Who makes it
Chudlock is an independent fan project, built and run by one developer. It isn't affiliated with or endorsed by Valve: Deadlock, its heroes and its art are Valve's.
What's here
- Your matches: search your Steam name and every death in your recent games is explained, with how you compare to players on your hero at your rank.
- Hero tier list: every hero graded by win rate over the last week, overall or at your rank, with a page each for counters, best teammates, the most popular build and ability order.
- Hero matchups: every hero's win rate against every other hero over the last week, as one counter chart.
- Street Brawl tier list: every hero graded by win rate in Street Brawl, the 4v4 mode, on its own wider tiers, with the items each buys most.
- Hero builds: what players buy on each hero, and in what order.
- Item tier list: every shop item graded against the others at its price, with a page each.
- Item shop: every item where the game's shop puts it, with each one's grade and how its buyers did this week.
- Scout a lineup: your odds against any enemy team, the toughest match-ups and lanes, and the items that beat it.
- Compare players: two to six players side by side on rank, win rate, KDA, souls, damage and grades, on the same hero, and as teammates and opponents, with a link and a card to share.
- Patch notes: every patch Valve has posted on Steam, in full, with what each one did to hero win rates.
- Meta report: a report on every complete week, by rank: tiers with sample ranges, who rose and fell since last week and the last patch, bans and items.
- Ranks: how players spread across the ranks, how far up each one sits, and the heroes that win most at each.
- Leaderboards: 20 boards for every hero, from most games to the hall of shame, each with the top 1,000 players, plus Street Brawl boards for games, wins and win rate. Also Valve's own ladder for every region and hero, with moves since yesterday, and one-trick boards for players who put half their games into one hero, and rating boards for who plays best for their rank.
- Top players: the top of each region's in-game leaderboard, and pros' settings and gear taken from their own Twitch pages.
- Live matches: the top games being played right now, with each side's souls and objectives and the average rank. Players are shown by hero only, never by name.
- Cups and leagues: run a 1v1 or 6v6 cup or a league season for your community, free. Sign-ups, check-in, brackets, lobbies and results read from the games.
- Quests: three daily and three weekly quests, the same for everyone and checked from your public matches, with titles, frames and flair to earn. Never for sale.
- Discord and Twitch bots: your last game, builds, pro settings and counters in chat.
Everything on the site is free, and nearly all of it works without an account. Signing in with Steam puts your own matches and leaderboard places a click away, and lets you take a mastery prestige or claim a quest.
Where the data comes from
Matches come from the community-run deadlock-api, which collects public Deadlock match data, including Steam names and avatars. Hero and item details (names, art and what each item does) come from the game's own files, through the same project. The privacy page covers what that means for your data.
How the numbers work
- Hero tiers are win rate over the last 7 days: S from 52%, A from 50.5%, B from 49%, C from 47.5%, D below that. A hero needs enough matches at a rank to place there.
- Item grades compare an item's win rate with the average for items at the same price, because the dearest items are bought by players who are already ahead: S from +3, A from +1, B from −1, C from −3 points, D below that.
- Your matches are compared with players on the same hero at your rank, using the last 30 days of matches. Those comparisons are approximate.
- Match grades and the MVP use Mastery's scoring: each player's souls, kills, deaths, assists, last hits and denies a minute against the usual for their hero at the rank recorded for the match, as a grade from S to D. Unranked games record no ranks, so they're compared with all ranks, and a grade can differ from the one on the player's Mastery page. The MVP is the best score on the winning team, because the score doesn't see who won. Bot games, private lobbies, Street Brawl and players who left aren't graded.
- The Chudlock rating is the average of those game scores over a player's last 100 standard games, newest counting most, held close to 0 until there are enough games and shown with the range it most likely sits in. It says how well someone plays for the rank they play at, so it doesn't compare ranks. The formula, a worked example and its limits.
- Win chance is a pair of fitted models: one gives each side's chance before the game from the heroes picked, the other follows the game from its souls lead, buildings and Mid Boss. How they work, how often they were right on matches they had never seen, and when they were last fitted.
- Drafts and lanes work from the same kind of frozen model: the draft room ranks picks by the team chance they give, and a lane model predicts who is ahead in each lane at 9:00.How drafts and lanes work: the draft code format and how often the lane model was right on lanes it had never seen.
- Chud % is a joke stat: a checklist of habits players tease each other about, like feeding and soul hoarding, with every point itemised and the numbers behind it. It isn't a skill rating and doesn't predict wins.
All of it is association across thousands of matches, not a guarantee: a win rate says how a hero or item is doing, not why.
