Bank-Sync Reliability Layer For Self-Hosted Personal Finance
Securo, an open-source self-hosted money manager, reached 1,072 GitHub stars but its issue tracker is dominated by reconciliation correctness bugs: credit-card transactions assigned to the wrong billing cycle, dashboard totals that disagree with the transaction view, and Pluggy bank sync failing on self-hosted OAuth. Privacy-conscious users want to leave Mint-style cloud apps, yet the open-source replacements break on the exact ledger math that makes a finance tool trustworthy. The wedge is a hardened bank-sync and reconciliation engine these projects can adopt instead of each re-deriving it.
Problem Statement
When a credit-card charge lands near the statement closing date, Securo files it in the wrong billing cycle, and monthly income and expense totals on the dashboard disagree with the transaction overlay. Pluggy bank sync fails on self-hosted deployments because the connect token is created without an OAuth redirect URI. A personal finance tool that reports the wrong balance is worse than a spreadsheet, so each project burns months re-implementing aggregator quirks and ledger math instead of features.
The Idea
A reliable bank-sync and double-entry reconciliation engine for self-hosted personal finance apps that need correct balances without rebuilding aggregation from scratch.
Why Now
Self-hosting moved from hobbyist to mainstream in 2026, and finance is the category where users most want their data off vendor clouds. Securo collecting a thousand stars in weeks shows the demand, while its open bug list shows the unglamorous correctness work that determines whether anyone keeps using a money tool past the first month.
