GE Flipper
Say how much GP you want to put to work, how many slots are free (1 to 8) and whether you want Quick, Balanced or Overnight. It plans those slots as one set, sized by your cash, the four-hour buy limit, how much each item really trades and how much risk the strategy allows.
Items are dropped for prices that are too old, trading on only one side, prices that swing too much, or margins too thin to survive slippage. For each pick you see the buy and sell price to offer, the most you should safely buy, profit after tax, ROI, hourly volume and a confidence score.
Prices are completed trades
The prices shown are trades that already happened, not offers sitting in the Grand Exchange. Confidence is about how good that data is; it isn't a promise the offer will fill or make money.
Prices come from the OSRS Wiki real-time price API, and the age of the trades behind each result is shown in its own columns.
Trade Journal
Anything you track arrives as Pending buy and moves through Bought, Listed for sale, Partially sold, Completed or Cancelled. Record as many buy and sale fills as you need, at whatever quantities and prices, and both sides average by quantity.
You see realized profit with tax taken off, win rate, capital traded and which positions need attention, and you can export everything as CSV. With the plugin, all eight Grand Exchange slots sit above the journal the way the game lays them out.
Performance
The toolkit suggests a strategy and some target prices; the journal records what you actually got. Performance puts the two side by side: results by strategy, by item, and plan against actual, weighted by quantity.
Every number comes from fills you recorded. A projection never counts as a result.
Alch Finder and Skilling Profit
Alch Finder assumes you'll pay the highest recent price buyers have paid and takes today's nature rune cost off the top, with Safer, Balanced and Show all settings. Skilling Profit prices 83 processing and gathering methods across 10 skills, with realistic actions per hour and notes on the things that ruin the maths.
These are baselines, not promises.
The plugin and PvM readiness
OSRS Toolkit Sync records partial and complete Grand Exchange fills, plus the moment you place or cancel an offer, so a position starts when you place the offer rather than when it fills. Player trades and PvM gear sync are off by default.
With gear sync on, opening your bank in-game lets PvM Readiness check your gear, bank and levels against hand-written checklists for 20 bosses. The plugin never logs into anything, clicks anything or changes your offers, and the sync service behind it is open source too.
