* feat(exchange-rates): add Frankfurter as an exchange-rate provider Frankfurter (frankfurter.dev) is a free, keyless FX rates API backed by ECB daily reference rates, with no published rate limit and no auth flow to maintain (unlike Yahoo Finance's reverse-engineered cookie/ crumb auth or TwelveData's fast-exhausting free tier). Follows the Provider::MoexPublic template: Faraday client with retry middleware, SslConfigurable for self-hosted CA support, a light RateLimitable throttle, and a FRANKFURTER_URL env escape hatch for self-hosters. Registered as exchange-rates-only (no security/stock data) and added to the hosting settings dropdown. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(provider): switch Frankfurter to the v2 API v1 is explicitly marked "frozen" on Frankfurter's own root endpoint; v2 is "current" and covers 201 currencies across 84 central banks vs v1's ~30 ECB-only. Confirmed via the v2 OpenAPI spec and live requests: - Single-date lookups now use GET /rate/{base}/{quote}?date=..., which carries weekends/holidays forward server-side (a Saturday returns a real rate directly), so the provider no longer needs its own lookback-window logic. - Range lookups now use GET /rates?base=..."es=...&from=...&to=..., a flat array of { date, base, quote, rate } records (v2's shape) instead of v1's { "rates": { date => currencies } } hash. - Every calendar day in a range is present (v2 gapfills itself), rather than v1's omit-non-trading-days behavior. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(provider): sanitize currency codes before URL path interpolation from/to were only upcased before being interpolated directly into the URL path in fetch_exchange_rate (GET /rate/{from}/{to}). Low risk since currency codes come from validated internal sources, but adds cheap defense-in-depth: strip anything that isn't A-Z, matching the ISO 4217 format real currency codes always take.

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.
To stay compliant and avoid trademark issues:
- Be sure to include the original AGPLv3 license and clearly state in your README that your fork is based on Maybe Finance but is not affiliated with or endorsed by Maybe Finance Inc.
- "Maybe" is a trademark of Maybe Finance Inc. and therefore, use of it is NOT allowed in forked repositories (or the logo)
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.
