Eagle vs Billfish: Asset Managers for Windows Designers

Eagle and Billfish are both desktop libraries for collecting, tagging and searching design references and assets on Windows. Eagle is a paid one-time purchase with a 30-day trial, and adds a font manager, AI search and a plugin ecosystem. Billfish is free, comes from a Chinese developer (its website and help center are in Chinese), and covers folders, tags, color filters and an optional cloud library. If you want font management and English documentation, start with Eagle's trial; if cost matters most, try Billfish first. It can import an existing Eagle library, so you can test it on your real collection.

Eagle vs Billfish at a glance

All details come from each vendor's own site, checked October 2026. Both products update often, so confirm anything you depend on before buying or migrating.

Eagle in more detail

Eagle positions itself as an asset manager for designers. Its browser extension can drag-save images, batch-save every image on a page (with size and format filters, and folders and tags applied as you collect), and take screenshots. Inside the app, smart folders sort items automatically by name, tag, color or format, and you can annotate images, rate them and find duplicates.

Eagle's site says it can import any file format. It previews video and GIFs, plays common audio formats (MP3, WAV, AAC, FLAC, M4A), saves web and video bookmarks, and has a font manager that previews and categorizes font files without installing them. Recent versions add AI search (visual and semantic), rule-based AI actions for tagging and renaming, and plugins such as a background remover.

Pricing is a one-time licence rather than a subscription, with a 30-day full-feature trial.

Billfish in more detail

Billfish, made by Suzhou Changzuiyu Software (苏州长嘴鱼软件有限公司), describes itself as a free asset management tool for designers. Its help center shows a familiar layout: a left sidebar with a folder tree and tag system, a filter bar, and a right panel where you add tags, notes and ratings and extract color values from an image.

You can add assets by importing local folders or files, dragging them into the window, or copying files in Explorer and pressing Ctrl+V in Billfish. It also imports Eagle libraries and packages, and has a browser extension for collecting images from the web. The optional cloud library adds encrypted backup, use across several devices, and share links that can be password protected.

The main drawback for English-speaking teams is documentation: the official site and help center are in Chinese.

Which one should you pick?

• Pick Eagle if you manage fonts alongside images, want English documentation, or plan to use its AI search and plugins.
• Pick Billfish if you want a capable free library, mostly organize images by folder, tag and color, and don't mind Chinese-language help.
• Pick neither if your assets are mostly brand kits used in Adobe apps. Creative Cloud Libraries hold color palettes, character styles, logos and graphics (up to 10,000 assets per library) and appear inside Photoshop, Illustrator and InDesign; Creative Cloud Libraries or a local clip shelf? compares that approach.

If what you need is a board to look at while you work rather than a searchable library, PureRef is the better fit.

Where clipboard history fits

An asset manager and clipboard history do different jobs. Windows clipboard history (Win+V) keeps your last 25 text, HTML or bitmap items, has no tags or folders, doesn't store files, and clears unpinned items when the PC restarts. It's for moving something you copied a moment ago, not for finding it next year.

The two meet at capture time. Eagle can collect from the clipboard, and Billfish accepts copied files with Ctrl+V, so copying is often the quickest way in. A clipboard shelf such as Edge Drop keeps the images and files you copied during a session and lets you drag them into either library afterwards, which suits people who collect first and file later.

Whatever you collect, the library isn't a licence. How to collect UI inspiration screenshots legally covers what you can keep and reuse.
