The one-page guide to platform engineering vendors

Cloud infrastructure management edition

Let’s be honest: most cloud infrastructure management tools promise the world, then hand you a glorified dashboard that needs nonstop babysitting.

Terraform Cloud, Firefly, Env0, and Spacelift all tackle enterprise-scale infrastructure challenges (like resource sprawl, multi-cloud management, IaC adoption, drift prevention, and governance) — but with fundamentally different approaches, and varying levels of impact on your day-to-day.

Here’s how to find the best platform engineering vendor for your team.

Terraform Cloud

When your CI/CD pipeline only speaks Terraform

Let's be real. HashiCorp built an empire on Terraform, and Terraform Cloud is their managed offering. If you're all-in on HCL and never plan to stray, it's… serviceable.

Terraform Cloud is exactly what you'd expect from HashiCorp: great at running Terraform, but arguably uninterested in the broader DevOps lifecycle. Great for small teams who've already tackled the hard parts of their infrastructure automation, but a partial solution —at best— for complex environments.

What Terraform Cloud handles

Terraform execution: solid running of Terraform plans and applies

State management: secure, reliable remote state storage with versioning

Policy guardrails: basic policy checks through Sentinel

Variable management: secure handling of variables across workspaces

What you're still responsible for

Find unmanaged resources: no discovery capabilities to help identify what's not in code

Generate IaC: no assistance turning existing cloud resources into Terraform

Comprehensive drift management: only detects drift during scheduled or manual plan runs

Fix drift issues: no automated remediation — you'll write the fixes manually

Asset inventory: no unified inventory of cloud resources and their state

Env0

The DevOps platform that gorgets about Day 2 operations

Env0 gets a lot right with multi-IaC orchestration and some decent cost controls, but falls into the classic DevOps trap of focusing on deployment while ignoring the operational reality.

If your primary pain point is orchestration across multiple IaC tools, Env0 might be your answer. But if you're dealing with sprawling infrastructure, unmanaged resources, and comprehensive governance needs, you'll quickly hit the limits of what Env0 can solve.

What Env0 Cloud handles

Multi-IaC support: works with Terraform, Pulumi, and CloudFormation

Environment management: flexible environment organization and controls

Cost estimation: provides cost projections for infrastructure changes (but it’s dependent on Infracost)

Custom workflows: allows for customized deployment processes

What you're still responsible for

Discovering cloud resources: no automated scanning — you'll need to manually identify unmanaged resources

Creating IaC definitions: no assistance with generating infrastructure code

Comprehensive governance: limited policy enforcement with no built-in policy bundles, requiring custom policies using OPA without the benefit of ready-to-use templates.

Unified asset management: no comprehensive inventory of all cloud resources

Spacelift

All about the pipeline, less about the platform

Spacelift delivers a decent CI/CD experience for infrastructure code, but seems to forget that infrastructure exists outside of Git repositories.

Spacelift is laser-focused on running infrastructure code through pipelines. But if you need comprehensive governance and visibility across your entire cloud estate —not just what's in your IaC— you'll find Spacelift addresses only a fraction of your infrastructure lifecycle management needs.

What Spacelift Cloud handles

Pipeline flexibility: highly customizable CI/CD workflows for infrastructure

Multi-IaC support: handles Terraform, Pulumi, and other IaC tools

Policy-as-Code: solid policy enforcement for deployment processes, but lacks policy bundles with pre-built compliance frameworks

Stack management: sophisticated handling of dependencies between stacks

What you're still responsible for

Discovering actual cloud state: no capabilities for scanning your live environment

Generating IaC: no tools to help codify existing infrastructure

Comprehensive resource inventory: no centralized view across your entire infrastructure

Holistic governance: limited ability to enforce policies across both IaC and cloud resources

Unified resource inventory: no centralized view across your entire infrastructure

Firefly

The complete infrastructure automation platform built for cloud reality

Firefly was built for platform engineers who deal with the messy reality of CoudOps (not the idealized GitOps world, where everything is neatly defined in code first).

Firefly is purpose-built for the reality most platform teams face: multi-cloud environments, partial IaC adoption, continuous drift, and the need for governance that doesn’t also slow down developers.

What Firefly actually solves for

Continuous cloud discovery: automatically and continuously scans your cloud providers, identifying all resources: including those created outside of IaC

Automated IaC generation: converts existing resources into proper infrastructure code with best practices applied

Complete drift management: detects both cloud-to-code and code-to-cloud drift in real-time

Intelligent remediation: AI-assisted generation of fixes with automated PR creation

Unified governance: consistent policy enforcement across both your IaC and your actual cloud resources

Comprehensive asset management: one source of truth that tracks the lifecycle and state of all cloud resources

Multi-IaC support: works with Terraform, Pulumi, CloudFormation, and Kubernetes manifests

Four tools, one pricing reality check

All these tools cost money, but you won’t always get the same bang for your buck. Here's the real deal on pricing models:

Explore Firefly pricing

Terraform Cloud

Base pricing seems reasonable until you need the enterprise features that actually matter. Then, prepare for sticker shock.

Env0

The per-environment model can get expensive as you scale. Great for small-to-medium setups, punishing at scale.

Spacelift

The stack-based pricing is straightforward but creates odd incentives to minimize stack count, which isn't always architecturally sound.

Firefly

Resource-based pricing aligns with the value you get. Not the cheapest for tiny deployments, but predictable and fair as you scale.
