Moneh: Personal Finance Tracker & API Gateway

Moneh: Personal Finance Tracker & API Gateway

A self-hosted personal finance system for a two-person household: a mobile-first SvelteKit app for logging expenses in under 10 seconds, backed by a Fastify API gateway that dual-writes every transaction to Supabase and the Actual Budget ledger with idempotency and automatic reconciliation. It also suggests next month's budget from recent spending and assigns it automatically at the start of each month.
