The best portfolio tracker for serious DIY investors: a 2026 buyer's guide
There is no single best portfolio tracker. There are honest criteria and a category that fits how you really invest. Here is how to judge any tool.
Search “best portfolio tracker” and you get a hundred articles ranking the same dozen apps, each swearing the winner is whichever one pays the biggest affiliate kickback. There is no single best tracker, the same way there is no single best shoe. There is a best tracker for how you actually invest, and you find it by deciding what “best” means before a listicle decides for you.
What “best” even means here
For someone who checks their balance twice a year, best is the prettiest number on the prettiest screen. For a serious investor it is a book you can still defend in three years. A few things decide that.
You want a reconcilable, auditable ledger: trace the big total back to the trades underneath, and see what changed and when. A tracker that shows a number it cannot explain is worse than a notebook, because at least the notebook never lies to you with a straight face. You want coverage, because your book is not one tidy account. It is taxable accounts, a pension or two, maybe a cold wallet and an exchange, holding shares, funds, crypto, options and cash, and the right tool swallows all of it into one home-currency view with the FX sorted. A tool that handles eighty per cent of your book is just a reason to keep a spreadsheet open for the rest.
Then the big one nobody prices: data ownership and privacy. Does this thing want your bank or brokerage password? If yes, your whole financial life moves onto someone else’s server, tied to logins that can move money, for as long as the connection lives. It is the largest trade you make when you pick a tracker, and we did the maths in why Strata is manual by design.
You want decision-support, not just balances, because a balance says where you are and nothing about why you own it. The better tools give you somewhere to write a thesis and keep a journal, so your reasoning gets written down before the outcome is known. Otherwise you reconstruct it afterwards to make past-you look clever. You want transparent analysis, so when a tool scores a holding you can see the inputs, the weights and the normalisation, because a black-box rating is faith, and faith belongs at a wedding, not in position sizing. And you want clean export, because pulling everything back out in a plain format is the honest test of who owns your data. It should be you.
The four kinds of tracker, minus the marketing
Nearly every tool is one of four animals. Judge each against the criteria.
Credential-linking aggregators log into your accounts and hoover up the balances. The pitch is “no typing”, and the bill arrives later. You hand over your logins, your data lives on their kit, and the connection breaks quietly: a broker tweaks a login page and a position doubles or freezes at last week’s price, with nothing flashing red. A book you cannot reconcile is a book you cannot trust.
Spreadsheets are the honest workhorse: total control, total ownership, infinitely bendy. The catch grows with the book. No live prices without brittle formulas, no audit trail, no thesis or journal worth the name. We weighed it up in portfolio spreadsheet vs app.
Single-broker dashboards are fast, accurate and free, for the one slice of your book that lives at that broker. They are single-account by definition, so the minute you own something elsewhere your “portfolio view” is one more tab to reconcile.
Privacy-first manual workbenches ask you to type in your own trades. That is a real cost and I will not pretend it is fun. What you buy is a ledger you can reconcile and audit, no passwords waiting in someone’s breach, every account and asset class in one place, and room for decision-support.
No animal wins everything. Which trade you are happy to make is the whole decision, and anyone who swears their pick has no trade-off is the one selling it.
So, how to actually pick
Forget the rankings and interrogate each candidate. Can you trace the headline total back to individual trades and see what changed? It needs to cover every account and asset class you hold in one home-currency view, and you have to know whether it demands your brokerage password. Then ask if there is room for a thesis and a journal, or only balances. When it scores a holding, can you see what produced the number? The last two are the easy ones to skip: whether it exports the lot in a plain format, and whether it still holds up when your book is twice the size. Answer those honestly and the field ranks itself. The criteria bite hardest for the scattered book, the exact mess we walk through in tracking a portfolio across multiple brokerage accounts.
Where Strata honestly fits
Strata is a privacy-first manual workbench, so those questions are its honest map. It never touches your brokerage credentials and never moves a penny. You type in your trades, the ledger is immutable so mistakes are voided rather than deleted, and your lots, cash and profit and loss are derived by replaying it. It pulls every account into one reconciled net-worth view, shares and funds and crypto and options and the cash sitting between them, then adds the decision-support most trackers skip: theses with invalidation signals that nag you when they break, a journal of plan versus what happened, and a factor engine where every cell opens up to show the signals and weights behind it.
The trade-off is the one I keep waving at: you do the data entry. If you want order routing, or a hands-off feed you never look at, Strata is the wrong shoe and I would rather you knew now. If you would rather own a book you can reconcile than rent a feed you cannot, you can build your portfolio and start typing it in.

The best portfolio tracker is just the one whose trade-offs you picked on purpose. Everyone else inherited theirs by accident.
