Sure

Open source · OSI-approvedStatus: unknownNew

Self-hosted personal finance app for everyone

Sure is a free, self-hosted personal finance app that tracks accounts, transactions, investments, and budgets with the operator holding all of the data. It serves individuals and households who want an all-in-one money manager without handing financial records to a vendor, continuing the open-sourced Maybe Finance codebase as a community-maintained fork.[1][2]

Quick verdict

Sure suits households that will self-host to keep every account, transaction, and budget under their own control, accepting Docker maintenance and community support. Skip it when you need a vendor-hosted product, hands-off onboarding, or documented SSO and offline guarantees.[1][2][3][4]

Key features

  • Account tracking across asset types: link bank accounts from over 10,000 institutions, follow stocks and crypto, and record property, vehicles, and other assets and debts in any currency, all charted in one place.[1]

  • Manual account entry with CSV import: add any account by hand through custom flows and import accounts from CSV files when automatic linking is unavailable or unwanted.[1]

  • Transaction management with rules and automation: edit transactions individually or in bulk, split them, and set rules that categorize and organize new activity automatically.[1][2]

  • Budget planning with limits: set spending limits per category, follow budget progress over time, and adjust allocations as income and expenses change.[1]

  • Bank and brokerage sync through built-in providers: connect accounts via Plaid, SimpleFIN, Enable Banking, Akahu, Coinbase, Binance, and other documented providers, with provider connections managed by admin users.[1]

  • Distinct asset and debt accounting: asset balances rise with income and fall with spending, while liability balances show amounts owed, matching standard accounting and card-provider statements.[1]

  • Multi-client access with API: use Sure from a browser, the macOS desktop app, the mobile app, API clients, and LLM agents against the same self-hosted instance.[1]

  • Docker-based self-hosting with standard operations: deploy from the example compose file, configure a secret key and database password, add optional SMTP email, and expose the instance publicly through an optional Cloudflare Tunnel.[1]

Who will love it

  • Households consolidating scattered accounts will value one self-hosted dashboard for banks, investments, crypto, property, and loans instead of several vendor logins.[1][2]

  • Budgeters who mix manual entry with automation will value CSV imports and transaction rules alongside bank sync for accounts that cannot link.[1][2]

  • Privacy-minded self-hosters will value keeping the full financial record on their own infrastructure under a copyleft license with API access for their own tooling.[1][2]

Who should avoid it

  • Non-technical users who want zero-maintenance finance software should avoid it: deployment, updates, backups, and SMTP setup assume server comfort.[1]

  • Shoppers wanting a vendor-hosted product with support should avoid it: no proper hosted version exists yet, and help runs through community Discord and GitHub issues.[1]

  • Teams needing SSO, documented offline use, or enterprise support should avoid it: none of these are documented for Sure.[1]

Alternatives and compatibility

Actual is the closest catalogue alternative: both are self-hosted open-source finance apps where a household adds accounts, manages transactions, and plans budgets, so adopting one means following the same account-tracking plus budgeting workflow in the other.[1][2][3]

Sure descends directly from Maybe Finance: it is a community fork of the archived Maybe Finance repository, not affiliated with or endorsed by Maybe Finance Inc.[1]

The practical difference is scope and method: Sure covers accounts, investments, and budgets broadly with many bank providers, while Actual centers on local-first envelope budgeting from cash on hand.[1][2]

Questions worth asking

How much does Sure cost per month?

The software itself costs nothing: Sure is free to self-host under AGPLv3. Running it on your own hardware carries no software fee; one-click hosts such as Railway or PikaPods bill separately through those providers at their current rates, unchecked in this pass. A demo environment collects voluntary contributions. Prices checked October 13, 2026.[1][2]

Can you self-host Sure?

Yes. The official guide deploys Sure with Docker Compose using a generated secret key and a Postgres password, with optional SMTP settings for email and an optional Cloudflare Tunnel for public access. The repository ships a Dockerfile and an example compose file. Self-hosting means owning updates and backups.[1][2]

Is Sure the same as Maybe Finance?

Sure is a community-maintained fork of the archived Maybe Finance project, which the original team open-sourced after spending nearly 1 million dollars building it. It is not affiliated with or endorsed by Maybe Finance Inc., and the Maybe name and logo are trademarks of that company.[1][2]

What is the best Sure alternative for non-technical users?

A hosted budgeting service is the safer pick when you need automatic bank connections with no server maintenance and finished mobile apps. Sure needs no code for daily budgeting, but deploying and maintaining the Docker setup assumes comfort with the command line and server upkeep.[1][2]
