* fix(holdings): carry provider cost_basis forward to calculated rows Providers like IBKR Flex emit holdings on report_date and only include trades within the query window. The reverse calculator + gapfill therefore produces rows past report_date with nil cost_basis, even though the provider supplied a basis on the snapshot. That nil basis silently blanks `Trend`, the Reports "Total Return" card, the Top Holdings return column, and Gains by Tax Treatment, because every one of them gates on `holding.avg_cost`. When a calculated row would otherwise have no usable cost_basis, backfill it with the most recent provider-supplied cost_basis for the same (security, currency) on or before the holding date. Existing calculated/manual values are preserved (they outrank a provider carry-forward), and existing provider carry-forwards are refreshed when a newer snapshot supersedes them. * - Fix currency mismatch: provider snapshots were keyed by (security_id, currency) but calculated rows use account currency while IBKR provider rows use the security's native currency (e.g., USD vs EUR). Now keyed by security_id only; carry_forward_provider_cost_basis converts via Money#exchange_to at the snapshot date (same convention as ReverseCalculator for trade prices), with a ConversionError fallback. - Trim long inline comment to three lines - Fix safe-nav inconsistency: existing.cost_basis.positive? -> existing&.cost_basis&.positive? - Add test: refreshes stale carry-forward when a newer provider snapshot arrives - Add test: carry-forward is a no-op for forward-strategy accounts with no provider holdings * fix(holdings): prevent overwriting zero-valued manual cost basis Ensure that manual cost basis entries with a value of zero (e.g., for free shares) are not overwritten by provider carry-forward values during materialization. Additionally, updated the logic to allow zero-valued manual or calculated cost bases to be preserved, and added tests to verify currency conversion and error handling during cost basis carry-forward. * refactor(holdings): allow zero-valued cost basis in provider snapshots Remove the filter that restricted provider cost basis snapshots to values greater than zero. This ensures that manual cost basis entries with a value of zero (e.g., for free shares) are correctly captured and available for carry-forward logic. * perf(holdings): optimize provider cost basis snapshot lookup Filter provider cost basis snapshots by the security IDs present in the current holdings set to reduce the amount of data loaded into memory. * refactor(holdings): move PortfolioCache FX fix to dedicated branch Remove date-accurate exchange rate fix from this branch — it has been split into fix/portfolio-cache-historical-fx-rate to keep concerns separate. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * revert(portfolio_cache): restore date-accurate FX in get_price36676784removed date: date from exchange_to intending to move it to fix/portfolio-cache-historical-fx-rate, but that branch was a duplicate ofdb1051d2which was already in main. The revert therefore regressed portfolio_cache.rb below main's state. Restore the historical exchange rate lookup so this branch no longer removes a fix already present in main. * fix(portfolio_cache): restore date-accurate FX and its test36676784removed date: date from exchange_to and deleted the historical FX test, intending to carry them in fix/portfolio-cache-historical-fx-rate. That branch was a duplicate ofdb1051d2already in main, so the removal regressed portfolio_cache.rb below main's state. Restore both. --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

Sure: The personal finance app for everyone
Get involved: Discord • Website • Issues
Important
This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
Backstory
The Maybe Finance (archived/abandoned repo) team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Hosting Sure
Sure is a fully working personal finance app that can be self hosted with Docker.
Forking and Attribution
This repo is a community fork of the archived Maybe Finance repo. You’re free to fork it under the AGPLv3 license — but we’d love it if you stuck around and contributed here instead.

Performance Issues
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
