The short version

  • Each has a real cost: Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.; SolidStart smaller ecosystem compared to Next.js or Remix due to relative newness
  • They diverge on capability: Atlantis covers Pull request plans, SolidStart covers Fine-grained reactivity.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Atlantis

  • There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
  • It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
  • It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
  • Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

SolidStart

  • Smaller ecosystem compared to Next.js or Remix due to relative newness
  • SolidJS less familiar to developers with React experience
  • Community documentation not as extensive as larger frameworks
  • Limited third-party UI component libraries compared to React ecosystem

Which is cheaper, Atlantis or SolidStart?
Atlantis starts at Free and SolidStart at Free.
Does Atlantis or SolidStart run on more platforms?
Atlantis runs on Linux, Docker, Kubernetes, Self-hosted. SolidStart runs on Web.
Can I use Atlantis for free?
Both have a free tier, so you can try either at no cost before committing.
What is Atlantis best used for?
Atlantis is most often used for making terraform review meaningful by putting the actual plan output in front of the approver, removing local applies and the credential sprawl that comes with every engineer holding production keys, getting pull request driven infrastructure without paying a per-user subscription for a hosted platform, enforcing conftest policies as a blocking check before an apply can run. Of those, making terraform review meaningful by putting the actual plan output in front of the approver and removing local applies and the credential sprawl that comes with every engineer holding production keys are not what SolidStart is typically brought in for.

Answered from the vendors’ own pages

Atlantis: Is there a company behind Atlantis?

No. It runs as a series of LF Projects under the Linux Foundation and is maintained by volunteers. There is no vendor to buy support from and no service level agreement.

SolidStart: What is SolidJS and how does it differ from React?

SolidJS uses fine-grained reactivity and automatic dependency tracking instead of React's virtual DOM, resulting in smaller bundles and better performance.

Source
Atlantis: Is it a CNCF project?

No. It uses a channel in the CNCF Slack, which is often misread as membership, but the project sits under LF Projects rather than the CNCF.

SolidStart: How many deployment platforms does SolidStart support?

SolidStart supports over 20 deployment platforms including Cloudflare, Netlify, Vercel, Deno, AWS, and Azure through Vite plugins.

Source
Atlantis: Does it work with OpenTofu?

Yes, there is a dedicated integration guide alongside Terraform, and it also has configuration for working with hosted Terraform backends.

SolidStart: Can I use TanStack Router with SolidStart?

Yes, SolidStart supports using either the official Solid Router or TanStack Router depending on project requirements.

Source
Atlantis: What does it not do that a paid platform does?

Drift detection, cost estimation, a managed state and run interface, and a real policy engine. Atlantis does pull request plan and apply well and stops there.
