Scrutinizer CI vs AppVeyor comparison of Continuous Integration servers
What are the differences between Scrutinizer CI and AppVeyor?

Scrutinizer CI

https://scrutinizer-ci.com

AppVeyor

https://www.appveyor.com
Unique feature

Ongoing statical analysis

Supports NuGet packages / Windows build environment

Type of product

SaaS

SaaS / On Premise

Offers a free plan

Yes

Free for open source projects

Yes

Free SaaS plan for open source projects. There is also a free on premise version, but it's quite limited (1 user, 1 team, community support)
Predictable pricing

Yes

Three different paid monthly tiers

Yes

Very simple pricing plans: 3 options for the SaaS version, two options for the on premise option. No variable pricing.
Support / SLA

N/A

Not specifically mentioned, probably not.

Yes

All paid on premise plans offer support, as well as the two higher priced SaaS plans. Only community support available for the free on premise version and the lowest SaaS tier.
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

Automated parallalelization for code analysis, as well as support for running tasks in parallel

Yes

Allows splitting tests to run on different VMs in parallel.
Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines

N/A

Unclear from the documentation (probably not)

N/A

Containers support / Build environment

Yes

Tests run in isolated containers. Docker support available.

Yes

Runs every build in a VM, and it offers several options depending on the plan (SaaS or self-hosted) as well sa personal preference.
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

Besides classic CI overview, they also provide static code analysis insights, which is a differentiator for Scrutinizer

Yes

The dashboard is not as great as for other options in the market, but allows seeing project status at a glance.
Management support
How easy is it to manage users / projects / assign roles and permissions and so on

Yes

Additional seats available for every plan at $14.90 per seat, per month.

Yes

Allows creating teams and assigning roles. There is some integration with GitHub Teams but the concepts are different which might be tricky depending on how the GitHub project is managed, for instance.
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 as code (YML files)

Yes

There is a single predefined possible pipeline, which defines various hooks (such as before_build / after_build). The pipeline can be configured via the UI or via an appveyor.yml file. The two are mutually exclusive, so it's either one or the other.
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

Notifications are highly configurable, but visual reports such as code coverage is not easy to implement.
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?

No

N/A

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

Code analysis (automated code reviews) are available for Ruby, as well as specific documentation for setting up a Ruby project: https://scrutinizer-ci.com/docs/guides/ruby. Frameworks like Ruby on Rails are supported. They also provide tools like bundler-audit, for identifying vulnerable gems: https://scrutinizer-ci.com/docs/tools/ruby/bundler-audit/

Yes

Many Ruby gems use AppVeyor as their CI server of choice. Among the features for Ruby are the pre-installed Ruby versions on both Windows and Ubuntu servers, as well as the appveyor-worker gem which makes it easy to report status during the build process.
Specific language support: JavaScript

Yes

Automated code reviews are available for Javascript as well as specific documentation for setting up a Node.js project: https://scrutinizer-ci.com/docs/guides/javascript. Typescript is also supported.

Yes

Comes with node.js and io.js versions pre-installed. Also offers documentation on npm integration on their website.
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

Light integration with third party systems, mainly code management frameworks like GitHub, Bitbucket, GitLab.

Yes

Probably the most notable aspect here is the large array of deployment integrations available (from simple FTP uploads to Azure servers or NuGet packages).
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

Comprehensive REST API available: https://scrutinizer-ci.com/docs/api/

Yes

Offers a basic CRUD REST API for querying projects and builds as well as a real-time Build Worker API which can send updates on build status.
Auditing

N/A

Unclear from the documentation, but most likely available.

N/A

Additional notes

The code analysis features seem great, the offer for similar tools is quite light. Seems similar to lgtm.com

Very Windows oriented

How to run parallel tests on Scrutinizer CI and AppVeyor
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.

  • Queue mode see video

    Dynamic tests allocation across Scrutinizer CI and AppVeyor 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've been playing with Queue Mode. Love it! Wow, I love how fast it goes.

Michael Menne CTO at humanagency.org

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 :)
