OpenTofu — open-source infrastructure as code for planning and applying declarative changes

About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

OpenTofu is an infrastructure-as-code tool for managing cloud and service configuration with declarative files, reviewing an execution plan, and then applying changes. It builds a dependency graph for resources and supports reviewable, repeatable infrastructure workflows. The source is published under Mozilla Public License 2.0.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Review proposed changes before applying them

OpenTofu generates an execution plan from configuration and current state so operators can inspect resource creates, updates, and deletes before apply.

Sources: [2]

Order infrastructure changes through a dependency graph

Resource dependencies form a graph, allowing independent operations to run in parallel while preserving required ordering.

Sources: [2]

For teams integrating IaC into Git review and CI

OpenTofu suits workflows where infrastructure configuration is shared and versioned, with plan output reviewed before changes are applied.

Sources: [2][4]

Evaluate provider and registry operations as part of adoption

Real deployments depend on providers, modules, and registry access in addition to the core CLI. The README explicitly marks nightly builds as experimental and unsuitable for production.
