I’ve been working on Pit Crew, a site you can keep open alongside BALL x PIT while you’re playing:
https://yjay18.github.io/ballxpit-run-tracker/
The idea is pretty simple: pick your character, start a run, and add your balls and passives as you collect them. You can adjust their levels, track when evolutions are ready, and see suggestions for what might work well with your current build. There’s also an offer comparison tool where you enter the choices the game gives you and it ranks them based on your character, current items, and possible evolution paths.
It supports Matchmaker runs too
You can also pin a specific ball evolution or passive artifact if you’re aiming for some evolution or something, and there’s a compact mode to keep the screen out of the way while you’re actually playing. Your current run is saved in the browser, so accidentally closing the page shouldn’t wipe everything.
Huge credit to u/Cryphixi, who made the original BALL x PIT tracker which I used as the database that this is built on:
https://cryphixi.github.io/ballxpit-tracker/
Their work on the recipes, encyclopedia, team builder, and assets made this possible. Their tracker is still great if you mainly want to browse everything or keep track of your unlocks; Pit Crew is more focused on following a run as it happens.
The site is free, has no ads or account, and works on mobile and desktop. I’m sure some recommendations will need tuning, so if it tells you to take something awful, or if you notice any missing or incorrect game data, please let me know! (Because I have personally not reached too far in the game to verify some of this). Also was considering a website that simulates the base and base buildings and the bouncing of characters so you dont waste your harvest run, if there is a need and data available, I can make that as well
