What is the best alternative to Concourse CI?
Pro Free for open source projects
Travis is free for all public repositories on Github.
Pro Easy to set up and configure
All that is needed to set up Travis is a configuration file (travis.yml) in the root of the repository where it will be installed and Travis takes care of the rest.
Pro Github integration
Travis registers every push to GitHub and automatically builds the branch by default.
Con Only GitHub support
It does not support BitBucket. So it's not in list for companies using BitBucket private or public repositories.
Con Non-free for private repos
Travis CI was first built to serve and help Open Source Projects, but now they also have added support for Closed Source which unfortunately is not free.
Con Relatively expensive
Commercial plans for Travis are relatively expensive compared to other tools. They start at $129/month.
Pro Free and open source
Jenkins is a free and open source continuous integration tool, while its source code is hosted on GitHub.
Pro Highly customizable
Even though Jenkins is pretty functional and useful out of the box, there's a large plugin ecosystem from which the user can choose plugins to integrate into their Jenkins build. This is needed for when the user wants to extend any of the tool's features.
Pro Safe to store key environment variables
Self-hosting provides a safe location to store key environment variables since it is the user who is in charge of the server and environment where Jenkins is hosted.
Con Poor quality plug-ins that are difficult to combine
There have been several complaints by users regarding the quality of the plug-ins found in Jenkins' official plugin repo. A lot of plugins found in the default plugin directory are no longer actively maintained and as a result, they may be incompatible with later versions of Jenkins or other pl...
Con High overhead
Unlike some of the simple and hosted alternatives, users need to host and setup Jenkins by themselves. This results in both a high initial setup time, as well as time sunk into maintenance over a project's duration.
Con Unstable and lack of plugin integration QA process
Jenkins without plugins is almost useless. All plugins are treated equal and published almost right away. Because there is no process for testing Jenkins' integration, the overall Jenkins experience is not that great. Furthermore, Jenkins' core and plugins are released on a regular basis,...
Pro Ability to create and use custom environments
Wercker is based on Docker and it allows developers to create their own deployment stacks inside Docker containers. These stacks range from programming languages, to services, and even to notifications.
Pro Free unlimited number of private repositories CI while in Beta
While in beta, Wercker offers unlimited free public and private repositories.
Pro Social networking elements
Wercker has an activity feed with which different team members can see and follow everything their colleagues have been doing. This gives the tool a certain social network feel, much like GitHub itself.
Pro Good traceability of what contributed to a given artifact
GoCD's LEAN value stream UI helps all stakeholders focus on efficient product delivery (instead of collections of technical tasks).
Pro Native support for pipelines
GoCD supports pipelines natively. This way you can build your projects by pipelining them.
Con Need Scripts for everything
Almost all operations are shell based, they are not configurations possible, your CI is as good as your scripting
Con Does not offer many plugins
Since it's relatively new and not very popular, there are few plugins available in GoCD.
Pro GitHub and Bitbucket integration, also supports other Git services
Webhook server is also open source.
Pro Visual configuration editor
The configuration can be specified without the need to change the code repository
Pro Builds are faster
The fact that Shippable runs inside of Docker means that it keeps a persistent state and every build will not have to revert to initial state where it needs to install every dependency from the ground up. Classic CI tools that run on virtual machines need to reset their environment every time and e...
Pro GitHub and Bitbucket integration
Shippable supports both BitBucket and GitHub. Repositories uploaded on either of those services can be built using Shippable.
Pro Free plan available
Unlimited builds for unlimited public repos and up to 5 private repositories.
Con Requires way to much permissions when logging in using Bitbucket
It even requests the permission to "Delete your repositories".
Con No Direct Deploy to S3
Currently, Shippable does not allow for build artifacts to be natively deployed to S3. This can be gotten around, however it is a rather large hole when compared to Travis. In order to deploy to S3 you have to add a couple of lines to the yml file. For example: env: global:#secure variable...
Con Docker security measures may be a hindrance
Shippable runs inside Docker containers. Docker has some specific security measures which may or may not become a hindrance in using Shippable. It may be harder for users who are not very comfortable with a Linux container environment and that can create some security problems. Even for more advanc...
Pro Extremely fast parallel testing
Solano CI offers safe parallel execution and dynamic task distribution which finish builds automatically and up to 80x faster.
Pro Excellent customer support
Solano CI offer highly-responsive customer support, while extensive documentation and tutorial materials help customers keep Solano CI running in optimal condition.
Pro CLI interface
Solano CI has a CLI interface available, making it less time-consuming to work with and allowing for remote usage over the internet.
Con No free OSS plan.
There is only a 14-day free trial available for Solano CI.
Pro Free for open-source projects
AppVeyor is free for public GitHub repositories.
Pro Clear, straight-forward user interface
Well I suggest you check it out for yourself, but what I like most is that it's simple yet effective: no bells and whistles, simple black/grey/light-blue/white color scheme, it's immediately clear where you have to go for each specific task, and build settings pages are like that as well. G...
Pro Easy access to build VM
AppVeyor allows the user to login to the actual build VM.
Con Not free
This is open-source but not free.
Con Configuration is limited
AppVeyor's configuration (which is done from the .yaml file in the root of the project) is unfortunately very limited. The configuration is either tied to a branch or, in other cases, it's global. This limits the developer to a single build process. However, since you can use arbitrary scr...
Pro Provides time taken for each step
Eg: ./1.setup.sh 48s ./2.build.sh 56s With this information, it's easy to find out which line of the script is the bottleneck of the build process.
Pro Great Jira integration
The same company Atlassian built Jira, which provides top-tier integration with Jira.
Con Only 50 mins/month free usage
The Free plan only gives you 50 minutes per month to run the build.
Pro GitHub integration
Projects can be imported from GitHub and Semaphore will automatically connect with that repository, once that's done, it will automatically trigger for every code commit.
Pro Complete customer support
Semaphore offers all-around customer support for its commercial users.
Pro Free for open source
Semaphore supports open source and offers unlimited open source projects.
Con Proprietary with private project for $30/month
Semaphore is not free and nor is it open source. Pricing starts at $29 per month. However, there is a free option for private projects which have less than 100 builds per month and it's free for open source projects.
Pro Fine-grained control over each environment the project needs to be deployed to
Bamboo is the only build server to offer first-class support for the "delivery" aspect of continuous delivery. Deployment projects automate the tedium right out of releasing into each environment, while letting you control the flow with per-environment permissions.
Pro End-to-end visibility when linked to JIRA, Stash and HipChat
When connecting Bamboo with Stash and JIRA, details like JIRA issues, commits, reviews and approvals follow each release from development to production. If HipCHat is part of the integration, team members get notified right away in addition to email notifications.
Pro Integration with Docker
Bamboo allows using Docker containers to create build agents. Using Docker agents lets you run multiple remote agents on the same host without conflicting requirements. It makes it easier to duplicate and distribute changes to build agents, and to use scripts for creating and maintaining agents....
Con Very limited basic license.
Although they have $10 license it is very limited even for modest shops. Even next step of commercial license is very expensive for what you get.
Con Bamboo Cloud is going away in Jan. 2017
Migration to Bamboo Server is non-trivial and may not be worth the effort.
Con Free open-source require application to use
Bamboo does offer a free option for open source projects though it requires the user to apply for it in order to use it past the free trial.
Pro Integrated with GitHub, BitBucket, and Google Code
Drone.io integrates perfectly with GitHub, BitBucket and Google Code.
Pro Docker integration simplifies deployment
Drone uses Docker containers to build and test code. Using Docker containers makes it easier for developers to then deploy this code to production.
Pro Easy self-hosted setup
Drone can be easily set up locally: all that's needed is Docker.
Con Does not allow you to configure two projects using the same GitHub repo
Drone.io does not let developers configure two different projects against the same repository. Instead, one must fork that repository into a new one and use that to create a new Drone.io project.
Pro Free private repositories
Private repositories are free. Although they are free for up to 3 repos and each repository must be less than 100MB in size.
Pro Nice material design
The design is minimalistic and based on today's standarts on material design. It uses colors which are pleasing to the eye and displays the information in an ordered way. The main view shows the latest activity sorted in a chronological order, displaying commits and pushes. Every repo has it&...
Con Unlimited private repositories are not free
To have more than three repositories and to bypass the limit of 100MB per repository it's not free. It costs $3/month.
Pro GitHub & Bitbucket integration
Support for public and private GitHub and BitBucket repositories. It also has support for multi-user teams.
Pro Headless browser support
Alongside latest Chrome and Firefox, Codeship supports the use of Selenium, PhantomJS, CasperJS as well as tools like Capybara.
Pro Build status GIF
There's a continuously updated GIF of the build status of the repository allowing you to determine whether build was successful or not.
Con Too many permissions on Bitbucket
When registering with Bitbucket Codeship it requests way to many permissions, even "Read and write to your team's projects and move repositories between them". Before giving all these permissions you have to be sure you can trust this service.
Pro Can deploy to any server, on any platform
Distelli suports all of the popular platforms and can be deployed to any server.
Pro Allows tracking deployments
Through Distelli, the user can track who deployed what application to what environment, as well as when it happened.
Pro Environment-specific commands
In Distelli, the user can set up environment-specific commands to run before, during, or after a deployment.
Con Security concerns
Although Distelli is very easy to use and helps developers who don't want to spend time setting up their build environment, there are a number of security concerns regarding the tool. This is because you have to host an agent that allows RPC with a relatively unknown third party.
Pro Very fast parallel testing
Tests can be parallelized across multiple machines reducing test times drastically. They support up to 8-way parallelization. Additionally, CircleCI caches the build environment.
Pro Quick setup
CircleCI excels with its setup process. All that's needed is a GitHub login and CircleCI automatically detects the settings for Ruby, Python, Node.js, Java and Clojure. The setup process is their most widely praised feature.
Pro Simple and intuitive GitHub integration
CircleCI can be connected to any project that is hosted on GitHub by logging in using the GitHub OAuth and adding the desired repository. Whenever a new commit is pushed to GitHub, CircleCI runs the tests that have been already defined and if none of them fails, the build is deployed to the runti...
Con Changes the environment without warning
Unless you count forum posts as a warning. A mysql upgrade caused days of debugging.
Con Does not cache docker images
The way to fake it is to save the image on disk, in the cache folder (it tars it), and restore it afterwards. But in tests it was slower than not caching.
Con Docker is way outdated on the VM provided
Currently (October 5th 2016), Docker installed on the VM is: 1.9.1-circleci-cp-workaround, build 517b158, and docker-compose is 1.5.2, build 7240ff3. docker-compose in particular is almost too old to be used.
Pro Free and open source
All of GitLab CI's code is open source and under the MIT license.
Pro Parallel builds lessen test times
Tests are parallelized across multiple machines in order to reduce test times considerably.
Pro Docker Intergration
Good integration with Docker.
Pro Easy installation
TeamCity has different installation packages for different operating systems. All the user needs to do is download the correct one and run it.
Pro Cross-platform build support
The fact that it is based on Java does not hinder TeamCity's ability to support different build environments. TeamCity in fact supports a large number of languages and tools for each of those languages (build runners and test frameworks). Some of the languages/platforms that are supported incl...
Con Expensive
TeamCity has a free tier which includes a maximum of 20 build configurations and up to 3 build agents. If you want to add 10 more configurations and 1 more agent, it will cost $299; unless you choose to buy an enterprise license which starts at $1999.
Con Inter-branch merges trigger emails to unrelated committers
Whenever an inter-branch merge occurs, TeamCity pulls up the first parent of the merge commit and sends them an e-mail. However, this sort of information would be more useful to the merge author.
Pro Very easy to set up
The web UI allows writing a build script inline, running a script from your repository, or creating a whole pipeline. Docker support is built-in.
Pro Intergrates with VCS
Integrates with GitHub, GitHub Enterprise, Bitbucket, Bitbucket Server, GitLab, Codebase, or any custom Git repository.
Pro Affordable
One plan that gives you everything at a reasonable price.
Pro Provides modules for changeable functionality
Snap provides "snaplets". These are self-contained modules of code that provide additional functionality without muddling the core library. Having these resources saves time when developing code.
Con Outdated documentation
The comprehensive Snap documentation is currently outdated (last activity appears to have been 2013), though Snap itself is under active development. Note that this primarily affects tutorials and guides; the API documentation is generated automatically and remains current.
