* fix: use ES256 instead of EdDSA for Coinbase CDP JWT signing Coinbase Developer Platform issues EC P-256 keys, not Ed25519. The previous EdDSA implementation would always return Unauthorized for any key generated via portal.cdp.coinbase.com. Switch to ES256 (ECDSA SHA-256) using OpenSSL, and convert the DER-encoded signature to the raw r||s format required by the JWT spec. API Secret field now accepts the full PEM private key directly (including BEGIN/END headers) as provided by Coinbase. * fix(coinbase): address PR review comments - Normalize escaped \n in PEM key before parsing (fixes pasting directly from the Coinbase CDP JSON download file where newlines are \n literals) - Extract parse_ec_private_key helper with docstring explaining both accepted PEM formats - Fix double-space style nit on encoded_header assignment - Remove ed25519 gem from Gemfile (no longer used after ES256 migration) - Add Provider::CoinbaseTest covering: JWT 3-part structure, ES256 alg header, kid claim, CDP payload claims, 64-byte raw r||s signature, escaped-newline key acceptance, and cryptographic signature verification * test(coinbase): fix base64url padding in JWT test assertions * chore: update Gemfile.lock to remove ed25519 gem * Sample credential in test * Comments field, not real key use * test(coinbase): generate EC key dynamically; drop scanner exclusions Generate a fresh P-256 key per test run with OpenSSL::PKey::EC.generate instead of hardcoding a PEM private key. This removes committed key material and the need to exclude the provider and test files from the pipelock secret scan, so those exclusions are removed too. Addresses review findings on hardcoded test key + scan exclusions.

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.
