Finlynq

Two ways to use Finlynq: a free managed cloud at finlynq.com/cloud, or self-host with Docker.

Open-source personal finance with a first-party MCP server (91 HTTP / 87 stdio tools) so Claude, ChatGPT, Cursor, etc. can query and manage your finances.

Track your money here, analyze it anywhere.

Quick start — hosted

finlynq.com/cloud — click, register, import a CSV. No infra to manage.

A public demo lives at the same URL (username demo / password finlynq-demo, resets nightly). Connect it to Claude by pasting https://finlynq.com/mcp into Claude → Customize → Connectors.

Quick start — self-hosted

curl -O https://raw.githubusercontent.com/finlynq/finlynq/main/pf-app/docker-compose.yml
docker compose up -d

Then open http://localhost:3000 and register. App + PostgreSQL run in Docker; sensitive fields are encrypted at rest with a per-user key derived from the account password. Remember to change the default PostgreSQL password and PF_JWT_SECRET before exposing the container to anything but localhost. Full setup notes at finlynq.com/self-hosted.
