The short version

  • Each has a real cost: 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.; WSO2 API Manager the free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • They diverge on capability: Maestro covers YAML test flows, WSO2 API Manager covers API Gateway.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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.

WSO2 API Manager

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately

Answered from the vendors’ own pages

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.

WSO2 API Manager: How is WSO2 API Manager priced?

WSO2 API Manager pricing is not published on their website. As an enterprise API management platform, pricing is custom-quoted based on deployment model and organizational requirements.

Source
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.

WSO2 API Manager: Does WSO2 API Manager offer different pricing for on-premises versus cloud deployments?

WSO2 API Manager supports multiple deployment options including on-premises and cloud, but pricing structures for different deployment models are not publicly disclosed.

Source
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.

WSO2 API Manager: What deployment flexibility does WSO2 API Manager provide?

WSO2 API Manager enables flexible deployment on-premises or in cloud environments, but specific pricing tiers for each deployment model require contacting WSO2 sales.

Source
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.

WSO2 API Manager: How would I request a WSO2 API Manager pricing quote?

Organizations can request pricing quotes by contacting WSO2 sales through their website. Custom quotes depend on API volume, deployment model, and feature requirements.
