How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Configuration management tools keep servers and infrastructure in a desired state, installing software, applying settings, and correcting drift automatically.
- Ansible is the best starting point for most teams because it is agentless and free, rating 4.8 out of 5 on G2, while Terraform rates 4.9 for cloud provisioning.
- Puppet and Chef lead for enterprise governance and compliance, with Puppet rating 4.7 and Chef 4.6, but enterprise pricing runs into five figures per year for 100 nodes.
- Terraform provisions infrastructure while Ansible configures it, so teams commonly use both together rather than choosing one.
- Licensing matters since 2023: Terraform uses BUSL 1.1, while OpenTofu offers an MPL 2.0 alternative for teams avoiding BUSL restrictions.

The best software config management solutions
#1Ansible
Best for: Agentless automation at scale4.6/5 on
G2 (377 reviews, checked Oct 2026)
Visit ansible.com
Starting priceFree
Free planYes
Ansible is the best starting point for most teams because it is agentless and free, using YAML-based playbooks that are easy to read and learn. Its agentless architecture means no software to install on managed nodes, which speeds adoption, and it runs on Linux, macOS, and Windows. The open-source engine is free, while Red Hat Ansible Automation Platform adds support, hardening, event-driven automation, and AI features for large enterprise teams, with a 60-day free trial.
The drawbacks are enterprise cost and enforcement style. Enterprise figures run near 10,000 dollars per year for 100 nodes in some comparisons, with Automation Platform from 3,000 dollars per year, and Ansible lacks the native continuous enforcement of Puppet. Ansible suits DevOps and sysadmin teams that want simple, agentless automation at scale.
What we like- Agentless architecture with YAML-based playbooks
- Free open-source engine supported by thousands of contributors
- 4.8 rating on G2
- 60-day free trial for enterprise platform

#5Terraform
Best for: Cloud infrastructure as code4.6/5 on
G2 (120 reviews, checked Oct 2026)
Visit terraform.io
Starting priceFree
Free planYes
Terraform is the default multi-cloud provisioning tool, creating servers, networks, and cloud resources as code across AWS, GCP, and Azure, with state and drift handling that previews changes before applying them. It rates 4.9 out of 5 on G2, the highest on this list, and its provider and module ecosystem is the broadest for cloud provisioning. Teams commonly pair Terraform with Ansible, since Terraform provisions infrastructure and Ansible configures the servers inside it.
The drawbacks are licensing and scope. Since 2023 Terraform uses BUSL 1.1 under IBM, which is not fully open source, and teams avoiding BUSL restrictions use OpenTofu under MPL 2.0 as an alternative, while Terraform alone does not configure servers inside provisioned resources. Terraform suits cloud infrastructure teams that need multi-cloud provisioning as code.
What we like- Multi-cloud provisioning across AWS, GCP, and Azure
- Infrastructure as code with state and drift handling
- 4.9 rating on G2, highest on this list
- Usage-based cloud pricing

Its ecosystem is newer than Terraform, team pricing rises to 2,000 dollars per month, and its infrastructure focus means server configuration depth trails Ansible and Puppet. Pulumi suits teams who want real programming languages for infrastructure as code.
What we like- Real programming languages instead of DSLs
- Apache 2.0 license
- Free plan available
- From 40 dollars per month up to 2,000 dollars per month for teams

How we chose
We compared configuration management tools on automation model, agent requirements, licensing, enterprise governance, and published pricing, using 2026 DevOps comparisons and G2 ratings. We favored tools with clear model positioning, whether agentless, model-driven, event-driven, or infrastructure-as-code, while noting where enterprise pricing varies widely across sources. We also flagged licensing changes, since Terraform BUSL versus OpenTofu MPL affects long-term choice.
How to choose the best-rated software config management solutions
Start by separating provisioning from configuration: Terraform or Pulumi provision cloud resources, while Ansible, Puppet, Chef, or Salt configure servers inside them, and most teams need both. Next, match the model to your team: Ansible for simplicity and agentless start, Puppet for continuous enforcement and compliance, Chef for policy-as-code with Ruby skills, and Salt for event-driven scale. Then check licensing, especially Terraform BUSL versus OpenTofu MPL, and confirm enterprise pricing for 100 nodes before committing, since figures range from 10,000 to 19,900 dollars per year. Finally, pilot with one environment and measure drift correction, since enforced desired state matters more than feature lists.
Frequently asked questions
What is configuration management software?
It is software that defines infrastructure as code, installs software, applies settings, and enforces desired state on servers, correcting drift when reality differs from code. It keeps large fleets consistent without manual changes per server.
Is Ansible really free?
Yes, Ansible open-source engine is free to use, supported by thousands of contributors, while Red Hat Ansible Automation Platform is the paid enterprise tier with support, hardening, event-driven automation, and AI features.
What is the difference between Terraform and Ansible?
Terraform provisions infrastructure: it creates servers, networks, and cloud resources. Ansible configures them: it installs software and settings inside those resources. Teams commonly use both together.
Which is better, Puppet or Chef?
Both are mature enterprise platforms. Puppet emphasizes continuous enforcement and compliance reporting, while Chef emphasizes policy-as-code and DevOps workflows. Evaluate both against your team skills and audit requirements.
Do I need configuration management if I use Docker and Kubernetes?
You need less of it, but you still need it. Containers reduce server-level configuration, but hosts, networks, and non-containerized systems still drift. Many teams use Terraform and Kubernetes for new workloads and Ansible or Puppet for what remains.
Is Salt still maintained after the Broadcom acquisition?
Yes, the Salt Project continues as an open-source project with documentation, releases, and a community. Broadcom owns VMware, which stewards Salt, so evaluate the roadmap accordingly before committing.
