Resource ROI
See which planet pays back fastest.
Pick a resource and your exchange preference. Every planet that has it gets a costed plan: plan cost, daily profit and ROI in days, next to POPR, COGC, environment and infrastructure.
FIO Burn Needs FIO
Know when a base runs out.
Link your FIO account and Burn compares your real stock with what each plan uses: days left per material, thresholds you set, and a resupply list per base exported as XIT actions.
New to the game
Start from a typical setup, then make it yours.
An empty plan offers what other players typically plan on that planet. It is a guideline, not a rule: change every building and recipe until you have found your own best setup.
Shared plans
Send a plan as a link.
Anyone with the link can see the recipes and try changes, without an account. Good for asking your corporation for feedback.

Questions
Before you sign up.
What is PRUNplanner?
PRUNplanner is a free, open source planning tool for the browser game Prosperous Universe (PrUn). You plan bases and whole empires in it, find planets, compare what pays back and see when a base runs out of materials.
Is PRUNplanner free?
Yes. There are no ads and no paid tier. The code is on GitHub.
Do I need FIO to use it?
No. Plans, empires, Planet Search, Resource ROI and the calculators work without it. FIO Burn and Repair read your real in-game stock and buildings, so those two need a linked FIO account.
Can I try it without an account?
Yes. Open the example plan: you can change buildings and recipes and see the numbers update. You need an account to save plans of your own.
Is it an official Prosperous Universe tool?
No. It is a community project made by a player and is not made by the game's developer.
Which languages does it support?
English and 3 more, translated by players on Crowdin.
Plan your next base before you pay for it.
Over 6,000 players already do. Free, open source and translated by players. Registering takes a minute with the game open.
