About OpenTofu
OpenTofu is an open source infrastructure as code tool. It is a fork of Terraform and works as a drop-in replacement, so existing configurations and workflows carry over.
What it does
You describe cloud resources such as storage buckets, DNS records and code repositories in configuration files. OpenTofu then plans the changes and applies them, so your infrastructure can be tracked in version control. It uses providers for each cloud or service, and the project lists a large registry of providers and modules that you can reuse.
Key features
- Plan changes before applying them
- Providers for major clouds and services
- Reusable modules from a shared registry
- Exclude chosen resources from a plan
- Works with existing Terraform configurations
Who it's for
DevOps and platform engineers who manage cloud infrastructure and want an open source tool with a Terraform-compatible workflow.
Pricing and good to know
OpenTofu is free and released under the Mozilla Public License 2.0. The project is under the stewardship of the Linux Foundation, as its website states. Cloud accounts and any hosted services you add on top are billed separately by their own providers.
Highlights
