I kept guessing what to upgrade next
I play TH18 and lead a war clan. Every season I found myself manually checking which heroes still needed levels, whether my lab was behind, and how many builder-days I had left before maxing. Existing trackers were either dead, desktop-only, or required accounts I didn't want to create. So I built this.
Drop your player tag in the search bar above and you'll see your full upgrade breakdown in seconds — pulled straight from the Supercell API. No account needed, nothing stored. Works for any village from TH12 to TH18.
Every hero, troop, spell, pet, and defense listed with exact levels remaining, estimated time to max, and a rush risk flag.
Load your clan tag, assign targets with Mirror or Hit-Down, and generate war debriefs that show who pulled weight and who didn't.
Medal estimates, promotion odds, and opponent weakness analysis across all 7 league days. I added this because my clan kept arguing about rosters.
See all your equipment levels on one screen, compare against breakpoints, and figure out where your Starry Ore should go first.
How it works
You type in a player tag (the one that starts with #) and ClashOS sends a request to the official Supercell Clash of Clans API. Within a few seconds you get back a full breakdown of your account — heroes, troops, spells, defenses, walls, pets, and equipment — compared against the maximum levels available at your current Town Hall. This is live data, not pulled from a cached database, so it reflects whatever state your village is in right now. If you just finished an upgrade in-game, give it a minute and it'll show up here too.
Who this is for
If you lead a clan, you can check every member's war readiness before CWL signups instead of trusting their word. If you rushed your base and want an honest assessment of how far behind you are, the rush-risk analysis will tell you exactly which categories need catching up. And if you just want to know how many weeks or months you have left until your account is fully maxed, the time-to-max estimate gives you a real number instead of a guess.
Why there's no login
Clash of Clans already has player tags as public identifiers — anyone can look up any tag in-game. The Supercell API uses these same tags to return village data, so ClashOS doesn't need your email, a password, or any personal information. Your tag goes straight to the API call and back — nothing gets stored on my end, and you don't have to remember yet another set of credentials for something you might use once a week.
Common questions
Is my account data safe?
ClashOS only reads publicly available data through the official API — the same data anyone can see by searching your tag in-game. It cannot access your login, email, gems, or anything that Supercell doesn't expose publicly.
Does this work for lower Town Halls?
The tracker works for TH12 through TH18. Below TH12, the API returns limited data and some features (like equipment breakpoints) don't apply yet because those mechanics unlock later.
How often does the data update?
Every time you search a tag, ClashOS fetches fresh data from Supercell's servers. The API itself has a short cache, so if you don't see a change right after upgrading, wait a few minutes and try again — Supercell's servers need a moment to catch up.
