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

Buildkite

https://buildkite.com

GoCD

https://www.gocd.org
Unique feature

Runs on own infrastructure, API

Free, open source CI/CD server

Type of product

SaaS

On Premise

Offers a free plan

Yes

Free for open source projects and selected organizations

Yes

Free, open source software. They provide some Enterprise add-ons and support at a cost though.

Predictable pricing

Yes

Clearly defined monthly and annual plans

Yes

For the Enterprise plans, they specify very clear tiers depending on the number of pipelines (directly correlated with the size of the organization)

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

Paid support available 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

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

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

Yes

They specify supporting tools like TLB (http://test-load-balancer.github.io/) which would require distributed builds.

Containers support / Build environment

Yes

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

Yes

Native Docker and Kubernetes 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

One of the greatest things about GoCD is their Value Stream Map which allows tracing every pipeline through every stage, from code commit, to testing and deployment. They also offer various dashboards for seeing status at a glance.

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

Yes

Yes

Allows managing users, assigning roles, and even defining user groups with specific rights for certain pipelines.

Self-hosted option

No

Yes

Hosted plans / SaaS

Yes

No

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

Fairly advanced support, from config files (YML, Groovy, JSON, etc) to API and UI interface for building and managing pipelines.

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

Wide array of plugins available: https://www.gocd.org/plugins/#artifact (although they seem to pride themselves on the fact that most common operations / needs are first class citizens, so no plugins needed)

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

Available via plugins, such as the Gem repository poller: https://www.gocd.org/plugins/#package-repo

Specific language support: JavaScript

No

Yes

Available via plugins, such as the npm repository poller: https://www.gocd.org/plugins/#package-repo

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

Integrations are also available via plugins (for notifications, LDAP authorization, Elastic agents and more): https://www.gocd.org/plugins/#notification

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

You can build on top of GoCD in a variety of ways, from writing custom plugins to using the CCTray feed provided by it.

Auditing

Yes

Yes
