Search all of Discogs, sync your vinyl collection, and play albums as you browse.
Sign-up is free, limited to 100 accounts in total. Searching the catalog and syncing your collection, wantlist, and marketplace all require connecting a Discogs account. An account that never connects Discogs is automatically deleted after 6 weeks of inactivity, which frees its spot. Details in the Privacy Policy and Terms.

How SeaDisco Works
A guided tour of every feature. Skim the headings or read top-to-bottom — both work.
Searching Discogs
Search the entire Discogs database by artist, album, label, or any combination. Click Advanced for targeted fields (Artist, Release, Label, Year, Genre/Style, Format, Country). Narrow by type — Masters (every pressing grouped), Releases (individual pressings), or Masters+ (masters plus standalone releases that have no master grouping — useful for finding obscure pressings alongside grouped editions). Sort by relevance, year, title, or label.
Hide owned removes synced collection items from results so you only see new finds.
Hard to Find Mode & No-CDs Toggle
In the Advanced panel, the Hard to find checkbox biases the search toward physical, pre-streaming-era masters: blank Format defaults to Vinyl, blank Year defaults to 1900–1985, sort defaults to least-owned first. Each filter you set explicitly still wins — Hard to find only fills in blanks. Cards in the result grid that don't have any embedded YouTube videos or user-contributed ones get a small purple 🎵 in the corner so you can spot albums where the community could fill the gap.
Next to it, the small CD icon with a red strike 💿 excludes CD-family and digital-only formats (CD, CDr, SACD, DVD, File, MP3, FLAC, AAC, USB, streaming, etc.). Useful when you want strictly analog/vinyl-era pressings — anything that's likely on Spotify gets dropped from the visible results. Both toggles re-filter the cached results instantly without re-querying.
Album Popups
Click any card for full details: tracklist with YouTube previews, version finder, pressing info, credits, photos, and marketplace stats. From the detail popup you can add/remove from collection or wantlist, rate releases 1–5 stars (rating syncs to Discogs), and ★ favorite the album.
The tracklist is collapsible (setting saved across sessions) with an inline track filter. Credits are filterable too — useful for releases with long personnel lists. Master release popups show all pressings with format and country filter pills (selections persist across popups). If a release belongs to a series, the series name is clickable — browse all releases in the series with collection/wantlist badges so you can see what you own and what's missing.
Marketplace stats show lowest price, number for sale, and community want/have counts. Click (est) for condition-based price estimates from Good through Mint, color-coded by grade. The "Sell this release" shortcut appears on releases you already own.
Click an artist, label, or track name in any popup for the unified Lookup menu — search across SeaDisco, your collection, Wikipedia, the Library of Congress, and YouTube without leaving the modal.
Card Badges
Every album card shows quick-action badges — small color-coded vinyl icons for collection, wantlist, and favorite. Active badges are bright; inactive ones appear dimmed. Click any badge to add/remove directly without opening the popup. If an item is in your lists or inventory, those icons appear too. Multiple owned copies show a (N) badge in the corner — click to pick an instance.
Music Player & Queue
▶ on any track plays it via a docked mini-player at the bottom of the screen. Tracks are streamed from YouTube (when matched) or the Library of Congress's public-domain archive. Click the disc icon in the bar to re-open the album popup for whatever's currently playing. The bar persists across page navigation, so you can browse other albums while a track keeps playing.
A cross-source play queue handles YouTube and LOC tracks together. The ＋ button on any track row, LOC item, or Archive item adds it to the queue tail. The ▶ button on a tracklist heading plays the first track and queues the whole album. Open the queue drawer (queue button in the bar) to drag-rearrange rows, jump to any track, or remove individual items. The queue auto-advances as tracks end and pulls fresh tracks across YouTube ↔ LOC seamlessly.
On mobile the player surfaces in your OS lock-screen / Bluetooth controls (play/pause/next/previous). Track URLs are shareable — the URL updates as the queue advances, so copying the address bar gives the recipient the exact track you're on with the album-context disc icon ready.
Discogs's tracklist sometimes lists tracks but doesn't have a YouTube video on file for them. Signed-in users can fill those gaps. When an album has tracks with no video, its tracklist heading shows a 🎵 N missing link — it opens a popup with a one-click YouTube search for the album. Find the right videos on YouTube, paste their links against the tracks, and your contributions are saved site-wide. The next user who opens that album popup sees your video already wired up to ▶ play and ＋ queue. First-submission-wins — no approval queue.
By default a submission from a release popup applies at master scope (lifts to every pressing of the album) when the master is known. Tracks that have a community contribution show a small 🎵 badge next to the title.
Home Strip
The home page shows a strip of cards under your search bar with several tabs: Recent, Feed (a random sample of vinyl from the catalog), Active (most-opened on SeaDisco in the last 90 days), Played (most YouTube plays in the last 90 days), Rare (early vinyl many collectors want and almost no one owns), and Dig (long-tail vinyl nobody on SeaDisco has opened yet).
Recent is your local browsing history — every album popup you opened, ordered by recency. The × on each card removes it from history. The Clear button wipes everything. History syncs across devices when signed in.
The strip has a filter input and a sort dropdown (Opened, Year, Title, Artist).
Companion Tabs
SeaDisco includes dedicated views for adjacent music data:
Library of Congress — search the LOC's public-domain audio archive (early jazz, blues, folk, spoken word). Save items to a personal Saved tab. Playable inline via the cross-source queue.
Wikipedia — search Wikipedia for artists, albums, labels, genres. Save articles. The lookup popup on any artist/label name in an album popup links here in one click.
Archive.org — curated live show recordings (jazz, blues, folk). Save individual shows. Playable inline.
My Records
Connect your Discogs account via OAuth (one-click authorization) to sync your full collection, wantlist, inventory, and lists — any size. Sync runs in the background: your collection and wantlist refresh automatically about every 6 hours for active accounts (less often the longer an account sits idle), and inventory, lists, and orders refresh once daily.
The Collection and Wantlist tabs have dedicated filters (artist, release, label, year, genre, style, format) with + (AND), | (OR), and - (exclude) operators. Collection and wantlist badges on every card show what's in your library.
The Inventory tab shows your marketplace listings with full create/edit/delete support — list a new record for sale, change prices, update conditions, or pull a listing. The editor pulls Discogs' median/low/high price suggestions so you can price with confidence. Each card shows ✏️ edit and 🗑 delete; every release popup for records you own gains a "Sell this release" shortcut.
Lists displays your curated Discogs lists — click any list to browse its items as album cards. Lists are read-only (Discogs's API doesn't expose writes) and sync once daily.
Favorites shows everything you've ★'d. Favorites are SeaDisco-only (not synced to Discogs) and work for releases, masters, artists, and labels.
Multiple Copies & Folders
Own multiple copies of the same release? SeaDisco tracks each copy separately. Cards show a small (N) badge when you own more than one — click it to pick an instance, and the popup scopes its rating, folder, and notes to that specific copy.
Click 📁 above the Collection filters to manage your Discogs folders — create, rename, or delete folders, and bulk-move items between them. All folder changes sync back to Discogs in real time.
Seller Orders
If you sell on the Discogs marketplace, the Account page shows a Seller Orders panel with every open and recent order. Filter by status, search by buyer or release title, and open any order for full details — items, shipping address, buyer info, and the full message thread. Advance the status through Discogs' seller state machine (New Order → Payment Received → Shipped, etc.) and reply to buyers inline with the 💬 quick-reply composer, or open the detail modal for longer messages. A badge on the section header shows how many orders have unread activity since you last looked.
Offline Access
From the Account page, opt in to offline access. Your library (collection, wantlist, favorites, lists, inventory, and cover thumbnails) is cached to your browser's IndexedDB and Cache Storage. Reload while offline and the site boots from cache so you can browse and search your records without a connection. Playback still requires the network. Disabling the toggle wipes the local cache.
Saved Searches
Save any search and re-run it with one click. Saved searches persist across sessions and sync to your account.
Account & Feedback
The Account page handles your Discogs OAuth connection, sync status, offline-access toggle, and account deletion. The "Send feedback" button at the bottom sends your message straight to the admin.
Privacy Policy
Last updated: September 18, 2026
What We Collect
When you create an account, we store your email address (provided by our authentication provider, Clerk) and, if you connect your Discogs account, the OAuth access credentials returned by Discogs.
When you sync your Discogs account, we store a local copy of your collection, wantlist, marketplace inventory (listings), list metadata, list items, and — if you sell on Discogs — your seller order history including buyer usernames, shipping addresses, order items, totals, and the full message thread for each order. This includes per-copy metadata for your collection items (folder assignment, rating, instance notes, and date added) so that multiple owned copies of the same release can be tracked independently. We also cache your Discogs profile information (username, avatar, location, marketplace currency, and account stats including seller/buyer ratings) for display on the Account page.
If you favorite albums, artists, or labels, those selections and their display data (title, artwork URL, type) are stored with your account. If you save searches, those search parameters are stored with your account. If you submit feedback, your email and message are stored.
We store a small set of cross-device preferences (e.g. whether you've enabled offline access) so your settings follow you when you sign in on another device.
We log API usage for operational monitoring. Your IP address is used for rate limiting both anonymous and signed-in users but is not persisted to the database. Google Analytics receives search terms you enter along with standard page view data.
Offline Access (Opt-In)
If you turn on offline access from the Account page, your browser downloads a copy of your collection, wantlist, favorites, lists, inventory, and cover thumbnails into your browser's IndexedDB and Cache Storage. This data lives only on the device you enabled it on; it isn't transmitted anywhere. Disabling offline access (or clearing your browser storage) wipes the local copy. The download itself is opt-in — nothing is cached on your device until you toggle it on.
Third-Party Services
SeaDisco integrates with the following third-party services:
Discogs — music database searches, collection syncing, and collection actions, using your OAuth authorization
Clerk — authentication and account management
YouTube API Services — SeaDisco uses the YouTube API Services (operated by Google) to search YouTube, fetch video metadata (title, channel, duration, thumbnails), and embed playback. When you play, search, or submit YouTube videos from SeaDisco, your interactions are subject to the YouTube Terms of Service and the Google Privacy Policy. You can revoke the YouTube API Services' access to your data at any time via the Google security settings page.
Google Analytics — usage statistics including search terms to help us improve the site. Subject to the Google Privacy Policy.
OAuth Authorization
If you connect via OAuth, SeaDisco receives access to your Discogs account through the standard OAuth 1.0a flow. We store the resulting access token and secret to make API requests on your behalf. We do not receive or store your Discogs password. You can disconnect OAuth at any time from the Account page, which immediately revokes our access.
When connected, SeaDisco can read your collection, wantlist, lists, marketplace inventory, and orders, and — only when you explicitly trigger an action in the UI — create, edit, or delete marketplace listings, change folder assignments, ratings, and notes, and send messages to buyers. Every write goes to Discogs at the moment you click; nothing is queued or scheduled.
How We Use Your Data
Your Discogs OAuth credentials are used solely to make API requests to Discogs on your behalf — searching, syncing your collection, managing your collection/wantlist, creating and editing marketplace listings, and updating seller orders and messages. Every write action (rating a release, moving a folder, editing a listing, changing an order's status, sending a reply to a buyer) is only sent to Discogs when you explicitly trigger it in the UI. We never share your credentials with any other service or third party. Your collection data, inventory, orders, and favorites are used only to display your records and personalize your experience within SeaDisco.
We do not sell, rent, or share your personal data with anyone.
Data Storage & Security
All data is stored in a secured PostgreSQL database hosted on Railway. Your Discogs OAuth credentials are encrypted by SeaDisco before they are stored, and the key is kept outside the database. OAuth secrets are stored server-side only and are never exposed to the browser. Access to the database is restricted to the application server only.
Data Retention & Deletion
Synced user data (collection, wantlist, marketplace inventory, lists, list items, seller orders, order messages, and cached profile) is automatically deleted 30 days after it was last synced, or immediately on request. Your authentication tokens are retained for as long as your account exists.
SeaDisco is limited to 100 accounts in total, whether or not they are connected to Discogs. An account that signs up and never connects Discogs is automatically deleted after 6 weeks (42 days) of inactivity, which frees its spot for someone else. That deletes the login and email along with anything saved to the account (favorites, playlists, play queue, saved searches). Connected accounts are not deleted for inactivity — their cached library data may be pruned per the 30-day retention window above and re-syncs from Discogs on demand the next time you use the site.
Temporary operational data is also pruned automatically: API logs and search caches.
You can delete your account at any time from the Account tab. Deleting your account permanently removes all of your data from our database, including your email, Discogs credentials, collection, wantlist, marketplace inventory, lists, list items, seller orders, order messages, favorites, saved searches, feedback, and profile data. Your Clerk authentication account is also deleted. This action is immediate and irreversible — there is no way to recover your data after deletion. Note that deleting your SeaDisco account does not alter anything on Discogs itself — your Discogs account, listings, and orders are untouched.
Cookies & Local Storage
SeaDisco uses cookies for authentication (via Clerk), analytics (via Google Analytics), and a temporary CSRF protection cookie during the Discogs OAuth flow. We do not use advertising or tracking cookies, and we do not sell any data.
Your browser's localStorage is used for non-sensitive UI state (theme, recently viewed cards, filter and sort preferences, the offline-access toggle). If you opt in to offline access, your library is also stored in your browser's IndexedDB and Cache Storage on that device only. Clearing browser data wipes all of it.

Terms of Service
Last updated: September 18, 2026
Acceptance
By using SeaDisco, you agree to these terms. If you don't agree, please don't use the site.
SeaDisco integrates the YouTube API Services for video search, playback, and metadata. By using SeaDisco you also agree to be bound by the YouTube Terms of Service.
What SeaDisco Is
SeaDisco is a music discovery tool that searches the Discogs database (including Masters+ mode for finding orphan releases) and helps you browse and manage your vinyl collection, wantlist, favorites, lists, marketplace inventory, and seller orders. It is a personal project provided as-is.
Account Access
SeaDisco is open to public sign-ups via Clerk authentication. Searching the Discogs catalog and the personal features (collection sync, wantlist sync, marketplace listing management) all require connecting your Discogs account via OAuth — a signed-in account that hasn't connected Discogs can use the home strips, the Library of Congress, Wikipedia and Archive.org views, and save favorites, playlists and a play queue. SeaDisco is limited to 100 accounts in total, connected or not. When that limit is reached, new sign-ups are closed until a spot opens. To keep spots available, an account that signs up but never connects Discogs is treated as an abandoned login: if it goes 6 weeks (42 days) with no activity and still has no Discogs connection, it is automatically deleted. This removes the Clerk login and anything saved to the account, such as favorites, playlists and the play queue. Connected accounts are not deleted for inactivity — their cached collection / wantlist / inventory / order data may be pruned by routine cleanup after about a month of not syncing, but it re-syncs from Discogs automatically the next time you use the site. If you want to leave permanently, use the Delete Account button on the Account page — that erases all of your data immediately and irreversibly.
We reserve the right to suspend or remove accounts at our sole discretion, with or without notice, particularly for abuse, automated scraping, or violations of these terms or Discogs' own terms of service.
Marketplace Actions
When you use SeaDisco to create, edit, or delete a Discogs marketplace listing, to change the status of a seller order, or to send a message to a buyer, those actions are forwarded to Discogs and take effect immediately on your Discogs account. You are solely responsible for the listings you publish, the prices and conditions you set, the order statuses you change, and the messages you send. SeaDisco is a convenience interface to the Discogs marketplace — Discogs' own Seller Terms, fees, and refund/cancellation policies still apply, and your obligations to buyers are governed entirely by your agreement with Discogs.
SeaDisco does not facilitate payments, hold funds, arbitrate disputes, or guarantee the accuracy of Discogs' price suggestions. Price suggestions shown in the listing editor come directly from Discogs and are provided for reference only.
Your Account
You are responsible for keeping your SeaDisco account secure. SeaDisco uses your Discogs OAuth credentials only to interact with the Discogs API on your behalf, and you can disconnect at any time from the Account page.
Acceptable Use
Don't abuse the service. This includes but is not limited to:
Automated scraping or excessive API usage beyond normal browsing
Attempting to access other users' data
Using the service to violate Discogs' own terms of service
SeaDisco rate-limits requests per IP address to prevent abuse and to stay within the upstream API quotas (Discogs, YouTube, Library of Congress, archive.org). If you hit a limit, the affected feature will return an error for a short window and then recover; please don't retry in a tight loop.
Third-Party Content
Search results, album artwork, and audio streams are sourced from third parties — Discogs (release data + cover art), Library of Congress + Internet Archive (audio + metadata), Wikipedia (articles), YouTube (video search + playback). Cover art remains subject to Discogs' licensing terms. SeaDisco does not own or control any of this content. All trademarks and copyrights belong to their respective owners.
Availability & Warranty
SeaDisco is a personal project, provided "as is" without warranties of any kind. There is no SLA, no uptime guarantee, and no commitment that any feature will keep working or that the service will keep running. Features may be added, changed, or removed; the service may go offline temporarily or permanently with little or no notice. Account deletion — whether you delete your own account, or an unconnected account is removed after 6 weeks of inactivity — results in data loss, and routine cleanup can prune cached library data; keep your own backup of anything you can't lose.
Limitation of Liability
SeaDisco and its operators are not liable for any damages arising from your use of the service, including but not limited to lost data, missed events, or inaccurate pricing information.
Changes to These Terms
We may update these terms from time to time. Continued use of SeaDisco after changes constitutes acceptance of the new terms.
