Again: early. But tabula is my consolidation of random "beancount/ledger" stuff regarding running my small business and startup. And bullboard my consolidation of random "beancount/ledger" stuff regarding everything investment related. The latter is just a CLI tool for now, and barely works. But once the businesslogic is done, I plan to add a web-interface alike ghostfolio to it. A tad simpler, I think, though.
Basically "bullboard" will be "yet another portfolio tracker/manager". Like so many out there (Ghostfolio, PortfolioDividendTracker etc), nothing new.
The only difference is that the source is your (existing) ledger/beancount file.
To be clear: it currently is a CLI application, but the goal is for it to be a web tool. Also selfhostable.
https://github.com/redstreet/fava_investor already exists in this space and is very similar: it's what I currently use. I don't like it, though. I dislike python for bookkeeping software and complex domain modelling. I dislike the UX of fava. And I prefer opinionated, focused software: call a spade a spade. Not "Assets", "Income" or "Transactions" but Stocks, ETFs, Bonds, Dividend, Sells, Buys etc.
