Plugins & Marketplace¶
Much of GeoLibre's functionality ships as plugins. The Plugins menu activates built-in plugins, and the Manage Plugins dialog (under Settings) installs, updates, and removes external plugins from a curated registry.
The Plugins menu¶
The Plugins menu lists every available plugin under Activate plugin. Click a plugin to toggle it on or off; a check mark shows which are active.
Most entries toggle their plugin directly. The plugins that place a control on the map (GeoEditor, Annotations, Dimensions, Street View, and Mapillary) open a submenu instead, which activates the plugin and positions its on-map control in any corner: top left, top right, bottom left, or bottom right. Web Services and DGGS open a list of their sub-plugins, and plugins you install from the marketplace are listed under Installed, which also links to Manage Plugins….
Components live on the Controls menu
Measure, Bookmark, Legend, Colorbar, Minimap, View State, Search, and HTML are on-map component panels rather than Plugins-menu entries; toggle them from the Controls menu. The Print composer is under Project → Print Layout.
Built-in plugin reference¶
The table below is generated from the plugin registry, so it lists every
built-in plugin the app registers. Where is the menu that toggles it;
Web Services and DGGS are submenus of the Plugins menu, and a few
plugins live on the Controls or Add Data menu instead. Link name is the
value for a ?plugin= link; "menu only" marks the
plugins a link cannot open.
GeoLibre registers 70 built-in plugins.

God's Eye View¶
God's Eye View is inspired by the MIT-licensed bilawalsidhu/gods-eye-view, including its public-feed selection and normalization approach. Each enabled layer adds its provider credit to Cesium's Data attribution control. The datacenter, dam, and current-view infrastructure feeds use OpenStreetMap data under ODbL; Radio Browser is public domain; USGS earthquake data is U.S. public domain; CelesTrak requests citation; live transit combines MBTA, CapMetro, Metro Transit, HSL, OVapi, Entur, and TransLink feeds under their respective public-data terms; and the live TeleGeography cable feed is read from GeoLibre's Source Cooperative mirror under CC BY-NC-SA 3.0, including its NonCommercial restriction. Public camera imagery comes from TfL, Austin, Calgary, Fintraffic, Ontario 511, DriveBC, Live Traffic NSW, and Caltrans under each provider's public-data terms.
Some layers have options under their own row, saved with the project. Radio Stations has a Category filter (News, Talk, Weather / Emergency, Public Safety, Aviation / Marine, Traffic / Transit, Music, or Other), matched from each station's Radio Browser tags. Public CCTV Cameras has Snapshots on map: by default, snapshots appear only once you zoom in past street level; Always shows them at any zoom, and Off keeps plain markers, with the snapshot still in each camera's popup. Either way, cameras load only for a view less than 5° across.
Two layers use a key of your own, entered under API keys at the bottom of
the panel. Live AIS Vessels streams ship positions from
AISStream for the current view (up to 30° across) and
shows nothing without a key. Simulated Street Traffic works keyless; with a
TomTom key it also draws live congestion and
paces its vehicles by it. Keys typed there stay in the browser and are never
written to the project; VITE_TOMTOM_API_KEY or AISSTREAM_API_KEY under
Settings → Environment variables works too.
Open a plugin from a link¶
Add plugin=<link name> to a GeoLibre web address to open the app with that
plugin already active, as if you had picked it from the Plugins menu:
https://web.geolibre.app/?plugin=nasa-earthdata
List several with commas (?plugin=graticule,h3-grid). The full plugin id, such
as maplibre-gl-nasa-earthdata, works too. See
Deep-linking a plugin for how it combines
with a shared project and the read-only viewer.
The Link name column of the plugin reference gives the name for each built-in plugin.
Directions and Reverse Geocode are "menu only": they send what you click to a
public server, so they only open from the menu, after their one-time notice.
A plugin from the plugin registry opens from a link by its
full registry id, for example ?plugin=openrndt-geolibre. If it is already
installed it activates like a built-in one. If not, GeoLibre may prompt to
trust a compatible registry entry (showing its name, version, author,
description, and homepage), then installs and activates it only when
the current deployment plugin policy permits loading. Trust confirmation does
not bypass policy; a denied plugin will not load or activate. In read-only
layout=viewer, an installed registry plugin still opens, but the prompt is
skipped and uninstalled ones are never installed. This is distinct from project manifest URL trust, which is
suppressed by sideload: false. Permitted registry entries remain eligible
with sideload disabled. See Plugin policy.
Manage Plugins¶
Open Settings → Manage Plugins to browse the marketplace. The dialog is modeled on QGIS, with sections for All, Installed, Not installed, Upgradeable, and Settings.
- Search the registry and Install an entry with one click. Installation records the plugin's manifest URL and registers it immediately, with no restart.
- Update appears when a newer version is published; it re-fetches and re-registers the plugin in place, keeping the old version if the update fails.
- Uninstall (after a confirmation) unregisters the plugin at runtime and tears down any active control.
- The Settings section installs a packaged plugin (
.zip) with Install from file and manages additional plugin sources: extra local directories (desktop only) and manual manifest URLs.
Compatibility is checked against each entry's minGeoLibreVersion, so incompatible plugins are flagged rather than installed.
Trust model
The registry is a curated source, manifests require HTTPS (or HTTP on localhost, 127.0.0.1, or [::1] for development), and installs require explicit consent. Deployment plugin policy also governs whether external plugins load; trust confirmation does not bypass it. This client policy is bypassable and provides neither signing nor sandboxing.
Where plugins come from¶
- Curated registry: the marketplace fetches a versioned JSON registry, hosted by default at
plugins.geolibre.app. The registry and plugin bundles live in the opengeos/geolibre-plugins repository. - Manifest URL: point the Settings section at any
plugin.jsonmanifest URL. - Local directory: load a plugin from a local folder (desktop app).
- Plugin archive: install a packaged
.zipfrom Install from file; in the browser it is stored locally and reloads on your next visit. - Bundled drop-ins: plugins placed in
public/plugins/<id>/load automatically in a build.
Writing your own plugin¶
To build a plugin, see Reference → Plugin API for the TypeScript interfaces, the plugin.json manifest contract, and the list of built-in plugins.
USGS NLDI¶
See USGS NLDI workflows for point-to-flowline tracing, hydrolocation, upstream basin, COMID navigation, and GeoJSON export. It is activated from the Web Services submenu.
