I built this to scratch an itch - tracking how some hypothetical portfolios might've played out across market regimes, with realistic simulation and daily pnl tracking.

Most tools available tend to ignore tax lot, cash drag, flexible strategy input or regime analysis. So I decided to ship my own in Rust (backend, NextJS UI) and worked on it over the last few months.

Having worked in the back office of a hedge fund, I have an understanding of how pnl and performance measures are computed. Honestly, it would've been shorter if I have prioritised better. For now, it supports tactical portfolio (fixed allocation) and planning to support more (flexible strategy and more complicated rules).

Key features: - Regime Awareness - Head-to-Head Portfolio Comparison - FIFO tax lot accounting - ETF and Crypto support - Automated daily valuation

Beta, free for now. Feel free to provide feedback: 1. Do you find this useful? 2. Whats missing in this that would make you use this more? 3. Would you pay for a tool like this?
