The short version

  • Only Maestro has a free tier, so it costs nothing to try first.
  • Each has a real cost: Adjust the vendor is owned by AppLovin, an advertising network and game publisher, so the party measuring campaign performance has a corporate interest in some of the inventory being measured.; Maestro cloud pricing is per concurrent device at 250 USD per month, so the cost is driven by how quickly you need the suite to finish rather than by how much you test, and a team wanting a fast pull request gate buys several devices at once.
  • They diverge on capability: Adjust covers Install and event attribution, Maestro covers YAML test flows.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Adjust

  • The vendor is owned by AppLovin, an advertising network and game publisher, so the party measuring campaign performance has a corporate interest in some of the inventory being measured.
  • Pricing is per attributed install on an annual commitment, meaning a successful campaign raises the measurement bill proportionally and overage above the commitment is charged at a worse rate.
  • App Tracking Transparency removed deterministic iOS attribution for users who decline tracking, so a significant portion of iOS reporting is modelled and the interface does not always separate modelled from observed.
  • Fraud prevention, audiences and the analytics layer are priced as separate modules, so a comparison against a competitor quote is only valid if module scope is matched line by line.
  • Attribution history stays with the vendor, so switching partners breaks year on year comparisons and the cost of leaving rises with every year of data accumulated.

Maestro

  • Cloud pricing is per concurrent device at 250 USD per month, so the cost is driven by how quickly you need the suite to finish rather than by how much you test, and a team wanting a fast pull request gate buys several devices at once.
  • YAML is deliberately limited, so tests with real conditional logic or data-driven permutations end up in embedded scripting blocks where the readability advantage that justified the format disappears.
  • Maestro drives the app as a black box, so it cannot assert on internal state, mock a network layer from inside the process or inspect application memory the way an in-process framework can.
  • The hosted device catalogue is narrower than dedicated device clouds, so testing against a long tail of specific manufacturer builds and older operating system versions still requires another provider.
  • The project rebranded from mobile.dev to Maestro, so a share of existing tutorials, blog posts and links point at old domains and documentation that no longer match the current tooling.

Answered from the vendors’ own pages

Adjust: Does AppLovin ownership compromise measurement?

There is no public evidence of manipulation, but the structural conflict exists. Some advertisers exclude Adjust for that reason alone and it is a legitimate position.

Maestro: Is Maestro free?

The CLI, Studio and local execution are free and open source. The hosted device cloud is 250 USD per device per month.

Adjust: How does it compare with AppsFlyer on price?

Generally more flexible for mid sized advertisers. Compare module scope, not headline rates, because attribution alone is rarely what you need.

Maestro: What exactly does per device mean?

It is a concurrency slot. One device runs one test at a time, so suite duration is a function of how many devices you buy.

Adjust: Can data be kept in the EU?

Yes, European hosting is offered, which is a common reason for choosing it over United States based competitors.

Maestro: How does it compare with Appium?

Tests are YAML rather than code and flakiness handling is built in, which reduces maintenance, at the cost of lower-level control.

Maestro: Can it test web applications too?

Yes, the cloud offers hosted web devices alongside Android and iOS, though the product centre of gravity is mobile.
