Zero-based web budgeting with an approval queue for imports and debt payoff planning.
The original Inzolo (an envelope budgeting site from around 2010) is still online at legacy.inzolo.com, where a banner says it is now EnvelopeBudget. This listing covers the current inzolo.com app, a newer zero-based product.
Research-based review, not hands-on testing. Last researched .
Inzolo is a web-based zero-based budgeting app with envelope rollover, a review queue for Plaid, SimpleFIN and file imports, and a debt payoff planner. Its Priority Ladder is still in development. Pricing is inconsistent across current vendor pages: the pricing page lists $30/year or $5/month with a card-required 30-day trial, while the changelog says free during early access.
Best for: People who want a calm, zero-based web budget with a review queue for imports and a debt payoff planner, and who are comfortable trying an early-stage app

Inzolo is a web-based zero-based budgeting app: assign every dollar to envelopes, import transactions through a bank link or file, then approve them in one review queue. It also lists a snowball/avalanche debt planner, reminders and reports. The Priority Ladder remains in development.
Research-based, not hands-on. Reviewed from public vendor pages and independent search results; I did not create an account, start a trial or connect a bank.
The current pricing page lists $30/year or $5/month, with a 30-day trial requiring a card. However, the Oct. 6, 2026 changelog says Inzolo is free during early access. The pages conflict; confirm the checkout terms before relying on the displayed price.
Zero-based envelopes roll over, and imported entries from Plaid, SimpleFIN, CSV or OFX/QFX wait in a review queue for approval. The vendor describes rules-first categorization with AI as a fallback. The debt planner compares snowball and avalanche payoff paths. The Priority Ladder is explicitly marked in development, not a shipped feature.
The privacy policy says data is not sold or used for advertising, supports passkeys, and allows export and deletion requests. It describes HTTPS and separate storage for provider credentials, but I found no at-rest encryption statement or independent audit. The current product is web-only; native iOS remains on the roadmap.
Hands-on reliability, independent security audit, and whether the free early-access terms still apply alongside the paid pricing page.
The current inzolo.com product is distinct from the older Inzolo site at legacy.inzolo.com. Ratings are set separately against a shared rubric.
