Title: Hey everyone! After another year of building as a solo dev on nights and weekends, I&#x27;m back with an update on this post: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31083093">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31083093</a>.<p>TL;DR - ProjectionLab (<a href="https:&#x2F;&#x2F;projectionlab.com" rel="nofollow noreferrer">https:&#x2F;&#x2F;projectionlab.com</a>) is a privacy-friendly personal finance planning tool where you can create financial plans that go beyond the standard online retirement calculators. And by popular request, it now supports self-hosting for Lifetime users!<p>Something I&#x27;m grateful for is that our community here on HN is the difference between PL existing and not. There was actually a time early on when I was one day away from halting work on it. I posted here on a whim, and was shocked to receive some really constructive and energizing feedback that went on to power my indie dev journey over the past two and a half years.<p>As a quick recap, the story started when I dove head-first down the financial independence rabbit hole. I wanted a hands-on and visual way to explore the trade-offs between different life paths. One thing led to another, and I decided to build ProjectionLab.<p>After last year&#x27;s Show HN, I really put my nose to the grindstone, and here are some of the big developments:<p>- Self-hosting for Lifetime users (spin up your own private deployment, based on Docker Compose, includes support for auth&#x2F;encryption)<p>- Cash-flow visualization for each simulated year (sankey charts)<p>- Tax analytics (detailed breakdowns for projected income, taxes, marginal rates, effective brackets, etc)<p>- Major redesign of entire app, with landing page and resources now split into separate project<p>- Filing separately option to improve support for international locations that don&#x27;t have joint filing<p>- Roth Conversions and 72t (SEPP) distribution modeling<p>- Improvements to US tax estimation (Secure 2.0 updates, rental property tax deductions, Medicare + IRMAA, NIIT, principal residence exclusion, etc)<p>- Better support for planning as a couple<p>- More modeling options for cash-flow priorities to support different budgeting philosophies and goals<p>- Extra liquidity + withdrawal options, ability to fund expenses with specific accounts or route income to specific accounts<p>- Customization options for Monte Carlo simulations (characterization of success rates and outcome types, option to set random seed, etc)<p>- And a whole bunch more! (<a href="https:&#x2F;&#x2F;projectionlab.com&#x2F;changelog" rel="nofollow noreferrer">https:&#x2F;&#x2F;projectionlab.com&#x2F;changelog</a>)<p>The HN community has had a huge role in shaping my overall direction with PL, and I can&#x27;t wait to hear what you all think of the updates and where you would like to see things go from here.<p>As always, PL is free to try, with no need to create an account. It does not ask to link your financial accounts, and it has a sandbox mode if you just want to hop in and see how it works.<p>--Kyle
