* Include newer providers in automatic family sync
Coinbase, CoinStats, Mercury, and SnapTrade all implement Syncable
and have Syncer classes but were not listed in child_syncables,
meaning their data only refreshed on manual sync button clicks.
* refactor(syncer): Open/Closed principle for provider sync
- Adding new providers requires modifying child_syncables (violates O/C)
- plaid_items missing .active scope (bug: syncs deleted items)
- snaptrade_items can exist without user registration → fails on sync
- Scattered knowledge about 'ready to sync' logic
1. **Registry pattern**: SYNCABLE_ITEM_ASSOCIATIONS constant lists all
provider associations that participate in family sync
2. **Encapsulated sync-readiness**: Each item model defines its own
`syncable` scope that knows when it's ready for auto-sync:
- Most providers: `syncable = active` (not scheduled for deletion)
- SnapTrade: `syncable = active + user_registered` (has API creds)
3. **Single loop**: child_syncables iterates the registry, calling
`.syncable` on each association
- Adding a provider = add to registry + define syncable scope
- Each model owns its 'ready to sync' business logic
- Fixes plaid_items bug (now uses .active via .syncable)
- Fixes snaptrade auto-sync failures (filters unregistered items)
- Easy to extend with new conditions per provider
- family/syncer.rb: Registry + dynamic collection
- *_item.rb (7 files): Add `scope :syncable, -> { active }`
- snaptrade_item.rb: Add syncable with user_registered filter
* Fix rubocop bracket spacing in SnaptradeItem syncable scope

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 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.

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.
