Buildkite vs Shippable comparison of Continuous Integration servers
What are the differences between Buildkite and Shippable?

Buildkite

Shippable

https://www.shippable.com
Unique feature

Runs on own infrastructure, API

N/A

Type of product

SaaS

SaaS / On Premise

Offers a free plan

Yes

Free for open source projects and selected organizations

Yes

Free unlimited builds for open source projects, 150 builds per month for all others (hosted plan). For the on-premise solution they only offer a 30 day trial.

Predictable pricing

Yes

Clearly defined monthly and annual plans

Yes

Clear pricing based on number of concurrent jobs. They also allow a varied combination of platforms you want to run (Ubuntu, Windows, MacOS, CentOS) and provide a Bring Your Own Node option (so you can run builds on your own infrastructure)

Support / SLA

Yes

Depending on the plan, ranging from community support, all the way to an assigned Technical Manager, SLAs and live chat support.

Yes

One of the few competitors to offer support tiers with clearly defined SLAs: https://www.shippable.com/premium-support.html as well as Services and Training: https://www.shippable.com/devops-services.html

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

Run an unlimited number of concurrent agents, and an unlimited number of concurrent jobs. You can run your tests in isolated Docker container per agent.

Yes

One thing that stands out, is the shipctl CLI tool, which can automatically determine which tests to run in parallel, based on previous performance, such that a minimal amount of time is ensured: http://docs.shippable.com/ci/running-parallel-tests/#running-tests-in-parallel

Distributed builds
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

Run an unlimited number of concurrent agents, and an unlimited number of concurrent jobs

N/A

No specific mention. From the wording, multiple environments are certainly available, but it's unclear if the tasks can be distributed to multiple containers/VMs on the same machine, or multiple machines.

Containers support / Build environment

Yes

Since the agents run on your own infra, you're free to do whatever

Yes

Native Docker support

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

The Buildkite UI features great vizualisations that feature build times, error rates, and more.

Yes

Detailed statistics available at multiple levels (job, account, project, etc.). They also include a view they call SPOG (Single Pane of Glass) which allows viewing a real-time representation of all of the pipelines in the organization, from where you can drill-in to the leaf nodes you're interested in.

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

Yes

Yes

Self-hosted option

No

Yes

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

Pipelines are defined using an Yaml config file and allow for great flexibility in defining what each step of the process does.

Yes

Configurable via an YML file (called Assembly Lines)

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.

Yes

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?

Yes

Integrations for GitHub, GitLab, BitBucket as well as SSO support (Google Suite, SAML, GraphQL API). Growing number of community plugins: https://buildkite.com/plugins

Yes

https://www.shippable.com/integrations.html

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

You can find useful plugins like https://github.com/sj26/rspec-buildkite https://github.com/ticky/simplecov-buildkite etc

Yes

Ruby is available by default on the Shippable container images. They also provide support for tools such as Cucumber or RSpec. Specific documentation for Ruby available on the website: http://docs.shippable.com/ci/ruby-continuous-integration/

Specific language support: JavaScript

No

Yes

Specific documentation for Node.js available: http://docs.shippable.com/ci/ruby-continuous-integration/

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

Yes

Integrations for GitHub, GitLab, BitBucket as well as SSO support (Google Suite, SAML, GraphQL API)

Yes

http://docs.shippable.com/ci/ruby-continuous-integration/

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

Yes

Great GraphQL API, allows building your own dashboard with ease

Yes

Provides a straight-forward REST API: http://docs.shippable.com/platform/api/api-overview/. They also provide ways to integrate notifications in your workflow, via webhooks or specific channels (IRC, Slack, Email, etc): http://docs.shippable.com/ci/send-notifications/

Auditing

Yes

Yes
