The short version

  • Each has a real cost: Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month; 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: Bruno covers API Testing, 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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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.
