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.; WebdriverIO its lead maintainer's day job and the project's most visible sponsorship both sit with Sauce Labs, a closer single-vendor tie than some other OpenJS projects, worth weighing for teams that specifically want vendor-neutral tooling.
  • They diverge on capability: Kong Gateway covers API request routing, WebdriverIO covers WebDriver and BiDi protocol support.
  • Prices and features above were last checked on 1 September 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.

WebdriverIO

  • Its lead maintainer's day job and the project's most visible sponsorship both sit with Sauce Labs, a closer single-vendor tie than some other OpenJS projects, worth weighing for teams that specifically want vendor-neutral tooling.
  • Playwright has captured much of the newer end-to-end JavaScript testing mindshare, so WebdriverIO's plugin ecosystem and community size, while real, are smaller than Playwright's.
  • The dual protocol support for both classic WebDriver and WebDriver BiDi adds real configuration complexity for teams that just want one straightforward automation path.
  • Documentation and community answers assume a working knowledge of WebDriver concepts, so teams new to browser automation face a steeper ramp than a more opinionated, simpler framework.
  • As with other OpenJS-governed projects, there is no vendor SLA or paid support tier for the framework itself, only for the commercial device clouds it integrates with.
