A dependency-free GitHub Pages dashboard for current Tranquility incursions from EVE Online's public ESI API. It resolves readable system and constellation names, groups infected systems into Staging, Vanguard, Assault, and Headquarters roles, marks security status and NPC stations, and copies a system name when it is clicked.
Cards are headed by constellation, with the region underneath. The staging system remains in the Staging group. Region lookups are cached for the current page session; an unavailable region does not prevent the incursion from being displayed.
Use All, High-sec, Low-sec, or Null-sec to filter incursions by their staging system's security space. Your choice is saved in this browser. Incursions with unknown security remain visible under All. Click any system name to copy it; the station marker indicates an NPC station.
Countdowns use days, hours, and minutes for every phase. They are maximum estimates, not guaranteed expiration times. Each card identifies whether its estimate comes from the shared tracker or this browser's first observation.
The included GitHub Actions workflow publishes the site to GitHub Pages and polls ESI every five minutes. It writes data/incursion-state.json only when an incursion starts, ends, or changes state. This preserves the transition time used by Max. remaining without a server or paid database.
The workflow can also be run manually from the repository's Actions tab. GitHub may delay scheduled jobs during busy periods, and it automatically disables scheduled workflows in a public repository after 60 days without repository activity.
Use the included local server to serve the page and maintain state-change history while developing:
py server.pyor, if py is unavailable:
python server.pyThen open http://localhost:8080. Stop the server with Ctrl+C when finished. No API key, EVE login, package installation, or build step is required.

The UI handles timeouts, HTTP/network/CORS failures, empty results, malformed records, and failed name lookups. If name resolution fails, incursion data still renders with numeric IDs. If the shared timing file is unavailable, the page estimates timing from when that browser first observes the state.
The reference project calculates maximum remaining lifetime from its recorded lastStateChangeDate: three days for Mobilizing, eight days for Established, and one day for other states. ESI does not expose that timestamp, so the scheduled workflow runs scripts/update_incursion_state.py and stores each observed transition in data/incursion-state.json.
The file was initially seeded from the reference site for continuity, but the running page no longer contacts or depends on that site. If the tracker misses a transition, its next run records the time it first observes the new state.
ESI returns the staging-system ID and a flat list of infected-system IDs, but it does not identify Vanguard, Assault, or Headquarters systems. system-types.js contains the static system-role mapping from the public eve-incursions-node database seed dated 2026-08-03. The live ESI staging-system ID always takes precedence. Unknown systems are shown as Unclassified rather than guessed.
station-systems.js contains systems with at least one NPC station from the same public seed. Player-owned Upwell structures are not included.
system-security.js contains each solar system's security status from that seed. Values use the reference project's EVE-style formatting: positive security to one decimal place and zero or negative security to two decimal places.
The current incursion response supplies constellation_id, faction_id, has_boss, infested_solar_systems, influence, staging_solar_system_id, state, and type.
The deployed implementation is client-only and uses the browser's fetch API. No EVE login, API key, package installation, build system, or paid data service is required.
