VP, Chief Enterprise Integration Architect at a financial services firm with 10,001+ employees
The biggest advantage is how simple the technology was.
I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Senior Cloud Engineer at a tech services company with 201-500 employees
Automation of cloud infrastructure has transformed how our team manages Terraform workflows
Spacelift has other features beyond Terraform, including Ansible, Pulumi, Terragrunt, and it also helps with Kubernetes, although we haven't used it for the other tools. We have only used it for Terraform Infrastructure as Code, and it has helped us significantly. One standout feature compared to Terraform Cloud is the ability to apply policies. For example, we want to restrict engineers in our team from building servers with a particular SKU, such as in Azure, where we do not want to run servers with a SKU higher than the standard D4sv5. We can apply those policies in Spacelift, and the RBAC and access policies features are really excellent in Spacelift, which we do not find in any of the other competitor tools. The pricing is also competitive compared to Terraform Cloud. The access policy features allow us to assign specific policies since we have three environments in our company: Dev, QA, and Prod. We assign policies so that anyone can run code from Dev and QA servers, but we assign a policy for specific people, such as managers, to run code in Prod. This is a very good feature from Spacelift that we have implemented for the access policy. Spacelift has positively impacted our organization as a CI/CD tool for application deployment and development. Although we use other CI/CD tools like Azure DevOps and GitHub Actions, there wasn't a specific tool for Terraform Infrastructure as Code until Spacelift came along. It allows us to easily configure our servers and build a number of them on our cloud. While other CI/CD tools have started to include configuration features, Spacelift offers many other benefits that make it an excellent tool to use.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"OpenLegacy opens the door to connect modern web products to our old legacy system."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."
"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."
"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."
"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."
"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"Knowing the HashiCorp Configuration Language (HCL) makes it easier to use without issues."
"Spacelift has positively impacted our organization because we do not have to detect drift or manage Terraform basics ourselves; Spacelift handles this for us with strong governance and security policies based on GitOps principles, which saves considerable time."
"Spacelift has positively impacted my organization in significant ways in terms of building infrastructure as code."
"I appreciate that I just have to connect to my AWS account with my credentials, and Spacelift handles the rest."
"Spacelift has positively impacted our organization by speeding up our deployments and easing a lot of pain with infrastructure deployments, especially because a lot of teams are working simultaneously on the same code base using the same configs."
"Spacelift has positively impacted my organization because it works well; it allows everybody to collaborate in the same Terraform repo without stepping on each other's toes."
"Spacelift has positively impacted my organization by reducing manpower, as it reduced the efforts of resources in the team, where previously a job done by two or three engineers can now be easily managed by one engineer using Spacelift."
"Spacelift is like an extension of Terraform, where everything can be visibly managed."
 

Cons

"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."
"I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"Debugging and logging for programmers could be better."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."
"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."
"Spacelift currently lacks features that can help with complex type deployments and coordination for major deployments."
"There are a few areas where there is room for improvement, particularly the initial setup and onboarding experience, which has a learning curve around understanding the concept of contexts."
"Spacelift is good overall, but there are little explanatory aspects, such as navigating particular stacks, that are somewhat difficult to understand for newcomers, especially regarding the process, stack setup, and variable setup for deployments."
"If I had to think of one area where Spacelift could improve, it would be the graph where we orchestrate, as the graph looks very complicated and complex, so perhaps it could be simplified."
"In the free version, there's no straightforward way to be notified once a deployment is finished."
"I think an improvement for Spacelift would be a feature to run multiple stacks."
"Perhaps the learning curve could be a bit steep if someone is completely new to Spacelift and only has experience with plain Terraform."
"Pricing could be a little lower to make it a very robust tool, and it can improve areas in scalability and integrate some open-source tools."
 

Pricing and Cost Advice

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"It is a bit expensive product."

What is your experience regarding pricing and costs for Spacelift?
My experience with pricing, setup cost, and licensing was that licensing was somewhat unclear when HashiCorp changed their own licensing.
What needs improvement with Spacelift?
It would be nice to have out-of-the-box A/B testing with Spacelift because we still use some custom features for that. Out-of-the-box A/B testing is the main thing I would like to add about the nee...

We manage a lot of AWS deployments with Spacelift configs, so we have a main use case for it. We also use it for versioning and spinning up new environments. Recently we used Spacelift for deployin...
