01 · The problem
You still own the spend. So you either check every change by hand, or you trust a number you can't explain to your boss, your client or yourself.

Prices checked on 4 Sep 2026 against each vendor's pricing page. Features from G2, Capterra and Q2 2026 analyst notes. Pacvue publishes no prices, so its figure is a third-party estimate.

FAQ
Common questions.
Three things. Price: Mirox publishes its prices and has a free 30-day trial with no card. Pacvue publishes no prices (third-party estimates: about $500/mo or 3% of ad spend), and Perpetua starts at $695/mo plus an unpublished percentage above $10K spend. Transparency: every Mirox bid change comes with the numbers behind it, exportable as CSV. Marketplaces: 12 Amazon marketplaces, each with its own limits, currency and keyword language.
Every bid passes seven safety checks first, including a kill switch, a daily spend cap and a ROAS limit. If one fails, the bid is stopped and logged with the reason. And during the free 30-day trial nothing goes live: you see what Mirox would do next to what your current setup did.
Yes. Mirox works in 12 marketplaces: Germany, France, Italy, Spain, Netherlands, Belgium, Poland, Sweden, UK, US, Canada and Mexico. Each has its own ROAS targets, spend caps and currency, and keywords are matched in the local language. Starter covers two marketplaces, Growth up to six.
Mirox connects through Amazon's official login (OAuth), so we never see your password, and it can't change a bid until you turn on Live Mode. Your data is stored in the EU by Mirox, LDA (Portugal). We don't sell or share it, or use it to train third-party models. A signed DPA is available, and required on Growth and Scale.
Yes. Connect Mirox to Claude, ChatGPT, Cursor or any app that supports MCP, and ask about your campaigns in plain words: how they are doing, why a bid changed, what a change would do. Every plan, including the free Simulation Mode, can read, explain and simulate. On paid plans the assistant can also propose changes, and nothing changes until you approve it. Setup takes about two minutes and is on the MCP connector page.
Export and go. Every change Mirox made exports as CSV with the original Amazon IDs and the reason for each. Disconnecting stops Mirox within seconds. Paid plans are month-to-month and cancel from the dashboard, and the trial needs no card.
