Option Samurai is a market-wide options scanner: pick a strategy, set filters, and it searches every US optionable stock for setups that match, with ready-made scans and alerts. Optionscanner screens a smaller universe through rules you adopt, then keeps working after entry: it checks open positions against your exit rules, places orders through your own brokerage after a preview, and can run the process on paper. One is the widest net for finding a setup; the other is a process that selects, places and watches it.

Option Samurai describes itself as an option scanner, or screener. You pick a strategy, from covered calls and spreads to iron condors, calendars, diagonals, straddles and strangles (24 in all, by its count), set filters (170 of them), and it searches the whole US options market for setups that match. It adds ready-made scans, such as wheel candidates or unusual option volume, implied versus realized volatility analysis, a stock analyzer, a trade log for following positions, and alerts when new results match a saved scan. The question it answers is "where, across the whole market, is a setup that fits my filters?"
Optionscanner screens a defined universe (an S&P 500 morning scan plus the tickers you add) against a rule set you adopt and can edit, grades each setup on volatility richness, liquidity, event risk and direction, and builds the spread the rules select. It then keeps working after entry: positions are checked against exit rules you adopt, orders go through your own brokerage account after a preview, 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 what do my rules say about it now?"
Option Samurai's public materials, as read in October 2026, do not describe any of the following:
Both screen for options setups with volatility, liquidity and strategy filters, both compare implied with realized volatility, and both let you follow positions. The difference is the scope on each side of the trade: Option Samurai looks wider before entry, and Optionscanner stays with the position after it.
A trader whose process starts by searching the whole market for a strategy setup, then managing the trade at their broker, will find Option Samurai closer to that need. A trader who wants a written rule set to do the selecting, orders placed from the same screen, and software to watch open positions against exit rules will find Optionscanner closer. Finding ideas in a market-wide scanner and running the process in a rules engine is a workable pairing.
A wider scan finds more candidates, and also more that a disciplined rule set would reject; a narrower universe misses setups outside it. Scanner results and rule verdicts are both arithmetic on market data, not forecasts. Neither product is a source of investment advice, and both leave the decision to the trader.

Its public materials, as read in October 2026, describe a trade log for following positions and alerts on saved scans. They do not describe placing orders through a brokerage account or judging open positions against exit rules; those are the parts of the process Optionscanner adds.
Yes. A common pairing is a market-wide scanner for finding ideas and a rules engine for selecting, placing and monitoring the trades that pass a written rule set. Neither is a source of investment advice, and both leave the decision to the trader.
