StockMarketEye is a paid desktop app that has served offline-first investors well for over a decade. Foliolytic is a free browser-based replacement with deeper risk-adjusted return analytics, no install footprint, and the same client-side data privacy. Here is the honest comparison.
Try Foliolytic Free →Replace StockMarketEye with Foliolytic if you don't need to work fully offline, you want deeper risk-adjusted return metrics (Sharpe, Sortino, alpha, beta), and you'd rather not pay a license fee. Keep StockMarketEye if true offline operation is critical, you've already invested years in StockMarketEye's data file, or you specifically prefer a desktop-native UI. Foliolytic and StockMarketEye both keep data on your machine — they just differ in install footprint and analytics depth.
No install · No license fee · 70+ metrics · Browser-based · Client-sideStockMarketEye launched in the mid-2000s as a desktop application for Windows, macOS, and Linux. It serves a specific kind of investor: someone who wants their portfolio data fully under their control, locally on disk, with no cloud sync and no broker credential storage. The user base skews technical, privacy-conscious, and stable. The product has not changed dramatically in recent years — and that's part of the appeal for users who already have years of data in their StockMarketEye file.
Foliolytic offers a structurally similar privacy guarantee — your data stays on your device — but delivers it through a browser instead of an installer. The CSV is parsed by JavaScript running locally, the metrics are computed locally, and nothing is uploaded. The trade-off is that you can't launch Foliolytic with no internet at all (the page itself has to load once). In exchange, you get no install, no license fee, no platform-specific build, and significantly deeper risk-adjusted return analytics.

If you've been using StockMarketEye for years, the differences below are the ones that actually matter — not surface UI changes.
Honest comparison: StockMarketEye has earned its license fee with users for a reason, and there are workflows where Foliolytic does not replace it.
$0 / month, $0 / year, no paid tier. Free unlimited use, all metrics, all broker formats. Funded by a self-imposed budget.
StockMarketEye operates on a license-fee model. Per their website, pricing typically involves a one-time or annual fee structure that has shifted over the years. Verify the current price at stockmarketeye.com before purchasing — pricing on this kind of mature desktop app is often available only through their checkout flow.
StockMarketEye supports CSV export of holdings and transaction history. Foliolytic ingests broker-format CSVs directly, so you have two clean migration paths.
If you still have access to the brokerage account StockMarketEye is tracking, the cleanest path is to download a fresh transaction-history CSV directly from your broker (Schwab, Fidelity, Vanguard, Interactive Brokers, etc.) and drop it onto the Foliolytic homepage. Foliolytic's format detector identifies the broker automatically and reconciles tickers, dividends, and splits.
From StockMarketEye, use the export function to write your transaction history to CSV. The standard CSV layout is parseable by Foliolytic. Note: re-uploading the original broker CSV (Option A) is usually cleaner because StockMarketEye sometimes normalizes ticker symbols in ways that Foliolytic's resolver handles differently.
Within seconds of upload, Foliolytic shows your Sharpe, Sortino, drawdown profile, alpha vs S&P 500, beta, R², XIRR, and 60+ other metrics StockMarketEye does not natively compute. Use the comparisons to spot patterns StockMarketEye's flatter analytics didn't surface.
Foliolytic is the right tool for you if any of these describe your situation:
Foliolytic is the wrong tool for you if any of these are core to your workflow:
Drop a brokerage CSV onto Foliolytic. No install, no license fee, no signup, your data stays in your browser.
Analyze My Portfolio Free →StockMarketEye remains a paid desktop application for Windows, macOS, and Linux. Per their website, the license fee structure typically involves a one-time or annual fee — verify the current price at stockmarketeye.com before purchasing. The product has been in market for over a decade and has a loyal following among offline-first investors.
Foliolytic is a free, browser-based alternative that does not require installation on your machine. It ingests brokerage CSVs and computes 70+ risk-adjusted return metrics including Sharpe, Sortino, XIRR, max drawdown, alpha, beta, and R-squared. There is no license fee, no platform-specific build, and no signup.
A browser-based tool runs identically on Windows, macOS, Linux, ChromeOS, and any device with a modern browser. There is nothing to install, nothing to update, no platform-specific bugs. With a privacy-conscious browser-based tool like Foliolytic that processes data client-side, you also get the privacy benefit of a desktop app (data stays on your device) without the install footprint. The trade-off is that you cannot work fully offline — you need a browser open.
Foliolytic is a web app, so it requires an active browser session on a tab loaded from foliolytic.com. The CSV processing itself runs locally in the browser once the page is loaded — but you cannot launch Foliolytic without an internet connection at least once. StockMarketEye runs fully offline after install. If true offline operation is essential to your workflow, StockMarketEye is the better fit.
StockMarketEye supports CSV export of holdings and transactions. Foliolytic's format detector handles the standard CSV layout. The cleanest path, however, is to skip StockMarketEye as the middle layer and re-upload your original brokerage transaction CSV into Foliolytic — Foliolytic auto-detects 30+ broker formats.
Yes. Foliolytic computes Sharpe ratio, Sortino ratio, Treynor ratio, Calmar ratio, max drawdown, Ulcer Index, alpha, beta, R-squared, XIRR, and 60+ other risk-adjusted return metrics. StockMarketEye's analytics are more limited — primarily focused on cost basis tracking, total return, and dividend reporting. If you specifically want quantitative analytics, Foliolytic is the better choice.
Foliolytic processes your CSV entirely client-side in the browser. No transaction data is uploaded to any server. There is no account creation, no credential storage. The privacy model is structurally similar to a desktop app like StockMarketEye, but without the install.
