Pulumi has a lot going for it, especially if you’re someone who enjoys writing infrastructure with real programming languages. But let’s be honest, not every team wants to think in Python or TypeScript when all they really need is a couple of servers and a database spun up. Some folks want something lighter. Others prefer more guardrails. And a fair number just don’t have the energy for another tool in their already long list of DevOps responsibilities.
So if you’re curious about what sits alongside Pulumi in the IaC world, there’s plenty to explore. Every tool has its own personality. Some feel close to the classic template style many teams grew up with. Others lean hard into automation so you don’t have to babysit infrastructure yourself. The goal here isn’t to pick a winner. It’s to help you get a feel for what else is out there and maybe find something that actually matches the way your team likes to work.
1. AppFirst
AppFirst takes a very different route. Think of it as IaC without the IaC part. Instead of writing Terraform configs or YAML, you describe what your app needs, and AppFirst builds the environment for you. It wires together the usual stuff like logging, monitoring, and security policies while you focus on the app itself.
It’s the kind of tool that makes you feel like you suddenly got your weekends back. Everything keeps itself in shape, changes are tracked, and you even get cost visibility tied to each app. For teams that want less DevOps overhead and more shipping, AppFirst fits right in.
Wichtigste Highlights:
- Automatic provisioning based on app requirements
- Built-in logging, monitoring, and alerting
- Centralized change history
- Cost breakdowns by app and environment
- Supports AWS, Azure, and GCP
- Available as SaaS or self-hosted
Für wen es am besten geeignet ist:
- Teams that do not want to write or maintain IaC code

Schlussfolgerung
After looking at all these Pulumi alternatives, one thing becomes clear: there’s no single tool that works for everyone. Each one solves a different part of the infrastructure puzzle. Some focus on configuration. Others focus on automation. A few try to smooth out the entire workflow so you don’t have to juggle as many tools.
If you’re unsure where to start, try one or two on a small, low-risk project. You’ll know pretty quickly whether something feels natural or if it just adds more friction. And when you find the one that fits, it tends to blend into the background and become part of your routine.
In the end, the best choice is the one that keeps things moving without adding noise.
