The policy-as-code engine is the standout feature for us — being able to define OPA-based policies to control who can approve and apply Terraform changes has greatly improved our governance over AWS infrastructure. Stack management is also solid, making it easy to organize and track deployments across multiple environments. The pull request preview feature is a big workflow win: engineers can see a Terraform plan directly in their PR before merging, which catches issues early and speeds up code review.

The documentation is the weakest area. For example, we struggled to find clear guidance on security best practices for setting up Spacelift across an org, specifically how to scope IAM permissions per stack so each stack has only the access it needs. This is a common requirement but the docs don't walk you through it in a practical way. Review collected by and hosted on G2.com.

I really like Spacelift for its price. I also especially appreciate having CLI access to integrate it with AI agents. I have a skill configured with the list of commands that the CLI allows, which lets me automatically validate changes when I submit a pull request. We replaced Terraform Enterprise with Spacelift because it was much more expensive, and I am satisfied with this change. Review collected by and hosted on G2.com.

Intuitive UI with commenting and ad hoc stack locking for collaboration. Great integration with Gitlab to see change summaries and links to runs. Review collected by and hosted on G2.com.

Tough question as the feature requests we’ve raised have been implemented! Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

The web interface is rather basic. It's focussed on one entity at a time (e.g., spaces, stacks, contexts), making it hard to get holistic views of things. For example, when I'm on the page for a space, I'd ideally like some sort of overview of the stacks and contexts in the space and drill down into them. Instead, I have to go to the stacks page and filter down to the space, the contexts page and filter down to the space, etc. There's also some rough edges and odd behaviours like action panels covering up lists, and weird list item selection behaviours.

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. Review collected by and hosted on G2.com.

I find it sometimes quite difficult to configure the things we need in Spacelift. The configuration process can be challenging, especially when adding new configuration items, as the context needs to exist with those items in it. This requirement is understandable but it can be a bit of a hassle and causes an overhead. Review collected by and hosted on G2.com.

Flexibility and deep orchestration power Review collected by and hosted on G2.com.

Limited and non-practical documentation for complex setups Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

The flexibility comes with complexity. It can be easy to build something too company or workflow-specific when you should instead take the opportunity to rationalise and simplify our processes. Review collected by and hosted on G2.com.

Delegation, I can delegate all Terraform actions - Infrastructure as a code to a dedicated place, important element state management, extremely easy to start the journey with Terraform (for example, to the people from Azure Bicep) Review collected by and hosted on G2.com.

Today I don't see any problems. Documentation and samples are clear Review collected by and hosted on G2.com.

Spacelift makes infrastructure management manageable, with its ability to use terraform or other infrastructure as code tools, spacelift feels like a must-have for any organization. Review collected by and hosted on G2.com.

I would like to see a little more controllability over the data we are storing. Though Terraform allows us to control the building and deployment of our infrastructure, I always worry about data that is exposed to the service provider. Review collected by and hosted on G2.com.

Spacelift has done a positive transformation to the way we manage our infrastructure. Now we have a tool with a lot of built-in guards so that developers are able to provision their infrastructure themselves, with minimal assistance from infrastructure engineers. This includes amazing integration with GitHub, tests, policies and everything is done as code. Review collected by and hosted on G2.com.

I wish Spacelift could grow faster in terms of features, since we rely on the tool more and more. Review collected by and hosted on G2.com.
