Your AI financial assistant. Open source. Self-hosted. Yours.

Alderfi is the open-source, AI-native personal finance platform. A conversational CFO built on MCP — private by design, portable by default, auditable always.

No spam. One email when the first alpha ships. Unsubscribe with a link.

AI-Native, not AI-bolted-on

Ask your finances anything. Get proactive insights — not a CRUD app with a chatbot glued on. Conversation is the product, not a side panel.

Self-Hosted & Private

Your transactions stay on your hardware. No vendor lock-in. No acquihire risk. No forced migrations when a bigger company buys your budget.

Built on MCP

The app is an MCP server. Use it from Claude, Cursor, your own agents, or our web UI — they're all equal clients. Your finances, any interface.

Why we're building this, right now.

On April 13, 2026, OpenAI acquired Hiro Finance. The product shuts down on April 20. User data is deleted May 13. Thousands of people who trusted an "AI CFO" with their budgets, categorizations, and financial history have four weeks to export and move on.

Existing open-source finance tools — Firefly III, Actual Budget — are excellent but weren't designed AI-first. We're building the option that should have existed before Hiro was acquired: a conversational, self-hosted, MCP-native finance platform whose roadmap can't be cancelled by an acquisition.

Be first when the alpha ships.

We'll email you once — when the first self-hostable alpha is ready. That's it. No newsletter, no drip, no growth-hacking.

The conversational interface IS the product. Not a feature, not a dashboard add-on. Ask your AI about last month's subscriptions, flag unusual charges, set a budget goal — all in plain language, all on your machine.

Common questions

When can I actually use it?
First self-hostable alpha targets mid-May 2026. Development starts in earnest after our internal May 1 go/no-go. We'll email waitlist subscribers the day the alpha ships.
Is this a Hiro migration tool?
No — but it will import your transaction history. If you have a Hiro export before May 13, keep it. We'll publish an importer in the first alpha. We're not cloning Hiro's features; we're building the open-source version of the category.
How is this different from Firefly III or Actual Budget?
Firefly III and Actual Budget are mature, well-loved finance apps — and an MCP server bolted onto Firefly III already exists. Alderfi is different because MCP and AI aren't an add-on. The core app is an MCP server. Every feature is conversational first, a form second. Think: "I spent $45 at dinner" versus clicking through a modal.
Where does my data live?
On your hardware. Alderfi is SQLite local-first by default. Categorization runs through a rule engine for the majority of transactions and a local LLM (Llama 3 8B via llama.cpp) for the ambiguous ones. Cloud LLMs are opt-in, never required. You can audit every query.
How will you make money, and will it ever go closed-source?
Open-core. The self-hosted core — conversational UI, rule + local-LLM categorization, SimpleFIN and CSV import — stays free and open under Apache-2.0 forever. A hosted version with premium connectors (Plaid), cloud LLM, and multi-device sync funds the project. The open source core will not be relicensed or restricted. You can fork it at any time.
