A portfolio tracker you can try before you sign up.
Most trackers ask you to create an account before showing you anything. This one doesn't. The deck below is the real thing — change the share counts, switch between accounts, remove a holding, and watch every total recalculate.

Sample holdings and fixed sample prices, for demonstration. The real app fetches quotes on every load. Nothing here is a recommendation to buy or sell — total shown is $78,437.
Nobody shows you what you actually own
A brokerage only knows about the assets it holds. That is not a flaw — it is the boundary of what it can see. But it means that if your money sits in more than one place, no single login answers the question you actually have: what do I own, in total, right now?
So people build a spreadsheet. It works for about an afternoon. Then a price moves, a dividend reinvests, you buy something new, and the total is wrong again — quietly, without any warning that it has drifted.
The alternative on offer is usually an aggregator that wants your brokerage logins. For plenty of people that is a fair trade. For plenty of others it is precisely the thing they will not do.
One deck, entered once, priced on every load
StoxDeck is a stock portfolio tracker built around a deliberate trade: you type your holdings in, and in exchange nothing ever connects to your brokerage. What the app supplies is the part a spreadsheet cannot — current prices on every load, and gains computed from what you actually paid.
Enter a position once, with its share count and cost. From then on the deck values itself. Holdings from different brokers sit together in one total, and separate decks keep real money apart from a watchlist.
What it deliberately isn't
It is not an investment tracker that does everything. There is no allocation analysis, no dividend forecasting, no tax reporting, and no crypto or property. If you need those, an honest answer is that other tools do them and StoxDeck does not — we compare several of them in our roundup of free portfolio trackers. What is here is one job: knowing what you hold and what it is worth.
What you get
Every account in one total
Holdings from a taxable account, a Roth and an old employer plan sit in one deck. The number at the top is the whole portfolio, not one broker's slice of it.
Separate decks stay separate
What you own, what you are watching, and your retirement accounts are kept apart. A watchlist never inflates the total you actually hold.
Prices fetched on every load
Open the deck and it values itself against current quotes for US-listed stocks and ETFs. There is no price column for you to maintain.
Gains measured from real cost basis
Day, month, or since you bought — each figure is computed from what you actually paid, not from a starting price typed in once and forgotten.
No brokerage login, ever
You type in what you own. There is nothing to connect, so StoxDeck never sees a brokerage credential — it holds only the tickers and share counts you enter.
Your data leaves whenever you want
Export every holding to CSV at any point. Nothing about the format is designed to keep you here.
Who this is for
Four situations where a manual-entry tracker is the right shape of tool.
Holdings at three brokers
A taxable account at one firm, a Roth at another, and shares still sitting in a plan from a job you left. Each app shows a confident total and every one of them is partial.
Combining accounts into one view →A spreadsheet that keeps going stale
The sheet was accurate the day it was built. Then prices moved, you bought more, and the current-value column started quietly lying.
Tracker vs. spreadsheet, compared →Bought the same holding several times
Three purchases at three prices, and no single number for what you paid. The blend has to be recalculated by hand every time you add to the position.
Work out a blended cost basis →Unwilling to hand over account access
Aggregators want your brokerage logins. If that is the objection rather than the effort, manual entry is the trade you are looking for.
How data and privacy work →The concepts underneath
A tracker is only as honest as the numbers behind it. If you want to understand what it is computing: cost basis is what you paid and sets every gain figure; unrealized gain or loss is the gap between that and today's market value; and total return explains why price alone understates what a dividend-paying holding did for you.
Still weighing whether to switch at all? Take our free spreadsheet template instead — it is genuinely free, and the page is honest about where a spreadsheet stops working.
Questions
Can I try the portfolio tracker without signing up?
Yes. The deck at the top of this page is fully interactive — change share counts, switch between accounts, add and remove holdings, and every total recalculates. It uses fixed sample prices rather than live quotes, and no account is needed to use it.
Does StoxDeck connect to my brokerage account?
No. You enter holdings yourself, which is what lets one deck span every broker you use at once. Because there is nothing to connect, StoxDeck never receives or stores a brokerage credential.
How current are the prices in the real app?
The app fetches quotes every time you load a deck, so the value on screen reflects the current price rather than one saved earlier. The demo on this page is the exception — it uses fixed sample figures so the numbers stay stable while you experiment.
Which investments can I track?
US-listed stocks and ETFs. That covers most of what retail investors hold, but it does mean holdings on non-US exchanges, along with crypto and property, are not supported today. More markets are on the roadmap.
Is this a free portfolio tracker?
There is no published pricing at the moment, so we would rather not make a promise about what it will cost later. You can create an account and build a deck today without paying, and this page will be updated when pricing is decided.
Can I get my holdings back out?
Yes — export to CSV whenever you like. Your holdings are yours, and there is no lock-in built into the format.
You have already used it. The rest is your own holdings.
Type in what you own and StoxDeck prices it from then on — every account in one deck, without a single brokerage login.
