-title: Link previews
-desc: How Penpot serves Open Graph metadata for shared links, so that Slack, Discord, Twitter and other platforms render rich previews with the file name and thumbnail.
---
-
-# Link previews
-
-When a user pastes a Penpot link in a chat or social platform (Slack, Discord,
-Twitter/X, WhatsApp, Telegram, LinkedIn, Mastodon, Bluesky...), the platform's
-crawler fetches the URL and looks for [Open Graph](https://ogp.me/) metadata to
-render a rich preview card. This subsystem serves that metadata dynamically:
-
- * For a **file** link: the file name as title and the latest dashboard
-   thumbnail of the file as preview image.
- * For a **project** or **team** link: a generic "Project | Penpot" or
-   "Team dashboard | Penpot" title.
- * In any other case (or when the feature is disabled): the default Penpot
-   title, description and preview image.
-
-The whole feature is gated behind the `link-preview` flag (enabled with
-`enable-link-preview` in `PENPOT_FLAGS`), and is **disabled by default**. See
-[Security considerations](#security-considerations) below for why.
-
-## How it works, end to end
-
-The main obstacle is that Penpot is a SPA and all the routing state lives in
-the URL **fragment** (`#/workspace?file-id=...`). The fragment is never sent to
-the server, so with a plain URL the backend has no way to know which file the
-link points to. The feature is therefore built from three cooperating pieces:
-
-```text
- user shares URL          crawler (Slackbot, ...)            regular browser
-       │                          │                                 │
-       │  https://host/?file-id=X#/workspace?...                    │
-       │                          │                                 │
-       ▼                          ▼                                 ▼
-   [frontend]                 [nginx]                           [nginx]
- mirrors context      user-agent matches crawler        user-agent is normal
- params before the    rewrite / -> /link-preview              serve SPA index.html
- fragment on every    (query string preserved)
- navigation                       │
-                                  ▼
-                             [backend]
-                        GET /link-preview?file-id=X
-                        query DB, render Open
-                        Graph HTML template
-```
-
-### 1. Frontend: mirroring context params on the query string
-
-File: `frontend/src/app/main/router.cljs`
-
-On every navigation, the `navigated` event reads the freshly stored
-`(:route state)` and syncs its `file-id`/`team-id`/`project-id` fragment
-params into the query string (before the fragment) using
-`history.replaceState`. Every other param in the URL is left untouched,
-so unrelated params owned by other code survive. The write is skipped
-when the resulting href already matches the address bar. The backend
-applies its own file > project > team priority, so no filtering happens
-on the frontend. The resulting URLs look like:
-
-```text
-https://design.penpot.app/?file-id=<uuid>#/workspace?team-id=...&file-id=...&page-id=...
-https://design.penpot.app/?team-id=<uuid>&project-id=<uuid>#/dashboard/recent?...
-https://design.penpot.app/?team-id=<uuid>#/dashboard/recent?team-id=...
-```
-
-Routes without any of those ids (e.g. auth pages) clear them from the
-query string; `replaceState` only writes when the computed href differs
-from the current one, so no URL churn happens on navigation.
-
-This way, when the user copies the URL from the address bar and shares it, the
-context ids travel in a part of the URL that *does* reach the server.
-
-Legacy hash routes (`/workspace/:project-id/:file-id`, `/view/:file-id`,
-`/dashboard/team/:team-id/...`) were removed: those old URLs no longer
-redirect and resolve to the not-found page instead.
-
-### 2. Nginx: detecting link preview crawlers
-
-Files: `docker/devenv/files/nginx.conf` (devenv) and
-`docker/images/files/nginx.conf.template` (production image).
-
-A `map` block classifies the request by `User-Agent`:
-
-```nginx
-map $http_user_agent $penpot_link_preview_agent {
-    default 0;
-    ~*(slackbot|discordbot|twitterbot|facebookexternalhit|facebookcatalog|whatsapp|telegrambot|linkedinbot|skypeuripreview|pinterestbot|redditbot|embedly|iframely|mastodon|bluesky|applebot|googlebot|bingbot|bingpreview|duckduckbot) 1;
-}
-```
-
-Inside the SPA root location, crawler requests for `/` are internally
-rewritten to the backend link-preview endpoint (the query string is preserved by
-`rewrite ... last`):
-
-```nginx
-if ($penpot_link_preview_agent) {
-    rewrite ^/$ /link-preview last;
-}
-
-location = /link-preview {
-    proxy_pass http://127.0.0.1:6060/link-preview$is_args$args;   # devenv
-    # proxy_pass $PENPOT_BACKEND_URI/link-preview$is_args$args;   # production template
-}
-```
-
-Regular browsers are not affected: they keep receiving the SPA `index.html`.
-If you self-host behind a different reverse proxy, you need to replicate this
-routing there.
-
-### 3. Backend: the `/link-preview` endpoint
-
-File: `backend/src/app/http/link_preview.clj` (new namespace).
-
-The handler:
-
- 1. If the `link-preview` flag is not set, skips any lookup and uses the
-    default context.
- 2. Otherwise parses `file-id` / `project-id` / `team-id` from the query
-    params. A present `file-id` is decisive: file links never fall through
-    to the project/team card, even when the value is a malformed or unknown
-    id (both yield the generic card); only a missing `file-id` key falls
-    through to project/team.
- 3. For a `file-id`, runs a single query joining `file` with its most recent
-    non-deleted `file_thumbnail` row (the dashboard thumbnail):
-
-    ```sql
-    SELECT f.name, ft.media_id
-      FROM file AS f
-      LEFT JOIN file_thumbnail AS ft
-             ON (ft.file_id = f.id AND ft.deleted_at IS NULL)
-     WHERE f.id = ?
-       AND f.deleted_at IS NULL
-     ORDER BY ft.revn DESC NULLS LAST
-     LIMIT 1
-    ```
-
- 4. Builds the context: `:title` is `"<file name> | Penpot"` and `:image` is
-    `<public-uri>/assets/by-id/<media-id>` when a thumbnail exists. Missing
-    data falls back to the defaults; the default image is
-    `<public-uri>/images/penpot-link-preview.png` (a static asset shipped in
-    `frontend/resources/public/images/`).
- 5. Renders `backend/resources/app/templates/link-preview.tmpl` and responds with
-    `200`, `text/html` and `cache-control: no-store, no-cache, max-age=0`.
-
-The endpoint **always returns 200** with at least the generic metadata; a
-non-existent file id, a malformed id or a disabled flag never produce an
-error, so crawlers always get a valid preview.
-
-The route is registered in `backend/src/app/http.clj` and wired in the
-integrant system map in `backend/src/app/main.clj` (`::http.link-preview/routes`,
-which only needs the `::db/pool` dependency). The route declares
-`:allowed-methods #{:get :head}`, so other methods get a `405` from the shared
-`restrict-methods` middleware.
-
-### The HTML template
-
-File: `backend/resources/app/templates/link-preview.tmpl`.
-
-A minimal HTML page with `og:title`, `og:description`, `og:image`, the
-equivalent `twitter:*` card tags and `<meta name="robots" content="noindex">`.
-The body contains a single script:
-
-```html
-<script>location.replace((location.pathname.replace(/link-preview\/?$/, "") || "/") + location.search + location.hash);</script>
-```
-
-so that if a *human* somehow lands on `/link-preview` (e.g. some clients let users
-click through to the fetched URL), the browser bounces back to the SPA root
-keeping the query string and the fragment, and the app loads normally. The
-redirect strips only the trailing `link-preview` segment so subpath
-deployments keep their prefix. Crawlers do not execute
-JavaScript, so they just read the meta tags.
-
-### Making file thumbnails publicly accessible
-
-File: `backend/src/app/http/assets.clj`.
-
-Crawlers fetch `og:image` anonymously, so the thumbnail asset must be served
-without authentication. The assets handler decides per storage bucket whether
-auth is required; with this feature the `file-thumbnail` bucket is treated as
-public **only while the `link-preview` flag is enabled**:
-
-```clojure
-(defn- public-bucket?
-  [bucket]
-  (or (contains? public-buckets bucket)
-      (and (= "file-thumbnail" bucket)
-           (contains? cf/flags :link-preview))))
-```
-
-With the flag disabled, `file-thumbnail` objects keep requiring an
-authenticated profile with access to the file, as before.
-
-## The feature flag
-
-Defined in `common/src/app/common/flags.cljc` as `:link-preview`, listed in the
-`varia` set and **not** included in the default flags. Enable it on the
-backend with:
-
-```bash
-export PENPOT_FLAGS="$PENPOT_FLAGS enable-link-preview"
-```
-
-It is a backend-only decision point; the frontend URL mirroring is always
-active (it is harmless on its own), and the nginx crawler routing is also
-unconditional — with the flag off the endpoint simply serves the generic
-metadata.
-
-## Security considerations
-
-Enabling `link-preview` deliberately trades some privacy for shareability:
-
- * **File names become readable by anyone who knows the file id** (the
-   `/link-preview` endpoint does no permission check).
- * **Dashboard thumbnails become downloadable by anyone who knows the media
-   id** (the `file-thumbnail` bucket becomes public).
-
-Both ids are random UUIDs, so they are not enumerable, but this is
-knowledge-of-the-id access, not real authorization. This is the standard
-trade-off that link preview features make; it is the reason the flag is off
-by default and should be documented to self-hosters before they enable it.
-
-The preview page also sets `robots: noindex` to keep search engines from
-indexing these preview pages, and responses are marked non-cacheable.
-
-## Testing it locally (devenv)
-
-1. Make sure the devenv nginx picked up the config (restart the devenv, or
-   `nginx -s reload` inside the container, if it predates these changes).
-
-2. The flag already ships enabled in devenv via `backend/scripts/_env`, so
-   no export is needed there; outside devenv, enable it before starting
-   the backend:
-
-   ```bash
-   export PENPOT_FLAGS="$PENPOT_FLAGS enable-link-preview"
-   ```
-
-3. In the browser (`http://localhost:3449`), open a file in the workspace and
-   go back to the dashboard — leaving the workspace is what generates the
-   dashboard thumbnail. Verify the address bar now shows `?file-id=...`
-   before the `#`.
-
-4. Hit the endpoint directly (bypasses the user-agent detection):
-
-   ```bash
-   curl "http://localhost:3449/link-preview?file-id=<FILE_ID>"
-   ```
-
-   Expect HTML with `og:title` containing the file name and `og:image`
-   pointing to `/assets/by-id/<media-id>` (or the default image if the file
-   has no thumbnail yet).
-
-5. Simulate a real crawler against the root, exercising the full
-   nginx → rewrite → backend path:
-
-   ```bash
-   curl -A "Slackbot-LinkExpanding 1.0" "http://localhost:3449/?file-id=<FILE_ID>"
-   ```
-
-   The same URL with a normal user-agent must return the SPA `index.html`.
-
-6. Verify the thumbnail is public:
-
-   ```bash
-   curl -I "http://localhost:3449/assets/by-id/<MEDIA_ID>"
-   ```
-
-   Expect `200` without any session cookie while the flag is on, and `401`
-   with the flag off (restart the backend after changing flags).
-
-7. To see the actual preview card rendered by Slack/Discord you need a
-   publicly reachable URL (`og:image` is built from `PENPOT_PUBLIC_URI`), so
-   use a tunnel such as ngrok; for local verification the `curl` checks above
-   are enough.
-
-## Automated tests
-
- * `backend/test/backend_tests/http_link_preview_test.clj` — endpoint behavior:
-   default context, file with/without thumbnail, non-existent and malformed
-   file ids, deleted file, only-deleted thumbnail, latest-thumbnail revision
-   ordering, file-name HTML escaping, response headers, file-beats-project
-   priority, decisive file-id (malformed vs absent with a project id),
-   project and team links, and flag disabled.
- * `backend/test/backend_tests/http_assets_test.clj`
-   (`objects-handler-file-thumbnail-bucket-link-preview-flag`) — the
-   `file-thumbnail` bucket is public only while the flag is enabled.
-  * `frontend/test/frontend_tests/router_test.cljs` — the `navigated` URL
-    surgery (mirror, skip, stale-strip, clear, unrelated-param
-    preservation, every-present-id, repeated-key, subpath base).
