What are the differences between Drone and Rancher Pipelines?

Drone

Rancher Pipelines

https://rancher.com/docs/rancher/v2.x/en/project-admin/tools/pipelines/
Unique feature

Customization

DevOps tool for container orchestration

Type of product

SaaS / On Premise

On Premise

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

Free, open source project

Predictable pricing

Yes

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

Yes

It's free!

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

Paid support available: https://rancher.com/pricing/

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

Pipeline task configuration allows running tasks in parallel

Yes

You can run multiple parallel steps within a build stage

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

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

Unclear from the documentation (probably not)

Containers support / Build environment

Yes

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

Yes

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

Not particularly clear, but it appears you can monitor stats in a Grafana dashboard: https://rancher.com/docs/rancher/v2.x/en/project-admin/tools/monitoring/

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

User management is available, with specific roles assigned, or permissions to certain resources and projects

Self-hosted option

Yes

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

Easily configurable pipelines via YML files.

Yes

Pipelines as code (YML files), but also manageable via the UI

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.

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.

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

Pipelines / CI is just a small part of Rancher. No specific support mentioned.

Specific language support: JavaScript

No (partial)

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

N/A

Pipelines / CI is just a small part of Rancher. No specific support mentioned.

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

Integrations available for GitLab, GitHub and Bitbucket

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 available. It provides introspection and documentation: https://github.com/rancher/api-spec/blob/master/specification.md#filtering. It should offer enough access to allow building whatever customizations or integrations with 3rd party tools deemed necessary.

Auditing

Yes

Yes

Allows logging to various systems (Kafka, Elastic, etc) which should make audit possible

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!

Rancher is a full software stack for container orchestration, going as far as building their own Linux distribution (RancherOS). Using Rancher seems more like a decision to be made considering all other features Rancher offers, not just the CI server. Also worth noting that Rancher uses Jenkins under the hood, but the engine is locked so projects can't just be migrated between the two.
