Type of product

On Premise

SaaS

Offers a free plan

Yes

They offer a great free professional plan, limited to 100 build configurations and 3 build agents. From there, you pay for each aditional agent you want (discounts if you purchase more than 1 agent at a time). They also provide a free plan for open source, non commercial projects, and steep 50% discounts for startups.

Yes

300 build minutes/month, 1 concurrent CI build

Predictable pricing

Yes

They have a clear list of prices per number of agents.

Yes

Extra 500 build minutes costs $7/month. User seat $15/user/month.

Support / SLA

Yes

Yes

99.99% uptime SLA for Starter and Pro plan. Business plan has negotiable SLA.

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

Yes

Starter plan (free) has only 1 concurrent build but Pro plan has 3 concurrent builds included.

Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines

N/A

No specific mention that we could find, but judging by the wording used it would appear that tasks can be divided accross different machines.

Yes

High-Performance Builds - The premium build environment gives more concurrency, processing power and asynchronous deploys.

Containers support / Build environment

Yes

First class Docker support, among others

Yes

When you trigger a build on Netlify, their buildbot starts a Docker container to build your website. The buildbot will look for instructions about required languages and software needed to run your command before running build command. The instructions are called dependencies, and how you declare them depends on the programming languages and tools used in build. Build image selection is available. Until recently, all Netlify sites were built using the same build image. Netlify is experimenting with allowing customers to select from multiple Docker images with different operating systems and software versions.

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

Great system overview, even allows building your own dashboards in order to see everything you're interested in at a glance.

Yes

Simple dashboard to see CI builds. Other than CI analytics Netlify has Netlify Analytics that brings data captured directly from their servers for your website.

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

Yes

Allows assigning roles, LDAP and Windows domain integrations and more.

Yes

Team members managment. Role-based access control only in business plan.

Self-hosted option

Yes

No

Hosted plans / SaaS

No

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

Unlike most options in the CI/CD space, TeamCity allows defining pipelines using a Kotlin-based DSL. This unlocks a lot of potential, such as templates for common CI/CD tasks, and deep integration with various IDEs (not just JetBrains IDEs)

Yes, partially

Simple steps, define your own steps in bash commands

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

Something that stands out from the rest, allows integrating third party reports, as long as they produce HTML output.

No

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

JetBrains has a rich ecosystem of plugins in general.

No

There are only small helpful things like incoming webhooks so other services can trigger Netlify deploys, and send outgoing webhooks as a deploy starts, succeeds, or fails.

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

Using what they call 'Technology Awareness', promises great intehration with Ruby projects, with features such as testing framework support, static analysis and code coverage available out of the box, with no additional work required: https://www.jetbrains.com/teamcity/features/technology_awareness.html

Yes

It has support for Ruby.

Specific language support: JavaScript

No (partial)

Unlike Ruby, there's no first class support for Javascript, although they do advertise the fact that their large collections of plugins can cover any use case for Javascript projects: https://plugins.jetbrains.com/teamcity

Yes

It has support for JavaScript.

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

Yes

Great cloud integrations (Google Cloud, AWS, VMWare, etc) as well as 'key' integrations (VSCode, Jira, even NuGet)

Yes

Netlify has incoming webhooks so other services can trigger Netlify deploys, and send outgoing webhooks as a deploy starts, succeeds, or fails. For instance you can integrate it with Slack.

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

Unlike most tools, which offer just a Rest API, TeamCity provides ample opportunity for extension via plugins, their own API, and service messages (formatted messages on stdout)

No

Auditing

Yes

N/A

Additional notes

Great ecosystem, with a strong focus on integration with other tools (not only JetBrains).
