Finlynq vs Era: open-source vs closed AI personal finance

When to choose Era

Era is probably the better pick if any of these matter to you more than owning your data:

You want bank sync to "just work" out of the box. Era ships with aggregator-grade automatic transactions across thousands of US institutions. Finlynq is file and email import only right now.
You want the most polished native mobile experience. Era's Agency is a mature native app. Finlynq now ships native iOS and Android apps too (on the App Store and Google Play), but they're newer and still maturing.
You want regulated investment advisory or brokerage. Era's Thesis (private beta) is an SEC-registered investment adviser with brokerage through Alpaca. Finlynq isn't, and it never will be.
You'd rather not think about Postgres, Docker, encryption keys, or password recovery. Era is hosted, and honestly that's the whole pitch.
You want shared household finances baked in. Era's multi-user shared views are first-class.

When to choose Finlynq

Finlynq is the one to pick if any of these matter to you:

You want the source code. Finlynq is AGPL v3 and it's all on GitHub. Era is closed-source, so you can't audit the MCP tool implementations, the encryption story, or what actually gets sent to your AI assistant.
You want to self-host. Finlynq runs on your own hardware with Docker and PostgreSQL. Era can't be self-hosted at any price.
You want per-user encryption with keys derived from your password. Finlynq's envelope encryption (AES-256-GCM with a scrypt-derived KEK) means even the operator can't read your transaction notes, payees, tags, or display names. Era's "AES-256 at rest"is a blanket claim about Era's infra, and the operator still holds the keys.
You want the bigger MCP surface. Finlynq exposes 109 HTTP tools and 93 stdio tools across budgets, transactions, portfolios, goals, loans, subscriptions, and rules. Era's public Context surface is 27 tools spanning accounts, connections, insights, billing, and a handful of other domains.
You want plaintext-accounting workflows. Finlynq is built for users who already think in ledger files; Era is not.
You want to own your data on the day Era pivots, gets acquired, or shuts down. With Finlynq, you do.

Side-by-side

	Finlynq	Era
License	AGPL v3	Closed source
Hosting	Self-host (Docker + PostgreSQL) or managed cloud	Hosted SaaS only

Multi-currency	Native, with per-currency cost-basis bucketing	US-bank-feed centric (no public multi-currency claim)
Investment / portfolio	Cost basis, dividends, FX-aware aggregation across accounts; not advisory	Thesis (private beta): SEC-RIA portfolio analysis + brokerage via Alpaca
Native mobile app	Yes, native iOS and Android apps (App Store, Google Play); newer and still maturing	Yes, Agency
Multi-user / household	No (single-user)	Yes, shared views
Pricing	Donation-based; same features on self-host and managed cloud	Freemium with paid tiers (specific amounts not disclosed publicly)

Migrating from Era

Export the raw transactions you can. Use Era's UI export if available, or screenshot category and recurring rules. (Verify Era's current export options on era.app before relying on them.)
Import into Finlynq. Use the staging-review pipeline at /import/reconcile: upload a CSV, review and edit each row, then approve. Multi-currency, transfer-pair detection, and dedup are all built into the staging flow.
Hook up your AI client. Open Claude → Customize → Connectors → "+" → paste https://finlynq.com/mcp. OAuth handles the rest. For self-host, point Claude at your own deployment's /mcp URL.

FAQ

Why are you comparing yourself to a paid product when you're free?▾

Because the comparison isn't really about price. It's about where your data lives, who can read it, and what happens if the operator pivots. Finlynq's argument is structural, not a discount.

Doesn't Era's bank sync just make this a non-comparison for most users?▾

For people who want one-click bank sync and don't care about source code or self-hosting, yeah, Era is the better default. Finlynq's audience is the people who specifically don't want a third-party aggregator holding their bank credentials, even one that's SOC 2 Type II.

Why does this read like a hit piece?▾

It isn't. Era ships real things: first-party MCP, OAuth-scoped tools, native mobile, and an investment-advisory product Finlynq legally can't offer. The honest difference is that Era is hosted convenience for people who trust an operator with their financial life, and Finlynq is the substrate for people who'd rather not.

Does Finlynq have a mobile app?▾

Yes. Finlynq has native iOS and Android apps on the App Store and Google Play. They are newer than Era's Agency, so Era's mobile experience is more mature today.

Will Finlynq ever offer regulated investment advisory like Era's Thesis?▾

No. Becoming an SEC-registered investment adviser just doesn't fit the AGPL self-hostable design. The regulator wants a single accountable entity, and the design wants none. Finlynq is the database, and you can hire whatever advisor you want to work against the data.
