV files without converting formats first. It compares stored cell values, so you can focus on the data even when the source formats differ.For folders, use a two-pane review with search, filters, moved-file detection, ignore rules, and safer synchronization plans. PDF comparison gives you two explicit choices: visual page diff for changes to charts, images, signatures, stamps, and layout; or extracted-text diff for wording changes.Text, JSON, source code, images, directories, and more use purpose-built comparison views. CLI and Git difftool modes bring the same workflow to scripts and source control. Files stay on your computer: no accounts, uploads, cloud comparison, analytics, or telemetry.

DevDock is a local-first Windows workspace for operating software projects without rebuilding context every time you switch. It keeps project folders, saved commands, Docker environments, Git state, run history, health checks, database operations, and security audits together in one desktop app.Version 1.1 adds a system-wide Ctrl+Shift+K launcher, so you can search and run safe project commands without first opening the main window. A system-tray companion shows active and recent runs plus actions pinned to Today. DevDock can also discover repository-defined Laravel Artisan, Symfony Console, CodeIgniter Spark, Django management, and Rails Rake commands without booting the framework or executing project code. Structured run-time inputs and named presets make variable commands repeatable.Git workflows remain explicit and inspectable. You can review changed files and textual diffs before a commit, manage remotes with embedded credentials redacted, and switch branches from the project header. Commands that require values, custom shell execution, destructive or production confirmation, or Git push still open the appropriate review step.A project can represent one repository, a monorepo, or several separately located folders. Each folder keeps its own detection, working directory, generated tasks, and shortcuts. Today collects recent projects and pinned daily workflows, while command history retains the target, timing, exit state, and output of each run.Database tools cover schema inspection, constrained read-only record lookups, counts, migration review, diagnostics, and confirmed backup operations for SQLite, MySQL/MariaDB, and PostgreSQL. The local, read-only security audit checks registered folders for exposed secrets, private keys, tracked credential files, unsafe permissions, escaping symlinks, and missing lockfiles. Source code is not uploaded, and matched secret values are withheld.DevDock is available through the Microsoft Store. The free tier supports up to three local projects with core commands, Git, Docker, Project Doctor, and security audits. A one-time Pro purchase unlocks unlimited and multi-folder projects, custom workflows, full history and insights, database tools, SSH transfers, and configuration backup and restore.
