Spacelift goes beyond the basics of managing the lifecycle of OpenTofu and other IaC tools by adding useful constructs like spaces, contexts, and integrations that make managing a large number of configurations a scalable process. The web user interface is basic, but gives easy access to all the key information One thing that really impressed me is the quality of the integration with GitHub repositories. Spacelift not only runs OpenTofu plans automatically for pushes and pull requests, but does so without any manual configurations or boilerplate workflows in the repositories. It also handles monorepos really well, only running plans only for stacks that are actually affected by changed files. And, it's possible to promote proposed changes all from within GitHub. The spacectl CLI is similarly well integrated, making it easy to integrate into local development workflows.

Lots of flexibility - integrate with your workflows without needing to change them. Great collaboration features like pull request previews, access levels, change approvals, and more.

I love how Spacelift allows our small team to efficiently manage a large number of stacks, enabling us to configure and manage our infrastructure in a clean and sensible way. The simplicity of configuring Terraform through Spacelift is particularly impressive, as it streamlines our process and allows us to manage infrastructure dependencies smoothly. I appreciate the systematic and repeatable way it facilitates the rollout of applications and infrastructure, which is crucial for maintaining our operations. Additionally, the easy initial setup and the ability to write our own modules quickly were extremely beneficial. The support from Spacelift has also been exemplary, with their team providing substantial help during the setup process through calls and hands-on assistance, ensuring we could address any problems effectively. Being a long-time user, the consistency of their support over time has made our experience with Spacelift very positive.
