Spatial grid BFS
A pre-built spatial grid gives O(bucket) nearest-neighbour lookups, so the in-range set is found without scanning every system in New Eden.

Jump Range Calculator
Which systems your capital reaches in one jump
Pick the origin system, capital ship class and JDC level. The tool returns every system reachable in a single jump with light-year distance, security status and region. The computation leans on the spatial indices pre-built by the Capsuleers.app SDE layer.

How it works
1
Pick origin
Type the system you jump from
2
Set hull + JDC
Capital class plus Jump Drive Calibration level
3
Run scan
Compute every system inside one jump
4
Pick target
Read LY distance, fuel and kills
Features in detail
Fuel estimate
Each picked target shows one-way and round-trip isotope cost, scaled by the hull's burn rate and your Jump Fuel Conservation level.
Per-system intel
Reachable systems carry their security band, region grouping, exact LY distance, plus NPC-station and daily/today kill flags.
Excluded regions
Non-playable internal space (UUA-F4) is stripped from the candidate set so it never appears as a bogus jump destination.
Node index
A searchable list groups every in-range system by region with distance and kill tags, mirroring the selection you make on the map.
Shareable config
Origin, hull class, JDC/JFC levels and the picked destination are encoded into the URL, so a link rebuilds the exact same scan.

Key benefits
1
Instant results
Queries stay within a few milliseconds even at Black Ops range thanks to the pre-built spatial indices.
2
Every capital class
JF, Industrial, Dread, Carrier, FAX, Super, Titan, Black Ops. Range scales with the JDC level you set.
3
Two views
List of reachable systems with distance, security and region, plus a 3D overlay of the EVE Online cluster.
4
Chain with Jump Planner
For multi-jump routes, the Jump Planner mixes jump drive and stargates across the full system network.
Frequently asked questions
Does it work for high-sec?
No. Capitals can't jump in high-sec. The tool auto-filters non-jumpable systems.
Does it factor jump fatigue?
Not for a single jump. Accumulated fatigue is handled in the multi-hop jump planner.
Can I use it for Black Ops covert bridge?
Yes, with the Black Ops filter you apply the right range and find available systems.
