Sidekiq & Rails Compatibility Table
This article shows the compatibility between Sidekiq and Rails across different versions. Even though Rails is not a dependency of Sidekiq, there are compatibility considerations for different combinations given that Sidekiq provides integrations with Rails.
If you need help with Sidekiq’s compatibility with Ruby, check this other article instead.
Rows highlighted in red, below, indicate Rails versions that have reached the end of their security support.
| Rails Versions | Sidekiq Version |
|---|---|
| 8.x | >= 8.0.0 |
| 7.x | >= 6.5.10 and >= 8.0.6 |
| 6.x | >= 6.0.0 , < 8.0.0 |
| 5.x | >= 3.2.6 , < 7.0.0 |
| 4.x | >= 3.0.0 , < 6.0.0 |
| 3.x | >= 1.0.0 , < 5.0.0 |
| 2.x | No sidekiq version supports Rails 2 |
The information in this table is based on learnings collected during upgrades and also on proof found in the code and official statements of supported versions. Some versions out of the ranges shown here may still work in particular cases depending on the features used by a given application.
To check Sidekiq’s changes through releases, you can check Sidekiq changes document in their GitHub repository.
Sidekiq-Ent and Sidekiq-Pro
These gems are private so we can’t inspect all versions to create a similar table, but we recommend checking Sidekiq’s docs which, in some cases, may define supported versions of Rails and Sidekiq (though not consistently).
Another consideration to keep in mind is that Rails 7.1 adds the connection_pool gem as a dependency . When this happens, if not limited (which is the default), Bundler will resolve to version 3 of this gem, but Sidekiq-Ent only adds support of connection_pool 3 in version 8.1.0 . Note that this does not mean that older versions of Sidekiq-Ent are not compatible with Rails 7.1+; limiting the version of connection_pool to < 3.0 will also solve the incompatibility.
