In their own words
AppVeyor
AppVeyor provides continuous integration tools for Windows developers, with hosted service, self-hosted jobs and an Enterprise installation option for customer premises. A build pipeline can retrieve code, restore caches, install dependencies, build and test software, package artifacts, deploy, then run finalizer scripts. Projects can be configured through an appveyor.yml file or the user interface. Build matrices can create jobs across operating systems, variables, platforms, configurations, test categories and build clouds. Listed source control providers include GitHub, Bitbucket, GitLab, Azure DevOps, Kiln and Gitea. Deployment options include inline providers and environments triggered manually or through the API. The REST API covers teams, projects, builds, environments and deployments, with bearer-token authentication. Secure variables can be encrypted with account-specific keys and are not decoded during pull-request builds by default. Hosted builds use pristine virtual machines not shared with other builds, and VM state is not preserved. Every plan has a 60-minute maximum build-job execution time. Paid plans start at $29 a month.
Semaphore
Semaphore is an AI-native CI/CD platform for building, testing, releasing, and deploying code. Teams organize automated development tasks into workflows containing one or more pipelines. Its visual Workflow Builder represents pipelines, creates YAML configuration, and displays performance feedback. Repositories can connect from GitHub, GitLab, or Bitbucket. Teams can use hosted jobs or run self-hosted agents on Linux, macOS, or Windows; those agents can autoscale with Kubernetes or AWS. Semaphore is open source under Apache 2.0 and can be self-hosted. The default concurrency is 20 jobs, with higher limits available on request. Artifact use is free up to 20 GB monthly egress and 100 GB monthly storage; additional usage is charged separately. A free plan includes account, project, and Git integration assistance, while advanced CI troubleshooting is offered through paid support. Listed paid support begins with Basic Support at $50 a month. Semaphore says data is encrypted in transit and at rest, and that it holds SOC 2 Type 2 and ISO 27001:2022 certifications. Pricing includes free usage credits and per-minute compute charges.
