The short version

  • Each has a real cost: Kong Gateway the free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.; 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: Kong Gateway covers API request routing, Maestro covers YAML test flows.
  • 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.

Kong Gateway

  • The free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
  • Plus tier caps API requests at 1M/month before incurring per-million overage charges.
  • Enterprise pricing is custom and not published, making budgeting harder without sales contact.
  • Configuration and plugin management can require significant operational expertise to run at scale.

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

Kong Gateway: Is Kong Gateway free?

Kong's core gateway is open source and free to self-host. Kong Konnect, the managed cloud platform, offers a 30-day free trial before moving to paid Plus or custom Enterprise pricing.

Source
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.

Kong Gateway: How is usage metered on the Plus plan?

The Plus plan includes 1M API requests per month, with additional usage billed at $200 per extra 1 million requests up to a 10M/month cap, plus per-gateway and per-LLM-model charges.

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.

Kong Gateway: What support is included?

Plus includes email support with a 2-business-day SLA, while Enterprise adds dedicated success managers and professional services.

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.

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.
