Plans
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.
pgquarrel
pgquarrel compares PostgreSQL database schemas and produces SQL commands to bring a target schema in line with a source. It connects to PostgreSQL servers and reads catalog metadata directly, rather than depending on tools such as pg_dump. The project describes deploying schema changes to testing, staging, or production as its main use. Filters can narrow comparisons to selected object types or include and exclude schemas by pattern. Output goes to stdout by default, with options to save it to a file, print a summary, or place changes in one transaction. pgquarrel does not manipulate table data with INSERT, UPDATE, DELETE, or COPY. Its documented object coverage includes both complete and partial support; inheritance and roles are noted absences, and not all PostgreSQL objects are supported. Output may not work as expected when the source PostgreSQL version is newer than the target. The software is free under the BSD-3-Clause license, distributed as source through GitHub or a Git clone, and the listed latest release is 0.7.0.
