+# Dagger vs. Other Software
+
+## Dagger vs. CI (Github Actions, Gitlab, CircleCI, Jenkins, etc.)
+
+Dagger does not replace your CI: it improves it by adding a portable development layer on top of it.
+
+* Dagger runs on all major CI products. This *reduces CI lock-in*: you can change CI without rewriting all your pipelines.
+* Dagger also runs on your dev machine. This allows *dev/CI parity*: the same pipelines can be used in CI and development.
+
+## Dagger vs. PaaS (Heroku, Firebase, etc.)
+
+Dagger is not a PaaS, but you can use it to add PaaS-like features to your CICD pipelines:
+
+* A simple deployment abstraction for the developer
+* A catalog of possible customizations, managed by the platform team
+* On-demand staging or development environments
+
+Using Dagger is a good way to get many of the benefits of a PaaS (developer productivity and peace of mind),
+without giving up the benefits of custom CICD pipelines (full control over your infrastructure and tooling).
+
+## Dagger vs. artisanal deploy scripts
+
+Most applications have a custom deploy script that usually gets the job done, but is painful to change and troubleshoot.
+
+Using Dagger, you have two options:
+
+1. You can *replace* your script with a DAG that is better in every way: more features, more reliable, faster, easier to read, improve, and debug.
+2. You can *extend* your script by wrapping it, as-is, into a DAG. This allows you to start using Dagger right away, and worry about rewrites later.
+
+## Dagger vs. Infrastructure as Code (Terraform, Pulumi, Cloudformation, CDK)
+
+Dagger is the perfect complement to an IaC tool.
+
+* IaC tools help infrastructure teams answer questions like: what is the current state of my infrastructure? What is its desired state? And how do I get there?
+* Dagger helps CICD teams answer question like: what work needs to be done to deliver my application, in what order, and how do I orchestrate it?
+
+It is very common for a Dagger configuration to integrate with at least one IaC tool.
+
+## Dagger vs. Build Systems (Make, Maven, Bazel, Npm/Yarn, Docker Build, etc.)
+
+Dagger is complementary to build systems. Most Dagger configurations involve integrating with at least one specialized build.
+If several build systems are involved, Dagger helps integrate them into a unified graph.
