Unique feature

Customization

Security / speed

Type of product

SaaS / On Premise

SaaS

Offers a free plan

Yes

The cloud version is free for open source projects. Also offers a free plan for any project, with a limit of 5000 builds per year. The on-premise version is available as a Docker image.

Yes

Google offers a generous 120 build-minutes per day plan, not including time spent waiting in the queue.
Predictable pricing

Yes

Predictable pricing based on number of users and repositories. They have a calculator to help determine cost.

Yes (partial)

While it's clear what the cost is (priced per build-minute), figuring out costs can be a hassle, especially as the price can vary quite a bit depending on commits to the project.
Support / SLA

N/A

It's not clear what their support commitment is. They have a fairly active community on Discourse, for community support.

Yes

Even available as a paid add-on, for 24/7 phone support for example: https://cloud.google.com/support/
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 optimal way with Knapsack Pro

Yes

Pipeline task configuration allows running tasks in parallel

Yes

Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in optimal way with Knapsack Pro

Yes

Pipelines can be configured to run on multiple machines, although they recommend that to be an option only if paralellizing tasks and scaling vertically doesn't suffice. They even support multi-platform distribution (ie: running tasks on various operating systems)

N/A

Containers support / Build environment

Yes

By default, they offer Docker support for the CI/CD job runners.

Yes

Native Docker and Packer 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

Yes

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

Yes

They offer in-depth documentation for user and server management. A lot of it can be done via the drone CLI tool, which seems to be the focal point of the docs.

Yes

Self-hosted option

Yes

No (partial)

While there's no self hosted variant, they provide a local Cloud Build image which allows you to build locally, very valuable for debugging.
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

Easily configurable pipelines via YML files.

Yes

Configurable via YML and/or JSON 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?

Yes

Drone CI allows integrating plugins into the CI/CD process. They have a list of available community plugins and provide documentation on building your own. Plugins are Docker containers which plug directly into the CI/CD process.

Yes

There are predefined images built for Cloud Build, which can be integrated right away in your build process. Some of them are first party: https://github.com/GoogleCloudPlatform/cloud-builders and others are community contributed: https://github.com/GoogleCloudPlatform/cloud-builders-community
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.

No (partial)

No specific support, but they do provide sufficient documentation on getting a Ruby project up and running, including a multi-platform example.

N/A

Nothing specific as far as we can tell
Specific language support: JavaScript

No (partial)

No specific 1st party support, but the plugin marketplace features an NPM authoring and an NPM authentication plugin.

Yes (partial)

npm, yarn and jasmine-node support via predefined Cloud Build steps.
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

Integrates well with source code management platforms (1st party support for GitHub, GitLab, BitBucket) as well as other systems via 3rd party plugins.

Yes

Various integrations available via custom Build Steps, as well as natively (Kubernetes, Docker, etc.)
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

Drone provides a feature-rich REST API, as well as an official Go SDK for it.

Yes

REST API and comprehensive CLI tool, as well as a pub/sub system for build notifications.
Auditing

Yes

Yes

Additional notes

The fact that Drone works with any source code manager, as well as the fact that it can run tasks on multiple platforms makes it stand out from the rest. Very nifty!

Not unlike other Google tools, there's a strong emphasis on allowing developers to build on top of the service. Becomes more valuable if you're using other Google Cloud services as well.

How to run parallel tests on Drone and Google Cloud Build
to execute 1-hour test suite in 2 minutes?

How it works

1. Install Knapsack Pro client in your project


2. Add Knapsack Pro client to your current CI server and run your tests in parallel



3. Update your CI server config file to run tests in parallel with Knapsack Pro

Knapsack Pro in Queue Mode will split tests in a dynamic way across parallel CI nodes to ensure each CI node finish work at a similar time. Thanks to that your CI build time is as fast as possible. It works with many supported CI servers.

Features that make your tests perform better

  • Queue mode see video

    Dynamic tests allocation across Drone and Google Cloud Build parallel jobs. Autobalance tests to get optimal test suite split betweeen CI nodes.

  • Regular mode see video

    Test suite split based on time execution. Generates subset of test suite per CI node before running tests.

  • Fallback mode

    Network issues? Not a problem, run tests anyway! Auto switch to the fallback mode to not depend on Knapsack Pro API.

  • All supported test runners

    Ruby: RSpec, Minitest, Test::Unit, Cucumber, Spinach, Turnip.

    JavaScript: Cypress.io, Jest

We've been really enjoying Knapsack Pro, it's been saving us a ton of time.

Devin Brown Software Engineer at Pivotal

This is a fantastic product, it's been a total game-changer for us.

Geoff Harcourt CTO at CommonLit

We are using CircleCI and we noticed that builds were being limited by the slowest parallelized container. Knapsack Pro was really east to setup and we saw huge improvements right away. Thank you for making this tool!

Martin Sieniawski Software Engineer at Collage

Knapsack Pro has helped us build an insanely fast and scaleable build pipeline with almost no setup or maintenance.

Tim Lucas Co-founder of buildkite.com

Knapsack Pro saves us hours of engineer waiting time every week, and is the best solution for keeping our tests load balanced that we've used to date.

Michael Amygdalidis Senior Software Engineer at Popular Pays

I just logged into my account expecting it to say that I needed to add a credit card and was so surprised and delighted to see the trial doesn't count usage by calendar days but by testing days! This is incredible! I love it!!!

I just wanted to say that I really appreciate that small but very huge feature. Thank you for being so thoughtful :)
