Hamster is an elegant, minimalist, zero-friction client proofing and presentation tool. Built as a self-contained, offline-first web application, it reimagines image proofing through a unique "one file, two directions" workflow that eliminates subscriptions, user accounts, and external cloud dependencies.Key Features & Workflow Zero-Dependency PortabilityRuns entirely inside any modern web browser as a standalone HTML file. It requires no installation, database, or backend server, making it fast, privacy-focused, and completely functional offline. Creator Layout Canvas Intuitive Drag & Drop: Drop images directly onto an expansive canvas, paste from the clipboard, or load them from local storage. Canvas & Grid Controls: Drag to reposition, scroll to resize, zoom in/out, fit to view, or snap elements to an alignment grid for precise compositions. Typography & Branding: Customize typography, add styled text blocks, select background color tones, or replace the main title with a custom transparent PNG/SVG logo. PDF & HTML Export: Export clean, print-ready PDFs without UI chrome or compile the entire project into a lightweight, shareable single-file HTML document. Seamless Client ProofingWhen the client opens the exported shareable file, almost all editing toolbars disappear, presenting a clean, distraction-free gallery. Clients can move and arrange images, zoom them and minimize them in the sidepanel if needed. Click to mark their preferred images, and the system automatically compiles their selections into a ready-to-send email update. Uncompromising Privacy & Direct File Security Zero Third-Party Middlemen: Eliminates the need for external file transfer platforms (e.g., WeTransfer, Dropbox) or cloud storage services. Direct Local Execution: Images and layout data are embedded directly inside the single HTML file, allowing files to be sent directly as email attachments or private transfers. No Cloud Tracking or Accounts: Operates 100% offline without requiring client logins, user accounts, subscriptions, or external tracking scripts. Complete Data Ownership: Selections and proofing data move directly between creator and client, ensuring client confidentiality and full data privacy. Seamless Website & Workflow Integration Universal Web Compatibility: Built using standard web technologies (HTML, CSS, and JavaScript), making it natively compatible with any web browser or hosting environment. Iframe Embedding: Can be embedded into existing client portals or password-protected pages on any website using a standard <iframe> tag. Zero-Plugin Deployment: Works natively across WordPress, Webflow, Squarespace, Wix, or custom static sites without requiring extra plugins, databases, or server-side scripts.
