In their own words
driftcurve
driftcurve is an open-source household retirement planning engine for projecting finances and comparing retirement outcomes. It can model multiple household members, account types, debts, mortgages, pensions, Social Security and property sales. Its default Monte Carlo simulations resample annual market data from 1966–2024 across equities, Treasuries, residential real estate, inflation and Bitcoin. Users can adjust historical returns toward their own long-run targets or enter static annual assumptions. Risk-based spending guardrails solve for monthly spending and suggest adjustments based on portfolio thresholds and probability of success. A Compare page puts two scenarios on one chart. In default local mode, household data and saved scenarios stay in browser localStorage, while forecasts run through a Python backend; there is no account or server-side database persistence. Optional multi-user mode adds email/password accounts, server-side sessions, and stored profiles and scenarios. The project offers forecast and guardrails API endpoints, plus authentication, profile and scenario endpoints in multi-user mode. It is free under Apache License 2.0. The maker describes it as an educational modeling tool, not licensed financial, investment, tax or legal advice.
SQL Delta
SQL Delta is a Windows tool for comparing database schemas and data before changes reach production. SQL Delta 7 compares source and target databases that use the same server type; SQL DXP is intended for comparisons across different server types. Schema Compare shows structural differences in live databases or snapshots and lets users select what to include in a deployment script. Data Compare identifies row-level differences between environments. Users can review and edit synchronization scripts before executing them against a target, and projects can add custom script to deployment scripts. SQL Delta can save HTML reports and XML snapshots for release reviews or recovery work. Project completion events and command-line execution support automated runs. Editions are listed for SQL Server, MySQL, Oracle, and PostgreSQL. A separate Read Only Edition allows comparison and script generation but prevents direct script execution. The latest full product download has a 14-day trial. The MySQL single-license plan is $185 as a one-time purchase and includes a two-year software update subscription; purchase terms also describe a perpetual license.
