Real EXP/hr and mesos/hr for every map, for your class and level, solo or in a party. Every number is real farming, shared by players using the free Maple Classic Exp Overlay.
There's no secret formula and no guesswork. This site is filled in by players using the overlay who choose to share their farming. The more people share, the more maps, classes and levels it covers, and the more accurate it gets.
A free program for Windows that sits next to the game and reads your EXP bar, mesos and map.
It shows your EXP/hr, mesos/hr and time to your next level, and keeps a log of every map you farm.
If you say yes, every 15 minutes of non-stop farming is added here, anonymously, for everyone to use.

The overlay next to the game (and up close, with its log open).
Know exactly how fast you're leveling, without doing any math.
Anyone could send made-up numbers, so nothing is taken on trust.
Each run is 15 minutes of non-stop farming on one map with the same party. Breaks don't count.
Each player counts once (their typical run), however much they play.
Runs under half or over double what others get on that map are dropped.
A map is only ranked once 3 different players have farmed it. Before that, it's shown greyed out as early data.
Only 15-minute runs of non-stop farming, and only if you said yes in the overlay: the map, when you farmed it, your level, job and party size, the EXP and mesos you got, and a random ID for your copy of the overlay. Never your character's name. You can stop sharing any time in the overlay's settings. The newest runs also show in the bar at the very top (level, job, map, party and EXP/hr, rounded), with nothing about who shared them.
Under Lv 30 you're still 1st job, and everyone plays the same until they pick their 2nd job, so you see what every player of your class gets around your level. Path opens at Lv 30. From then on, each path only counts its own jobs: Shadower is Bandits, Chief Bandits and Shadowers, for example.
It only looks at your screen, like a screen recorder. It never touches the game's files or memory and never presses keys or clicks for you. It's open source, so anyone can check. It isn't made by or affiliated with Nexon, so like any third-party tool, you use it at your own risk.
No. The overlay and this site are free, made by a player for the community.
Each row is a map, and every row uses the same scale, so further right means more EXP/hr. Each dot is one player: their typical run on that map, however much they've played it. The gold line is the typical EXP/hr there (half of players get more, half less), and the shaded bar is what the middle half of players get. A short bar means most players get about the same; a long one means gear, skills and how busy the map is make a big difference. Hollow red rings are runs left out of the numbers for being under half or over double what others get, like an AFK player or a leech. Point at anything (or tap it) for the exact numbers.
A map is ranked once 3 different players around your level (close to your level: a map starts with players within 3 levels of yours and only goes up to 5, then 8, if it needs more players, and says so), on the same path, and solo or in a party like you, have shared a run there. Until then, it's listed under Early data, greyed out, so you can see what's come in so far. A new player's runs start counting a day after their first one, and once they have a few, so a flood of made-up players can't change the numbers at once. Map names that the game doesn't have (an event map, say) show once 3 players have shared them on 2 different days. The more people share, the faster it fills in. You can help by sharing yours!
