Pricing
Spew is $4.99 per month with a 30-day free trial and no credit card required. There’s also a one-time $149 lifetime option if you’d rather pay once.
Monarch is $14.99 per month or $99 per year (about $8.25 per month when paid annually), with a 7-day free trial. Pricing is flat across the product: everyone gets bank sync, the full budgeting suite, and goals.
For most people Spew is meaningfully cheaper, especially if you take the lifetime option.
Bank sync depth
Both apps pull from your bank read-only. Monarch supports Plaid, Finicity, and MX, which helps with some smaller credit unions that only work on one of those providers. Spew uses Plaid, which covers the large majority of US banks.
Where they differ is what happens after sync:
- Spew auto-matches charges to the right bill row in your monthly grid. The cell turns green; your ledger updates. Anything Spew can’t match goes to a pending inbox you triage in seconds. Smart tagging learns from past categorizations and auto-tags new transactions going forward.
- Monarch presents transactions as a flat feed and lets you build category rules. Categorization is solid but more manual upfront.
If you think in “did I pay X this month,” Spew is more direct. If you think in “how did I spend across categories,” Monarch is more direct.
Forecasting
Spew has a drag-a-slider cash-flow forecast for the next 24 months. You can model “what if I get a raise in July” or “what if I add a $500 car payment in September” and watch your projected balance update live.
Monarch has a cash flow chart and goal tracking (e.g. “save $10k for a down payment by December”). Goals project forward based on your current savings rate. There’s no scenario modeling in the Spew sense.
If planning ahead is important to you, Spew pulls ahead here.
Budgeting style
Monarch is category-first. You pick budgets per category, watch actuals roll up, and adjust monthly. Groups, subcategories, and rollover behavior are all configurable.
Spew is bills-first. Every known bill, every month, in a grid. Variable spending (groceries, dining) lives in category groups that sit alongside bills. For people already using a Google Sheets budget, the model is instantly familiar.
Neither style is objectively better. They’re for different brains.
Households and couples
Monarch was built for couples from the start. Two logins, shared accounts, shared categorization, comments on transactions, the whole package.
Spew is single-user today. Shared accounts are on the roadmap. If you need true multi-user budgeting today, Monarch wins on this axis.
Privacy and data handling
Both apps connect to your bank read-only through data-access providers (Plaid for Spew, Plaid + Finicity + MX for Monarch). Neither stores your bank credentials.
Monarch is venture-backed and has published privacy documentation; check their current policy if data handling is important to you.
Spew is independent, doesn’t sell data, and the live demo runs entirely in your browser with nothing saved to a backend.
Best for
| You should pick… | If… |
|---|---|
| Spew | You think in bills, months, and want a real cash-flow forecast. |
| Monarch | You think in categories, goals, and net worth, and you share finances with a partner. |
| Spew | You have variable income or irregular bills. |
| Monarch | You want deep investment tracking alongside your budget. |
| Either | You just want a pleasant bank-synced app that isn’t Mint. |
Verdict
Pick Spew if bills and forecasting are your frame. The monthly grid, the slider forecast, Plaid autosync with smart tagging, and the flat $4.99/month (or $149 lifetime) make it a strong fit for people who want to plan.
Pick Monarch if you and a partner want a polished household budget with deep categories, goals, and net-worth tracking. It’s more money and less forecasting, but it’s excellent at what it’s built for.
