OptionStrat is a strategy builder and visualizer: pick any structure, see the payoff diagram and the Greeks, and browse flow. Optionscanner also builds and draws a trade, but arrives at it through rules you adopt, then monitors the resulting position against your exit rules and can run the process on paper. One is a precise drawing tool for a trade you already have in mind; the other is a process that produces and then watches the trade.

OptionStrat is best understood as an options strategy builder and visualizer. You choose a structure, any number of legs, and it draws the payoff at expiry and over time, shows the Greeks, and lets you compare variations. It also carries an options-flow view. The question it answers is "what does this trade look like?"
Optionscanner arrives at a trade by rules: screen a universe, grade a setup, and build the spread the rules select, drawn on a price chart with its probability cone and breakeven. It then keeps working after entry: positions are checked against exit rules you adopt, and a paper-first agent can run the whole process under those rules. The question it answers is "which trade do my rules select, and how is it doing?"
Both draw a trade with its breakeven and probability figures and both report Greeks. The difference is where the trade comes from: in one you choose it, in the other the rules select it and you can override.
A trader who already knows what structure they want and wants the clearest picture of it will find OptionStrat's builder closer to that need. A trader who wants a written set of rules to do the selecting, and software to monitor the result, will find Optionscanner closer. Drawing a trade in one and running the process in the other is a common pairing.
A payoff diagram is a model; the market prices the legs. A rules engine selects from within its rules and will not surface a structure outside them. Neither product is a source of investment advice, and both leave the decision to the trader.
