What ProxyDisc is

ProxyDisc is a free tool for Zenless Zone Zero players that answers one question quickly: is this drive disc worth keeping, and who should wear it?

Why it exists

Drive discs drop constantly, and most of them are not worth the materials it takes to level them. Judging a disc means checking its set, its main stat and four substats against what each of your agents actually wants. Doing that by hand, across dozens of agents and their alternative builds, is slow and easy to get wrong.

ProxyDisc does that comparison for you. Enter a disc and it grades it against every agent you play, using each agent's recommended sets, main stats and substat priorities. You get a clear keep, maybe or recycle call, and a grade for every agent who can use it.

What you can do with it

• Scrap or stash. Rate a disc the moment you pick it up, at any level.
• Loadouts. See what each agent is wearing, with a build score out of 100, and swap discs between them.
• My discs. Keep a library of the discs you own and see who each one suits best.
• Upgrades. Record each roll as you level a disc, and see the best and worst it can still finish at, so you know when to stop spending on it.
• Agent index. Browse every agent's build: their 4-piece set, 2-piece options, main stat per slot and substat order. Each agent also has their own build page.

The way grades are calculated is explained in full on How grading works.

Where the build data comes from

Each agent's recommended build is curated by hand from community build guides and kept up to date as new agents and balance changes arrive. Agents with more than one viable build, for example a team-specific variant, have each build listed separately. If you spot a build that looks wrong, the contact form in the tool sends a message straight to the maintainer.

Your data

There is no account to make and nothing to sign in to. Everything you save, your discs, loadouts and settings, is stored in your own browser. The tool includes a backup feature so you can move your data to another device. See the privacy policy for details.
