A fast, native desktop viewer for e621 and e6ai.
Browse in a small, focused window — no web browser, no ads, and your account credentials stay in your computer's secure password store. Switch between e621 and e6ai from the header; each site keeps its own search, account, and favorites.
- Browse e621 and e6ai, switchable from the header with independent state per site
- Quick tag search with autocomplete and search history
- Full-resolution viewer for images, GIFs, and videos
- Sign in with your e621 or e6ai account to favorite, comment, and edit tags (a separate account per site)
- One-click downloads with a customizable filename
- Per-app VPN to bypass regional blocks — sign in with just a Mullvad account number (or import any WireGuard config); only Clowder's traffic is tunneled, no system-wide changes, no admin required
- Keyboard shortcuts throughout
- Light and dark themes

If e621 or e6ai is blocked in your country, Clowder can route its own traffic only through a WireGuard peer — the rest of your system keeps using your normal connection.
With a Mullvad account (easiest):
- Open Settings → VPN and enter your 16-digit Mullvad account number, then hit Sign in.
- Pick a country and city where the site is reachable from the dropdowns.
- Hit Connect. The tunnel auto-starts on subsequent launches and is treated as connected only after the WireGuard handshake completes.
Clowder generates a WireGuard key, registers it as a device on your account, and picks a server for you. Mullvad accounts allow up to 5 devices at the time of writing; Sign out removes Clowder's device again.
With any other provider:
Under Settings → VPN → use a custom WireGuard config, import a .conf
file exported from your provider (Proton, IVPN, a self-hosted peer, …).
⚠️ Don't run a system-wide VPN at the same time. If your OS-level Mullvad/WireGuard app (or another full-tunnel VPN) is connected, Clowder's tunnel gets nested inside it and the connection breaks — sign-in and browsing will fail. Use one or the other, not both.
Your account number and private key are stored in your OS keychain (Keychain on macOS, Credential Manager on Windows, Secret Service on Linux). DNS is resolved inside the tunnel to prevent leaks. Note that hostnames are resolved over IPv4 (A records) only. DNS answers are cached briefly inside the app so many simultaneous media requests for the same host do not repeat the same lookup.
Requires Node.js 24+, Rust, and the platform dependencies for Tauri 2.
