Semaphore CI vs CodeFresh CI comparison of Continuous Integration servers
What are the differences between Semaphore CI and CodeFresh CI?

Semaphore CI

https://semaphoreci.com

CodeFresh CI

https://codefresh.io
Unique feature

Autoscaling made easy / Great CLI

Built for Kubernetes

Type of product

SaaS

SaaS / On Premise

Offers a free plan

Yes

1,300 service minutes every month. Plans to release a free tier for open source projects.

Yes

Offers a minimal free plan (only one concurrent job, 3 users, various other limitations)

Predictable pricing

Yes

Semaphore doesn't have traditional pricing tiers, instead it lists the types of machines you can use and their pricing per second of service. They plan to release an annual plan at some point.

Yes

Easy price calculator, based on the number of machines, concurrent jobs and special features.

Support / SLA

N/A

Not clear if they offer any real SLA on support.

Yes

Paid support for enterprise plans

Paralellism
Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in the optimal way with Knapsack Pro

Yes

Allows defining a custom build matrix such that your build can be parallelized accross several different environments.

Yes

Distributed builds

N/A

N/A

Unclear from the documentation (probably not)

Containers support / Build environment

Yes

Allows running builds inside docker containers

Yes

Built for Kubernetes, so containers are a must.

Analytics / Status overview
Analytics and overview referrs to the ability to, at a glance, see what's breaking (be it a certain task, or the build for a specific project)

Yes

Yes

They seem to provide pretty great status overview, depending on the type of plan you're using.

Management support
How easy is it to manage users / projects / assign roles and permissions and so on

Yes

Yes

Self-hosted option

No

Yes

Only available for enterprise plans

Hosted plans / SaaS

Yes

Yes

Build pipelines
A continuous delivery pipeline is a description of the process that the software goes through from a new code commit, through testing and other statical analysis steps all the way to the end-users of the product.

Yes

Allows defining complex build workflows with ease

Yes

Pipelines as code (YML files)

Reports
Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard.

N/A

Yes

Ecosystem
Besides the official documentation and software, is there a large community using this product? Are there any community-driven tools / plugins that you can use?

N/A

Yes

Every step in a CodeFresh pipeline is a Docker image. A wide array of steps is available over at https://steps.codefresh.io/

Specific language support: Ruby
Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those. Some others make it even easier by detecting Gemfiles or package.json and automate parts of the process for the developer.

Yes

Provides rich documentation on integrating Semaphore CI in Ruby projects. Also provides sudo access if you need to install system dependencies or C extensions.

Yes

Specific documentation for a sample Ruby-on-Rails project: https://codefresh.io/docs/docs/learn-by-example/ruby/

Specific language support: JavaScript

Yes

Provides rich documentation on integrating Semaphore CI in Javascript projects

Yes

There's an 'npm publish' step available, and they also provide a few Javascript examples over at https://codefresh.io/docs/docs/learn-by-example/nodejs/ (one is just a sample, one is a little more complex, using Redis, Python, etc., and one is a React App)

Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

Integration with GitHub and Slack. They allow building iOS projects via their macOS Mojave VM image.

Yes

https://steps.codefresh.io

API
Custom integreation is available, via an API or otherwise, it's mentioned separately as it allows further customization than any of the Ecosystem/Integration options

No

Yes

Rich REST API available, well documented at https://g.codefresh.io/api/

Auditing

Yes

Yes

Audit logs available: https://codefresh.io/docs/docs/enterprise/audit-logs/
