Actual budget does do that! You can tie it to automatically import transactions via SimpleFIN.

https://actualbudget.org/docs/advanced/bank-sync/simplefin/

Some things you'll need to manually do, like real estate valuations.

I really want this too. Neither Actual nor Firefly III support stocks/funds (open issues for Actual and for Firefly III.

I use GnuCash for my transactions, which I manually export from my accounts as QFX files. Although GnuCash has support for tracking fund values and generating reports, I do this with a custom Python script and Metabase instead.

If you want to track all your wealth with one single tool (bank accounts, stocks, bonds, funds, properties...) I would recommend plain text accounting tools suchs as ledger-cli, hledger or beancount. I began with ledger-cli and move later to hledger.

You will learn a lot of double entry accounting and you will keep accounts with plain text files with version control.

It is a rabbit hole...

Since no one has addressed the stocks part yet, give ghostfolio a try:

One thats under active development but getting more and more insteresting would be https://maybefinance.com/ – a Rails app. It supports investments and stuff which seems rare. For import they appear to double down on Plaid, which appears to also do a Europe thing which was recently added, however CSV is also supported

I use Actual and my solution is to just report the differences in investments value at the end of each week as a transaction. It’s not great but it affords me an opportunity to see trends in a different way and make adjustments feeling a little more informed. I even put my car in and just check KBB every year and update it. Helps with the year end net worth evaluation though it’s not the most flexible.

firefly iii maybe

I’ve used Gnucash for investment accounting and market valuation. It’s got plenty of features for tracking personal investments.

I spent a lot of time trying to find an open source self hosted tool to replace mint and ended up just moving to Monarch and paying. Honestly it's been a really great experience as if long as you don't mind the annual $50.

Firefly III constantly drops the previous version of PHP and always needs the current version and of requires PHP 8.4.

I haven't used it myself so I'm not entirely sure it's what you're looking for, but paisa might be worth looking into.

Firefly III and Actual are the usual answers here and both are great, worth trying first.

Throwing my own in for transparency since I built it: Finlynq (github.com/finlynq/finlynq, AGPL). Runs on docker + postgres. The differentiator vs firefly/actual is it ships an MCP server, so you can hook up an LLM (Claude, ChatGPT, whatever) and just ask it about your finances or have it log stuff for you. Also does proper multi-currency (stocks/crypto/metals) and encrypts account names at rest.

It's younger so a smaller community than firefly, being upfront. I'm actively building it and ship often, so if there's a self-host feature you'd want (specific reverse-proxy setup, backup format, etc) tell me and I'll prioritize. Demo if you want to click around before pulling the image: finlynq.com/cloud

I use a budget app for tracking income and spending on a transaction basis and then keep the rest of my finances in spreadsheets.

I used to use an app called moneydance several years ago. It was pretty much the only thing that ran on Linux but it was decent.

Some of the features you're looking for led me to switch to Quicken a few years ago. It's a legacy desktop app (Quicken Online sucks) and it's not very fast but it is still the gold standard for personal accounting software. I've honestly been happier with it than I was with anything else I've tried.

Thankfully Intuit sold it off so they can't enshitify it anymore.
