Bitrise vs Travis CI

Bitrise's REST API drives its mobile-focused CI/CD platform: triggering builds, reading build and workflow logs, and managing apps, webhooks, and cache across a project's pipelines. A live unauthenticated GET against api.bitrise.io/v0.1/me returned a clean 401 Unauthorized JSON body while still carrying access-control-allow-origin: * on both the request and an OPTIONS preflight, confirming the personal-access-token auth model and resolving its previously unknown CORS support to open. Its own pricing page offers a free Hobby tier for individual developers alongside paid team plans, so this is a freemium product, not a flat-fee one.

Travis CI's REST API reads and manages builds, repositories, branches, and jobs, and its docs specify a token-based Authorization: token "<token>" header rather than an OAuth redirect flow, reconfirming the stored API Key auth model. A live GET against api.travis-ci.com returned a structured JSON response (not a raw connection error), and the same request sent with an Origin header carried access-control-allow-origin: * on both the GET and its OPTIONS preflight, resolving the previously unknown CORS support to open. Travis CI's own pricing page still lists an "Open Source Only" free tier alongside paid Linux/FreeBSD plans, so it remains freemium rather than fully paid.
