Travis CI

Verified Jul 2026

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.

Auth quickstart

  1. Sign up with the provider to get an API key.
  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.

Travis CI vs Azure DevOps Health

Despite its name, this is the Azure Resource Health control-plane API (part of Azure Resource Manager), which reports the real-time and historical availability status of individual Azure resources rather than anything DevOps-pipeline-specific. Every call goes through management.azure.com and is authenticated like any other ARM provider — a Microsoft Entra ID (Azure AD) OAuth2 bearer token in the Authorization header, not a plain API key. A live unauthenticated GET against its availabilityStatuses endpoint returned a structured JSON error with access-control-allow-origin: * rather than a raw connection failure, confirming the service and its CORS support are live.

Travis CI vs Bitrise

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 vs Buddy

Buddy's REST API manages its visual CI/CD pipelines end to end — projects, actions, environments, runs, sandboxes, and Git operations — and is described as covering the same permission model as the web app itself. Its docs state plainly that authentication is performed with OAuth2, sending requests with a Bearer access_token, which this run reconfirmed live: an unauthenticated call to api.buddy.works/user returned a 401 "Wrong authentication data" response while still carrying access-control-allow-origin: * on both the request and its OPTIONS preflight, resolving the previously unknown CORS support to open. Buddy's own pricing page lists a free plan (limited pipeline minutes and one seat) alongside paid Pro and Hyper tiers, making it freemium rather than a flat fee.
