In their own words
DBC
DBC is a free, open-source command-line tool for comparing database schemas across versions, environments, or database systems. Built with Go, it captures schema snapshots and checks tables, columns, indexes, foreign keys, and constraints for changes. It supports MySQL, PostgreSQL, SQL Server, Oracle, and SQLite. Optional data checksums can reveal data modifications, while exact row counts are enabled by default. Results can be output as text, JSON, or HTML. Database drivers run as separate executables and communicate with the core application over JSON-RPC through standard input and output; the README notes that drivers use timeouts but makes no certification or compliance claim. Building the core and drivers from source with Make is the documented installation route. DBC is licensed under MIT and is listed for Linux, macOS, and Windows. The releases page lists v0.1.0-alpha as a pre-release. CI/CD examples, Docker support, migration script generation, and a web UI appear on the roadmap, not among the available features.
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.
